The Refrigerant R290

 To realize the function of the air conditioner unit, a special refrigerant circulates in the

system. The refrigerant is the fluoride R290 = 3 GWP (Global warming potential). This

refrigerant is flammable and inodorous. It can lead to explosions under certain

conditions, however the flammability of this refrigerant is very low and it can be ignited

only by fire.

 Compared to other common refrigerants, R290 is a non-polluting refrigerant with no

harm to the ozonosphere and a no effect upon the greenhouse effect. R290 has very

good thermodynamic features which lead to a really high energy efficiency. The units

therefore need less filling.

Warning:

Do not try to accelerate the defrosting process or to clean the appliance in different ways other

than those recommended by the manufacturer. Should repair be necessary, contact your

nearest authorized Service Centre. Any repairs carried out by unqualified personnel may be

dangerous. The appliance has to be stored in a room that doesn’t have any continuously

operating ignition sources. (for example: open flames, an operating gas appliance or an

operating electric heater.) Do not pierce or burn.

Appliance has to be installed, used and stored in a room with a floor area larger than 4 m2.

For repairs, strictly follow manufacturer’s instructions only for appliances filled with R290

flammable gas. Be aware that refrigerants do not have any odour.

The following space must be maintained to ensure the operating efficiency of the dehumidifier.

OPERATING INSTRUCTIONS

APPLIANCE START-UP

Place the product on a flat and stable heat-resistant surface, at least 1 metre away from flammable or heat-sensitive

materials and 50 cm away from walls or other obstructions.

Make sure the water tank is in the correct position

Connect the power cord to a suitable electric socket (220-240V～/1/50Hz).

Turn the appliance on with POWER on the control panel. The unit emits a sound signal and is in standby, the colored

LED on the front panel lights up. The display shows the humidity% detected in the room, therefore set a humidity %

lower than at least 3% compared to that in the room to make the dehumidifier work.

The dehumidifier is designed to operate at ambient temperatures from + 5°C to + 35°C.

If it is operated at low temperatures, ice may form on the evaporator, degrading its operation.

When this happens, the dehumidifier goes into defrost mode. The compressor stops, but the fan continues running.

The defrosting operation may start up and operate for some minutes; during the defrosting operation, the dehumidification

function may intermit: please don’t turn off the switch or pull out the power plug of the dehumidifier.

We recommend not using the dehumidifier in room temperatures lower than 5°C.

Do not remove the tank when the unit is in operation.

If you wish to make continuous draining of condensate, follow the instructions in the dedicated paragraph.

OPERATING PRECAUTIONS

The dehumidifier starts only if the humidity level in the room is higher than 3% the set one.

The dehumidifier will continue to operate until the set humidity level is reached, except for any interruptions due

to filling the tank.

When the water tank is full, the compressor stops running immediately and dehumidification stops; the fan stops after 3

minutes. Empty the tank and reposition it: after carrying out these operations, the unit will start operating again.

ATTENTION:

After each interruption of operation, at least 3 minutes must elapse before the dehumidifier restarts: this start-

up delay protects the compressor from damage.

If, on the other hand, the humidity% set is higher than that present in the room, the dehumidifier will not start.

If, after following the instructions for starting the dehumidifier, the dehumidifier does not start and the (POWER) symbol

does not light up, or the dehumidifier stops without reason, check that the condition of the plug and the power cord are

good. Once this is done, wait 10 minutes and then restart the dehumidifier.

If, even after 10 minutes, the dehumidifier does not start, or if the cable or the plug are damaged, switch off the

dehumidifier and contact a technical assistance center.

WARNING:

When the dehumidifier is running, the compressor produces heat and the appliance emits warm air into the

room. The room temperature will therefore tend to increase. This is completely normal.

Specialist’s Manual

Aptitude requirement for maintenance man (repairs. should be done only be specialists).

a) Any person who is involved with working on or breaking into a refrigerant circuit should hold a current valid certificate

from an industry-accredited assessment authority, which authorises their competence to handle refrigerants safely in

accordance with an industry recognised assessment specifìcation.

b) Servicing shall only be performed as recommended by the equipment manufacturer. Maintenance and repair requiring

the assistance of other skilled personnel shall be carried out under the supevision of the person competent in the use of

flammable refrigerants.

table a - Maximum charge (kg)

Prior to beginning work on systems containing flammable refrigerants, safety checks are necessary to ensure that the

risk of ignition is minimised. For repair to the refrigerating system, the following precautions shall be complied with prior

to conducting work on the system.

 Work procedure

Work shall be undertaken under a controlled procedure so as to minimise the risk of a flammable gas or vapour being

present while the work is being performed.

 General work area

AII maintenance staff and others working in the local area shall be instructed on the nature of work being carried out.

Work in confined spaces shall be avoided. The area around the workspace shall be sectioned off. Ensure that the

conditions within the area have been made safe by control of flammable material.

 Checking for presence of refrigerant

The area shall be checked with an appropriate refrigerant detector prior to and during work, to ensure the technician is

aware of potentially toxic or flammable atmospheres. Ensure that the leak detection equipment being used is suitable for

use with all applicable refrigerants, i.e. non-sparking, adequately sealed or intrinsically safe.

 Presence of fire extinguisher

lf any hot work is to be conducted on the refrigeration equipment or any associated parts, appropriate fire extinguishing

equipment shall be available to hand. Have a dry powder or CO2 fire extinguisher adjacent to the charging area.

 No ignition sources

No person carrying out work in relation to a refrigeration system which involves exposing any pipe work shall use any

sources of ignition in such a manner that it may lead to the risk of fire or explosion. AII possible ignition sources,

including cigarette smoking, should be kept sufficiently far away from the site of installation, repairing, removing and

disposal, during which refrigerant can possibly be released to the surrounding space. Prior to work taking place, the area

around the equipment is to be surveyed to make sure that there are no flammable hazards or ignition risks. "No

Smoking" signs shall be displayed.

 Ventilated area

Ensure that the area is in the open or that it is adequately ventilated before breaking into the system or conducting any

hot work. A degree of ventilation shall continue during the period that the work is carried out. The ventilation should

safely disperse any released refrigerant and preferably expel it externally into the atmosphere.

 Checks to the refrigeration equipment

Where electrical components are being changed, they shall be fit for the purpose and to the correct specification. At all

times the manufacturer's maintenance and service guidelines shall be followed. lf in doubt, consult the manufacturer's

technical department for assistance.

The following checks shall be applied to installations using flammable refrigerants:

---The actual refrigerant charge is in accordance with the room size within which the refrigerant containing parts are

installed;

---The ventilation machinery and outlets are operating adequately and are not obstructed;

---lf an indirect refrigerating circuit is being used, the secondary circuit shall be checked for the presence of refrigerant;

---Marking to the equipment continues to be visible and legible. Markings and signs that are illegible shall be corrected;

---Refrigeration pipe or components are installed in a position where they are unlikely to be exposed to any substance

which may corrode refrigerant containing components, unless the components are constructed of materials which are

inherently resistant to being corroded or are suitably protected against being so corroded.

 Checks to electrical devices

Repair and maintenance to electrical components shall include initial safety checks and component inspection

procedures. lf a fault exists that could compromise safety, then no electrical supply shall be connected to the circuit until

it is satisfactorily dealt with. lf the fault cannot be corrected immediately but it is necessary to continue operation, an

adequate temporary solution shall be used. This shall be reported to the owner of the equipment so all parties are

advised.

lnitial safety checks shall include:

---That capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking;

V 02/22

---That no live electrical components and wiring are exposed while charging, recovering or purging the system;

---That there is continuity of earth bonding.

 Repairs to sealed components

During repairs to sealed components, all electrical supplies shall be disconnected from the equipment being worked

upon prior to any removal of sealed covers, etc. lf it is absolutely necessary to have an electrical supply to equipment

during servicing, then a permanently operating form of leak detection shall be located at the most critical point to warn of

a potentially hazardous situation.

Particular attention shall be paid to the following to ensure that by working on electrical components, the casing is not

altered in such a way that the level of protection is affected. This shall include damage to cables, excessive number of

connections, terminals not made to original specification, damage to seals, incorrect fitting of glands, etc.

• Ensure that the apparatus is mounted securely.

• Ensure that seals or sealing materials have not degraded to the point that they no longer serve the purpose of

preventing the ingress of flammable atmospheres. Replacement parts shall be in accordance with the manufacturer's

specifications.

NOTE: The use of silicon sealant can inhibit the effectiveness of some types of leak detection equipment. lntrinsically

safe components do not have to be isolated prior to working on them.

Repair to intrinsically safe components

Do not apply any permanent inductive or capacitance loads to the circuit without ensuring that this will not exceed the

permissible voltage and current permitted for the equipment in use.

lntrinsically safe components are the only types that can be worked on while live in the presence of a flammable

atmosphere. The test apparatus shall beat the correct rating.

Replace components only with parts specified by the manufacturer. Other parts may result in the ignition of refrigerant in

the atmosphere from a leak.

Cabling

Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges or any other

adverse environmental effects. The check shall also take into account the effects of aging or continual vibration from

sources such as compressors or fans.

Detection of flammable refrigerants

Under no circumstances shall potential sources of ignition be used in the searching for or detection of refrigerant leaks. A

halide torch (or any other detector using a naked flame) shall not be used.

Leak detection methods

The following leak detection methods are deemed acceptable for all refrigerant systems.

Electronic leak detectors may be used to detect refrigerant leaks but, in the case of flammable refrigerants, the sensitivity

may not be adequate, or may need re-calibration.

(Detection equipment shall be calibrated in a refrigerant-free area.) Ensure that the detector is not a potential source of

ignition and is suitable for the refrigerant used.

Leak detection equipment shall be set at a percentage of the LFL of the refrigerant and shall be calibrated to the

refrigerant employed, and the appropriate percentage of gas (25 % maximum) is confirmed.

Leak detection fluids are suitable for use with most refrigerants but the use of detergents containing chiarine shall be

avoided as the chiarine may react with the refrigerant and corrode the copper pipe-work. If a leak is suspected, all naked

flames shall be removed/extinguished.

If a leakage of refrigerant is found which requires brazing, all of the refrigerant shall be recovered from the system, or

isolated (by means of shut off valves) in a part of the system remote from the leak. For appliances containing flammable

refrigerants, oxygen free nitrogen (OFN) shall then be purged through the system both before and during the brazing

process.

Removal and evacuation

When breaking into the refrigerant circuit to make repairs or for any other purpose conventional procedures shall be

used. However, for flammable refrigerants it is important that best practice is followed since flammability is a

consideration. The following procedure shall be adhered to:

• remove refrigerant;

• purge the circuit with inert gas; evacuate;

• purge again with inert gas;

• open the circuit by cutting or brazing.

The refrigerant charge shall be recovered into the correct recovery cylinders.

For appliances containing flammable refrigerants, the system shall be flushed with OFN to render the unit safe. This

process may need to be repeated several times. Compressed air or oxygen shall not be used for purging refrigerant

systems.

For appliances containing flammable refrigerants, flushing shall be achieved by breaking the vacuum in the system with

OFN and continuing to fill until the working pressure is achieved, then venting to atmosphere, and finally pulling down to

a vacuum. This process shall be repeated until no refrigerant is within the system. When the final OFN charge is used,

the system shall be vented down to atmospheric pressure to enable work to take place. This operation is absolutely vital

if brazing operations on the pipe-work are to take place.

Ensure that the outlet for the vacuum pump is not close to any ignition sources and that ventilation is available.

Charging procedures

In addition to conventional charging procedures, the following requirements shall be followed.

V 02/22

- Ensure that contamination of different refrigerants does not occur when using charging equipment. Hoses or

lines shall be as short as possible to minimise the amount of refrigerant contained in them.

- Cylinders shall be kept upright.

- Ensure that the refrigeration system is earthed prior to charging the system with refrigerant.

- Label the system when charging is complete (if not already).

- Extreme care shall be taken not to overfill the refrigeration system.

Prior to recharging the system, it shall be pressure-tested with the appropriate purging gas.

The system shall be leak-tested on completion of charging but prior to commissioning. A follow up leak test shall be

carried out prior to leaving the site.

Decommissioning

Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and all its

detail. lt is recommended good practice that all refrigerants are recovered safely. Prior to the task being carried out, an oil

and refrigerant sample shall be taken in case analysis is required prior to re-use of reclaimed refrigerant. lt is essential

that electrical power is available before the task is commenced.

a. Become familiar with the equipment and its operation.

b. Isolate system electrically.

c. Before attempting the procedure, ensure that:

• mechanical handling equipment is available, if required, for handling refrigerant cylinders;

• all personal protective equipment is available and being used correctly;

• the recovery process is supervised at all times by a competent person;

• recovery equipment and cylinders conform to the appropriate standards.

d. Pump down refrigerant system, if possible.

e. lf a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the

system.

f. Make sure that cylinder is situated on the scales before recovery takes place.

g. Start the recovery machine and operate in accordance with manufacturer's instructions

h. Do not overfill cylinders. (No more than 80 % volume liquid charge).

i. Do not exceed the maximum working pressure of the cylinder, even temporarily.

j. When the cylinders have been filled correctly and the process completed, make sure that the cylinders and the

equipment are removed from site promptly and all isolation valves on the equipment are closed off.

k. Recovered refrigerant shall not be charged into another refrigeration system unless it has been cleaned and checked.

Labelling

Equipment shall be labelled stating that it has been de-commissioned and emptied of refrigerant. The label shall be

dated and signed. For appliances containing flammable refrigerants, ensure that there are labels on the equipment

stating the equipment contains flammable refrigerant.

Recovery

When removing refrigerant from a system, either for servicing or decommissioning, it is recommended good practice that

all refrigerants are removed safely.

When transferring refrigerant into cylinders, ensure that only appropriate refrigerant recovery cylinders are employed.

Ensure that the correct number of cylinders for holding the total system charge are available. AII cylinders to be used are

designated for the recovered refrigerant and labelled for that refrigerant (i.e. special cylinders for the recovery of

refrigerant). Cylinders shall be complete with pressure-relief valve and assodated shut-off valves in good working order.

Empty recovery cylinders are evacuated and, if possible, cooled before recovery occurs.

The recovery equipment shall be in good working order with a set of instructions concerning the equipment that is at

hand and shall be suitable for the recovery of all appropriate refrigerants including, when applicable, flammable

refrigerants. In addition, a set of calibrated weighing scales shall be available and in good working order. Hoses shall be

complete with leak-free disconnect couplings and in good condition. Before using the recovery machine, check that it is

in satisfactory working order, has been properly maintained and that any associated electrical components are sealed to

prevent ignition in the event of a refrigerant release. Consult manufacturer if in doubt.

The recovered refrigerant shall be returned to the refrigerant supplier in the correct recovery cylinder, and the relevant

waste transfer note arranged. Do not mix refrigerants in recovery units and especially not in cylinders.

lf compressors or compressor oils are to be removed, ensure that they have been evacuated to an acceptable level to

make certain that flammable refrigerant does not remain within the lubricant. The evacuation process shall be carried out

prior to returning the compressor to the suppliers. Only electric heating to the compressor body shall be employed to
