C. RECOMMENDATIONS

CAUTION

This coil is pressurized with 8-12 psig of dry air. Do

not stand directly in front of the coil connections when

removing sealing plugs. If no pressure is released,

check for leaks.

1. If this coil is a part of the total system installation, then

use the Installer’s Guide packaged with the furnaces,

Heat Pump outdoor sections, and Control Center for

physically installing those components.

2. It is recommended that the outline drawing

(page 2) be studied and dimensions properly noted

and checked against selected installation site. By

noting in advance proper clearance allowances for

installation and possible future service of the coil.

D. INSTALLING 4TXFH COIL/

ENCLOSURE

Coil/enclosure assembly can be used for all horizontal

furnaces (gas and electric) applications (Figure 1), and

for applications of vertical upow furnaces (Figure 2),

where the top clearance is insu󰀩cient for installing an

“A” coil and enclosure, and there is access to a run of

horizontal duct.

WARNING

WARNING (Medium/high pressure)

Contains Refrigerant!

System contains oil and refrigerant under high pressure. Recover

refrigerant to relieve pressure before opening the system. See

unit nameplate for refrigerant type. Do not use non-approved

refrigerants, refrigerant substitutes, or refrigerant additives.

Failure to follow proper procedures or the use of non-approved

refrigerants, substitutes, or refrigerant additives could result in

death, serious injury, or equipment damage.

Installer’s Guide

Since coil/ enclosure assembly must be installed within

the horizontal run of duct, a transition duct must be

fabricated to mate with the furnace supply outlet duct

ange on one end and the duct ange connection on the

coil/ enclosure assembly on the other end.

For maximum performance, it is recommended that the

transition duct be at least 2 feet in length.

1. Secure the transition duct to the furnace with the

furnace in position.

2. The refrigerant lines and condensate connections of

cased coils may be on either side of the supply air

duct. The air may be directed through the coil from

either side of the coil.

3. Attach the coil/ enclosure assembly to the transition

from the furnace, providing proper support for coil/

enclosure assembly’s weight. Keep the coil level.

Extra pitch is not required for coil to drain properly.

4. Secure the downstream side of coil/ enclosure

assembly to the supply air duct.

NOTE:

Secure properly so there will be no air leakage.

5. The indoor coil must be evacuated through the

refrigerant lines at the outdoor unit before opening

the service valves. See evacuation procedure in Field

Fabricated Refrigerant Lines section of the Installer’s

Guide for the outdoor unit.

6. Complete the installation of the unit per installation

instructions.

E. INSTALLING/BRAZING REFRIGERANT

LINES

CAUTION

Do NOT open refrigerant valve at the outdoor unit

until the refrigerant lines and coil have been brazed,

evacuated, and leak checked. This would cause

contamination of the refrigerant or possible discharge

of refrigerant to the atmosphere.

③

1. The following steps are to be considered when

installing the refrigerant lines:

a.Determine the most practical way to run the lines.

b.Consider types of bends to be made and space

limitations.

c. Route the tubing making all required bends and

properly secure the tubing before making nal

connections.

NOTE:

Refrigerant lines must be isolated from the structure and

the holes must be sealed weather tight after installation.

IMPORTANT:

Do not unseal refrigerant tubing until ready to t

refrigerant lines.

There is only a holding charge of dry air in the indoor coil,

therefore no loss of operating refrigerant charge occurs

when the sealing plugs are removed.

NOTE:

TXV bulb MUST be protected (wrapped with wet rag)

or removed, while brazing the tubing. Overheating

of the sensing bulb will affect the functional

characteristics and performance of the comfort coil.

Installer’s Guide

PAINTED AREAS OF THE UNIT MUST BE SHIELDED

DURING BRAZING.

4. Flow a small amount of nitrogen through the tubing

while brazing.

5. Use good brazing technique to make leakproof

joints.

6. Minimize the use of sharp 90 degree bends.

7. Insulate the suction line and its ttings.

8. Do NOT allow un-insulated lines to come into contact

with each other.

NOTE:

Torque specication for TXV equals 1/6 turn past nger

tight. Make sure to backwrench when tightening as

shown in Firgure 3.

F. LEAK CHECK

1. Using a manifold gauge, connect an external supply

of dry nitrogen to the gauge port on the liquid line.

2. Pressurize the connecting lines and indoor coil to

150 PSIG maximum.

3. Leak check brazed line connections using soap

bubbles. Repair leaks (if any) after relieving

pressure.

4. Evacuate and charge the system per the instructions

packaged with the outdoor unit.

G. CONDENSATE DRAIN PIPING

(SEE FIGURE 5)

NOTE:

When coils are installed above ceilings or in other

locations where damage from condensate overow

may occur. A eld fabricated auxiliary drain pan shall be

installed under the coil enclosure. Drain lines from this

pan must be installed, but should NOT be connected to

the primary drain.

Condensate drain connections are located in the drain pan

at the bottom of the coil/enclosure assembly. The female

threaded tting protrudes outside of the enclosure for

external connection. A eld fabricated trap is not required

for proper drainage due to the positive pressure of the

furnace; however, it is recommended to prevent e󰀩ciency

loss of conditioned air.

1. The drain hole in the drain pan must be cleared of all

insulation.

2. Insulate the primary drain line to prevent sweating

where dew point temperatures may be met.

(Optional depending on climate and application

needs).

FIELD FABRICATED TRAP

⑤

2" MIN.

CAP OR PLUG

Trap must be within 4'

of furnace / air handler

condensate drain connection.

Close as possible

When replacing the bulb and hose clamp, the clamp

should be "snug" but not "tight" - spec is to torque the

hose clamp to 20+/-5in-lb.

H. SECONDARY CONDENSATE DRAIN

A secondary condensate drain connection, now called for

by many building codes, has been provided, on 4TXFH

coils. Reducing ttings and copper tubing can be used in

most cases.

IMPORTANT:

Plug all drain line connection(s) not used. Do NOT use

heat or torch near drain ttings.

I. DUCT CONNECTIONS

The supply and return air duct should be connected to

the unit with a ame retardant duct connectors. Duct

ange connections are provided at both supply and

discharge openings of the coil.

④

1. Remove both sealing rubber plugs from the indoor

coil.

2. Field supplied tubing should be cut square, round

and free of burrs at the connecting end. Clean the

tubing to prevent contaminants from entering the

system.

3. Run the refrigerant tubing into the stub tube sockets

of the indoor unit coil.
