3.2 VERTICAL DOWNFLOW
Conversion to Vertical Downflow: A vertical upflow unit may be
converted to vertical downflow. Remove the door and indoor coil and
reinstall 180° from original position. See Fig.8.
IMPORTANT: To comply with certification agencies and the National
Electric Code for downflow application, the circuit breaker(s) on
field-installed electric heater kits must be re-installed per procedure
below so that the breaker switch “on” position and marking is up and,
“off” position and marking is down.
To rotate breaker(s): Rotate one breaker set (circuit) at a time
starting with the one on the right. Loosen both lugs on the load
side of the breaker. (Make sure that wires are identified and are
reinstalled into proper breaker).Wires are bundled with wire ties,
one bundle going to the right lug and one bundle going to the left
lug.
Using a screwdriver or pencil, lift white plastic tab with hole
away from breaker until breaker releases from mounting
opening.
With breaker held in hand, rotate breaker so that “on” position
is up, “off” position is down with unit in planned vertical
mounting position. insert right wire bundle into top right breaker
lug, ensuring all strands of all wires are inserted fully into lug,
and no wire insulation is in lug.
Tighten lug as tight as possible while holding circuit breaker.
Check wires and make sure each wire is secure and none are
loose. Repeat for left wire bundle in left top circuit breaker lug.
Replace breaker by inserting breaker mounting tab opposite
white pull tab in opening, hook mounting tab over edge in
opening.
With screwdriver or pencil, pull blue tab with hole away from
breaker while setting that side of breaker into opening. When
breaker is in place, release tab, locking circuit breaker into
location in opening.
Repeat above operation for remaining breaker(s) (if more than
one is provided).
Replace single point wiring jumper bar, if it is used, on line side
of breaker and tighten securely.
Double check wires and lugs to make sure all are secure and
tight. Check to make sure unit wiring to circuit breaker load lugs
match that shown on the unit wiring diagram.

4.3 GROUNDING
4. ELECTRICAL WIRING
Field wiring must comply with the National Electric Code (C.E.C. in
Canada) and any applicable local ordinance.
WARNING
Disconnect all power to unit before installing or servicing. More
than one disconnect switch may be required to de-energize the
equipment. Hazardous voltage can cause severe personal injury
or death.
4.1 POWER WIRING
It is important that proper electrical power is available for connection
to the unit model being installed. See the unit nameplate, wiring
diagram and electrical data in the installation instructions.
3.4 INSTALLATION IN AN UNCONDITIONED SPACE
IMPORTANT: There are two pairs of coil rails in the air handler for
default and counter flow application. If the air handler is installed in
an unconditioned space, the two unused coil rails should be removed
to minimize air handler surface sweating. The coil rails can be easily
removed by taking off the 6 mounting screws from both sides of the
cabinet.
4.2 CONTROL WIRING
IMPORTANT: Class 2 low voltage control wiring should not be run in
conduit with main power wiring and must be separated from power
wiring, unless class 1 wire of proper voltage rating is used.
Low voltage control wiring should be 18 Awg. color-coded. For
lengths longer than 100 ft., 16 Awg. wire should be used.
Low voltage control connections are made to low voltage pigtails
extending from top of air handler (upflow position - see Fig3).
Connections for control wiring are made with wire nuts. Control
wiring knockouts (5/8
＂ and 7/8 ＂ ) are also provided on the right
and left side of the unit for side connection.
See wiring diagrams attached to indoor and outdoor sections to
be connected.
Make sure, after installation, separation of control wiring and
power wiring has been maintained.
Grounding may be accomplished by grounding metal conduit
when installed in accordance with electrical codes to the unit
cabinet.
Grounding may also be accomplished by attaching ground
wire(s) to ground lug(s) provided in the unit wiring compartment.
Ground lug(s) are located close to wire entrance on left side of
unit (up-flow). Lug(s) may be moved to marked locations near
wire entrance on right side of unit (up-flow). If alternate location is
more convenient.
Use of multiple supply circuits require grounding of each circuit to
lug(s) provided in unit.
Horizontal units must be configured for right hand air supply or left
hand air supply. Horizontal drain pan must be located under
indoor coil. Failure to use the drain pan can result in property
damage.
CAUTION
WARNING
The unit must be permanently grounded. Failure to do so can
result in electrical shock causing personal injury or death.
If required, install a branch circuit disconnect of adequate size,
located within sight of, and readily accessible to the unit.
IMPORTANT: After the Electric Heater is installed, units may be
equipped with one two or three 30-60 amp. circuit breakers.
These breaker(s) protect the internal wiring in the event of a short
circuit and serve as a disconnect. Circuit breakers installed within
the unit do not provide over-current protection of the supply wiring
and therefore may be sized larger than the branch circuit
protection.
Supply circuit power wiring must be 75°C minimum copper
conductors only. See Electrical Data in this section for ampacity,
wire size and circuit protector requirement. Supply circuit
protective devices may be either fuses or “HACR” type circuit
breakers.
Power wiring may be connected to either the right, left side or top.
Three 7/8＂, 1-3/8＂, 1-3/4＂ dia. concentric knockouts are
provided for connection of power wiring to unit.
Power wiring is connected to the power terminal block in unit
electric cabinet.
Conversion in Horizontal Direction: Horizontal right-hand supply can
be changed to horizontal left-hand supply by removing the indoor coil
and reinstalling 180° from original.

NOTES: Airflow based upon cooling performance at 230V with no electric heat and no filter.Airflow at 208V is approximately the same as 230V
because the mult-tap ECM motor is a constant torque motor. The torque doesn’t drop off at the speeds in which the motor operates.
The air distribution system has the greatest effect on airflow. The duct system is totally controlled by the contractor. For this reason, the contractor
should use only industry-recognized procedures.
Heat pump systems require a specified airflow for electric heat operating. Each ton of cooling requires between 350 and 450 cubic feet of air per
minute (CFM), or 400 CFM nominally.
Duct design and construction should be carefully done. System performance can be lowered dramatically through bad planning or workmanship.
Air supply diffusers must be selected and located carefully. They must be sized and positioned to deliver treated air along the perimeter of the
space. If they are too small for their intended airflow, they become noisy. If they are not located properly, they cause drafts. Return air grilles must
be properly sized to carry air back to the blower. If they are too small, they also cause noise.
The installers should balance the air distribution system to ensure proper quiet airflow to all rooms in the home. This ensures a comfortable living
space.
An air velocity meter or airflow hood can be used to balance and verify branch and system airflow (CFM).

7. REFRIGERANT CONNECTIONS
Keep the coil connections sealed until refrigerant connections are
made. See the Installation Instructions for the outdoor unit for details
on line sizing, tubing installation, and charging information.
Coil is shipped with Nitrogen. Evacuate the system before charging
with refrigerant.
Install refrigerant tubing so that it does not block service access to
the front of the unit.
Nitrogen should flow through the refrigerant lines while brazing.
Use a brazing shield to protect the cabinet’s paint and a wet rag to
protect the rubber grommet and input pipe’s pistion seal ring from
being damaged by torch flames.
After the refrigerant connections are made, seal the gap around the
connections with pressure sensitive gasket.
Do not, under any circumstances, connect return ductwork to any
other heat producing device such as fireplace insert, stove, etc.
Unauthorized use of such devices may result in fire, carbon
monoxide poisoning, explosion, personal injury or property
damage.
Sheet metal ductwork run in unconditioned spaces must be insulated
and covered with a vapor barrier. Fibrous ductwork may be used if
constructed and installed in accordance with SMACNA Construction
Standard on Fibrous Glass Ducts. Ductwork must comply with
National Fire Protection Association as tested by UL Standard 181 for
Class I Air Ducts. Check local codes for requirements on ductwork
and insulation.
Duct system must be designed within the range of external static
pressure the unit is designed to operate against. It is important
that the system airflow be adequate. Make sure supply and return
ductwork, grills, special filters, accessories, etc. are accounted for
in total resistance. See airflow performance tables in this manual.
Design the duct system in accordance with “ACCA” Manual “D”
Design for Residential Winter and Summer Air Conditioning and
Equipment Selection. Latest editions are available from: “ACCA”
Air Conditioning Contractors of America, 1513 16th Street, N.W.,
Washington, D.C. 20036. If duct system incorporates flexible air
duct, be sure pressure drop Information (straight length plus all
turns) shown in “ACCA” Manual “D” is accounted for in system.
Supply plenum is attached to the 3/4” duct flanges supplied with
the unit. Attach flanges around the blower outlet.
IMPORTANT: If an elbow is included in the plenum close to the
unit, it can not be smaller than the dimensions of the supply duct
flange on the unit.
IMPORTANT: The front flange on the return duct if connected to
the blower casing must not be screwed into the area where the
power wiring is located. Drills or sharp screw points can damage
insulation on wires located inside unit.
Secure the supply and return ductwork to the unit flanges, using
proper fasteners for the type of duct used and tape the
duct-to-unit joint as required to prevent air leaks.
WARNING
6. DUCTWORK
Field ductwork must comply with the National Fire Protection
Association NFPA 90A, NFPA 90B and any applicable local
ordinance.
WARNING
Use a wet rag to protect the two seal ring in the input pipe from
being damaged by torch flames while brazing.
After the work is finished,make sure to check that there is no vapor
leak After checking for vapor leaks,be sure to insulate the piping
connections referring to Fig.10.

Auxiliary drain line should be run to a place where it will be
noticeable if it becomes operational. Homeowner should be
warned that a problem exists if water should begin running from
the auxiliary drain line.
Plug the unused drain connection with the plugs provided in the
parts bag, using a thin layer of teflon paste, silicone or teflon
tape to form a water tight seal.
Test condensate drain pan and drain line after installation is
complete. Pour water into drain pan, enough to fill drain trap and
line. Check to make sure drain pan is draining completely, no
leaks are found in drain line fittings, and water is draining from
the termination of the primary drain line.
Be sure to insulate the drain piping and drain socket since
condensation may cause water leakage.
Be sure to install a drain trap at the drain outlet since the inside
of the unit is at negative pressure relative to atmospheric
pressure during operation.
13
8. AIR FILTER (not factory-installed)
External filter or other means of filtration is required. Units should be
sized for a maximum of 300 feet/min air velocity or what is recomm-
ended for the type filter installed.
Filter application and placement are critical to airflow, which may affect
the heating and cooling system performance. Reduced airflow can
shorten the life of the system’s major components, such as motor,
limits, elements, heat relays, evaporator coil or compressor.
Consequently, we recommend that the return air duct system have
only one filter location. For systems with a return air filter grill or
multiple filter grills, can have a filter installed at each of the return air
openings.
If adding high efficiency filters or electronic air filtration systems, it is
very important that the air flow is not reduced. If air flow is reduced the
overall performance and efficiency of the unit will be reduced. It is
strongly recommended that a professional installation technician is
contacted to ensure installation of these such filtration systems are
installed correctly.
IMPORTANT: Do not double filter the return air duct system. Do not
filter the supply air duct system. This will change the performance of
the unit and reduce airflow .
7.1 CONDENSATE DRAIN TUBING
Consult local codes for specific requirements.
IMPORTANT:
1. When making drain fitting connections to the drain pan, use a thin
layer of Teflon paste, silicone or Teflon tape and install, hand tighten.
2. When making drain fitting connections to drain pan, do not
overtighten. Over tightening fittings can split pipe connections on the
drain pan.
CONDENSATE DRAIN TRAP
DO NOT OVERTIGHTEN DRAIN FITTING

UNIT
TO APPROVED DRAIN
Install drain lines so they do not block service access to front of
the unit. Minimum clearance of 24 inches is required for filter, coil
or blower removal and service access.
Make sure unit is level or pitched slightly toward primary drain
connection so that water will drain completely from the pan. (See
Fig.11)
Do not reduce drain line size less than connection size provided
on condensate drain pan. Use 3/4 ＂ PVC piping for drain piping
connections.
All drain lines must be pitched downward away from the unit a
minimum of 1/8 ＂ per foot of line to ensure proper drainage.
Do not connect condensate drain line to a closed or open sewer
pipe. Run condensate to an open drain or run line to a safe
outdoor area.
The drain line should be insulated where necessary to prevent
sweating and damage due to condensate forming on the outside
surface of the line.
Make provisions for disconnecting and cleaning of the primary
drain line should it become necessary. Install a 3 inch trap in the
primary drain line as close to the unit as possible. Make sure that
the top of the trap is below connection to the drain pan to allow
complete drainage of pan (See Fig. 11).
DO NOT OPERATE UNIT WITHOUT
CONDENSATE DRAIN TRAP.

WARNING
Do not operate the system without filters. A portion of the dust entrained in the air may temporarily lodge In the duct runs and at the supply
registers. Any circulated dust particles could be heated and charred by contact with the air handler elements. This residue could soil ceilings,
walls, drapes, carpets and other articles in the house.
Soot damage may occur with filters in place, when certain types of candles, oil lamps or standing pilots are burned.

This coil comes with a factory installed piston metering device. See Table 1 for factory installed piston
size. Some system combinations will require a different sized piston to be field installed.
Contact your local parts center to order the appropriate MAYORIACHP piston kit for your system
combination.
Use Table 3 for TXV kit part numbers.
A TXV may be required to achieve minimum efficiency ratings or for long refrigerant line set
applications. Reference AHRI for system combination ratings.
Reference Table 4 to charge the system by superheat when using a piston. Reference the outdoor unit
installation guide to change the system by subcooling when using a TXV.
