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 the system using the cleaning and flushing the water
loop 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).
10. Slide chassis into the cabinet. Center the chassis left to
right to minimize sound transmission.
Figure 15. Install chassis centered
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.

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
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.
Notes:
•
Make up water must be available to the system to replace
the volume formerly occupied by the air that is bled off.
•
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 may have
occurred due to increased heat. Repair as required.
5. Open the system at the lowest point for the initial blow
down (making sure the make up water is equal to the water
being dumped). Continue blow down until the water
leaving the drain runs clear, but not less than 2 hours.
6. Shut down pumps and supplementary heat system.
Reconnect the hoses placing the water-to-refrigerant heat
exchanger in the water circulating system.
