3.8 Initial operation
Note: In order to heat the water in the pool (or hot tub), the filter pump must be running to cause the
water to circulate through the heat pump. The heat pump will not start up if the water is not
circulating.
After all connections have been made and checked, carry out the following procedure:
1. Switch on the filter pump. Check for leaks and verify that water is flowing from and to the swimming pool.
2. Connect power to the heat pump and press the On/Off button on the electronic control panel. The
unit will start up after the time delay expires (see below).
3. After a few minutes, check whether the air blowing out of the unit is cooler.
4. When turn off the filter pump , the unit should also turn off automatically , if not, then adjust the flow
switch.
Depending on the initial temperature of the water in the swimming pool and the air temperature, it may take
several days to heat the water to the desired temperature. A good swimming pool cover can dramatically
reduce the required length of time.
Water Flow Switch:
It is equipped with a flow switch for protecting the HP unit running with adequate water flow rate .It will turn o
n when the pool pump runs and shut it off when the pump shuts off.
Time delay - The heat pump has a built-in 3-minute start-up delay to protect the circuitry and avoid
excessive contact wear. The unit will restart automatically after this time delay expires. Even a brief power
interruption will trigger this time delay and prevent the unit from restarting immediately. Additional power
interruptions during this delay period do not affect the 3-minute duration of the delay.
3.9 Condensation
The air drawn into the heat pump is strongly cooled by the operation of the heat pump for heating the pool
water, which may cause condensation on the fins of the evaporator. The amount of condensation may be as
much as several litres per hour at high relative humidity. This is sometimes mistakenly regarded as a water
leak.
3.10 Operating modes for optimal use
- POWERFUL: Used primarily at the beginning of the season because this mode allows very rapid temperature rise
- SMART: The heat pump has completed its primary task, in this mode; the heat pump is in a position to maintain the
pool water in an energy efficient manner. By automatically adjusting speed of compressor and fan the heat pump
delivers a better return.
- SILENT: In the summer months when the heat output is minimal required, the heat pump in this mode is even more
profitable. Added benefit; when the heat pump heats. It goes with minimal noise load.
