GENERAL

This installation instruction contains basic unit installation information, including installation of thermostats and remote temperature sensors.

For additional information and service instructions, refer to the Controls and Troubleshooting literature also enclosed in this literature packet.

The 48ZT,ZW units are equipped with standard integral economizer and high-capacity power exhaust.

The 48Z6,Z8 units are equipped with factory-installed return/exhaust fans.

The staged gas control (SGC) option adds the capability to control the rooftop unit’s gas heating system to a specified sup- ply air temperature set point for purposes of tempering a cool mixed-air condition.

SAFETY CONSIDERATIONS

Installation and servicing of air-conditioning equipment can be hazardous due to system pressure and electrical compo- nents. Only trained and qualified service personnel should install, repair, or service air-conditioning equipment.

Untrained personnel can perform basic maintenance func- tions of cleaning coils and filters and replacing filters. All other operations should be performed by trained service per- sonnel. 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, including ANSI (American Nation- al Standards Institute) Z223.1. 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. Electrical shock could cause personal injury.

FOR YOUR SAFETY

WHAT TO DO IF YOU SMELL GAS

Do not try to light any appliance. Do not touch any electri- cal switch; do not use any phone in your building. Immedi- ately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions. If you cannot reach your gas supplier, call the fire department.

FOR YOUR SAFETY

Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other appliance.
