INTRODUCTION

Models FEM4P, FSM4P, and FSU4P are for R-410A refrigerant.

Models FEM4P and FSM4P are designed for maximum

flexibility and can be used for upflow, horizontal left or

right, and downflow applications (accessory kit required

for downflow).

Model FSU4P is designed for upflow installation, and can be field modified for downflow applications (accessory kit required).

LOCATION

Select the best position which suits the installation site conditions. The location should provide adequate structural support, space in the front of the unit for service

access, clearance for return air and supply duct connections, space for refrigerant piping connections and condensate drain line connections. If heaters are being

installed make sure adequate clearance is maintained

from supply duct work. See Clearances in Figure 1 and

Figure 2. If the unit is located in an area of high humidity, nuisance

sweating of casing may occur. On these installations a wrap of 2" (51mm) fiberglass insulation with a vapor barrier is

recommended.

FEM4P models are available for system sizes 1-1/2 - 4

tons (18,000 - 48,000 BTUH) nominal cooling capacity.

FEM4P uses a refrigerant piston metering device with an ECM integral electronically commutated motor for

efficiency. FSM4P and FSU4P models are available for system

sizes 1-1/2 - 4 tons (18,000 - 48,000 BTUH) nominal

cooling capacity. FSM4P and FSU4P use a refrigerant piston metering device with 2-speed PSC (permanent

split capacitor) motors. All models require a field supplied air filter. Factory

approved electric heater packages are available in sizes 5kW through 30kW. See Product Specification literature for available accessory kits

NOTE: Internal filter can be accessed from separate filter

door. If the filter can NOT be easily accessed, a remote filter is recommended. Refer to ACCA Manual D for

remote filter sizing.

FIRE HAZARD Failure to maintain proper clearances could result in

personal injury, death, and/or property damage. When heaters are installed, maintain clearances from

combustible materials as specified on unit rating plate. Do not use plastic lined or combustible flexible

ducting within 36 inches of the supply end of the fan coil.

HEATER PACKAG ES

Factory approved, field installed, UL listed heater packages are available from the equipment supplier. See unit rating plate for a list of factory approved heaters.

POSITION UNIT

Unit can stand or lie on floor, or hang from ceiling or wall. Allow space for wiring, piping, and servicing unit.

PROPERTY DAMAGE HAZARD Failure to follow this caution may result in proper-

ty damage A field fabricated auxiliary drain pan, with a sepa-

rate drain is REQUIRED for all installations over a

finished living space or in any area that may be damaged by overflow from a restricted main drain

pan. In some localities, local codes require an aux- iliary drain pan for ANY horizontal installation.

UPFLOW/_

Heaters that are not factory approved could cause damage which would not be covered under the equipment warranty.

A. UPFLOW INSTALLATION

If return air is to be ducted through a floor, set unit on floor over opening and use 1/8 to 1/4 inch thick (3 to 6 mm

thick) fireproof resilient gasket between duct, unit, and floor.

Side return is a field option on slope coil models. Cut opening per dimensions shown in Figure 3. A

field-supplied bottom closure is required.

B.DOWNFLOWINSTALLATION

PRODUCT OR PROPERTY DAMAGE HAZARD Failure to follow this caution may result in product

or property damage The conversion of the fan coil to downflow re-

quires special procedures for the condensate drains on both A-coil and Slope-coil units. The vertical drains have an overflow hole between the

primary and secondary drain holes. This hole is plugged for all applications except downflow, and

must be used for downflow. Failure to follow instructions could result in per-

sonal injury or product and property damage.

In this application, field conversion of the evaporator coil is required using accessory Downflow Kit along with an

accessory Base Kit. Set unit on floor over opening and use 1/8" to 1/4" thick fireproof resilient gasket between

duct, unit, and floor. Refer to installation instructions packaged with accessory kit. See Product Specification literature for kit part numbers.

During the conversion process, removed the plastic cap covering the vertical drains only and discard.

Remove the plug from the overflow hole and discard.

At completion of the downflow installation, caulk around the vertical pan fitting to door joint to retain low air leak

performance of the unit. NOTE: Gasket kit number (EBACO1GSK) is also

required for all downflow applications to maintain low air leak/low sweat performance.

C. HORIZONTAL INSTALLATION

Unit must NOT be installed with access panels facing up or down. Access panels must only face to the side.

FEM4P and FSM4P models are factory built for horizontal left installation (refer to Figure 4 and Figure 5).

They can be field converted to horizontal right (accessory

Gasket Kit required, see Product Specification literature

for part number). Refer to Figure 6 and Figure 7.

NOTE: When suspending unit from ceiling, dimples in casing indicate suitable location of screws for mounting metal support straps (refer to Figure 4).

NOTE: For optimum condensate drainage performance in horizontal installations, unit should be leveled along its

length and width.
