INSTALLATION RECOMMENDATIONS

NOTE: In some cases noise in the living area has been traced to gas pulsations from improper installation of equipment.

1.Locate unit away from windows, patios, decks, etc. where unit operation sound may disturb customer.

2.Ensure that vapor and liquid tube diameters are appropriate for unit capacity.

3.Run refrigerant tubes as directly as possible by avoiding un- necessary turns and bends.

4.Leave some slack between structure and unit to absorb vi- bration.

5.When passing refrigerant tubes through the wall, seal open- ing with RTV or other pliable silicon-based caulk. (See Fig. 1.)

6.Avoid direct tubing contact with water pipes, duct work, floor joists, wall studs, floors, and walls.

7.Do not suspend refrigerant tubing from joists and studs with a rigid wire or strap which comes in direct contact with tubing (See Fig. 1.)

8.Ensure that tubing insulation is pliable and completely sur- rounds vapor tube.

9.When necessary, use hanger straps which are 1 in. wide and conform to shape of tubing insulation. (See Fig. 1.)

10.Isolate hanger straps from insulation by using metal sleeves bent to conform to shape of insulation.

When outdoor unit is connected to factory-approved indoor unit, outdoor unit contains system refrigerant charge for operation with ARI rated indoor unit when connected by 15 ft (4.57 m) of field-supplied or factory accessory tubing. For proper unit 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 applications.

IMPORTANT: Always install the factory-supplied liquid-line filter drier. If replacing the filter drier, refer to Product Data Digest for appropriate part number. Obtain replacement filter driers from your distributor or branch.

can be no deviation. Consult the Application Guideline and Service Manual – Air Conditioners and Heat Pumps Using Puron Refrigerant to obtain required unit changes for specific applications and for R-22 retrofit.

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 pan. Refer to unit mounting pattern in Fig. 2 to determine base pan size and knockout hole location.

For hurricane tie downs, contact distributor for details and PE Certified (Professional Engineer), if required.

On rooftop applications, mount on level platform or frame. Place unit above a load-bearing wall and isolate unit and tubing set Consult local codes governing rooftop applications.

Roof mounted units exposed to winds above 5 mph may require wind baffles. Consult the Application Guideline and Service Manual - Residential Split System Air Conditioners and Heat Pumps Using Puron Refrigerant for wind baffle construction.

mm/m) per compressor manufacturer specifications.

Clearance Requirements

When installing, allow sufficient space for airflow clearance, wiring, refrigerant piping, and service. Allow 24 in. (610 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 1 side of unit

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

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.
