6 Maintenance
6.1 Daily Maintenance
(1) In the use season of the pool heat pump unit, it is recommended to clean the
filter every week.
(2) In the use season of the swimming pool, check that the electrical connection of
the heat pump unit is safe and reliable, the water system pipeline is smooth
and free of water leakage, there are no obstacles around the unit that affect
the heat exchange, and the radiator-fan heat exchanger is clean before use.
(3) Thermal insulation: The water temperature of the swimming pool is affected by
environmental temperature, surface wind speed, heat conduction of the pool
materials and other factors. In order to avoid heat loss, the protective heat
shield is usually used to cover the pool during the shutdown stage to avoid
heat loss and reduce the energy consumption of the pool unit.
6.2 Maintenance in Winter
When using this product in winter (the temperature may be lower than 0
),
please ensure that the unit is always powered on, the water supply for the unit is
continuous and the water pipe is wrapped with insulation layer; If it is not used in
winter or the unit fails to use due to a fault, please be sure to drain the water in the
water-side heat exchanger and connecting pipe of the unit immediately after the
power failure to prevent the stored water from freezing and cracking the equipment
and pipe.
After disconnecting the water inlet/outlet pipes, draining all of the water of heat
exchanger and pipeline, seal the pipe inlet/outlet to prevent debris from entering
and assure a normal use next time.
