INSTALLATION

I. CHECK EQUIPMENT AND JOB SITE

A. UNPACK UNIT

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

B. 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.

II. 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. 3 to determine base pan size and knockout hole location.

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.

CAUTION: Do not allow POE lubricant to come into contact with roofing material. POE may deteriorate cer- tain types of synthetic roofing.

Roof mounted units exposed to winds above 5 mph may require wind baffles. Consult the Application Guideline and Service Manual for Residential Split System Air Conditioners and Heat Pumps using Puron® Refrigerant for wind baffle construction NOTE: Unit must be level to within ±2 ° (±3/8 in./ft) per compressor manufacturer specifications.

III. CLEARANCE REQUIREMENTS

When installing, allow sufficient space for airflow clearance, wiring, refrigerant piping, and service. Allow 30-in. clearance to service end of unit and 48 in. above unit. For proper airflow, a 6-in. clearance on 1 side of unit and 12 in. on all remaining sides must be maintained. Maintain a distance of 24 in. between units. Position so water, snow, or ice from roof or eaves cannot fall directly on unit.

IV. OPERATING AMBIENTS

The minimum outdoor operating ambient in cooling mode is 55°F, and the maximum outdoor operating ambient in cooling mode is

V. INSTALL TXV

Puron® fan coils and furnace coils come factory equipped with a bi-flow, hard shut off TXV specifically designed for Puron® two-speed units. No TXV changeout is required. An existing R-22

TXV must be replaced with a factory approved TXV specifi- cally designed for Puron® two-speed units.

NOTE: FK4 and FC4 fan coils are equipped with an R-22 TXV. If an FK4 or an FC4 fan coil is used with a Puron® air conditioner, the R-22 TXV must be replaced with a factory-approved Puron® TXV.

→CAUTION: If indoor unit is equipped with piston, remove indoor coil piston and replace with factory

approved TXV metering device.

A. TXV INSTALLATION

IMPORTANT: The TXV should be mounted as close to the indoor coil as possible and in a vertical, upright position. Avoid mounting the inlet tube vertically down. Valve is more susceptible to malfunction due to debris if inlet tube is facing down. A factory approved filter drier must be installed in the liquid line. (See Fig. 4.)
