Hose Kit and Chassis Installation, Cont’d.
Step 3: Attach AHH or AHU hoses to the Chassis. Check
the swivel ends of the hoses (Figure 21). Washers must
be in the hose for water tight connection. Slide the
chassis part way into the cabinet. Match the WATER IN
(supply) hose to the WATER IN tube on the chassis and
the WATER OUT (Return) hose to the WATER OUT tube.
Position hose toward chassis, use gentle loop- see bend
radii Table 7. Hand tighten hose.
Figure 21
Washers
Do not bend hoses at less than the minimum bend radius
for the hose selected. Less than the minimum bend radius
may cause the hose to collapse, which reduces water flow
rate. Install an angle adapter to avoid sharp bends in the
hose when the radius falls below the required minimum.
Table 7: Hose Minimum Bend Radii
Hose Diameter
Minimum Bend Radii
1/2" (12.7)
2.5 (63.5)
3/4" (19.1)
4.5 (114.3)
1" (25.4)
5.5 (139.7)
CAUTION!
Corrosive system water requires corrosion
resistant fittings and hoses, and may require water treatment.

WARNING!
Under no circumstances should any part of the
hose itself be gripped or twisted by hand, pliers, channel
locks or any other tool. Leakage or bursting may occur!
Always use a back-up wrench when tightening the hose.
Step 4:
Chassis Installation - Check condensate pan is
free and on 4 rubber grommets
.
Install the Chassis as follows:
1. Slide Chassis fully into cabinet. Check hose for kinks,
do not allow less than minimum bend radius (see
table 7), pull chassis partway out, loosen hose and
reposition hose if needed, re-tighten.
2. Verify that both the shut-off valves are closed. See
Figure 20. (handle horizontal)
3. Verify riser stack has been pressure tested, and all
leaks have been repaired.
4.
Flush system following the procedure in Preparation
for Start-up Section of this manual.
5.
When the system is clean and flushed, open both
water shut off valves and check piping for leaks.
Repair all leaks before continuing.
6. Complete electrical connections between cabinet and
chassis. Connect wire harnesses hanging down from
under side of control box to chassis connections. (See
Figure22). Check that Molex connectors are snapped
together, pull gently on connector - do not pull on
wires.

IMPORTANT!
After the system has been filled and system
pump is started, all connections should be rechecked for
water leaks. ClimateMaster WILL NOT be responsible or
liable for damage caused by water leaks at any field water
connections!
