Re-issue of manual for minor clarity issues; provides specific installation, operation and maintenance instructions for “3” and later design sequence on S_HF units and "W" and later design sequence on S_HG units with constant volume (CV) or variable air volume (VAV) controls.

SXH_-IOM-9 (June 2002)

Original issue of manual; provides specific installation, op- eration and maintenance instructions for “3” and later design sequence on S_HF units and "W" and later design sequence on S_HG units with constant volume (CV) or variable air vol- ume (VAV) controls.

These units are equipped with electronic Unit Control Mod- ules (UCM) which provides operating functions that are sig- nificantly different than conventional units. Refer to the "Start- Up" and "Test Mode" procedures within this Installation, Op- eration, & Maintenance manual and the latest edition of the appropriate programming manual for CV or VAV applications before attempting to operate or service this equipment.

Note: The procedures discussed in this manual should only be performed by qualified, experienced HVAC technicians.

Overview of Manual

This booklet describes proper installation, start-up, opera- tion, and maintenance procedures for 20 through 130 Ton rooftop air conditioners designed for Constant Volume (CV) and Variable Air Volume (VAV) applications. By carefully re- viewing the information within this manual and following the instructions, the risk of improper operation and/or component damage will be minimized.

Note: One copy of the appropriate service literature ships inside the control panel of each unit.

It is important that periodic maintenance be performed to help assure trouble free operation. Should equipment failure occur, contact a qualified service organization with qualified, experi- enced HVAC technicians to properly diagnose and repair this equipment.

Note: Do Not release refrigerant to the atmosphere! If adding or removing refrigerant is required, the service technician must comply with all federal, state, and local laws.
