9. Maintenance
(1) You should check the water supply system regularly to avoid the air entering the system
and occurrence of low water flow, because it would reduce the performance and reliability of
the heat pump.
(2) Clean your pools and filtration system regularly to avoid the damage of the unit as a result
of a dirty or clogged filter.
(3) You should discharge the water from the bottom of the water pump if the heat pump will
stop running for a long time (specially during the winter season).
(4) On any other moment, you should check if the unit has enough water before the unit starts
to run again.
(5) After the unit is conditioned for the winter season, it is preferred to cover the heat pump
with the special winter heat pump cover.
(6) When the unit is running, there is always a little water discharge under the unit.
