includes:

1.4 CONNECTION GROUP.

- The hydraulic connection unit is standard

supplied with Magis Combo Plus. Make the

hydraulic connection as shown below, making

sure to protect the system ow 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

indoor unit operation.

Treatment of the thermal system water is re-

quired by law, in order to protect the system and

the appliance from deposits (e.g., lime scale),

slurry or other hazardous deposits. Water con-

nections must be made in a rational way using the

couplings on the indoor unit template.

e safety valve outlet of the indoor unit must

be connected to a draining funnel. Otherwise,

the manufacturer of the indoor unit declines

any responsibility in case of ooding if the drain

valve cuts in.

Attention: the manufacturer declines all liability

in the event of damage caused by the installation

of an automatic lling system.

In order to meet the system requirements es-

tablished by EN 1717 regarding the pollution

of drinking water, we recommend installing the

IMMERGAS anti-backow kit upstream of the

hydronic unit cold water inlet connection. We

also recommend using a category 1, 2 or 3 heat

transfer uid (ex: water + glycol) in the hydronic

unit primary circuit (CH circuit), as dened in

the EN 1717 standard.

Attention: to preserve appliance duration and

eciency features, we recommend installing a

suitable water treatment device if the water has

features that can lead to limescale deposits.

Condensate drain. To drain the condensate pro-

duced by the appliance, it is necessary to connect

to the drainage system by means of acid conden-

sate resistant pipes, with an internal Ø of at least

13 mm. e system connecting the appliance to

the drainage system must be carried out in such

a way as to prevent occlusion and freezing of the

liquid contained in it. Before appliance ignition,

ensure that the condensate can be correctly re-

moved. Aer rst ignition, check that the drain

trap is lled with condensate (Para. 1.23). Also,

comply with national and local regulations on

discharging waste waters.

In the event condensate is not discharged into

the wastewater drainage system, a condensate

neutraliser must be installed to ensure com-

pliance with the parameters established by the

legislation in force.

Attention: if you are using one or more booster

pumps it is essential to install a hydraulic sep-

arator (not supplied by Immergas) downstream

of the indoor unit.
