Make Flexible Hose Connections to the
Supply and Return Valves From Riser Stub-
Outs
1 . Using the specified supply and return hoses make supply
and return hose connections to the riser stub-outs valve
connections (Figure 31).
2 . Attach one end of the JIC swivel hose end to the male JIC
connection on the supply and return stub out valves. Using
two crescent wrenches, one to hold the valve and the
second on the hose end, tighten the connections.

Flexible Hose
Note: To complete the flexible hose connections to the
chassis, only partially install the chassis into the cabinet
as shown in Figure 34.

Important When Handling Chassis

Note: If using a hand truck to move chassis, tip the chassis
forward or back only, pivoting on the ends of the
chassis rails. Tipping and pivoting the chassis side-to
side on the long edge of the rails will damage the rails
and the rubber vibration isolators.
!
CAUTION
To avoid personal injury, protective gloves should be used
while moving and lifting the unit chassis.

Installing Unit Chassis

2-Position
1 . Install the chassis by sliding it into the cabinet opening until
Hand Valve
the chassis support rails sit on the cabinet rails. Slide the
chassis into the cabinet until there is approximately a 10"
space between the chassis coil and the cabinet. This will
allow adequate clearance to connect the flexible hoses to
the chassis coil. For safety, place a 6" high block under the
chassis rails to support the chassis as shown in
Figure 34: Slide chassis partially into the unit cabinet
