Operator Tasks
Before operating the unit, ensure that all compressor
refrigeration service valves are fully back-seated
counterclockwise.
Normal Power Up
The following procedure is used for a startup resulting
from scheduled seasonal or programmed cold shut down
of the chiller/heater.
Important: This start-up procedure is not to be used for
the first-time initial startup for a newly
installed chiller. See Preparation for Initial
Startup in the Installation section of this
manual for instructions regarding that
situation.
1. De-energize the chiller/heater using standard lockout/
tagout procedures.
2. Using a known operational voltage meter, test and
confirm the chiller/heater is de-energized before
proceeding further.
3. Inspect power distribution fuses and overload settings
to verify they are correct.
4. Verify that the oil level is correct in each compressor
using the compressor sight glass.
5. Verify that pressure and temperature switches are
closed.
6. See recommended inspection interval in the
maintenance section of this manual.
7. Restore power to all modules.
8. Verify chiller/heater water flow to condenser and
evaporator.
9. Monitor and record temperature and refrigerant
pressures registering on the touchscreen interface
panel.
10. Inspect refrigerant pressures for each module using
the touchscreen interface panel.

NOTICE
Compressor Damage!
Failure to properly back-seat rotalock valves can cause
compressor failure. Verify the circuit breakers on the
module electrical panel are turned to OFF position prior
to applying power.
WARNING
Hazardous Voltage and Electrical
Capacitor!
Failure to disconnect all power and discharge
capacitors before servicing could result in death or
serious injury. Disconnect all electric power, including
remote disconnects, before servicing.
Follow proper lockout/tagout procedures to ensure that
electrical power cannot be accidentally energized.
Always use PPE and a functional voltmeter when
conducting service in this equipment.
NOTICE
Compressor Damage!
Failure to follow instructions below could result in
catastrophic compressor failure. Do not operate with
