To maintain performance, it is recommended to have the device inspected by a qualified person
HYHU\
WZR\HDUV
• All intervention on the refrigerating circuit
m
ust be done by a qualified
person with a category 1 certificate of aptitude.
• The release of the refrigerant into the at
m
osphere is not per
m
itted,
the refrigerant recovery
m
ust be done before any intervention on the
refrigeration circuit.
• Turn D.W.H.P off before opening it.
• Wait for the co
m
plete stop of the ventilator before any intervention.
•Make the anode inspection every year
• Do not spring water on electical parts
4 - MAINTENANCE AND REPAIR
4.1 - Water circuit / condensate draining
The inspection of the water circuit is limited to the inspection of the filters and of eventual leaks. Clean
or replace the dirty filters.
Check that the condensate draining is operating correctly:
- Remove the upper cover (see section “Peak time / off-peak time functioning”).
- Verify that the evacuation orifice is not blocked.
- Clean the condensate recovery container where deposits brought in by the air can accumulate.
- Clean the condensate tube.

During maintenance or the shutting down of
':+3
, follow the environmental protection
rules with respect to recovery, recycling and disposal of consumable parts and components.
The pressure limiter has to be checked and cleaned, régularly to prevent any disfunctionning.
Check the leak tighteness on every fitting, flange and hydraulic connections.
4.3 - Anti-corrosion anode
The anti-corrosion anode is installed in the hot water tank and must be regularly electrically tested as well
as a minimum of every years after the activation of
':+3
. Replace it if necessary.
- Drain water out of the tank
- Unscrew the anode from the tank
- Check the anode diameter at the thinest point : diameter must be higher than 15mm
- Change the anode if its diameter is less than 15mm (the initial diameter being 33mm)
An anti-corrosion anode in bad working condition shortens the length of
operation of the device and nullifies the warranty.
4.2 - Air intake circuit
Maintenance work is limited to the cleaning of the evaporator (at least once a year according to the
cleanliness of the air taken in). If the filters are used, check regularly that they are not dirty. Clean them if
necessary.
