Table 2-3 Function of parts
Name Function
Operation display panel
Runs and stops the product and performs settings such as the circulating
fluid temperature.
For details, refer to
’’2.4 Operation display panel’’.
Fluid level gauge
Indicates the circulating fluid level of the tank. For details, refer to
“3.5Fill of
circulating fluid
”.
Model label
Shows the product information such as model number and serial number.
For details, refer to
‘’1.4 Product Label’’.
Circulating fluid outlet port The circulating fluid flows out from the outlet port.
Circulating fluid return port The circulating fluid returns to the return port.
Tank drain port This drain port to drain the circulating fluid out of the tank.
Automatic fluid fill port
Piping to the automatic fluid filling port enables easy supply of the circulating
fluid through the ball tap in the reservoir.The supply pressure should be
within the range of 0.2 to 0.5MPa.
Overflow port
Be sure to connect piping from this port to sump pit to discharge the exsess
circulating fluid that caused by fluid level rising.
Dust-proof filter
Inserted to prevent that the dust and contamination are clung on the air
cooled condensers directly. For details, refer to
“8.2.2Monthly check”.
Power cable entry
Insert the power cable to the power cable entry and connect it to the power
terminal. For details, refer to

Earth leakage breaker
(When option B [Earth leakage
breaker]I is selected. Shuts off the power supply to the internal eqipment of product.
(Parts energized remained in the product)
Refer to
“3.3.2Electrical wiring” for the earth leakage breaker.
Facility water inlet port Supply facility water to inlet port.
Facility water outlet port
Facility water out from outlet port and return to customer
’s facility water
system.
Automatic water-fill port
(When automatic fluid filling
[Option J] is selected.)
Piping to the automatic fluid filling port enables easy supply of the circulating
fluid through the built-in solenoid valve.The supply pressure should be in a
range of 0.2 to 0.5MPa.
Overflow port
(When automatic fluid filling
[Option J] is selected.)
This is necessary when automatic fluid filling function.Discharge excess
circulating fluid when the fluid level in the tank rises.
