Seasonal Unit Start-Up
Note: The following procedure is
a requirement prior to the first
start of the chiller. Failure to
complete may result in damage
to the compressor and void the
warranty.
1. Close all drain valves, and
reinstall the drain plugs in the
evaporator and condenser
headers.
2. Service the auxiliary
equipment according to the
start-up and maintenance
instructions provided by the
respective equipment
manufacturers.
3. Vent and fill the cooling tower,
if used, as well as the
condenser and piping. At this
point, all air must be removed
from the system (including
each pass). Then close the
vents in the condenser water
boxes.
4. Open all of the valves in the
evaporator chilled water
circuit.

5. If the evaporator was
previously drained, vent and
fill the evaporator and chilled
water circuit. When all air is
removed from the system
(including each pass), close
the vent valves in the
evaporator water boxes.
6. Lubricate the external vane
control linkage as needed.
7. Check the adjustment and
operation of each safety and
operating control.
8. Complete all control settings.
9. Ensure water flows in the
condenser and evaporator are
correct according to the pre-
commissioning procedures.
10. Close all disconnect
switches.
11. Ensure the unit has been
charged with the correct
amount of refrigerant and oil
and that the oil is the proper
operating temperature.
12. Complete a phase rotation
test if the voltage is less than
600 volts.
13. Perform instructions listed in
"Unit Start-up" section
WARNING
Live Electrical
Components!
During installation, testing,
servicing and troubleshooting of
this product, it may be necessary
to work with live electrical
components. Have a qualified
licensed electrician or other
individual who has been properly
trained in handling live electrical
components performs these tasks.
Failure to follow all electrical safety
precautions when exposed to live
electrical components could result
in death or serious injury.
CAUTION
Refrigerant Loss May
Occur:
To avoid excessive unit refrigerant
pressure above the relief valve
setting, follow these
recommended procedures:
• Do not run the pump for more
than 30 minutes after chiller shut-
down.
Failure to avoid excessive
operation of the evaporator
water pump with Chiller off
may cause loss of refrigerant
charge.
• If the chilled water loop is used
for heating.
• Ensure that the evaporator is
isolated from the hot water loop
before changing over to the
heating mode.
