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
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.

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
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.

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
