4.3 Spring start-up
If your heat pump has been winterized, perform the following steps when starting the system in the spring:
1. Inspect the system for any debris or structural problems.
2. Connect the water inlet and outlet couplers firmly.
3. Turn on the filter pump to supply water to the heat pump. Adjust the bypass to allow water flow
through the heat pump.
4. Turn on the electrical power to the heat pump at the main breaker panel.
4.4 Owner inspection
The ECO heat pumps are designed and constructed to provide long performance life when installed and
operated properly and under normal conditions. Periodic inspection is important to keep your heat pump
running safe and efficiently. The following basic guidelines are suggested for your inspection:
1. Make sure the front of the unit is accessible for future service.
2. Keep the surrounding areas of the heat pump clear of all debris.
3. Keep all plants and shrubs trimmed and away from the heat pump.
4. Keep lawn sprinkler heads from spraying on the heat pump to prevent corrosion and damage.
5. If the unit is installed under a very sharp roof pitch or under a roof without a gutter, a gutter or
diverter should be fitted to prevent excessive water from pouring down onto the unit.
6. Do not use the heat pump if any part has been under water. Immediately call a qualified professional
technician to inspect the heat pump and replace any part of the control system that has been
submerged.
The heat pump will produce condensation(water) while in operation. The heat pump base is designed to
allow the condensation to exit through the bottom drain port. The condensation will increase as the outdoor
air humidity level increases. Check the following at regular intervals to ensure proper condensate drainage:
1. Visually inspect and clear the bottom drain port of any debris that could clog the port.
2. Keep the air intake area and discharge area clear of debris so the airflow through the heat pump is
not restricted. The cooler discharge air should not accumulate and be drawn into the side air intake
coils.
During normal operation, the heat pump produces ten to twenty liters of condensate per hour. If condensate
drainage is above this range during operation, or if water continues to drain from the base when the heat
pump is not in operation for more than an hour, a leak in the internal plumbing may have occurred. Call a
qualified heat pump technician to investigate the problem.
Note: A quick way to verify if the water running through the drain is condensation water is to shut off the
unit and keep the pool pump running. If the water stops running out of the base pan, it is condensation
water. An even quicker way is to test the drain water for chlorine. If there is no chlorine present, then it’s
condensation.
