INTRODUCTION

The CK3B is a horizontal, multi-use cased fumace coil. (See Fig. 1.) With the use of field-supplied transition duct, these furnace coils can also

be applied to other similar horizontal furnaces on the market. The CK3B is available in sizes 024 through 060. (See Fig. 2.)

NOTE: Models with tin-plated copper coils ("T" in the 10th position of the model number) are installed the same as standard copper coils.

INSTALLATION

The unit can be installed on awork platform, secured to roof truss in an attic, suspended from hangers on floor joists in crawl space, or installed

on blocks. It is designed to allow airflow in either direction, to mate with horizontal-left (see Fig. 5) or horizontal-right (see Fig. 6) l'urnace

installations.

NOTE: Before placing ductwork on casing opening, check the rubber grommet (see Fig. 3) to ensure that the grommet is located so the bottom

end is within the condensate pan. Moisture on the header tube will run down the grommet and drip into the pan.

NOTE: Remove shipping brace l'rom both ends of casing prior to installation. Also remove corrugated shipping block l'rom inside the right end

of casing prior to installation.

PROCEDURE I--FURNACE ATTACHMENT

A. Attach coil to furnace.

The attachment plates (3) and filler plate (l) are packaged together and placed in coil carton. Remove these items, verifying the con'ect amount.

Use the following procedure to attach CK3B horizontal coil to furnace.

i. Three attachment plates are used to attach coil to furnace. Application detemfines which end of the coil will be attached to the furnace.

2. Use self-tapping screws to mount attachment plates to coil casing. (See Fig. 4A.)

3. Connect furnace snugly against coil casing.

4. Use self-tapping screws to attach fumace. (See Fig. 4B.)

5. Seal joint between coil casing and furnace to create air tight seal using locally approved materials.

PROCEDURE 4--REFRIGERANT LINES

Refi'igerant lines nmst be configured per local buikling codes. Lay out lines in relation to specifications and job site requirements.

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 refrigerant line sets or field-supplied lines of refi'igerant grade. Ahvays evacuate lines

and reclaim rel}igerant when making connections or flaring refrigerant lines. Leak check connections before insulating entire suction line.

CAUTION: If unit is to be installed on system with a thermostatic expansion valve, removal of indoor coil piston is

required. Failure to follow this CAUTION could result in minor personal injury or product and property damage.

A. Suction Line

Suction line is designed for field sweat connections. Provide inverted loop on suction line if line set exceeds 50 ft. per long line application guide.

Sweat stub has a rubber shipping plug to keep out moisture and dirt. Remove plug only when ready to make field sweat connection.

CAUTION: To avoid damage while brazing, wrap tubing or fittings with a heat-sinking material such as a wet cloth.

Failure to follow this CAUTION could result in minor personal injury or product and property damage.

B. Liquid Line

Liquid line is designed lbr sweat connection. During installation these steps should be followed:

i. Replace piston, if required. Check piston size stmnped into side of brass hex nut. (See Fig. 8.) If piston number does not match required

piston shown on outdoor unit rating plate, replace indoor piston with piston shipped with outdoor unit.

2. When piston is replaced finger tighten plus i/4 turu.

CAUTION: Remove Teflon seal during brazing. Replace when fitting has cooled. Failure to follow this CAUTION could

result in minor personal injury or product and property damage.

3. Liquid stub has a rubber shipping plug to keep out moisture and dirt. Remove plug only when ready to make field sweat connection.

SYSTEM REFRIGERANT CONTROL

A refrigerant control device (bypass type) is factory supplied with coil. (See Table 2.) The piston has a refrigerant metering hole through it, and

is field replaceable.

The piston shipped with indoor coil may be different from piston shipped with outdoor condensing unit. If this is the case, change the indoor piston.

Ahvays use piston shipped with outdoor condensing unit.

PROCEDURE 6--CONNECT CONDENSATE DRAIN LINE

The CK3B 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.

Install a trap in condensate line as close to the CK3B coil as possible. Make trap at least 2 1,4 in. deep and not higher than the bottom of unit

condensate &ain openings. (See Fig. 9.)

NOTE: If unit is located in or above a living space where damage may result form 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 fl:om unit into 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 in. condensate line (with appropriate trap) to a place where condensate will be noticeable. The

owner of the structure must be infonned that when condensate flows from the secondary drain or external condensate pan, the unit requires

servicing or water damage will occur.
