I.  Evaporator options:

1.  Provide 1-1/2”” evaporator insulation in lieu of standard 3/4”.

J.  Hot Gas By-Pass: Permits continuous, stable operation at capacities below the mini-

mum step of unloading to as low as 5% capacity (depending on both the unit & operat-

ing conditions) by introducing an artificial load on the evaporator. Hot gas by-pass is 

installed on only one refrigerant circuit.

K. Thermal Storage: leaving chilled liquid setpoint range for charge cycle from 25°F to 

20°F minimum, with automatic reset of the leaving brine temperature up to 40°F above 

the setpoint. 

L.  Low Temperature Process Glycol: leaving chilled liquid setpoint range 10°F to 50°F 

(-12°C to 10°C)

M. Chicago Code Relief Valves to meet Chicago Code requirements.

N. Sound Reduction (Factory installed):

O. Vibration Isolation (Field installed):

1.  Elastomeric Isolators.

2. 

1” Deflection Spring Isolators: level adjustable, spring and cage type isolators for 

mounting under the unit base rails.

3. 

2” Deflection Restrained Spring Isolators: level adjustable, restrained mounts in rug

-

ged welded steel housing with vertical and horizontal limit stops. Housings shall be 

designed to withstand a minimum 1.0g accelerated force in all directions to 2 inches 

(50.8 mm).

PART 3 – EXECUTION

3.01 INSTALLATION

A. General: rig and install in full accordance with manufacturer’s requirements, project 

drawings, and contract documents.

B. Location: locate chiller as indicated on drawings, including cleaning and service main-

tenance clearance per manufacturer instructions. Adjust and level chiller on support 

structure.

C. Components: installing contractor shall provide and install all auxiliary devices and ac-

cessories for fully operational chiller.

D. Electrical: coordinate electrical requirements and connections for all power feeds with 

electrical contractor (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.
