with regulations;
- on or near electrical components: electrician
accreditation in accordance with regulations.
Technicians who install, commission, operate and service the
unit must possess the necessary training and certifications,
understand the instructions given in this manual and be familiar
with the specific technical characteristics of the installation site.
Any work on the refrigeration circuit must meet the
requirements of EC regulation no. 842/2006.
3.4 Pressure and temperature
Test pressure (TP) : In accordance with § 5.3.2.2 a
and 6.3.3 iii of standard 378-2, the pressure test (PT)
is performed on model representative of all 3 x PS
assemblies.
Shipping temperature : min.: -20°C., max.: +65°C.
Storage temperature : -20°C., max.: +65°C.
Operating temperature : see § OPERATING RANGES.
3.5 Refrigerants
In accordance with EC regulation no. 842/2006 concerning
certain greenhouse gases, the environmental impact of
R410A, R134a and R407C fluids is:
- on the OZONE layer: NONE. ODP (Ozone Depletion
Potential) rating = 0
- on the greenhouse effect (GWP = Global Warming
Potential:
- R410A: GWP=2088
- R407C: GWP=1800
- R134a: GWP=1430
Users must have a sealing check carried out by a qualified
technician. The frequency is determined by the refrigerant
charge:
- every 12 months for units containing 3 to 30 kg of
refrigerant. (2 kg in France, edict and decree of 7 May
2007);
- every 6 months for units containing 30 to 300 kg of
refrigerant;
- every 3 months for units containing over 300 kg of
refrigerant (a leak detection system must be installed).
Users of any system containing over 3 kg of refrigerant (2
kg in France) are required to keep a log of the quantities
and types of refrigerants used, added or recovered, and to
include the dates and results of leak tests, as well as the
name of the technician and company performing the test.
A sealing check must be carried out one month after any repairs to
a circuit containing refrigerant.
System users are responsible for collecting used refrigerant
