Machine Room Temperature and Ventilation -
Locate compressor or condensing unit in well
ventilated space. Check code requirements. Pro­
vide forced ventilation thru ductwork when natural
ventilation is inadequate.
Protect water-cooled condensers, water lines,
and accessories from freezing during winter
shutdown periods.
PREPARE FOUNDATION
Fasten compressor to: (a) steel base and vibra­
tion isolators on floor; (b) steel base and condenser
support stand or (c) concrete base.
Floor Foundations - Locate compressors over
joists or beams wherever possible.
Weak floors in old buildings must be reinforced
with steel beams or timbers to support the heavy
compressors
or condensing units. Use care in
placing supports to avoid transmitting objection­
able vibrations to other areas.
Concrete Foundations one to two times the weight
of the machinery they support will absorb vibra­
tion. See Fig. 8 and Tables 7 and 8 for recom­
mended dimensions. Let foundation set sufficiently
before
compressor is installed (approximately 3
days). Allow for 3/8 inch to 1/2 inch grout after
compressor is installed.
Heavy aggregate concrete weighs about 150
pounds per cubic foot.
INSPECT UNIT
Inspect shipment for damage or loss. File
claim immediately with shipping company for any
loss or damage.
Move and rig unit carefully to prevent damage
to gages, mounting brackets, refrigerant piping
and connections.
COMPRESSOR INSTALLATION
Compressor on Steel Base and Vibration Isolators
on Floor — Install vibration isolators on one end of
unit at a time. See Fig. 9 for typical vibration
isolator mounting.
Motor fastening set supplied with all com­
pressors (except 5F20,30) includes several beveled
washers.
Washers are installed under heads of
capscrews used to fasten unit base to vibration
isolators or floor.
Position compressor and motor on frame and
check height of vibration isolators. Shim between
vibration isolators and floor to level compressor
base Secure vibration isolators to floor. If beveled
washer (Fig. 9) is omitted, end of capscrew may
strike the floor and cause vibration isolator to
rupture when it is secured to floor.
Condenser and Stand Assembly - Place cast iron
condenser stands in their correct location. Make
distance ”C" (Fig. 10) between tapped holes on
top of stand equal to holes in lower flange of com­
pressor unit base. See Table 9 for dimensions.
Shipping caps are soldered to the 5F20,30,40
and 60 condensers at the factory. To remove caps
turn condensers upside down. This prevents solder
from falling into condensers.
Bolt lower support strap loosely to lower side
of each condenser stand.
Place condenser on stands with front water
head at compressor end of base. Position con-
