Unit Start Up Procedures
Temporary Shutdown and Restart
Temporary Shutdown is used for control operation,
maintenance or to repair the unit typically less than one
week.
To shut the unit down for a short time, use the following
procedure:
1. Press the STOP key on the TD7. The compressors
will continue to operate and, after unloading for
20 seconds, will stop when the compressor contactors
de-energize.
2. Stop the water circulation by turning off the chilled
water pump at least one minute after the stop of the
compressors.
To restart the unit after a temporary shutdown, enable the
chilled-water pump and press the AUTO key.
The unit will start normally, provided the following
conditions exist:
• The UC800 receives a call for cooling and the
differential-to-start is above the set point
• All system operating interlocks and safety circuits are
satisfied
CAUTION!
Under freezing conditions, the chilled water pump
must remain in operation during the full shutdown period of
the chiller if the chilled water loop does not contain glycol,
to prevent any risk of evaporator freeze-up. Refer to charts 1
and 2.
Extended Shutdown Procedure
The following procedure is to be followed if the system is to
be taken out of service for an extended period of time (i.e.
seasonal shutdown):
1. Test the unit for refrigerant leaks and repair as necessary
2. Open the electrical disconnect switches for the chilled-
water pump. Lock the switches in the “OPEN” position.
3. Close all chilled-water supply valves. Drain the water
from the evaporator.
4. Open the unit main electrical disconnect and unit-
mounted disconnect (if installed) and lock in the “OPEN”
position.
5. At least every three months (quarterly), check the
refrigerant pressure in the unit to verify the refrigerant
charge integrity.
CAUTION!
Lock the chilled-water pump disconnects open
to prevent pump damage. Lock the disconnect switch in
the “OPEN” position to prevent accidental startup and
damage to the system when it has been set up for extended
shutdown.
During an extended shutdown period, especially over the
winter season, the evaporator and free cooling circuits
must be drained of water, if the chilled water loop does not
contain glycol, to prevent any risk of evaporator freeze-up.
