Working on the electrical panel
The tightening torques for the electrical power wires are
as follows (depending on the component to be supplied):
- single-phase starter: 1.2 Nm
- three-phase starter: 1Nm
- power switch: 1.2 Nm
Specific requirements for refrigerants
Maintenance operations on the heat pump must only be
carried out by a maintenance company whose personnel
are qualified to handle refrigerant fluids in accordance
with order CE No. 842/2006.
R410A refrigerant fluid is a gas which has the following impact
on the environment:
1/ No impact on the OZONE layer : ODP (Ozone Depletion
Potential) = 0.
2/ Impact on the greenhouse effect : GWP (Global Warming
Potential) = 1975.
- Units containing over 3 kg of refrigerant (2 kg in France,
decree and order of 7 May 2007) must be periodically checked
for leaks by qualified maintenance personnel.
- For all systems which contain over 3 kg of refrigerant (2 kg in
France), users are required to keep a log of the quantities and
types of fluids used, added and recovered as well as the dates
and results of the sealing tests, the name of the technician and
the company concerned. We strongly recommend that you
keep this log up to date.
- A leak test must be carried out one month after any leak
repairs.
- The maintenance company is responsible for collecting used
refrigerant and having it recycled, regenerated or destroyed.
4.2 Checks
Mandatory annual checks:
- Leaks on the refrigeration circuit.
- Check for loose electrical connections
- Check the glycol mix and pH. Always top up with the same
type of mix initially used.
- Check the water filters for dirt. The filters may need to be
checked more frequently.

4.4 Operating readings
Have an approved maintenance company or your installer record the operating readings and carry out the checks shown in the
table below at least once a year.
4.3 User recommendations
To ensure that the unit operates correctly, we recommend
that you sign a maintenance contract with your installer or
an approved maintenance company. Consult our list of CIAT
Authorised Technical Agents at www.ciat.fr
With the system running, check it thoroughly for any abnormal
visual signs or noises.
Check for water leaks and traces of oil around the unit.
We recommend avoiding the use of pressure
gauges on the refrigerant circuit during basic
operating checks. A temperature reading is sufficient
in most cases.
