Operating Manual SunCool for SUNTEST
®
CPS+
The liquefier unit can be installed separately on the floor or
in combination with the SUNTEST
®
CPS+ on a workbench
or sub frame with shelves. If the equipment is placed on a
device, no other equipment which is sensitive to vibrations
should be placed on this surface. The compressor of the
liquefier unit vibrates during liquefaction of the coolant
and could have a damaging effect on equipment which
is sensitive to vibrations.
NOTE – condensation
Colder indoor temperatures may result in small amounts of
condensation on the liquefier unit when the chiller starts.
Please bare in mind when choosing the installation site that
dripping condensation can cause damage. The SUNTEST
CPS+ and the evaporator trough should, therefore, always
be placed on a surface above the liquefier unit.
Installing the liquefier unit (Fig. 6.3)
1. Install the SUNTEST CPS+ instrument

2. Install the liquefier unit

of the chiller, taking into
account that the length of the hose/cable connections
4
to the evaporator unit
1
is 2.5 m. Assure proper
distances are kept from adjacent surfaces as noted in
Figure 3. Align the liquefier unit horizontally and check
the stability of the unit.
3. Remove the filter mat
3
from the air inlet aperture
on the SUNTEST instrument. Position the evaporator
unit of the chiller close to the air inlet aperture of the
weathering instrument. The instrument connection
requires no other connecting elements.
4. Lay the hose connections
4
between the units so that
a bending radius of at least 20 cm is kept at bends.
5. Make sure that the hoses or connecting cables are not
exposed to tensile or tractive forces.
NOTE – return coolant
If the liquefier unit was tilted or turned upside down during
transport or installation, it must remain in its correct posi-
tion for two hours prior to starting the cooler to allow the
coolant to collect completely in the liquefier unit.
