EvoHeat CS-i Commercial Inverter Series Heat Pump
4.8 Electrical Connection
IMPORTANT: Always use a qualified Electrician to perform any electrical work. A licensed electrician must read the
information before connecting.
Ensure the power cable and circuit breaker are of a suitable size for the heater being installed. Also check that there
is adequate voltage and current available at the heater connection to run the unit.
Voltage range should be 220-230 volts for single phase, and 380-400 volts for 3 phase units. Voltage ranges outside
these parameters will cause heater damage and void your warranty.
1.
Ensure power is disconnected during installation or service.
2.
Always comply with the national and local electrical codes and standards.
3.
Ensure electrical cable size is adequate for heater requirements at the installation location.
4.
The heater must be equipped with a circuit breaker and isolation device.
5.
Circuit breaker must be installed between the heater and the water circulation pump if the water pump is
hard-wired into the heater. Please note recommended circuit breaker sizes make no allowance for a water
pump hard wired into the heater.
6.
The unit must be well earthed. Remove the front panel to access the electrical connection terminals of the
heater. The electrical wiring diagram is affixed to the inside of the front panel.
4.9 Initial Start-up
Note: in order for the unit to heat the pool or spa, the filter pump must be running to circulate water through the heat exchanger.
After installation is completed, follow the steps below:
1.
Turn on your filter pump. Check for water leaks and verify flow to and from the pool.
2.
Turn on the electrical power supply to the unit, then press the key ON/OFF of wire controller, it should start after
several seconds.
3.
After running a few minutes make sure the air leaving the top of the unit is cooler (between 5-10
℃
)
4.
With the unit operating turn the filter pump off. The unit should also turn off automatically.
5.
Allow the unit and pool pump to run 24 hours per day until desired pool water temperature is reached. (Note:
this may take up to several days depending on the initial water temperature and the size and location of the
pool). When the water-in temperature reaches the set temperature the unit will shut off. The unit will now
automatically restart (as long as your pool pump is running) when the pool temperature drops more than 1
℃
below the set temperature.
TIME DELAY
The unit is equipped with a 3-minute built-in solid-state restart delay included to protect control circuit components
and to eliminate restart cycling and contactor chatter. This time delay will automatically restart the 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 starting until the 5-minute countdown is completed.
Power interruptions during the delay period will have no effect on the 3-minute countdown.
