Suction tube must be insulated. Do not use damaged, dirty, or

contaminated tubing because it may plug refrigerant flow

control

device. ALWAYS evacuate the coil and field

supplied tubing

before opening outdoor unit service valves.

CONNECT REFRIGERANT LIQUID AND

SUCTION LINES

For matched and mismatched systems, use line sizes recommended

in outdoor unit Installation Instructions.

UNIT OR PROPERTY DAMAGE HAZARD

Failure to follow this caution may result in property damage.
Take precautions to ensure aluminum tubes do not come in

direct contact or allow for condensate run

off with a dissimilar

metal.  Dissimilar metals can cause galvanic corrosion and

possible premature failure.

CAUTION

!

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 access door.
2. Remove rubber plugs, suction plug then liquid plug, from

coil stubs using a pulling and twisting motion. Hold coil

stubs steady to avoid bending or distorting.

3. Remove tubing plate with rubber grommets and slide plate

with grommets onto the refrigerant lines (field line

set),

away from braze joints.

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

material such as a wet cloth behind braze joints.

5. Wrap TXV and nearby tubing with a heat

sinking material

such as a wet cloth.

6. Use 1/2 psig Nitrogen purge in the suction and out the

liquid line.

7. Braze using a Sil

Fos or Phos

copper alloy. Do not use soft

solder.

8. After brazing, allow joints to cool. Carefully remove TXV

bulb insulation and verify that the TXV bulb is securely

fastened with hose clamp. Tighten screw a half

turn past

hand tight with TXV bulb placed in the indentation with

full contact with the vapor line tube. Re

wrap TXV bulb

with insulation.

9. Leak check connections before insulating entire suction

line.

10. Slide tubing plate with rubber grommets over joints.

Position tubing at center of each grommet to ensure an air

seal around the tube. Reinstall cabinet door.

UNIT DAMAGE HAZARD

Failure to follow this caution may result in product damage.
To avoid valve damage to the refrigerant control device while

brazing, valves must be wrapped with a heat

sinking material

such as a wet cloth.

CAUTION

!

PERSONAL INJURY HAZARD

Failure to follow this warning could result in personal injury.
Wear eye protection.
Coil is factory charged with 15 psi nitrogen.  The coil is under

pressure and TXV screen is in place behind liquid line plug.

DO NOT removed liquid line plug first; always remove the

suction line plug first to depressurize the coil.

WARNING

REFRIGERANT METERING DEVICE

The CAPVP coil has a factory

installed hard shut

off TXV

designed only for use with R

410A refrigerant. Use only with

outdoor units designed for R

410A.

NOTE

:  All TXV’S have preset superheat settings and are 

field

non

adjustable.

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.

CAUTION

!

CONDENSATE LINE CONNECTION

PROPERTY DAMAGE HAZARD

Failure to follow this caution may result in property damage.
When installing over a finished ceiling and/or living area,

install a field

fabricated secondary condensate pan under the

entire unit.

CAUTION

!

The coil is designed to dispose of accumulated water through

built

in condensate drain fittings. It is recommended that PVC

fittings be used on the condensate pan. Do not over

tighten. Finger

tighten plus 1

1/2 turns. Be sure to install plastic plug in unused

condensate drain fitting. Two 3/4”. female threaded pipe

connections are provided in each coil condensate pan.
A trap is not necessary on the condensate line. Consult local codes

for additional restrictions or precautions. If local codes require a

trap then the following guidelines are suggested to assure proper

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

as possible. Make trap at least 3“ (76 mm) deep and no higher than

the bottom of unit condensate drain opening (See Fig. 4). Pitch

condensate line 1” (25.4 mm) for every 10 ft. of length to an open

drain or sump. Make sure that the outlet of each trap is below its

connection to condensate pan to prevent condensate from

overflowing the drain pan. Prime all traps, test for leaks, and

insulate traps and lines if located above a living area.
