Operating Environment

I I m m p p o o r r t t a a n n t t : :
• The standard chiller is designed for
indoor use only and as such has NEMA
Type 1 enclosures.
• For chillers in unheated equipment
rooms, contact your local Trane Service
Agency for methods to ensure that the
oil temperature is maintained suitable
for proper operation of the chiller.

To ensure that electrical components operate properly,
do NOT locate the chiller in an area exposed to dust,
dirt, corrosive fumes, or excessive heat and humidity.
The maximum ambient temperature for chiller
operation is 104°F (40°C).

Foundation Requirements

Chiller mounting surface must be:
• rigid non-warping mounting pads or a concrete
foundation, and
• able to support the chiller at its full operating
weight (including completed piping and full
operating charges of refrigerant, oil, and water).
For proper unit operation, the chiller must be level
within 1/16 in. (1.6 mm) over its length and width when
set into place on the mounting surface.
(lb)," p. 16 and "Weights (kg)," p. 19
approximate weights for various chiller sizes and
options in pounds and kilograms, respectively.
N N o o t t e e : : For specific weight information, refer to the unit
submittal package.
I I m m p p o o r r t t a a n n t t : : Trane will not assume responsibility for
equipment problems resulting from an
improperly designed or constructed
foundation.

Rigging

Lifting is the recommended method for moving
chillers. Suggested lifting arrangements for standard
units are described in "Standard Chiller Lift," p.
N N o o t t e e : : The lifting beam used for CVHE, CVHF, and
CVHG CenTraVac ™ chillers must be at least 16 ft
(4.9 m) long.

Standard Chiller Lift

1. Insert clevis connections at the points indicated in
the following figure. A 2 in. (50.8 mm) diameter
lifting hole is provided at each of these points.
2. Attach the lifting chains or cables.
3. Once the lifting cables are in place, attach a safety
chain or cable between the first-stage casing of the
compressor and the lifting beam.
I I m m p p o o r r t t a a n n t t : : There should NOT be tension on this
safety cable; the cable is used only to
prevent the unit from rolling during the
lift.
