CL-1 SAFETY CONSIDERATIONS Installation and servicing of air-conditioning equipment can be hazardous due to system pressure and electrical components. Only trained and qualified service personnel should install, repair, or service air-conditioning equipment. Untrained personnel can perform basic maintenance functions of cleaning coils and filters and replacing filters. All other operations should be performed by trained service personnel. When working on air-conditioning equipment, observe precautions in the literature, tags and labels attached to the unit, and other safety precautions that may apply. Follow all safety codes. Wear safety glasses and work gloves. Use quenching cloth for unbrazing operations. Have fire extinguishers available for all brazing operations. CAUTION: Ensure voltage listed on unit data plate agrees with electrical supply provided for the unit. Cancels: II 580F-90-2 II 580F-90-3 2/1/04 WARNING: Disconnect gas piping from unit when leak testing at pressure greater than 1/2 psig. Pressures greater than 1/2 psig will cause gas valve damage resulting in hazardous condition. If gas valve is ever subjected to pressure greater than 1/2 psig, it must be replaced before use. When pressure testing field- supplied gas piping at pressures of 1/2 psig or less, a unit connected to such piping must be isolated by manually closing the gas valve(s). WARNING: Before performing service or maintenance operations on unit, turn off main power switch to unit and install lockout tag. Electrical shock could cause personal injury. INSTALLATION Unit is shipped in the vertical discharge configuration. To convert to horizontal configuration, remove screws from side duct opening covers and remove covers. Using the same screws, install covers on vertical duct openings with the insulation side down. Seals around duct openings must be tight. See Fig. 2. Confirm before installation of unit that voltage, amperage and circuit protection requirements listed on unit data plate agree with power supply provided. I. STEP 1 — PROVIDE UNIT SUPPORT A. Roof Curb Assemble and install accessory roof curb in accordance with instructions shipped with curb. See Fig. 3. Install insulation, cant strips, roofing felt, and counter flashing as shown. Duct- work must be attached to curb. If gas or electrical connections are to be routed through the curb, attach the accessory thruthe- curb service connection plate to the roof curb in accordance with the accessory installation instructions. Connections must be installed before unit is set on roof curb. IMPORTANT: The gasketing of the unit to the roof curb is critical for a watertight seal. Install gasket supplied with the roof curb as shown in Fig. 3. Improperly applied gasket can also result in air or water leaks and poor unit performance. Curb should be level. Unit leveling tolerances are shown in Fig. 4. This is necessary for unit drain to function properly. Refer to Accessory Roof Curb Installation Instructions for additional information as required. If gas or electrical connections are to be routed through the bottom of the unit, attach accessory thru-the-bottom service connections to the base...
