SAFETY PRECAUTIONS
1-1-3.Operating precautions
①
Keep the purge valve shut tightly to prevent air from leaking into the Chiller, which may
cause the failure of the Chiller.
②
Keep to turn on the power supply to the control panel without maintenance service.
③
During the dilution cycle operation of the Chiller as well, the chilled water pump (both the
primary side and the secondary side) and air handling unit must be operated for the necessary
time. The Chiller has a little cooling capacity even if it is in the dilution cycle operation.
Do not stop the air handling unit before the necessary time to prevent possible subcooling.
④
Do not perform an insulation test on the control circuits of the electric controller.
⑤
Use Carries recommended interlock system for stop/start of the auxiliary equipment.
The interlock system automatically stops/starts chilled water pump and cooling water pump.
Please follow the start procedure in Figure 1-1 below.
