The described checks must be executed at least once a year
by qualified personnel.
Water pressure
Check if the water pressure is above 1 bar. If necessary
add water.
Water filter
Clean the water filter.
Water pressure relief valve
Check for correct operation of the pressure relief valve by
turning the black knob on the valve counter-clockWise:
If you do not hear a clacking sound, contact your local
dealer.
In case the water keeps running out of the unit, close both
the water inlet and outlet shut-off valves first and then
contact your local dealer.
Pressure relief valve hose
Check that the pressure relief valve hose is positioned
appropriately to drain the water.
In order to ensure optimal availability of the unit, a number of
checks and inspections on the unit and the field wiring have to
be carried out at regular intervals.
This maintenance has to be carried out by your local Clivet
technician.
DANGER
ELECTRIC SHOCK
Before carrying out any maintenance or repair activity,
always switch off the circuit breaker on the supply panel,
remove the fuses (or switch off the circuit breakers) or
open protection devices of the unit.
Make sure that before starting any maintenance or repair
activity that the power supply to the outdoor unit is
switched off.
Do not touch live parts for 10 minutes after the power
supply is turned off because of high voltage risk.
The heater for the compressor may operate even in stop
mode.
Please note that some sections of the electric
component box are hot.
Make sure you do not touch a conductive section.
Do not rinse the unit. This may cause electric shocks or
fire.
When service panels are removed, live parts can be
easily touched by accident.
Never leave the unit unattended during installation or
servicing when service panel is removed.
Backup heater vessel insulation cover
Check that the backup heater insulation cover is fastened
tightly around the backup heater vessel.
Domestic hot water tank pressure relief valve (field
supply).
Applies only to installations with a domestic hot water
tank.
Check for correct operation of the pressure relief valve on
the domestic hot water tank.
Domestic hot water tank booster heater.
Applies only to installations with a domestic hot water
tank. It is advisable to remove lime buildup on the booster
heater to extend its life span, especially in regions with
hard water.
To do so, drain the domestic hot water tank, remove the
booster heater from the domestic hot water tank and
immerse in a bucket (or similar) with lime-removing
product for 24 hours.
Unit switch box
Carry out a thorough visual inspection of the switch box
and look for obvious defects such as loose connections or
defective wiring.
Check for correct operation of contactors with an ohm
meter. All contacts of these contactors must be in open
position.
Use of glycol
Refer to chapter WATER CONNECTIONS - Use of glycol
Document the glycol concentration and the pH-value in
the system at least once a year.
A PH-value below 8.0 indicates that a significant portion of
the inhibitor has been depleted and that more inhibitor
needs to be added.
When the PH-value is below 7.0 then oxidation of the
glycol occurred, the system should be drained and flushed
thoroughly before severe damage occurs.
Make sure that the disposal of the glycol solution is done
in accordance with relevant local laws and regulations.
