KW — Maximum Power Input (compressor)
LRA — Locked Rotor Am.ps
MCA — Mm imum Circuit Amps (for wire sizing). Complies with
National Electrical Code (NEC) Section 430-24.
MKW — Unit power input at operating conditions of 50 F Leaving
Chilled Water Temperature (44F Saturated Suction
Temperature) and 120F (FIK) or 145F (HL) Saturated
Discharge Temperature.
MTA — Must Trip Amps (factory-installed circuit breaker)
RLA — Rated Load Amps
START-UP AND SERVICE
WARNING; Shut off all power to unit before
proceeding with any service work.
Initial Check
Do not attempt to start the liquid chiller even
momentarily until the following steps have been
completed.
1. Check all auxiliary components such as chilled
liquid circulating pump, cooling tower if used,
air handling equipment, or other equipment to
which chiller supplies liquid. Consult manu¬
facturer’s instructions.
2. Checksafety thermostat. See Safety Thermostat.
3. Determine if there is a refrigerant charge in the
system. Refer to Check Refrigerant Charge.
4. Backseat (open) compressor suction and dis¬
charge shutoff valves.
5. Open liquid line shutoff valves.
6. Open valves to capillaries of water-regulating
valve (when used).

"Compressors in ai! models have extended voltage motor,
fUnits are suitable for use on electrical systems where voltage
supplied to the unit terminals is not below or above the range
limits shown.
iPrefix: 2=1 electric unloader; C, 7 = 2 electric unloaders.
*"30HK,FIL015 models use 06D compressor instead
of 06E compressors.
7. Fill chilled liquid circuit with clean water or
other noncorrosive fluid to be cooled. Bleed
all air out of high points of system.
8. Open supply valve (or fill cooling tower if used)
for condenser cooling water.
9. Set temperature controller.
10. Check tightness of all electrical connections.
11. Be sure compressor is floating freely on the
isolation springs. See Installation, Step 3.
12. Check compressor oil (should be visible in
bull’s-eye). Refer to Check Oil Charge.
13. Be sure crankcase of each compressor is warm
(heaters should be on for 24 hours before start¬
ing compressors).
