If outdoor installation is desired, a weather enclosure must be constructed around the unit. UNIT LOCATION Allow sufficient clearance for: 1. Removal of fan shaft and coil. 2. Service of fan motor, bearings, damper motor and linkage (at least 30 inches) 3. Unit air supply (minimum distance of 4 feet from ceiling, wall, or floor when supplied from one side only). PRE-INSTALLATION 1 File claim with shipping company if shipment is damaged or incomplete. 2. Examine unit nameplate to verify that electrical requirements match available power supply. 3. Rotate fans by hand. Check for freedom of rotation and secureness to fan shaft. 4. Remove shipping straps from skid and unit. INSTALLATION Observe the following- 1. When rigging, do not support unit weight by fan shaft extension or coil connections Put rigging medium completely around unit, using spreader bars to ensure that sling lifts at the skid without touching the unit sides. 2. Remove coil piping connection protective caps only when ready to connect piping. 3. Exercise reasonable care not to bend or mutilate coil fins. 4. On bypass units, where bypass is not desired, block off opening with a strip of sheet metal (field-supplied) and secure. Unit Mounting (Fig. 1 and Table 1) HORIZONTAL ARRANGEMENT (Standard) 1 Remove plug buttons covering captive nuts used to fasten suspension clips.

Bolt suspension clips (supplied), one near each corner of fan section and one near each end of coil section. Tighten bolts (supplied) securely. 3. Lift unit into position. 4. Pass threaded hanger rod (field-supplied) thru each suspension clip. 5. Fasten with nuts (field-supplied). VERTICAL ARRANGEMENT 1. Bolt legs (accessory) to inlet side of coil section, using 5/8 in. - 11 captive nuts (located on inward flanges of coil section) and bolts (supplied). Tighten securely. 2. Rotate motor end bells 90 degrees so drain holes are at bottom. Rotating end bells must be performed by an authorized vendor’s motor repair shop. Refrigerant Piping GENERAL — All field leak and pressure testing should be in accordance with local code requirements. If no local code exists, use American Standard Safety Code for Mechanical Refrigeration (A.S.A. B9.1). For leak testing procedures, refer to the Carrier Standard Service Techniques Manual, Chapter 1, Section 1-6. Refrigerant line sizing depends on length of lines between various sections of the refrigerant HANGER RODS(6) HOT GAS RISER A80VE REFRiG LEVEL IN COND CIRCUIT ON LONG, HOT GAS LINES INSTALL A TRAP * t COMPRESSOR system. Consider the amount of liquid lift and drop in the system as well as proper compressor oil return. Consult Carrier System Design Manual, Part 3, for proper piping sizes and design. Liquid and hot gas connections for any one split are same size so coil may be reversed for opposite-hand connection, but must be piped for counter flow in any case. LIQUID SHUT-OFF VALVE AND SIGHT GLASS — Shut-off valve is not supplied with units. It is strongly recommended that a full line size liquid shut-off valve be field supplied near condenser to allow for servicing parts of the refrigerant circuit. A field-supplied, moisture-indicating sight glass is recommended for use in charging and servicing the system. Refer to Fig. 2 for location. The American Standard Safety Code for Mechanical Refrigeration (A.S.A. B9.1, 1964, paragraph 12.1) states as follows: “Every refrigerating system shall be protected by a pressure relief device unless so constructed that the pressures due to fire conditions will be safely relieved by some part of the system.” Since the 09FA units have no pressure relief device, it should be field supplied and installed.
