Time delay:
The heat pump is equipped with a built-in 3-minute protection against restart. Time delay control is an
integral part of the control circuit, which limits restart cycles and contactor clicking.
Time delay automatically restarts the heat pump approximately 3 minutes after each interruption of the
control circuit. Even a short power failure will activate the 3-minute restart delay and prevent the unit from
activating before the expiry of a period of 3 minutes.
6.1 Heat pump winterization
IMPORTANT:
If essential measures to prepare the heat pump for winter are not taken, the heat pump could
be damaged, which will void the warranty.
The heat pump, filtration pump, and all installed technology of the swimming pool must not be exposed to
temperatures below the freezing point. It is necessary to remove all water from this whole system (technology),
especially the heat and circulating pump, in an appropriate manner.
WE RECOMMEND DOING THE FOLLOWING:
1. Disconnect the power supply to the heat pump.
2. Close the water inlet to the heat pump: completely close valves 2 and 3 in the bypass.
3. Disconnect the connection parts of the heat pump for intake and outlet of water and allow the water to
drain from the heat pump. In the winter season, it is recommended to fit the disconnected heat pump in
a place where temperatures will not fall below freezing point. Warning: always make sure that the water
is fully drained from the heat pump.
4. Loosely reconnect the connection parts for water intake and outlet to/from the heat pump in order to
avoid any pollutants being deposited in the pipes. This is only the case when you have no possibility to
store the heat pump according to item 3.
6.2 Starting up the heat pump again after winter
Before starting the heat pump after winter, first check the technological system (pipes) for passage through.
Also check whether or not the technological parts show any mechanical or other damage.
1. First check whether or not there are any pollutants in the pipes and whether or not there are any
structural problems.
2. Check whether or not the connection parts for water intake and outlet are properly secured to the heat
pump.
3. Start up the filtration pump in order to start the flow of water to the heat pump.
4. Reconnect the power supply to the heat pump and switch it on. Fully open valves 2 and 3 of the bypass.
Keep the circulating pump running until it is full of water. On initial startup, there is bound to be air
present in the technology.
