INSTALLATION

Procedure 1 -- Inspect Equipment

File claim with shipper if equipment is damaged or incomplete.

Procedure 2 -- Select Installation

For upflow application follow:

A. Upflow CAPMP/CARMP Coil Installation.

See Table 1 for dimensions. Note instructions for placement of coil

casing on furnace.

For downflow application follow-:

B. Downflow CAPMP/CARMP Coil Installation.

For horizontal application follow-:

C. Horizontal CAPMP/CARMP ('oil Installation.

Procedure 3 -- Installation of Evaporator Coils

A. Upflow CAPMP/CARMP Cased ('oil Installation

The cased coil is designed to fit furnaces of the same width.

1. Set coil in place on upflow furnace discharge air opening.

2. Ensure coil is level for proper condensate drainage. Do not

tip coil toward condensate drain. Coil casing need not be

fastened or screwed to furnace.

3. When installing wider coil on narrow furnace, create field

fabricated adapter. (See Fig. 2.)

4. When installing narrow coil on wide furnace, create field

fabricated adapter. (See Fig. 2.)

NOTE: On up flow installations where the indoor coil is placed in

an unconditioned space, a 6" (152 mm) wide piece of insulation

should be applied and wrapped around the outside of coil casing

and supply duct contact point.

B. Downflow CAPMP/CARMP Cased Coil Installation

IMPORTANT: Installing "A" coils rotated 90 ° from the front of

the furnace in downflow applications can cause water blow off or

coil freeze up. This is due to the concentration of air on one coil

slab or lack of air on the opposite coil slab. If the airflow is high

due to ductwork or other causes, and there is a chance for water

blow off. it is recommended that a 3" (76 mm) field-supplied

adapter be placed between the coil and the furnace to allow the air

to distribute evenly to both coil slabs. (See Fig. 3.)

Procedure 5-- Connect Refrigerant, Liquid, and

Suction Lines

For matched and mismatched systems, use line sizes recommended

in outdoor unit Installation Instructions.

The coil can be connected to outdoor units using accessory tubing

packages or field-supplied tubing of refrigerant grade. Always

evacuate tubing and reclaim refrigerant when making connections

or flaring tubing. Leak check connections before insulating entire

suction line.

See Table 1 for coil connection tube size.

1. Remove cabinet door. Remove tubing plate with rubber

grommets and slide plate with grommets onto the

refrigerant lines (field line-set), away from braze joints.

2. Remove rubber plugs from coil stubs using a pulling and

twisting motion. Hold coil stubs steady to avoid bending or

distorting.

3. Wrap TXV and nearby tubing with a heat-sinking material

such as a wet cloth.

4. Fit refrigerant lines into coil stubs. Wrap a heat sinking

material such as a wet cloth behind braze joints.

5. Braze using a Sil-Fos or Phos-copper alloy.

6. After brazing, allow joints to cool. Slide tubing plate with

rubber grommets over joints. Position tubing at center of

each grommet to ensure an air seal around the tube.

UNIT DAMAGE HAZARD

Failure to follow this caution may result in product damage.

To avoid valve damage to the refrigerant control device while I

brazing, valves must be wrapped with a heat-sinking material

such as a wet cloth.

REFRIGERANT METERING DEVICE

CAPM Models:

These Coils have a factory installed hard shut-off TXV designed

only for use with R-410A refrigerant. Use only with outdoor units

designed for R-410A.

CARM Models:

These Coils have a factory installed hard shut-off TXV designed

only for use with R-22 refrigerant. Use only with outdoor units

designed for R-22.

NOTE: All TXV'S have preset superheat settings and are field

non-adjustable.

Procedure 6 -- Make Condensate Line

Connection

The coil is designed to dispose of accumulated water through

built-in condensate drain fitting. Two 3/4" female threaded pipe

connections are provide in each coil.

Install a trap in condensate line of coil, as close to the coil as

possible. Make trap at least 3" (76 ram) deep and not higher than

bottom of unit condensate drain opening. (See Fig. 8.) Pitch

condensate line to open drain or sump.

NOTE: The unit is shipped from the factory with the horizontal

drain connections capped as for vertical installations. For

horizontal installations, remove the caps and place them on the

vertical drain connections to keep an airtight installation.

NOTE: If unit is located in or above a living space where damage

may result from condensate overflow, a field-supplied, external

condensate pan should be installed under the entire unit, and a

secondary condensate line (with appropriate trap) should be run

from the unit into the pan. Any condensate in this external

condensate pan should be drained to a noticeable place. As an

alternative to using an external condensate pan, some localities

may allow the running of a separate 3/4" (19 mm) condensate line

(with appropriate trap) per local code to a place where the

condensate will be noticeable. The owner of the structure must be

informed that when condensate flows from secondary drain or

external condensate pan, the unit requires servicing or water

damage will occur.

NOTE: To avoid drainage problems, test the primary drain line by

slowly pouring water into the pan. Check piping for leaks and

proper condensate drainage. Using the secondary drain as

explained in the previous note provides future protection against

overflow due to a clogged primary drain.

NOTE: In applications where return air humidity levels stay at

70% or above for a prolonged period of time, condensation can

form on the bottom of pan and drip.

UNIT DAMAGE HAZARD

Failure to follow this caution may result in product damage.

DO NOT BURY MORE THAN 36" (914 mm) OF

REFRIGERANT TUBING IN GROUND. If any section of

tubing is buried, there must be a 6" (152 mm) vertical rise to the

valve connections on the outdoor unit. If more than the

recommended length is buried, refrigerant may migrate to cooler

buried section during extended periods of unit shutdown,

causing refrigerant slugging and possible compressor damage at

start-up.
