STRUCTURAL SUPPORT AND INSTALLATION
Structural support of the unit must be provided as indi-
cated for maximum efficiency.
Make sure there is enough maintenance space around
the chiller so work can be performed safely.
Foundation bolts should be installed in level concrete
to secure the unit and prevent shifting in the event of
an earthquake. Rubber vibration isolator pads must be
fit to the machine base before installation as shown on
. The tolerance for leveling is 1
inch in 1,000 inches or 1 mm in 1,000 mm according to
the bottom edge of tube plate.
CAUTION: Waterproof the floor on
which the machine will be installed in
case of future leaks.
Dimensions can be found in
For
the external dimensions of the machine and founda-
tion, see the full view of the machine and the founda-
tion drawing.
For serviceability and maintenance, leave a minimum
of 40 inch space on all sides of the chiller. To ensure
there is adequate clearance for tube removal, the main-
tenance space at the end of the unit should equal 1.25 x
the length of the unit.
INDOOR AND OUTDOOR INSTALLATION
This chiller is designed to be used indoors. Exposure to
the elements can compromise the integrity of the ther-
mal insulation. Minimum allowable temperature for
outdoor installation is 32°F, provided that the chiller
includes the cold ambient option. Outdoor installations
will be considered on a case-by-case basis by a Johnson
Controls Service Representative.
ELECTRICAL
The electrical work must be performed in accordance
with the wiring diagrams, delivery specifications, and
technical standards for electrical equipment found in
. Use the specified
cables to complete the wiring, and fasten them to the
according terminals securely. Loose fitting cables can
cause the terminals to heat up, resulting in fire or elec-
trical shock.
CAUTION: The chiller does NOT arrive
with a ground fault (earth leakage) cir-
cuit breaker installed. Be sure to have the
customer install one at the primary side
of the unit.
Electrical work must be supervised or completed by a
Johnson Controls Service Representative.
PRECAUTIONS FOR USE
A caution label for a rotating object is pasted around
the belt cover of the vacuum pump. When replacing
the oil in the vacuum pump, belt, or performing main-
tenance work, stop the chiller and be sure to turn off
the main circuit breaker (MCB1) and lockout or tagout
the unit. If this is not done, the vacuum pump could
start abruptly and cause injury or damage to the unit.
Do not place anything heavy on the machine or its
control panel; it may fall and cause injury.
Do not climb up the machine without safety harnessing.
Contact your local Johnson Controls service office for
inspection and maintenance of the machine. Improper
inspection and maintenance may cause a malfunction
or bodily injury.
Keep the chilled water, cooling water, and hot water
under the maximum usage pressure. If they exceed the
maximum usage pressure, they may spout or leak and
may cause an electric leak and a burn.
Do not change the set values of the safety devices and
protective devices. Operation with incorrect set values
can cause a problem.
The shut off valve for the pressure release valve must
remain open except during servicing. The unit must
never be operated with this shut off valve closed.
A caution label for high temperature is pasted at the
control panel, solution pump, and vacuum pump. Be
sure not to touch the pump during pump operation; it
may cause a burn.
Wear protective gloves and goggles when operating
the control valve, and other parts of the chiller.
CAUTION: During service and mainte-
nance work, be sure to turn OFF the main
circuit breaker (MCB1) and follow all re-
quired Lockout/Tagout procedures. Fully
close the main valve to prevent electric
shock and injury.
