Additional Location Requirements
for Remote Evaporator Only
The remote evaporator must be
installed indoors, unless:
– ambient temperatures are always
above 32 F.
– the system circulating liquid is a non-
freezing glycol-type solution, selected
for the prevailing ambient
temperatures.
– the evaporator is protected from
freezing by properly installed and
applied insulation and heat tape.
Caution: To prevent internal
damage due to freezing, do not
install the outdoor unit without
adequate freeze protection.
The remote evaporator should be
mounted on a base of suitable strength
to support the operating weight.
Remote evaporator weights and
mounting locations are shown in
Figure 13.
The remote evaporator must be level
when installed. Be sure to allow
adequate clearance for water and
refrigerant piping connections,
performance of service procedures,
reading of gauges and thermometers,
and operation of valves. Space must be
allowed at one end of the evaporator to
pull tubes, if required.
Drainage
Provide a large capacity drain for water
vessel drain-down during shutdown or
repair. The evaporator is provided with
a drain connection. Refer to
“Evaporator Drain”. All local and
national codes apply. The vent on the
top of the evaporator is provided to
prevent a vacuum by allowing air into
the evaporator for complete drainage.
