4.2.4 Electronic expansion valve

●

Model   Coil : HCM-MD12DM-1

Body : HCM-BD35DM-1

This unit adopts an electronic expansion valve.
The electronic expansion valve controls the
optimum refrigerant flow rate automatically,
using the temperature sensor at the evaporator
inlet and outlet pipes.
In case of emergency including controller
malfunctions, refer to the chapter of
troubleshooting, section 6.5, Emergency
operation.

(1) Replacing the coil

q

Remove the binding band fixing the coil lead
wire.

w

Disconnect the connector of the coil.

e

Remove the metal fitting and the coil.

r

Replace the old coil with a new one.

t

Attach the coil and the metal fitting.

y

Mount the connector of the coil.

u

Fix the coil lead wire with a binding band.

(2) Replacing the body

q

Remove the binding band fixing the coil lead
wire.

w

Detach the anti-condensation tube until the
curved part of the pipe.

e

Remove the metal fitting and the coil.

r

Remove the brazed part of the pipe.

t

Insert the new valve body in the pipe.

→

Braze the new valve body while cooling it
with a wet cloth.
Cooling temperature: 120˚C (248˚F) or less

y

Mount the coil and the metal fitting.

u

Mount the anti-condensation tube.

i

Fix the coil lead wire with a binding band.

Attention (When installing the coil
and the metal fitting)

●

Securely attach the coil stopper to the valve
body fixing pipe.

→

If wrongly attached, the expansion valve
may function abnormally, damaging the
compressor.

●

Take care not to allow the metal fitting
damage or pinch the lead wire.

→

Malfunction of the expansion valve may
arise.
