Very Important; Heating - Polytropic PAC 16 Manuel D'instructions

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

Pool heating is composed of two phases:
• Initial temperature rise phase in which temperature increases at the
beginning of the season.
• Temperature maintenance phase
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.
