4. DEHUMIDIFICATION CONTROL SETTING
This unit features the dehumidification function. Therefore, it is necessary to set whether the
dehumidification control is to be executed or not according to the cargo to be transferred.
You can set whether the dehumidification control is to be executed or not by operating the display
panel of controller.
4.1 Description of setting
Whether the dehumidification control is to be executed or not is switched over according to the setting
of dehumidification control parameter "dHu" under the "4. G-SET operation / Automatic pump down
operation mode / Dehumidification ON-A･OFF setting"
CAUTION
1．ON/OFF of the reheating coil and DE-HUMID LED lit/unlit are not
synchronous.
2．To apply the humidification control, be sure to set "ON-A".

CAUTION
Do not expose the low pressure
transducer to hot air of a dryer for
excess time.
Otherwise, the transducer may be damaged.
7.1 Low pressure transducer (LPT)
The LPT is located in the refrigerant circuit.
The operating low pressure value is displayed
on the controller indication panel.
(1) Replacing the transducer
q Disconnect the lead wire from the control box.
w In order to prevent refrigerant from flowing
out, disconnect the low-pressure transducer
piping from the gauge joint (with check valve)
C on the compressor side.
e Remove two screws on the clamp plate fixing
low pressure transducer in place, and cut the
binding bands.
tInsert the pressure transducer cable through
the heat shrinkage tube, and connect the
union joint and connector to the new low
pressure transducer. If paint on the low
pressure transducer is peeled off, apply clear
lacquer.
rRemove the heat shrinkage tube, and
disconnect the connector from the low
pressure transducer.

The replacement procedure is the same as
that for the low pressure transducer.
Make sure that the fixing position and the
cable connection is correct.
yApply the heat shrinkage tube in the following
position, then shrink it with hot air of a dryer.
uApply sealer between the heat shrinkage tube
and the flare nut. (Sealer :KE4898)
iFix the low pressure transducer with the
clamp plate, and fix the cable with the binding
band.
Fix the shrinkage tube end of the cable side
downward for prevention of water entering
into the tube.
