water sensors, and liquid line components (solenoid valves, filter driers, sight glasses, and TXVs), as discrete elements of a complete factory system. Contractor shall be field erect system and provide interconnecting refrigerant piping and wiring in accordance with Manufacturer recommendations, and project plans and schedules. Where not oth- erwise specified, Contractor provided system piping shall be in accordance with applicable sections of ASHRAE Handbook.

O.Hot Gas By-Pass: Permits continuous, stable op- eration at capacities below the minimum step of unloading to as low as 5% capacity (depending on both the unit & operating conditions) by introducing an artificial load on the cooler. Hot gas by-pass is installed on only one refrigerant circuit (System #1).

PART 3 - EXECUTION

3.01INSTALLATION

A.General: Rig and Install in full accordance with Manufacturers requirements, Project drawings, and Contract documents.

B.Location: Locate chiller as indicated on drawings, including cleaning and service maintenance clear- ance per Manufacturer instructions. Adjust and level chiller on support structure. If equipment provided exceeds height of scheduled chiller, installing con- tractor is responsible for additional costs associated with extending the height of parapet or screening walls/enclosures

C.Components: Installing Contractor shall provide and install all auxiliary devices and accessories for fully operational chiller.

D.Electrical: Coordinate electrical requirements and connections for all power feeds with Electrical Con- tractor (Division 16).

E.Controls: Coordinate all control requirements and connections with Controls Contractor.

F.Finish: Installing Contractor shall paint damaged and abraded factory finish with touch-up paint matching factory finish.
