II. STEP 2 — MOUNT UNIT
Before mounting the 619ENF,ENQ unit on the wall with a
wall hanging bracket, consider how the unit will be
connected to the refrigerant piping. The indoor unit can be
connected in four ways. Refer to Fig. 4 for connection options.
When the piping is connected to points 1, 2 or 4, remove the
knockout either at the side or at the bottom of the unit.
The indoor units are mounted on the wall with a wall hang-
ing bracket. Position the wall hanging bracket so that it is
flush with the wall. See Fig. 5 for service clearances. See
Fig. 6 for wall bracket dimensions.
Complete the following when installing the wall hanging
bracket:
1. Before installing the wall hanging bracket to the wall
remove it from the indoor unit by pushing at the indi-
cated pressure points at the bottom of the unit.
2. Install the wall hanging bracket in a location that is
strong enough to withstand the weight of the unit.
3. Install the wall hanging bracket so that it is level.
Use a plumb line if necessary.
NOTE:
Be sure that the wall hanging bracket is level. If the
wall hanging bracket is not level water will leak from the
indoor unit.
4. Fasten the wall hanging bracket to the wall with 4 or
more screw anchors through the holes near the outer
edge of the bracket.
5. Install the wall hanging bracket flush to the wall,
and ensure the bracket does not move.
6. If the unit is removed from the wall hanging bracket
after installing it on to the wall, remove it by pushing up
on the indicated marks at the bottom of the unit body.
III. STEP 3 — COMPLETE REFRIGERANT PIPING
CONNECTIONS
When running the piping for indoor units the piping can be con-
nected as rear piping or side or bottom piping. Refer to Fig. 4.
A. Rear Piping
Route the piping behind the indoor unit so that the piping is
concealed by the unit. For rear piping installation drill a
2 1 /
2
in. diameter hole in the wall at point A or B in Fig. 6. Drill
the hole at a slope so that the outside end is lower (
1
/
4
in. to
1
/
2
in.) than the inside end to ensure optimal drainage. Refer
to Fig. 7. Pass the pipe through the hole.
B. Side or Bottom Piping
Remove the knockout in the unit and pass the piping
through the wall. The pipe should slope downward and away
from the unit to ensure optimal drainage.
C. Routing the Drain Hose and Refrigerant Piping
The drain hose and drain cap are assembled as shown in
Fig. 8 in the factory. To do right-side (
1
), right-bottom (
2
) or
right-back (
3
) piping in Fig. 4 draw the drain hose to right-
side piping direction. (It is not always necessary to exchange
the location of drain hose and drain cap.)
1. Tie together the refrigerant piping, the drain hose,
and the electrical connection wire.
2. Route the refrigerant piping in the required direc-
tion, and bend carefully avoiding pipe deformation.
3. Bind the drain hose and the electrical connection
wire together with fastening tape.
4. The drain hose should be at the bottom. See Fig. 9
and 10.
5. For left-hand piping, fit the pipes and the wiring into
the recess at the back of the unit. Fig. 4 — Indoor Unit Piping Configurations
