Winter-ready
Failure to winterize the heat pump could cause damage to the heat pump and will void warranty.
In areas where freezing temperatures occur, you should protect your pump, filter and heat pump. Perform the
following steps to completely drain the heat pump:
1.
Turn off the electrical power to the heat pump at the main breaker panel.
2.
Shut off the water supply to the heat pump: close valves 2 and 3 on the by-pass completely.
3.
Disconnect the water inlet and outlet and let the water drain from the heat pump.
4.
Connect the inlet and outlet again to prevent dirt from entering the connections.
Spring start-up
If your heat pump has been made winter-ready, perform the following steps whilst starting the heat pump again in
spring:
1.
Inspect the system for any debris or structural problems.
2.
Connect the water inlet and outlet unions firmly.
3.
Turn on the filter pump to supply water to the heat pump. Adjust the by-pass to allow water flow through
the heat pump.
4.
Turn on the electrical power to the heat pump at the main panel.
Owner inspection
The HARMO PAC heat pumps are designed and constructed to provide long performance life when installed and
operated properly under normal conditions. Periodic inspections are important to keep your heat pump running
safely and efficiently through the years. 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 bushes trimmed and away from the heat pump.
4.
Keep lawn sprinkler heads from spraying on the heat pump to prevent corrosion and damage. Use a
deflector if needed.
5.
If the heat pump 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 heat pump.
6.
Do not use the heat pump if any part has been exposed to an excessive amount of water.
Immediately call a qualified professional technician to inspect the heat pump and replace any part of the
control system, which has been submerged.
