Inspection and Service
Venus
domestic heat pump water heaters are designed and built to provide long life
performance, when installed and operated properly under normal conditions. Periodic
inspections are important to keep your heat pump running safely and efficiently.
Owner Inspection
Venus
recommends that inspections on heat pumps are done frequently, especially after
abnormal weather conditions. 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 top and surrounding areas of the heat pump clear of debris.
3.
Keep all plants and shrubs trimmed and away from the heat pump especially the
area before the fan.
4. Keep lawn sprinklers from spraying on the heat pump to prevent corrosion and
damage.
5.
Ensure that the ground wire is always properly connected.
6. The f
ilter must be maintained on a regular basis in order to ensure clean and
healthy water to protect the heat pump from damaging.
