(6) Pull the power wiring from the conduit into the unit. Connect the ground wiring to the screw for ground
wiring connection first. Then connect the power wiring and communication cable terminals to the
terminal blocks. Allow extra length for all wiring inside the electrical box. Secure the wiring with the
attached cable band.
(7) Tighten the conduit locknut after the power wiring connection is made.
(8) Close the electrical box cover. Reattach the lower right corner cover, front panel and flat panel into
position. When mounting the front panel, be careful that it does not come into contact with the air outlet
louver. Paying attention to both sides of the panel, secure catch-fittings (at front locations) on the upper
side of the unit into the holes on the panel. Then insert the lower side of the panel (both ends) to secure
these catch-fittings.
NOTE:
Make sure that there are no gaps or overlapping between front panel and left side of the condensate
pan. If any gap is present, escaping air combined with condensation can leak out and spill out onto unit
surfaces.
(9) Tighten three (3) screws and attach three (3) screw caps. Then install the air filter.
(10) Insert the arm shafts on both sides of the flat panel into the corresponding holes on the unit body, along
the front panel guides. After the flat panel is attached, close the flat panel.
