5.9 TOPPING UP THE COOLANT LOAD.

Below is the default factory base load:
- Audax Pro 5: 1.2 kg
- Audax Pro 8 and 10: 2.0 kg
The 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:
- Audax Pro 5: ≤ 5m
- Audax Pro 8 and 10: ≤ 15m
Should the pipes used be longer, the load must
be topped up as follows.
The top-up amount depends on the total length
of the liquid line.
(g) = {(L1 - n) x 20} + {(L2 - n) x 50}
Key:
L1 - Total length of the Ø 6.35 liquid pipe,
(m)
L2 - Total length of the Ø 9.52 liquid pipe,
(m)
n - standard pipe length, see previously
listed specific value

5.10 ADDING COOLANT.

As the outdoor unit comes already equipped with
the base load, the amount to top-up depends on
the total length and diameters of the liquid pipes.
Liquid line Ø 6.35
Top-up (g) 20 g/m
Calculating the amount to top-up:
(Total length (m) of the Ø 9.52 pipes) × 50 g
+ (Total length (m) of the Ø 6.35 pipes) × 20g
Example:
20 m × 50 g/m + 20 m × 20 g/m = 1,400 g

5.11 PUTTING IN THE COOLANT.

R-410A is a blend of several coolants. For this
reason, it must be put into the chiller circuit only
in its liquid phase.
The amount of coolant to put in depends on the
length and diameters of the liquid pipes. Using
a scale is recommendable to put in the required
amount of coolant.
5.12 IMPORTANT INFORMATION ON
THE COOLANT USED
The coolant contained in this unit contains
fluorinated greenhouse gases subject to the Kyoto
Protocol. Therefore, it must not be released into
the atmosphere.
Attention:
- Inform the user if the chiller circuit contains
more than 5 tonnes of CO
fluorinated greenhouse coolant. In this case,
the system must undergo a leak check every 12
months, as required by regulation no. 517/2014.
Example: Audax Pro 2.0 kg of R-410A gas =
2.0 x 2088 (GWP) = 4.18 tonnes of CO
N.B.: if there is a leak detection system, the
minimum frequency of checks extends to every
24 months.
Checking for leaks must be done only by spe-
cialised personnel.

installer (or the person responsible for final
checks) must provide the user with a "unit
record", on which to record all the information
required by EU regulation 517/2014 of the
European Parliament and Council dated 16
April 2014 on greenhouse gas management.
- Before putting in the coolant, you must check
whether the tank in which it is contained has
a float or not, and consequently position the
tank itself (see fig. 5-14).
