4. Use a sealing compound on male pipe threads. Install the condensate

drain line (NPT) to spill into an open drain.

5.Ensure a trap is included in the condensate drain line.

A closed return duct system shall be used. This shall not preclude use of

economizers or ventilation air intake. Flexible joints may be used in the

supply and return duct work to minimize the transmission of noise.

When fastening duct work to the side duct flanges on the unit, insert the

screws through the duct flanges only. DO NOT insert the screws through

the casing. Outdoor duct work must be insulated and waterproofed.

CAUTION

NOTE

Be sure to note supply and return openings. Refer to Fig. 2-3 and 2-5

for information concerning supply and return air duct openings.

Consult local codes for special requirements.

To provide extra protection from water damage, install an additional drain pan,

provided by installer, under the entire unit with a separate drain line. Manufac-

turer will not be responsible for any damages due to the failure to follow these

requirements.

4.1 INSTALL DRAIN PIPE

Ductwork should be sized and installed by the installing contractor in accor-

dance with the Manual D from the Air Conditioning Contractors of America, and

all national, state and local codes.

6.1 POWER WIRING

1. Proper electrical power should be available at unit. Voltage tolerance should not

be over 10% from rating voltage.

2. If any of the wire must be replaced, replacement wire must be the same type

as shown in nameplate, wiring diagram and electrical data sheet.

3. Install a branch circuit disconnect of adequate size to handle starting current,

located within sight of, and readily accessible to the unit.

4. ELECTRIC HEATER - If the Electric Heater is installed, unit may be equipped

with 30~60A. circuit breakers or fuse. 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 221 °F minimum copper conductors only.

See Electrical Data in this section for ampacity, wire size and circuit protector

requirements. Supply circuit protective devices may be either fuses or “HACR”

type circuit breakers.

• 1-3/8” knockouts inside the cabinet are provided for connection of power wiring

to electric heater.

• Power wiring is connected to the power terminal block in unit electric cabinet.

See Electrical Heater Installation Instruction for details.

6.0 ELECTRICAL WIRING

Field wiring must comply with the National Electric Code (NEC) or Canadian

Electrical Code (CEC) 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. Hazard-

ous voltage can cause severe personal injury or death.

Units are shipped without a filter or filter racks. It is the responsibility of the

installer to secure a filter in the return air ductwork or install a filter/frame Kit.

Filter must always be used and must be kept clean. Dirty filters may cause

insufficient air delivery, decreasing unit efficiency and increasing operation costs

and wear-and tear on the unit and controls.

Filters should be checked monthly; this is especially important since this unit is

used for both heating and cooling.

5.0 FILTERS

• Make sure, after installation, separation of control wiring and power wiring

has been maintained.

6.2 GROUNDING

WARNING

The unit must be permanently grounded. Failure to do so can result in

electrical shock causing personal injury or death.

• The unit must be electrically grounded in accordance with local codes or the

national electric code.

• Grounding may be accomplished by attaching ground wire(s) to ground lug(s)

provided in the unit wiring compartment.

6.3 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 50 ft, 16 AWG wire should be used.

• Two 7/8” holes can be used for control wires going into the unit, one on left

side and one at the bottom.

Thermostat should be mounted on an inside wall about 58” from floor and

will not be affected by unconditioned air, sun and/or heat exposure. Follow

the instruction carefully because there are many wiring requirements.

See Fig. 6-1 ~ 2, Table 6-1.

CAUTION

Label all wire prior to disconnection when servicing controls. Wiring errors

can cause improper and dangerous operation. Verify proper operation after

servicing.
