Step By Step Guide To High ESP Duct Unit Installation
2.1
Step 2.1
Determine and mark the position of where the High ESP
Duct unit is to be installed. Install the hardware necessary
to mount the threaded rods. Always select a location
strong enough to support the indoor High ESP Duct unit.
2.2
Step 2.2
Install the threaded rods to the hardware attached to the
structure.
2.3
Step 2.3
Lift the High ESP Duct unit and position the threaded rods into
the 4 mounting clips, one located on each corner of the unit.
2.4
Step 2.4
Using a level, adjust the nuts on the threaded rods to obtain
level readings both side to side and front to back on the
High ESP Duct unit.
2.5
Step 2.5 - 2.5A
Prior to routing the refrigerant lines to the unit, install the
supplied are nuts onto the refrigerant lines. Using a aring
tool, flare the refrigerant lines. Remove the caps attached
to the ends of the refrigerant line connections at the High
ESP Duct unit. Holding charge should leak out. Attach the
refrigerant lines to the air handler.
Using a torque wrench, torque the ttings to the proper
specications. (See Outdoor Unit Section for are torque
settings.)
2.6
Step 2.6
Connect the grey flexible drain hose supplied with the High
ESP Duct unit to the condensate pump discharge pipe of
the High ESP Duct unit. Tighten the clamp securely. Using
3/4 “ PVC, connect the flexible hose to the building’s
condensate drain system.
2.7
Steps 2.7 - 2.7A - 2.7B
Route the 14AWG stranded 4 conductor power/
communication cable and the wired remote cable to the air
handler. Use reducing washers and appropriate connector
to attach the power/communication cable to the unit. The
wired remote cable will enter the unit through a rubber
grommet. The 4 conductor cable connects to the terminal
block at terminals 1, 2, 3, and ground. The wired remote
cable connects to the air handler main board at connector
CN1. Re-install electrical box cover.
The unit is now ready for connection to the ductwork.
The return air duct can be congured as either a rear side
inlet or bottom side inlet.
