CAUTION
Do not expose the low pressure
transducer to hot air of a dryer for
excess time.
Otherwise, the transducer may be damaged.
6.1 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.
t
Insert 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.
r
Remove the heat shrinkage tube, and
disconnect the connector from the low
pressure transducer.

6.2 High pressure transducer (HPT)
The HPT is located in the refrigerant circuit.
The operating high pressure value is displayed
on the controller indication panel.
(1) Replacement procedure
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.
y
Apply the heat shrinkage tube in the
following position, then shrink it with hot air
of a dryer.
u
Apply sealer between the heat shrinkage tube
and the flare nut. (Sealer :KE4898)
i
Fix 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.
