F-Gas Requirement; Equivalent - J&E Hall V3 FUSION Technical Manual

F-Gas Requirement

The models of equipment covered in this Technical Manual rely on fluorinated greenhouse gases for their functioning.
All unit models come from the factory pressurized with OFN (Oxygen Free Nitrogen) only.
In F-Gas Regulation EU 517/2014, the requirement for leak testing on the system is based on the charge size in tonnes of CO
equivalent. Which means systems with higher GWP refrigerants will need to be leak tested more frequently than those with the
same charge weight of a lower GWP refrigerant.
The GWP (Global Warming Potential) values of refrigerants which are specified for use along with the three new thresholds for
leak testing requirements based on TCO₂Eq (Tonnes CO₂ Equivalent) are as follows:
Table 14: Tonnes CO₂ Equivalent
Refrigerant GWP
R134a 1430
R407A 2107
R407F 1825
R448A 1387
R449A 1397
R452A 2140
Starting 1st January 2017, the requirement for leak detection and maintaining system logs changes from 3kg HFC to 5 tonnes
CO

equivalent.

A refrigerant charge label is supplied with each unit (inside the electrical box). The total
refrigerant charge for the system and the TCO
indelible ink and must be adhered in the proximity of the product charging port. The label
supplied will represent the refrigerants approved for use with that unit. An example of the
unit label is as follows:

CHECK
Phase(s) and neutral present?
Voltage within tolerance?
Is isolator switched on?
Is there correct voltage to
contactor coil?
Has a safety switch tripped out?
Is voltage being switched across
contactor?
Low and High pressure conditions
and current draw on overload.
Check settings of safety switches
are correct.
SOLUTION
Check/rectify
Check/rectify
If not - switch on
If yes - coil faulty. Replace
contactor/coil
If no - check for break in control
circuit or blown control fuse.
Check cause and reset
If yes - check voltage at
compressor terminals and
compressor wiring
If no - Replace the faulty contactor
Reset and rectify any abnormal
conditions or adjust switch settings
if not set correctly
