Electrical Connection; Initial Operation - habitat et jardin 1490 121320 Manual De Instrucciones

Damage to the heat pump caused by failure to observe this instruction is not covered by the warranty.

3.5 Electrical connection

Note: Although the heat pump is electrically isolated from the rest of the swimming pool system, this only
prevents the flow of electrical current to or from the water in the pool. Earthing is still required for protection
against short-circuits inside the unit. Always provide a good earth connection.
Before connecting the unit, verify that the supply voltage matches the operating voltage of the heat pump.
The RCD plug has been included with power cable, which can offer electrical protection.

3.6 Initial operation

Note: 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, the unit will start up after the time delay expires.
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.
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
