SAFETY CONSIDERATIONS

Improper installation, adjustment, alteration, service, maintenance,
or use can cause explosion, fire, electrical shock or other conditions
which may cause death, personal injury or property damage.
Consult a qualified installer, service agency, or your distributor or
branch for information or assistance. The qualified installer or
agency must use factory--authorized kits or accessories when
modifying this product. Refer to the individual instructions
packaged with the kits or accessories when installing.

Follow all safety codes. Wear safety glasses, protective clothing
and work gloves. Use quenching cloths for brazing operations.
Have fire extinguisher available. Read these instructions
thoroughly and follow all warnings or cautions attached to the unit.
Consult local building codes and the current editions of the
National Electrical Codes (NEC) NFPA 70.

In Canada, refer to the current editions of the Canadian Electrical
Code CSA C22.1.

Recognize safety information. This is the safety--alert symbol
When you see this symbol on the unit and in instructions or

manuals, be alert to the potential for personal injury.

Understand the signal words DANGER, WARNING and

CAUTION. These words are used with the safety--alert symbol.
DANGER identifies the most serious hazards which will result in

severe personal injury or death. WARNING signifies hazards
which could result in personal injury or death. CAUTION is used
to identify unsafe practices, which may result in minor personal
injury or product and property damage. NOTE is used to highlight
suggestions which will result in enhanced installation, reliability, or
operation.

WARNING

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal injury
or death.

Before installing or servicing system, always turn off main
power to system. There may be more than one disconnect
switch. Turn off accessory heater power if applicable. Lock out
and tag disconnect switch with a suitable warning label.

!

WARNING

EXPLOSION HAZARD

Failure to follow this warning could
result in death, serious personal injury,
and/or property damage.

Never use air or gases containing
oxygen for leak testing or operating
refrigerant compressors. Pressurized
mixtures of air or gases containing
oxygen can lead to an explosion.

!

CAUTION

PERSONAL INJURY HAZARD

Failure to follow this caution may result in personal injury.

This coil contains Nitrogen precharge of up to 15 PSI. Release
of this pressure through the center of the rubber plugs is
required before removing the plugs.

!

.

CUT HAZARD

Failure to follow this caution may result in personal injury.

Sheet metal parts may have sharp edges or burrs. Use care and
wear appropriate protective clothing and gloves when
handling parts.

IMPORTANT: Nitrogen can leak out through the hole that the
needle pierced in the plugs. This does not indicate a leaking coil
nor warrant return of the coil.

CAUTION

INTRODUCTION

Use this instruction manual to install CAPVP indoor coil on
multipoise furnaces. (See Fig. 1.) The CAPVP coil is enclosed in a
casing.

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 upflow 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.

See Table 1 for dimensions. Note instructions for placement of coil
casing on furnace.

Downflow CAPVP 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.)

Upflow CAPVP Coil 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.

Fig. 3 -- Downflow Installation With Coil Rotated 90_

1. Set cased coil on supply duct opening.

2. Place field fabricated 3” (76 mm) adapter on coil casing.
Adapter should be tapered to fit coil/furnace combination
when one of them is larger than the other.

3. Set furnace on adapter.

NOTE: In downflow installation with a 4--way multipoise
furnace, break off perforated duct flanges on furnace. See furnace
installation instructions.

CONNECT REFRIGERANT PIPING

Use accessory tubing package or field--supplied tubing of
refrigerant grade, see Product Data information for ordering.
Suction tube must be insulated. Do not use damaged, dirty, or
contaminated tubing because it may plug refrigerant flow--control
device. AL WAYS evacuate the coil and field--supplied tubing
before opening outdoor unit service valves.
