DISCONNECT: A disconnect means (circuit breaker, fused or un-fesed switch) should be located within
sight of and readily accessible from the unit. This is common practice on commercial and residential heat
pumps. It prevents remotely-energizing unattended equipment and permits turning off power at the unit
while the unit is being serviced.
3.Initial Startup of the unit
NOTE:
Please make sure the water pump is running in circulation with adequate rate of water flow.
Startup Procedure after Installation is completed, and please follow these steps:
(1) Turn on your filter pump ,check water leaks and verify flow of swimming pool.
(2) Turn on the electrical power supply to the unit, then press the key ON/OFF of wire controller, it should
start in several seconds.
(3) After running a few minutes make sure the air ventilation from the side (top) of the unit is cooler
(Between 5 °C and10 °C).
(4) When turn off the filter pump, the unit should also turn off automatically , if not, then adjust the flow
switch.
Allow the unit and pool pump to run 24 hours per day until the water reaches the desired
(5)
temperature. When the temperature reaches the setting value ,the HP unit will shut down, when
the pool temperature drops more than 2 °C, the heat pump will restart automatically.
Water Flow Switch:
It is equipped with a flow switch for protecting the HP unit running adequate water flow rate.
It will turn on when the pool pump runs and shut it off when the pump shuts off. If the pool water
level higher than 1 m above or below the heat pump's automatic adjustment knob, your dealer may
need to adjust its initial startup.
Time Delay:
HP unit should be equipped with a 3-minute built-in solid-state restart delay protection. Time delay
control is an integral part of the circuit control, it can eliminate restart cycling and contactor chatter.
The time delay will automatically restart the HP unit approximately 3 minutes after each control
circuit interruption. Even a brief power interruption will activate the solid state 3 minute restart
delay and prevent the unit from the starting until the 3 minutes countdown is completed.
