4. Refrigerant Line Installation
A. Remove the knockout from the desired side of the
unit that the line set will be routed from. The lines
from the unit can be routed either left or right, left
back or right back (Fig. 11).
B. Loosely run the line set connections from the in-
door unit through the hole in the wall (Fig. 8).
C. Hang the unit onto the top flanges of the wall
bracket. Ensure the unit is properly seated. (Fig.
12)
D. Keep the unit away from the wall to prevent the
line set from being kinked or crushed, use a piece
of styrofoam as a spacer between the back of the
unit and the wall. (Fig. 13)
E. Feed the condensate drain line and refrigerant line
set through the hole such that the unit can sit flush
against the wall then remove the spacer (Fig. 8).
F. Push the bottom of the unit up and onto the lower
flanges of the wall bracket. Ensure that unit is
properly sealed.
G. Be sure that the overall installation of the indoor
unit and installation plate are flush against the wall
and level.
5. Piping and insulating
A. Bundle the tubing, connecting cable, and drain hose
with tape or wire ties as shown in (Fig.14).
B. Be sure to arrange the drain line such that it is at
the lowest point within the bundle as they exit the
unit and hole in the wall to the outdoors. (Fig. 14)
C. Because the condensed water from rear of the
indoor unit is gathered in the ponding. Do not put
anything else in this area.
E. Insulate the liquid line and suction lines separately.
