NeoPAC

Winter setting

When you are winterising your pool system, you must:
• Turn the pool heat pump off
• Close downstream and upstream valves of the by-pass system.
• Drain the exchanger to prevent any risk of freezing.
• Open completely the downstream and upstream valves to empty the heat exchanger
tank before closing them.
• Cover the heat pump with a water-proof cover.
• A special cover designed for each heat pump model can be provided as an option.

Water quality

The water quality must be within the following limits
Chlorine concentration less than 2.5 ppm
pH level from 6.9 to 8
In case of strong shock treatment, isolate the appliance using the downstream and upstream
valves of the by-pass system. Once the treatment has finished, set the by-pass valves to their
initial position prior to the treatment.
VERY IMPORTANT: the warranty will be invalidated if chemical concentration levels
are not maintained within the limits mentioned.
Never make the injection of chemicals (chlorine, acid, etc.) directly in the filtration pump
strainer.
It could be a highly corrosive product that would irreversibly destroy your appliance.

Heating

Temperature rise phase
As soon as you wish to re-start your swimming pool at the beginning of the season, isolate
your heat pump from the filtration circuit:
• Close downstream and upstream by-pass valves.
• Open setting valve.
• Then proceed with all the usual initial operations (water filling, back-wash of the filter...,
• Turn the filtration pump on.
• Turn pool heat pump on, set temperature, set water flow, open the by pass valves.
• Cover the pool with solar cover or other.
Leave the pool system and pool heat pump working permanently until the pool has reached
the required temperature (it will take approximately 36 hours to 1 week).
Don't forget to set the water flow and required temperatures.
The time for the pool temperature to increase depends on the exposure of swimming pool to
wind, sun and the pool environment as well as the heat pump size.
