Section 4 – Installation and Startup
4.1 Site Requirements
4.1.1 Ambient Temperature and Relative Humidity
The Chiller is designed for indoor installation in ambient temperatures between 14° and 104°F (-10° to 40°C); relative
humidity should be between 20% and 80% (non-condensing).
4.1.2 Location
The Chiller should be installed on a level surface capable of supporting 990 pounds (449 kg) or more and should be
located as close to possible to the process requiring cooling. It should not be installed closer than 4 feet (1.4 meters)
to a heat generating source, such as heating pipes, boilers, etc.). If possible, it should be located near a suitable drain
to prevent flooding in the event of leaks.
For ease of final positioning and maneuverability, the Chiller is supplied with four heavy-duty locking casters. Use
fork lift if moving more than 20 feet.
4.1.3 Clearance
At least 18 to 24 inches (45.7 to 61 cm) of clearance should be allowed on the front, sides, and rear of the Chiller for
access to connections and components. Chillers require at least 4 feet (1.4 meters) of overhead clearance to
dissipate the exhaust from the Chiller’s top-mounted fan.
4.2 Plumbing
See Figure 4-1
4.2.1 Process Piping
The Chiller incorporates two 1/2” MPT x ¾”- 16 male 37 ° flare, #8 JIC fittings on the rear of the enclosure for the
process inlet and outlet connections.
To maintain a safe workplace and to avoid leaks, special care should be taken when choosing hoses and
connections for the Chiller.
•
Pressure Ratings — Hoses should be able to withstand a minimum of 250 PSI.
•
Flexible Tubing — Avoid tubing that will expand and take up fluid volume when operating at the desired
pressure.
