Goodman Mfg PG 15 specifications Electrical Power Directly To Junction Box, Horizontal Air Flow

For unit protection, use a fuse or HACR circuit breaker that is in excess of the circuit ampacity, but less than or equal to the maximum overcurrent protection device. DO NOT EXCEED THE MAXIMUM OVERCURRENT DEVICE SIZE SHOWN ON UNIT DATA PLATE.

All line voltage connections must be made through weatherproof fittings. All exterior power supply and ground wiring must be in approved weatherproof conduit. Low voltage wiring from the unit control panel to the thermostat requires coded cable. See below for ground level and rooftop wiring.

Note:Junction box location shown is optional and is for illustration purposes only.

JUNCTION BOX

Electrical Power Directly To Junction Box

Electrical Power Routed Through Bottom of Unit

Typical Electrical Wiring Unit Voltage

UNIT VOLTAGE

The unit transformer is factory connected for 230V operation. If the unit is to operate on 208V, reconnect the transformer primary lead as shown on the unit wiring diagram. The induced draft blower on some models is equipped with a low speed 230V lead (blue) and a low speed 208V lead (black). If equipped, connect the induced draft blower low speed 208V lead (black) in place of the low speed 230V lead (blue). Place the unused 230V lead on the “PARK” terminal located on ignition control.

HEAT ANTICIPATOR SETTING

The heat anticipator is to be set by measuring the load (amperage) at the “R” circuit. Follow the instructions provided with the thermostat for more details.

CIRCULATING AIR AND FILTERS

AIRFLOW CONVERSION

Units can easily be converted from horizontal to down- discharge airflow delivery. In down-discharge or high static installations, the installer should measure the total external static and review the blower performance charts before performing the installation. In some installations it will be necessary to change the blower speed to provide proper air flow.

Horizontal Air Flow

Single phase models are shipped without horizontal duct covers. If needed, these kits may be ordered through Goodman’s Service Parts department.

Duct Cover Installation

Down Discharge Applications

Cut insulation around bottom openings and remove panels from the bottom of the unit, saving the screws holding the panels in place.

NOTE: Single phase models require installation of horizontal duct kit #20464501PDGK (medium chassis) and #20464502PDGK (large chassis).

DUCTWORK

Duct systems and register sizes must be properly designed for the C.F.M. and external static pressure rating of the unit. Ductwork should be designed in accordance with the recommended methods of Air Conditioning Contractors of America Manual D (Residential) or Manual Q (Commercial).
