• make the refrigerant, electric and condensation drain connections as
specified in the “Refrigerant connections” and “Electric connections”
paragraphs;
• before removing the casing, check that the condensation drain is
working properly.

EXTERNAL UNIT INSTALLATION
Fig. 4
Secure the unit to the support plate,
making sure that the refrigerant lines, the
electric cables and the condensation drain
pipe run through the hole in the wall.
Fig. 5
The external unit must be installed outdoors, respecting the minimum
technical clearance distances in order to allow the passage of air and
the execution of any necessary maintenance operations.
Water is produced in heat pump models, during the heating mode
defrosting phase. This water needs to be collected and channelled to
the drain.
II.2.5
REFRIGERANT CONNECTIONS
IMPORTANT!
The refrigerant connections must be made by
specialist personnel in compliance with laws and
regulations in force in the country of installation.
RHOSS S.p.A. shall not be held liable for damage
to persons or property caused by incorrect
connections.
Copper pipes for cooling systems must be used for refrigerant lines,
respecting the lengths and diameters recommended in the enclosed
documents. Make sure there are no impurities or moisture inside the
pipes as this is extremely harmful for the refrigerant circuit. The
refrigerant lines must each be insulated individually with lagging of
closed-cell expanded material.
A 65 mm hole is sufficient for the passage of the pipes through the
walls.
Proceed as follows to prepare the pipes.
Cut the connection pipes at the set distance, leaving a certain safety
margin and bearing in mind the tips indicated in Fig. 8.

Make sure that the unit is
level.

Eliminate any cutting burr while keeping the pipe opening facing
downwards to prevent the ingress of debris.
Fig. 8
The consistency of the wall must be sufficient for the weight of the unit
and must not permit the transmission of noise or vibrations.
Particular care must be taken when selecting the area, so that the air
flow does not disturb the neighbours.
Cover the refrigerant lines with suitable
insulation and then insert the nozzles which
had previously been removed from the unit
connections.
