Water Quality; Heating; Temperature Rise Phase; Maintaining The Temperature - Polytropic XXS Manual De Instrucciones

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.

Maintaining the temperature

Once the set temperature is reached, you may reduce the filtration period according to the temperature requirements
(8 to 10 hours a day minimum during the summer). The heat pump will re-start automatically when necessary.
The minimum working time depends of the season; contact your distributor for more information.
If the temperature decreases and the machine work every time the filtration pump is on: increase the filtration time.
A thermal pool cover is very important in order to avoid unnecessary heat loss.
IMPORTANT: An uncovered pool will lose 4 times more heat than a covered pool.
The heat pump working is calculated for a covered swimming pool.

Maintenance (by a qualified technician)

Before any maintenance operation, the heat pump must be completely stopped for few minutes before connecting
pressure controllers. This is because high pressure and temperature inside the heat pump could be harmful.
Please check the following on a monthly basis:
•
Check and clean the evaporator (with a soft brush or water jet).
Do not use high pressure cleaner.
•
Check all electrical and ground connections.
•
Check that all electrical connections and terminals are securely connected.
•
Check gas pressure (when heat pump is stopped, manometer must indicate a pressure higher than 0.5)
Please check the following points yearly:
•
Check settings.
•
Check securities.
•
Check all electrical connections and ground.
•
Check condenser cleanliness.
•
Use soft soap and water to clean the heat pump casing.
Do not use solvents.
