operation, check refrigerant charge using charging information

located on control box cover and/or in the Check Charge section of

this instruction.

IMPORTANT: Maximum liquid--line size is 3/8--in. OD for all

residential applications including long line.

IMPORTANT: Always install the factory--supplied liquid--line

filter drier. Obtain replacement filter driers from your distributor or

branch.

INSTALLATION

Specifications for this unit in residential new construction market

require the outdoor unit, indoor unit, refrigerant tubing sets,

metering device, and filter drier listed in presale literature. There

can be no deviation. Consult the Application Guideline and

Service Manual – Air Conditioners and Heat Pumps Using Puronr

Refrigerant to obtain required unit changes for specific applications

andforR--22retrofit.

Check Equipment and Job Site

Unpack Unit

Move to final location. Remove carton taking care not to damage

unit.

Inspect Equipment

File claim with shipping company prior to installation if shipment

is damaged or incomplete. Locate unit rating plate on unit corner

panel. It contains information needed to properly install unit.

Check rating plate to be sure unit matches job specifications.

Install on a Solid, Level Mounting Pad

If conditions or local codes require the unit be attached to pad, tie

down bolts should be used and fastened through knockouts

provided in unit base p an. Refer to unit mounting pattern in Fig. 2

to determine base pan size and knockout hole location.

For hurricane tie downs -- contact your local distributor for details

and PE (Professional Certification), if required by local authorities.

On rooftop applications, mount on level platform or frame. Place

unit above a load--bearing wall and isolate unit and tubing set from

structure. Arrange supporting members to adequately support unit

and minimize transmission of vibration to building. Consult local

codes governing rooftop applications.

Roof mounted units exposed to winds may require wind baffles.

Consult the Application Guideline and Service Manual --

Residential Split System Air Conditioners and Heat Pumps Using

Puronr Refrigerant for wind baffle construction.

NOTE: Unit must be level to within ±2_ (±3/8 in./ft..) per

compressor manufacturer specifications.

Clearance Requirements

Wh en in stallin g, allow su fficient space fo r airflow clearan ce,

wiring, refrigerant piping, and service. Allow 30 in. (762 mm)

clearance to service end of unit and 48 in. (1219.2 mm) above unit.

For proper airflow, a 6 in. (152.4 mm) clearance on one side of

unit and 12 in. (304.8 mm) on all remaining sides must be

maintained. Maintain a distance of 24 in. (609.6 mm) between

units. Position so water, snow, or ice from roof or eaves cannot fall

directly on unit.

WARNING

PERSONAL INJURY AND ENVIRONMENTAL

HAZARD

Failure to follow this warning could result in personal injury

or death.

Relieve pressure and recover all refrigerant before system

repair or final unit disposal.

Use all service ports and open all flow--control devices,

including solenoid valves.

CAUTION

UNIT DAMAGE HAZARD

Failure to follow this caution may result in equipment

damage or improper operation.

Do not leave system open to atmosphere any longer than

minimum required for installation. POE oil in compressor is

extremely susceptible to moisture absorption. Always keep

ends of tubing sealed during installation.

If ANY refrigerant tubing is buried, provide a 6 in. (152.4

mm) vertical rise at service valve. Refrigerant tubing lengths

up to 36 in. (914.4 mm) may be buried without further

special consideration. Do not bury lines more than 36 in.

(914.4 mm).
