Fig. 1 — Dimensions and Connections Carrier Corporation 1983 Form 40FS-11 SI 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 extinguisher available for all brazing operations. WARNING: Before performing service or maintenance operations on unit, turn off main power switch to unit. Turn olT accessory heater power switeli if applicable, electrical shock could cause personal injury. MODULAR SYSTEM INTRODUCTION Field assemble the required 28 Series direct-expansion (encased) coil and/or 40FS,40FQ,38HQ accessory electric heater to 40FS fan section. Combine fan section and coil for a split system fan coil; fan section and accessory electric heater for an electric furnace; fan section, coil and electric heater for a heating and cooling unit.
