6.6 Outdoor installation
of the liquefier unit
NOTE – installation work
The outdoor installation of the liquefier unit, the position-
ing of supply and return cables for the coolant and the
positioning of the power and connecting cables should
only be performed by authorized and qualified cooling
and air conditioning technicians and electricians!
WARNING – malfunction!
When installing outdoors, the chiller connec-
tion must be protected from rain and splash-
ing water to avoid malfunctions or electrical
shocks!
Assembly position:
In outdoor installation, the liquefier unit should be mounted
in a place protected from the sun and rain. For protection
against collecting water or snow, the mounting position
should be approx. 20 to 30 cm above the ground or the
floor or the liquefier unit should be placed on an appro-
priately high base. The safety distances (chap. 3.7) from
adjacent surfaces should be maintained on all sides.
Condensation forms when operating the liquefier unit at
cold outdoor temperatures. Therefore, an appropriate as-
sembly position must be utilized in order to avoid dripping
condensation causing damage.
The difference in height between the assembly position of
the liquefier unit and the installation site of the evaporator
unit/SUNTEST instrument should not exceed 5 m. See
section 6.4 for installation of these units.
NOTE – winter operation
The liquefier unit is equipped with a winter control; no
additional condensation pressure regulation is required
for outdoor installation.
Pipe material (Fig. 6.4):
For outdoor installation, the supply and return pipes (see
fig. 6.4
) must be installed using flexible copper pipe de-
signed for the transfer of refrigerant. The pipe should not
exceed a maximum length of 15 m. Under no circum-
stances should the enclosed standard hose connections
be used. Supply and return pipes should be installed with
as few bends as possible; the inside diameter of the pipes
must not be compromised by crushed pipe material when
laying bends. Then bending radius must be at least 20 cm.
