user manual
The centrifugal condensing unit may be connected to
the evaporator section by means of pre-charged
refrigeration lines (3 ton only). This greatly simpli-
fies installation and keeps installation costs low. The
copper-tube, aluminum-fin coil is equipped with low
temperature controls to assure year-round operation
to -20°F (-29°C). The condensing unit is completely
factory wired, charged and tested and is ready for
final connections.
The centrifugal fan condensing unit includes scroll
compressor, condenser coil, centrifugal blower
assembly, high-pressure switch, Lee-Temp head
pressure control.
Condensing unit has hot gas bypass standard feature
which bypasses hot gas around the compressor
directly to the suction side of the compressor to pro-
vide capacity control and reduce compressor cycling.
System includes liquid injection valve to maintain
proper suction superheat.
Unit must be mounted indoors. Duct flanges are pro-
vided.
The air cooled condensing unit can be mounted on
the roof or a ground level site. The condensing unit
housing is manufactured of galvanized steel with a
powder coat finish. The copper-tube, aluminum-fin
coil is equipped with low temperature controls to
assure year-round operation to -30°F (-34.4°C). The
condensing unit is completely factory wired, charged
and tested and is ready for final connections. (See
illustration below)
The standard prop fan condensing unit includes
scroll compressor, prop fan, high head pressure
switch, hot gas bypass and Lee-temp head pressure
control (for operation down to -30°F (-39°C) ambient.)
This unit is available in these optional configura-
tions:
• 105°F (40°C) ambient for high ambient condi-
tions.
• 95°F (35°C) ambient Quiet-Line for low noise
level conditions below 58 dBa.
Factory installed non-fused disconnect switch
allows unit to be turned off for maintenance. Discon-
nect switch is available on indoor condensing units
only.
(3 ton only): Consists of one pre-charged liquid line
and one pre-charged insulated suction line of soft
copper tubing. Each line has one male quick-connect
coupling and one female quick-connect coupling with
an access valve connection.
Available in 15 ft. (4.6m) and 30 ft. (9.1m) lengths for
interconnection of remote located condenser module.
Maximum recommended distance between evapora-
tor and condenser modules with pre-charged line sets
is 45 ft. (13.7m). For longer runs, use sweat adapter
kit.
(3 ton only): Contains two suction and two liquid line
compatible fittings that allow field-supplied intercon-
necting refrigerant lines to be used.
