exchanger of the unit, and shall be cleaned regularly.
(9) All water system pipelines, valves and pipe joints must be laid with insulation
layer to reduce heat loss. Common insulation materials include soft
polyethylene foam (PEF), glass wool, rubber insulation cotton, and the
thickness of insulation layer shall be ≥30mm.
3.5.2 Water Supply Pipeline Connection
The heat pump unit is equipped with two pipe joints (PVC Ф50 mm), which are
used to connect the pipeline from the filter pump and the water outlet pipeline, and
connect to the circulating hot water system of the swimming pool.
To guarantee the safe usage of unit, a reduction valve should be installed in the
water inlet pipe if the water inlet pressure exceeds 0.5MPa.
Note: The water entering the unit must be the water passing through the
swimming pool filter to prevent the impurities from blocking the heat exchanger of
the heat pump unit, and the swimming pool disinfection device must be installed at
the downstream of the water outlet pipeline of the heat pump unit to prevent the
chemical composition of the disinfection device from affecting the heat exchanger of
the unit.
