Pre-Installation Instructions
Carefully read all instructions for the installation prior to in-
stalling product. Make sure each step or procedure is under-
stood and any special considerations are taken into account
before starting installation. Assemble all tools, hardware and
supplies needed to complete the installation. Some items may
need to be purchased locally. Make sure everything needed to
install the product is on hand before starting.
Application Information
Install this coil upstream (discharge air) of the furnace and
install downstream (return air) of the air handler. This coil is bi-
directional coil and can be installed in either the left or right
direction. Determine the coil direction by the side that allows
the best access.
RIGHT APPLICATION LEFT APPLICATION

Front View (for Right & Left Hand Application)
There is no conversion required to reverse from right to left
application. Attach the duct flanges to the discharge side of
the unit. If the coil and furnace combination are not similar in
depth and width, use a field-supplied transition to center the
furnace and coil openings (see figure 3). The supplied Z-bracket
attachment should be used to attach the coil to a narrower
furnace when the furnace is one size smaller than the coil (i.e.
coil height = 17.5-inches and furnace width = 14-inches) (See
figure 3). Figure 3a indicates incorrect coil/furnace attach-
ment method.

Condensate Drain Piping
When coils are installed above ceilings, or in other locations
where damage from condensate overflow may occur, it is MAN-
DATORY to install a field-fabricated auxiliary drain pan under
the coil cabinet enclosure. Drain lines from the auxiliary pan
must be installed and terminated so that the homeowner can
see water discharges.
The coil drain pan has a primary and an optional secondary
drain with 3/4" NPT female connections. The connectors re-
quired can be 3/4" NPT male either PVC or metal pipe and
should be hand tightened to a torque of no more than 37 in-lbs.
to prevent damage to the drain pan connection. An insertion
depth between .355 to .485 inches (3-5 turns) should be ex-
pected at this torque. If using a copper drain line, solder a
short piece of pipe to the connector before installing a drain
fitting. DO NOT over torque the 3/4” copper connector to the
plastic drain connection.
1. Ensure drain pan hole is NOT obstructed.
2. To prevent potential sweating and dripping on finished
space, it may be necessary to insulate the condensate
drain line located inside the building. Use Armaflex
®
or
similar material.
3
A Secondary Condensate Drain Connection has been pro-
vided for areas where the building codes require it. Pitch the
drain line 1/4" per foot to provide free drainage. Insulate
drain lines (primary and secondary) located inside the build-
ing to prevent sweating. Install a condensate trap in the pri-
mary drain line to ensure proper drainage. If the secondary
line is required, run the line separately from the primary drain
and end it where it can be easily seen.
NOTE: Water coming from this line means the coil primary
drain is plugged and needs clearing.
If secondary drain is not installed, the secondary access
must be plugged.
CAUTION
NOTE: Trapped lines are required by many local codes. In the
absence of any prevailing local codes, please refer to the
requirements listed in the Uniform Mechanical Building Code.
A drain trap in a draw-through application prevents air from
being drawn back through the drain line during fan operation
thus preventing condensate from draining, and if connected to
a sewer line to prevent sewer gases from being drawn into the
airstream during blower operation. In a blow-through applica-
tion the drain trap prevents conditioned air from escaping. It is
permissible in this application to use a shallow trap design
sometimes referred to as a running trap.

Figure 4
Condensate Drain Trap
The depth of a running trap (Figure 5) should be either 1" or a
depth that permits unrestricted condensate drainage without
excessive air discharge.
Field experience has shown condensate drain traps with an
open vertical Tee between the air handler and the condensate
drain trap can improve condensate drainage in some applica-
tions, but may cause excessive air discharge out of the open
Tee. The manufacturer does not prohibit this type of drain but
we also do not recommend it due to the resulting air leakage.
Regardless of the condensate drain design used, it is the
installer’s responsibility to ensure the condensate drain sys-
tem is of sufficient design to ensure proper condensate re-
moval from the coil drain pan.

Horizontal Coil Water Blower-Off Bracket
CHPF4860 coils are shipped with an accessory kit containing
a sheet metal bracket. For horizontal-left applications where
the airflow may exceed 1600 CFM, this bracket must be
installed on the left side of the drain pan as shown in Figure 6.

Refrigerant Lines
A quenching cloth is strongly recommended to
prevent scorching or marring of the equipment
finish when welding close to the painted surfaces.
Use brazing alloy of 5% minimum silver content.
WARNING
All cut ends are to be round, burr free, and cleaned. Any other
condition increases the chance of a refrigerant leak. Use a
pipe cutter to remove the closed end of the spun closed suc-
tion line.
To avoid overheating after brazing, quench all welded joints
with water or a wet rag.
For the correct tubing size, follow the specification for the con-
denser/heat pump
4
The coil is shipped under pressure. Follow these
instructions to prevent injury.
WARNING
Applying too much heat to any tube can melt the tube. Torch
heat required to braze tubes of various sizes must be
proportional to the size of the tube. Service personnel must
use the appropriate heat level for the size of the tube being
brazed.
CAUTION
NOTE: Tubes of smaller size require less heat to bring the
tube to brazing temperature before adding brazing alloy. The
use of a heat shield when brazing is recommended to avoid
burning the serial plate or the finish on the unit.
Special Instructions
This coil comes equipped with a check style flowrator for refrig-
erant management. For most installations with matching ap-
plications, no change to the flowrator orifice is required. How-
ever, in mix-matched applications, a flowrator change may be
required. See the Piston Kit Chart or consult your local dis-
tributor for details regarding mix-matched orifice sizing. If the
mix-match application requires a different piston size, change
the piston in the distributor on the indoor coil before installing
the coil and follow the procedure shown below.
1. Loosen the 13/16 nut 1 TURN ONLY to allow high pres-
sure tracer gas to escape. No gas indicates a possible
leak.
2. After the gas has escaped, remove the nut and discard
the plastic or brass cap.
3. Remove the check piston to verify it is correct and then
replace the piston. See piston kit chart in instructions.
4. Use a tube cutter to remove the spin closure on the suc-
tion line.
5. Slide the 13/16 nut into place on the tailpiece supplied in
the literature bag or with the unit.
6. Braze tailpiece to the line set liquid tube.
Figure 7
Flowrator
7. Insert the suction line into the connection, slide the insu-
lation and the rubber grommet at least 18" away from the
braze joint. Braze suction line.
8. AFTER THE TAILPIECE HAS COOLED, confirm posi-
tion of the white Teflon
®
seal and hand tighten the 13/16
nut.
9. Torque the 13/16 nut to 10-25 ft-lbs. or tighten 1/6 turn.
Excessive torque can cause orifices to stick. Use the proper
torque settings when tightening orifices.
CAUTION
10. Replace suction line grommet and insulation.

NOTE: With the piston in the distributor, the seal end should
point inside the distributor body and should not be seen when
looking into the end of distributor. Make sure the piston is free
to rotate, and move up and down in the distributor body.
IMPORTANT: Note 2 in the Piston Kit Chart does not apply to
CH coils.
Aluminum Indoor Coil Cleaning
(Qualified Servicer Only)
This unit is equipped with an aluminum tube evaporator coil.
The safest way to clean the evaporator coil is to simply flush
the coil with water. This cleaning practice remains as the
recommended cleaning method for both copper tube and alu-
minum tube residential cooling coils.
An alternate cleaning method is to use one of the products
listed in the technical publication TP-109 (shipped in the lit-
erature bag with the unit) to clean the coils. The cleaners
listed are the only agents deemed safe and approved for use to
clean round tube aluminum coils. TP-109 is available on the
web site in Partner Link > Service Toolkit.
NOTE: Ensure coils are rinsed well after use of any chemical
cleaners.
