2. CRANKCASE HEATER

Scroll equipped units do not have and do not require a crank-

case heater.

3. TIME DELAY COMPONENT

The time delay is located in the low voltage control circuit.

When the compressor shuts off due to thermostat operation

or a power failure, this components keeps the compressor off

for at least 30 seconds which allows the system pressure to

equalize.

4. UNBRAZING SYSTEM COMPONENTS

If the refrigerant charge is removed from a scroll equipped

unit by bleeding the high side only, it is sometimes possible

for the scrolls to seal, preventing pressure equalization through

the compressor. This may leave the low side shell and suc-

tion line tubing pressurized. If a brazing torch is then applied

to the low side while the low side shell and suction line con-

tains pressure, the pressurized refrigerant and oil mixture

could ignite when it escapes and contacts the brazing flame.

To prevent this occurrence , it is important to check both the

high and low side with manifold gauge before unbrazing, bleed

refrigerant from both the high and low side.

IMPORTANT MESSAGE TO OWNER:

These instructions should be carefully read and kept for

future reference. It is suggested that this booklet be saved for

future references. It is addressed to your dealer and service-

man, but we highly recommend you read it, paying particular

attention to the section titled MAINTENANCE.

The manufacturer assumes no responsibility for equipment

installed in violation of any code or regulation. The manual will

instruct you in the service and care of your unit. Have your

installer go over the manual with you so that you fully under-

stand your air conditioner and how it is intended to function.

The heat pump is a relatively simple device. It operates

exactly as a summer air conditioning unit on the cooling

cycle. Always let the thermostat control system operation. Do

Not try to second guess the thermostat or tamper with it. If the

conditioned area temperature is not suitable, change the

thermostat setting one degree at a time until desired comfort

level is achieved.

A heat pump in the heating mode cannot heat a building as

rapidly as a furnace heats it. It may take a day or two to “pull

down” a cold, moist house when the unit is initially installed

or after prolonged shutdowns.

MAINTENANCE

It is recommended that the outdoor unit be inspected and, if

necessary, cleaned each cooling season. Particular attention

should be given to the air inlet side of the outdoor coil to in-

sure that leaves, grass, etc., are not being drawn into the

unit. Restriction to air flow across the coil will result in loss of

system capacity, high operating pressures and excessive

operating costs. If the outdoor unit is installed adjacent to a

grassy area, it is suggested that lawn mowers be routed in

such a manner that the discharge of the mower will be di-

rected away from the unit. There must be air filters installed

in the system at some point upstream to the indoor coil. Air

filters should be inspected and, if necessary, replaced and/

or cleaned AT LEAST once a month.

If disposable filters are used, an adequate supply of clean,

unused filters of the correct size should be kept available.

Equipment should never be operated without filters.

Permanent type filters may be vacuumed and/or washed but

should not be reinstalled until thoroughly dry. Most air filters

are marked to indicate the direction of air flow, and this should

be carefully noted when they are being installed. Never turn

a dirty filter to allow air flow in the opposite direction.

The blower and motor bearings are permanently lubricated

and do not require additional lubrication.

EQUIPMENT

Some outdoor units have corresponding heaters that are

factory wired in such a manner that they are in operation

whenever the main power supply to the unit is on. Before

starting equipment after prolonged shutdowns or at the

time of initial start up, be sure that the circuits to the units

are closed for at least 24 hours.

APPLICATION

It is not the intent of the manufacturer that this equipment be

used with components other than indicated.

Do not connect to or use any device that is not design-

certified by Goodman for use with this unit. Serious

property damage, personal injury, reduced unit

performance and/or hazardous conditions may result

from the use of such non-approved devices.

ues And Approved System Matches.

LOCATION

The outdoor unit should be located so that air flow through

the coil is unrestricted. To provide adequate service access,

do not locate service side closer than 30.5 cm to any wall or

obstruction.

Consider the affect of outdoor fan noise on conditioned space

and any adjacent occupied space. It is recommended that the

unit be placed so that discharge does not blow toward

windows less than 7.6 m away.

The outdoor unit should be set on a solid, level foundation -

preferably a concrete slab at least 10.2 cm thick. The slab

should be above ground level and surrounded by a graveled

area for good drainage. Any slab used as a unit foundation

should not adjoin the building as it is possible that sound and

vibration may be transmitted to the structure. For rooftop

installation, steel or treated wood beams should be used as

unit support for load distribution.
