INSTALLING THE CHILLER LINES WITH R32 COOLANT GAS

The MAGIS HERCULES PRO 4-6-9 cooling circuit uses the
refrigerant R32, therefore, it is necessary to take some measures
for the proper operation of the machine:
- The R32 is a high pressure refrigerant, the pipes and other
parts subject to pressure must be compliant and suitable for
the refrigerant itself. Therefore, the pipes must be certified
for cooling and it is necessary to observe the methods of in-
stallation stated on the instruction manual supplied with the
product.
- Only use clean pipes with no harmful elements, oxides, dust,
traces of iron or moisture.
- The foreign materials inside the pipes (including manufacturing
oil) must be ≤ 30mg/10 m.
- Only use equipment and fittings for R32.
- The length of the pipes between the outdoor and indoor units
and the difference must not exceed the specified limits. The
maximum lengths of the chiller lines are listed below, based
on the condensing unit model and the type of installation:
AUDAX PRO 4 and 6 V2
A ≤ 30 m
H1 ≤ 20 m
H2 ≤ 15 m
NOTE: it is recommendable to provide for a siphon in the
immediate vicinity of the outdoor condensing unit on the gas
line pipe (pipe with larger diameter).
If the length of the chiller line is greater than the one given
in the machine pre-load, it is recommendable to provide for a
siphon halfway.
A siphon is also recommendable in the event of installation with
drops between the outdoor condensing unit and indoor unit.
