Check from time to time that the condensates are draining
properly:
- Remove the back panel
- Check the drainage hole for blockages
- Clean the condensates collection trough as deposits from air
intake may accumulate here.
- Clean the exible drainage hose
Case a : drainage from underneath
Cas b : drainage from the back
Check that the pressure relief valve is properly sealed. It should
not leak if the water pressure is under 2.5 bar.

6 - MAINTENANCE AND
REPAIRS
•In order to ensure the best performances
from your HRC
70
Heat Pump it should be
maintained.
• An annual maintenance check is recommended
on the hydraulic heating circuit, to be
carried out by a quali ed professional.
•Any work undertaken on the refrigerant
circuit MUST be carried out by a quali ed
professional with a category 1 certi cate
of aptitude
•Switch the appliance off before opening it
6.1 - General information
6.2 - Hydraulic circuit maintenance
After the appliance has been running for a few days, it is advisable
to check that the water circuit is watertight and that condensates
are draining correctly.
N.B: In case of maintenance work or decommissioning
an appliance, please respect all environmental
protection instructions concerning recovery,
recycling and disposal of consumables and
components.

6.2.2 - HRC
70
Pilot
We would advise you to have an annual maintenance check
carried out on the HRC
70
Pilot, which should be done by a
quali ed professional.
• When operating with electrical back-up, after the appliance has
been running for a few days and then at least once a year, all the
electrical power connections (switches and heating elements)
should be checked to ensure that they are properly tightened.
• Clean the valve lter
The HRC
70
Heat Pump contains type R290 refrigerant. This means
that it is not subject to the regulations on the greenhouse e ect
an does not require an annual maintenance check by a quali ed
professional.
However, we would recommend that from time to time (at least
once a year) the evaporator ns are cleaned if they have collected
leaves or dust on them. This should be done by using a vacuum
cleaner or spraying them with water.
Never clean the nned heat exchanger
with high-pressure cleaning
equipment: this could damage the ns.
In case of repair work on the HRC
70
Heat Pump, the refrigerant
circuit or the electrical box, it is important to follow the
instructions below:
Any work on the refrigerant circuit must be undertaken by a
quali ed professional with a category 1 certi cate of aptitude. It is
forbidden to release gas from the refrigerant into the atmosphere
and it is obligatory to recover the refrigerant before doing any
work on the circuit.
6.3 - Heat Pump maintenance
6.2.3 - Heating circuit maintenance
• Release any trapped air in the HRC
70
Pilot.
• Check that the whole circuit is watertight, as well as the pressure
relief valves.
• Check the hydraulic pressure. This should not be any higher than
the water pressure in the expansion vessel. It should never be
higher than 2.5 bar when hot. If the water pressure is low, check
that all of the circuitry is watertight before adding more water.
• Check the composition and condition of the water in the heating
circuit.
• Check the hydrualic circuit, cleaning the lter and checking the
water quality (pH level, anti-freeze, etc.).
