5. Tubing may be run through the knockouts located on
the bottom left rear (room side) of the unit, as well
through knockouts in the back of the unit.
6. Consider future servicing of the unit when determin-
ing mounting location. All FHP service is performed
by removing the front (room side) panels.
OPTIONAL FRESH AIR
Units with a wall box (field supplied only for fresh air)
must be checked to ensure the unit is level and the floor of
the wall box is pitched down and away from the unit. The
drip edge of the wall box must clear the edge of the finished
outside wall (See
Figure 7
– Wall Box Positioning). EMI
recommends that all electrical, refrigerant, and condensate
lines are routed through the wall or floor to the correct lo-
cations to use the knockouts before the unit is mounted in
place.
REFRIGERANT PIPING
The FHP is equipped with a Flo-Rater/Piston Expan-
sion Device. Connections are male flare type
(flare nuts
not included).
The suction line (large) must be insulated the entire
length with closed cell, foam tube insulation. Do not insulate
the liquid line (small). Connect the outdoor unit according
to the instructions supplied with unit.
All horizontal piping runs must be level and without
dips to trap the oil.

Figure 7
If a fresh air connection is necessary for this FHP/FCP
installation, please note the following:
• All ducts, collars, and dampers are field supplied. The
back side has a 4” knockout for a fresh air duct.
• Block the opening during installation to prevent foreign
objects from getting into the unit.
• The duct should be installed with a slight downward
pitch away from the unit to prevent moisture from en-
tering the unit.
Secure the unit to the wall using lag screws or other
appropriate anchor devices. Then connect all wiring and
tubing connections.
