Installation and Startup
WARNING: Be sure all power is OFF before proceeding.
Site Requirements
Ambient Temperature and Relative Humidity
The Chiller is designed for indoor installation in ambient temperatures between 60° and 104°F (16° and 40°C);
relative humidity should not exceed 80% (non-condensing).
Location
The Chiller should be installed on a strong, level surface capable of supporting 1050 lbs. / 476.3 kg (5 and 7.5
HP units) or 1500 lbs. / 680.1 kg (10 HP units).
It should be located as close to possible to the process requiring cooling and installed no closer than 4 feet (1.4
meters) to a heat-generating source, such as heating pipes, boilers, etc. If possible, the Chiller should be
located near a suitable drain to prevent flooding in the event of leaks. Do not place it where corrosive fumes,
excessive moisture, excessive dust, or high room temperatures are present.
For ease of positioning and maneuverability, the Chiller is supplied with casters. The front wheels can be locked
to keep the Chiller in place while in use.
To help prevent voltage drops, position the Chiller as close as possible to the power distribution panel. Avoid
voltage drops by using a properly grounded power source wired to meet electrical data plate requirements. The
use of an extension cord is not recommended.
NOTE: The Chiller may be located at a level below that of the equipment being cooled. As long as the
process remains closed, overflow will not occur when adding cooling fluid to the Chiller reservoir.
Clearance
Adequate clearance should be allowed on the front, sides, and rear of the Chiller for access to connections and
components. The front and rear vents of the Chiller must be a minimum of 24 inches (61 cm) away from walls or
vertical surfaces so air flow is not restricted.
