Location -To ensure unit operates at maximum efficiencies,
choose a dry indoor area where the temperature is controlled
between 50 deg F and 115deg F. Consideration of surround-
ing areas should be taken when choosing a location to install
the unit. Common vibration and sound levels associated with
commercial equipment may be objectionable to people or
equipment. Install thermostats, air supplies and returns so
that each unit will operate only on individual unit control.
UNIT MOUNTING
The 5 through 25 ton models are shipped as a fully assem-
bled integral package. The 5-15 ton units may be field split
between the evaporator/compressor section and the upper
blower section; to allow for passage through doors, elevators,
hallways, etc. Units are not intended for outdoor installation.
Floor mounted units should be secured on a solid, level sur-
face or sturdy stand. (refer to typical installation diagram on
Page 4). The use of an isolating rubber sheet is recom-
mended to reduce vibration and noise transmission. Ensure
that the entire base is continuosly supported -do not support
unit at corner points only!
GENERAL DATA
TABLE 1: GENERAL UNIT INFORMATION
Note: The water cooled coaxial condensers in these units
have copper tubing and are NOT suitable for salt or brackish
water. Do not install these units outdoors, or in any area
where the surrounding temperature may drop below 32
degrees F.
LOCK ALL ELECTRICAL POWER SUPPLY
SWITCHES IN THE OFF POSITION BEFORE
