electrical conduits are suspended free of contact
with ar.y adiacent walls and be sure taiit capil­
laries are not rubbing against anything.
SERVICE ACCESS
Remove the combination top and back cover over
each compressor. Servicing can be performed from
either top or back. For rear access, allow approxi­
mately 3 ft of clear space behind unit.

CONDENSER DESCRIPTION
In the 4-condenser bundle, the lower 2 are Tower
and the upper 2 are Heat Reclaim. All are shell and
tube type with removable heads for easy tube servic­
ing. Each Tower condenser has an internal sub­
cooler designed to provide 12 F to 15 F total
liquid
subcooling at average tower water condi­
tions. The Heat Reclaim condensers do not require
subcooling,
therefore, the subcooler baffling is
removed. For further condenser data, refer to
Table 2 — Physical Data.
TOWER CONDENSER PIPING
Provide means for draining system in winter and
for maintenance.

the bottom for proper operation of the internal .
subcooler, which is in the bottom of the con­
denser (Fig. 1).
Water supply lines should be sized according to
the required flow rate for operation at design con­
ditions (not necessarily connection size). Use flexi­
ble connections to reduce vibration transmission.
A cooling tower bypass valve is usually used to
regulate the temperature of the water entering the
condensers. This may be controlled by sensing either
outdoor
air temperature or temperature of water
leaving the Heat Reclaim condensers. For further
information on Systems Controls, refer to the Engi­
neering
Guide for Reciprocating Chiller Heat
Reclaim Systems.
HEAT RECLAIM CONDENSER PIPING
Normally, the piping is for series water flow thru
the condensers. Piping to and from the condensers is
connected to the heating system of the building.
Piping for parallel water flow thru the condensers is
used only when the cooling load is constant at all
times. For further piping information, refer to the
Engineering
Guide for Reciprocating Chiller Heat
Reclaim Systems.
Figure 1 shows connections for series piping thru
the Heat Reclaim condensers.
