7.2.3 --- R407C refrigerant units
7.2.3.1---Features of the refrigerating fluid R407C
At standard temperature and pressure it is a colourless gas
with low toxicity, non---flammable, and it has an allowed ex-
posure limit value (AEL/TLV) corresponding to 1000 ppm (av-
erage value measured on 8 hours/day). In the event of leak-
age, air the room before use.

IMPORTANT:
The charges indicated in Tab. e refer to a 2 m length for the
gas and liquid pipes: Tab. f shows the indications for longer
measures on the additional charge in grams of refrigerant
R407C by each pipe meter of the gas and liquid lines, accor-
ding to the diameters indicated in Tab. a.

The oil to be used when topping up is EMKARATE RL
32---3MA or MOBIL EAL ARTIC 22CC, if it’s unavailable use
an oil with the same characteristics (see Tab. g and Tab. h).
NEVER MIX DIFFERENT OILS TOGETHER. CLEAN THE PIP-
ING COMPLETELY BEFORE CHANGING THE TYPE OF OIL
USED.

7.3 --- Dismantling the unit
The machine has been designed and built to ensure continu-
ous operation.
The working life of some of the main components, such as
the fan and the compressor, depends on their maintenance.
If the unit has to be dismantled, this must be done by skilled
refrigerator technicians.
The refrigerating fluid and the lubricating oil in the circuit must
be disposed of in conformity with the laws in force in your
country.
7.4 --- Spare parts
We recommend the use of original spare parts.
When placing an order please refer to “Component List” en-
closed with the machine and specify the unit model and serial
no.
