1.4 HYDRONIC MODULE
CONNECTION UNIT.
- The hydraulic connection unit is standard sup-
plied with Magis Pro ErP. Make the hydraulic
connection as shown below, making sure to
protect the system flow and return pipes with
their supplied insulating sheaths.
- The R410A circuit wall connection unit is
supplied as an extra kit. Connect the circuit,
following the instructions provided in the
condensing unit instructions booklet.

1.5 HYDRAULIC CONNECTION.

Attention: in order not to void the product war-
ranty, before making unit connections, carefully
clean the heating system (pipes, radiators, etc.)
with special pickling or de-scaling products to
remove any deposits that could jeopardise proper
hydronic module operation.
A chemical treatment of the heating system water
is required, in compliance with the technical
standards in force, in order to protect the system
The hydraulic connection kit includes:
2 - adjustable expansion bolts
2 - hydronic module support hooks
1 - 3/4" storage tank unit return pipe (RU)
1 - 3/4" storage tank unit flow pipe (MU)
1 - 1/2" system filling pipe (RR)
1 - 1/2" ball valve (RR)
1 - 3/4" system return pipe (R)
1 - 3/4" system flow pipe (M)
1 - 3/4" ball valve (M)
2 - Insulating sheath for system pipes (R - M)
4 - 3/4" telescopic fittings (RU - MU - R)
Gaskets, screws and seal O-Ring
The R410A circuit wall connection kit (optional) includes:
1 - G 3/8" liquid phase chiller line pipe (LP)
1 - G 5/8" gaseous phase chiller line pipe (GP)
Already installed on the module:
1 - System interception tap with 3/4" filter (R)
and the appliance from deposits (e.g. scale),
slurry or other hazardous deposits.
Hydraulic connections must be made rationally,
using the couplings on the hydronic module
template.
Attention: Immergas declines all liability in the
event of damage caused by the inclusion of auto-
matic filling that is not its own brand.
In order to meet the system requirements es-
tablished by EN 1717 regarding the pollution
of drinking water, we recommend installing the
IMMERGAS anti-backflow kit upstream of the
hydronic unit cold water inlet connection. We
also recommend using a category 1, 2 or 3 heat
transfer fluid (ex: water + glycol) in the hydronic
unit primary circuit (CH circuit), as defined in
the EN 1717 standard.
Attention: to preserve appliance duration and
efficiency features, we recommend installing a
suitable water treatment device if the water has
features that can lead to limescale deposits.

1.6 CONNECTING THE CHILLER LINE.

As far as connecting the chiller line is concerned,
all the instructions contained in the Audax Pro
condensing unit instructions booklet must be
followed.
Make the connections directly on the hydronic
module couplings, or use the rear outlet kit
(optional).
