temperature during defrosting period, if the swimming pool system is frequently operates under low load,
please make sure the water capacity of the system is more than the 1/6 of the total rated flow volume per
each hour for every modules. If the waterway is short, it needs to add water storage tank. Otherwise, it
may affect the service life of the unit.
3) Instruction for water makeup: When the water level inside the expansion water tank, the water
makeup valve will open to make up water; when the water level reaches a certain water level, the water
makeup valve will be closed.
4) Instruction for heating operation: When the water temperature in the swimming pool inspected by
water tank temperature sensor is decreased to a certain temperature below set temperature, the unit will
be started up and the unit side circulating water pump will make the water inside the pipe network pass
through the water side heat exchanger and then heat it circulately. Meanwhile, swimming pool side
circulating water pump will make the water inside the swimming pool pass through removable plate-type
heat exchanger for the second time heat-exchanger. When the water temperature in the swimming pool
reaches the set temperature, the unit will stop operation. Because swimming pool system is the second
time heat-exchanging, there’s temperature difference of heat-exchanging at unit side and swimming pool
side. When setting the temperature value of temperature sensor for water tank, please try to set it 10
℃
above lower than the maximum set temperature.
5) Parallel connection quantity of unit1≤n≤16.
6) Water pump control: because the water inside pipe network and swimming pool should be heat
exchanged simultaneously, please make sure the water pump at unit side and the water pump at
swimming pool side are controlled simultaneously during installation.
7) Control of auxiliary electric heating: The auxiliary electric heating adopts pipeline electric heating,
which is controlled by ambient temperature and the unit.
8) If the unit hasn’t been used for a long time or the unit is started up for the first time, please check
the pipe network and clean it. Fill the pipe network and expansion water tank with water and then turn on
the unit.
