Installation and Maintenance Manual

Installation
16 WSHP-SVX10B-EN
Chassis Installation
(a) Not all units will include shipping bolts.
4. Connect water coil pipe to the system riser with a
flexible steel hose assembly.
5. Verify that the shut-off/balancing valve in the return
line/supply line are closed.
6. Place shut-off valves in appropriate location (see
sticker on the equipment for best placement
recommendation) to allow chassis to slide easily in/out
of unit cabinet.
7. Flush system. See “Cleaning and Flushing the Water
Loop,” p. 16,” for flushing instructions.
8. Open the unit water valves and check piping for leaks.
9. Connect electrical to unit chassis via the quick connect
mating plugs.
Note: Four plugs are included (motor, optional
condensate overflow, power and thermostat).
11. Verify unit’s air filter has shipped with the cabinet.
12. Install cabinet’s front cover to the hinged door.
Important: Ensure the gasket material creates a
positive seal around the entire coil to avoid
coil bypass. If a field supplied door is used,
ensure the front cover is attached to the
building structure and not the unit cabinet.
Supply Grille Installation
See Table 5, p. 16 for supply air dimensions.
1. Install the supply grille(s) into the cabinet discharge
opening. Ensure there are no air gaps between the
cabinet supply air and the grille.This helps prevent
recirculation of supply air into the return air opening
behind the drywall.
2. Secure grille(s) into the drywall via two screws.
Cleaning and Flushing the Water Loop
After the piping system is complete, the flexible hose
connectors should be doubled back to complete the water
circuit external to the unit (avoiding trash settle-out in the
condenser). An extra pipe may be necessary to connect
the hose kits. See “Using Antifreeze,” p. 17 for antifreeze/
water mixture by volume.
1. Water circulation system should be filled with clean
water using the water make up connections.
Note: Air vents should be opened during filling.
2. With the air vents closed, start the circulating pump
and then crack the air vents to bleed off the trapped air,
assuring circulation through all components of the
system.
Note: Make up water must be available to the system to
replace the volume formerly occupied by the air
that is bled off.
Note: System water pressure needs to be relieved prior to
opening system.
3. With the air vented and the water circulating, the entire
system should be checked for leaks with repairs made
as required.
4. Operate the supplementary heat system making
checks per manufacturer’s instructions. During this
operation, visual checks should be made for leaks that
Figure 11. Shipping bolts (see arrows)
1. Remove three 18-inch
bolts on the chassis
and discard.
2. Rotate the triangular
metal plate to cover the
bolt holes in the
chassis. Secure with
two sheet metal
screws.
Figure 12. Bracket removal for deluxe sound package
3. Remove oneshipping
bracket (one on each
side) attached to the
chassis slide rails and
discard.
Note: Remove this
bracket only if the
deluxe sound
package design is
selected.

10. Slide chassis into the cabinet.
Center the chassis left to right to
minimize sound transmission.
