AUDAX PRO 4 V2 Ø 6.35 - 1/4" ≤ 15 m 20 g/m
AUDAX PRO 6 V2 Ø 6.35 - 1/4" ≤ 15 m 20 g/m
AUDAX PRO 9 V2 Ø 6.35 - 1/4" ≤ 15 m 20 g/m
NOTE: If you have already prepared chiller pipes on the 3/8"
(Ø 9.52 mm) instead of 1/4" (Ø 6.35 mm) liquid line, it should
be noted that up to 7 m the machine works correctly without
having to add coolant gas, if you exceed this length, you must
add 50 g/m linear, but never exceed the total charge of 1.84 kg
of R32 coolant (take into account the amount already preloaded
in the machine).
N.B.: To avoid breaking the compressor, do not top-up the
coolant beyond the specied amount.
Topping up the coolant load.
Below is the default factory base load:
MAGIS COMBO V2 models with R32 coolant gas:
- AUDAX PRO 4 V2 = 1.2 kg
- AUDAX PRO 6 V2 = 1.2 kg
- AUDAX PRO 9 V2 = 1.4 kg
e top-up depends on the total length and diameter of the pipes.
All the default factory loads are determined as follows, depending
on the standard length of the pipes (see table below).
If the used pipes are longer than stated below, the load must
be topped-up in the manner and quantities described in the
instruction manual supplied with the product.

NOTE: e insulation cannot be interrupted and for this reason,
its junctions must be sealed with adhesive to prevent moisture
from getting in.
Should the insulation be exposed to sunlight, it must be protected
by wrapping it with electrical tape or material suitable for this
type of application.
e insulation must be laid without its thickness being reduced
in the bends and supports of the pipes.
Selecting chiller line insulation.
- e gas and liquid chiller lines must be insulated with materials
selected based on their respective diameters.
- Standard insulation is required at a temperature of 30°C with
85% relative humidity. Should the thermal-hygrometric con-
ditions of the air be harsher, you must use insulations that can
be selected from the table below.
