2. Unit should be positioned so Roof-Run-Off water does not pour directly on unit. Page 6 3. 3. 4. Exhaust vents or other sources of contaminated air should not be near unit air inlet if outside air is to be introduced as a make-up air or the economizer ventilation feature is to be used. 5. Check the handling facilities to insure the safety of personnel and the unit(s). 6. CAUTION MUST BE TAKEN AT ALL TIMES TO AVOID PERSONAL INJURIES AND/OR DAMAGE TO EQUIPMENT. 7. The unit must be mounted level for proper drainage of defrost water through the holes in the base pan. 8. Flexible duct connectors must be of a flame retardant material. All duct work outside of the structure must be insulated and weatherproofed in accordance with local codes. 9. Roof flashing must be installed to seal the roof curb cavity and must conform to local building codes. 10. Holes through exterior walls must be sealed in accordance with local codes. 11. Access and service clearances for the unit must be given careful consideration when locating the duct entrance openings. Figures 6 and 8 provide unit dimensions. 12. All fabricated outdoor ducts should be as short as possible. 13. Be sure the hole in the structure for the ducts is large enough to accommodate the fabricated ducts and the insulation surrounding them. (See Figure 6.) CLEARANCES 1. The recommended clearances for single-unit installations are illustrated in Figures 5 and 6. These minimum requirements are not only an important consideration when determining unit placement, but they are also essential to ensure adequate serviceability, maximum capacity, and peak operating efficiency. 2. Any reduction of the unit clearances indicated in this illustration may result in condenser coil starvation, or the recirculation of warm condenser air. Actual clearances which appear to be inadequate should be reviewed with a local sales engineer. IMPORTANT!: To convert to downflow remove covers from the downflow supply and return air openings and place them over the horizontal supply and return air openings (painted side out) and secure with sheet metal screws. INSTALLATION UNIT SUPPORT If unit is to be roof mounted, check building codes for weight distribution requirements. Refer to accessory roof curb mounting instructions. Check unit nameplate for supply voltage required. Determine if adequate electrical power is available. Refer to specification sheet. LOCATION AND CLEARANCES Installation of the unit should conform to local building codes or, in the absence of local codes, to the ANSI/NFPA No. 70-1987 National Electrical Code or “Latest Revision.” Canadian installations must conform to CSA and local codes. Select a location that will permit unobstructed airflow into the condenser coil and away from the fan discharge and permit unobstructed service access into the compressor compartment. Suggested airflow clearances and service clearances are given in Figure 5. PLACING AND RIGGING 1. Before preparing the unit for lifting, check the outline drawing for center of gravity for lifting safety. Because of placement of internal components, the unit weight may be unevenly distributed . Approximate unit weights are given in outline drawing on page 3. NOTE: Accessory BAYLIFT002A Four (A) lifting lugs are recommended for rigging the unit for hoisting. See Figure 7 insert “B”. 2. Insert the four lifting lugs in openings provided in drip lip on perimeter of unit. See Figure 7 insert “B”. 3. Before hoisting the unit, be sure that the proper method of rigging is used, with straps or slings and spreader bars for protection during lifting. IMPORTANT!: DO NOT LIFT THE UNIT WITHOUT TESTLIFTING FOR BALANCE AND RIGGING.DO NOT LIFT THE UNIT IN WINDY CONDITIONS OR ABOVE PERSONNEL. DO NOT LIFT THE UNIT BY ATTACHING A CLEVIS, HOOKS, PINS OR BOLTS TO THE UNIT CASING, CASING HARDWARE, ANGLES, TABS OR FLANGES. FAILURE TO OBSERVE THESE WARNINGS MAY RESULT IN EQUIPMENT DAMAGE. 4. When the curb and air ducts have been properly installed, the unit is ready to be hoisted to the roof and set in position. IMPORTANT!: “Spreader Bars” must be used when hoisting unit. 5. IMPORTANT: The unit must be lowered into position P.V.C. rubber tape on the curb flange permits the unit to be repositioned if required without destroying the P.V.C. rubber seals affixed to mounting curb. 6. PLACING UNIT ON MOUNTING CURB—The unit is designed with a perimeter drip lip that is lower than the unit base ban, see Figure 7 insert “A”. 7. Position the unit drip lip down over and in contact with the outside corner of the curb, as illustrated in Figure 7 insert “A”. Continue to lower unit on top of curb, with the unit drip lip astraddle and in contact with both the end and side rail of curb, the unit is now resting on top of curb. 8. Take the two (2) hold down brackets shipped with curb and secure unit to curb with hold down brackets as illustrated in Figure 8 insert “A”.
