INSTALLATION
PRELIMINARY SURVEY
Before installation is started, a survey should
be made to establish the procedures and ma­
terials
required by installation personnel. See
cover picture for typical unit.
Storage
Because of the sensitive control mechanisms and
electrical
devices incorporated in the 30HH,HJ
units, they should not be exposed to the weather.
Location
Always locate the unit indoors. In order to pre­
vent freezing, the unit must be located in a space
where the temperature is at least 40 degrees.
Space Requirements and Clearance
Dimensions for the units are given in Table 1.
These
dimensions are useful in checking door
clearances for moving the unit in and for deter­
mining space requirements. A clearance of 2 to
3 feet should be left on each side and on the ends
for
piping and electrical connections and also
to facilitate service operations. Clearance at
one end of the unit, equal to the length of the
unit, for servicing and removal of chiller tubes
must be provided.
Adequate Floor Strength
Approximate weights of units are given in Table
1. Make certain that the floor is strong enough
to support this weight. If necessary, add sup­
porting structure to the floor for transferring
weight to the nearest beams. This can be done
with steel beams or reinforced concrete slabs.
Vibration Isolation
Rubber-in-shear vibration insulators and muf­
flers are installed on, or furnished with, the
compressors of all units beginning with early
1961 production. The inter-connecting piping
must be sufficiently flexible to prevent vibra­
tion transmission, if vibration still exists, vi­
bration isolators may be used on the unit itself.
The
field-purchased vibration mountings should
be placed under each corner of the package. The
weight
distribution of all packages except the
30HH015 and 30HJ015 is such that each corner
mounting
supports one fourth of the operating
weight. The weight distribution of the 30HH015
and 30HJ015 units is 55-45 side to side and sym­
metrical front to back.
All phases of vibration isolation are fully de­
scribed in Section 5X-1 of the Product Infor­
mation book. Consult same for best results.
For additional information see "Compressor
Mounting."
MOVING AND PLACING UNIT
Moving
The skids on which the unit is mounted should
not be removed until the unit is at the final loca­
tion. When handling the unit with a chain hoist,
remove the panels so that they will not be dam­
aged by the sling. Do not attach the sling to
