MAINTENANCE

• You should check the water supply system regularly to avoid the air entering into water system and occurrence of low water flow, it would reduce the performance and reliability of the heat pump.
• Clean your pools and filtration system regularly to avoid the damage of the unit because of a dirty or clogged filter.
• Discharge the water from the bottom of the water pump if the heat pump will stop running for a long time (specially in winter).
• On any other moment, check the water flow to confirm there is enough water before the unit starts to run again.

After the unit is conditioned in winter, it is preferred to cover the unit with the special winter heat pump cover.
