DESCRIPTION

 

The FHP 09-30 and 36-48 is available in two cabinet 

sizes with nine capacities in Cooling Only or Heat Pump 

(depending on condenser match).

 

FHP units are equipped with a unit mounted control 

that allows the unit to operate in either straight cool or heat 

pump mode.  The unit is configured by changing dip switch 

settings prior to installation. FHP units are compatable with 

any AmericaSeries outdoor unit.

 

 

FHP units are shipped from the factory 

set in cooling 

only 

mode and will need to be reset for heat pump applica-

tions.

 

The FCP is a Chilled Water model with electric or hot 

water heating options and is compatible with any chilled 

water source of matching capacity.

 

A unit mounted, electronic, digital control is standard 

and an optional infrared handheld remote control is avail-

able.  Fresh air knockouts and anti-short cycle protection 

are standard features on all FCP/FHP units

NOTE: 

If equipped with hydronic heat, the FHP will 

only operate as a single-stage heating unit and not 

as a two-stage heating unit.

OPTIONAL CONTROLS & COMPONENTS

• Fan-Induced fresh air (FHP only)

See page 4 in Common Section for 

complet list of Optional Controls/Components

 MOUNTING PREPERATION

1. Check equipment for damage before mounting.

2. Determine the best location for mounting the unit for 

optimum air circulation.

3. Locate the indoor and outdoor units as close together 

as possible. (See outdoor unit requirements.)

UNIT MOUNTING

 

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 that are 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 connec-

tion locations on the wall.  Shim the unit, if necessary, for 

square floor to wall positioning.

 4. Determine the following:

• Power supply wire routing

• Interconnect refrigerant piping routing

• Chilled water and condensate piping routing (FCP)

• Low voltage control interconnect wiring

• Fresh air ducting (if required)

NOTE: 

 FHP 42 contains Kit# 550-121 that includes 

a .073” I.D. orifice.  The existing factory installed 

.078” orifice must be replaced with the one sup-

piled in the kit when matching an Air Handler with 

a 36,000 Btuh Condensing Unit.  (See the instruc-

tions attached to Kit# 550-121 for proper conver-

sion procedure.)

FLOOR MODEL AIR HANDLER 

(FCP/FHP)

NOTE: 

The FHP utilizes a molded plastic top.  DO 

NOT sit or stand on it as you may damage the unit.

ITEMS FOR CONSIDERATION

• EMI’s FHP evaporator requires 24V power for control 

operation.  

(As of 12/01/04 a transformer is supplied 

in the indoor unit).

• Ensure that the FHP interconnect tubing is within 

a  maximum  allowable  length  of  100’  including,  a 

maximum 35’ lift.

• Liquid line filter dryer.
