The Ductless Split System of Choice
MOUNTING PREPARATION
The FHP/FCP is designed to sit directly on a finished
floor, flush against a wall. Moldings or baseboard must be
cut to allow the unit to be mounted flush against the wall.
Units being installed without a wall box should be test
fit for wiring and tubing positions. Place the unit against the
wall with the front panels removed. Mark the connection
locations on the wall. Shim the unit, if necessary, for square
floor to wall positioning.
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 1
– Wall Box Positioning). EMI
recommends that all electrical, refrigerant, and condensate
lines are routed through the wall or floor to the correct loca-
tions to use the knockouts before the unit is mounted in
place.
OPEN FRESH AIR UNIT PREPARATION
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 enter-
ing the unit.
Secure the unit to the wall using lag screws or other
appropriate anchor devices. Then connect all wiring and
tubing connections.
REFRIGERANT PIPING
The FHP is equipped with a Flo-Rater/Piston Expan-
sion Device. Connections are male flare type.
The suction line (large) must be insulated the entire
length with closed cell, foam tube insulation. Do not insu-
late the liquid line (small). Connect the outdoor unit accord-
ing to the instructions supplied with unit.
All horizontal piping runs must be level and without dips
to trap the oil.

ITEMS FOR CONSIDERATION
• EMI’s FHP evaporator requires 24V power for control
operation. When matching the FHP with a non-EMI
condenser, a 24V transformer may need to be added
to the condenser.
• Ensure that the FHP interconnect tubing is within a
maximum allowable length of 100’ including, a maxi-
mum 35’ lift.
