Figure 4 - Gasket Material
An insulation piece is factory installed between the module
sections to seal any possible air leakage where the water
piping passes through the cabinets Cut a hole in the
insulation to feed both the inlet and outlet water piping
through
Install the pipes and attach to the existing unit piping using
the grooved end couplings Hand tighten the bolts on
the grooved end couplings until all interconnecting piping
connections are made Then, fully tighten all the bolts as
necessary
The interconnecting piping needs to be wrapped to minimize
any condensate forming on the piping The same gasket
material used to seal between the cabinet sections can be
used
Resealable Refrigerant Fittings
All units are shipped from the factory with a full factory
refrigerant charge The resealable refrigerant fittings must
be connected and properly tightened to facilitate refrigerant
flow between the evaporator and compressor / condensing
section
For shipping purposes the refrigerant fittings are held in place
to the cabinet using vinyl coated hangers and a mounting
bracket These are to be removed before the refrigerant
fittings are connected
1�
On the refrigerant resealable fittings, apply a few drops
(5 to 6 droplets are recommended) of refrigerant oil to
the male coupling halves before starting the assembly
(Ref to Figure 6)
2�
Align each resealable fitting and hand thread the female
fitting onto the male fitting (Ref to Figure 6) Continue
to hand thread until resistance is observed
3�
Once slight resistance is evident, continue to tighten
the fittings using the appropriate size wrenches listed in
Table 1 Please note that it is important to support the
male side of the fitting with a wrench when tightening
the female side with a wrench

If the resealable fittings still feel loose, tighten a bit
more as required
