q Heat shrinkage tube
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.

4.2.13 Air-cooled condenser and evaporator

This finned coil is compact and has uniform
heat exchanging performance and high heat
exchanging efficiency due to the adoption of
corrugated fins.
● Washing of air-cooled condenser
Carefully flush the air-cooled condenser with
fresh water after trip, although this type of
condenser employs thick fins and
electrodeposition coating for high corrosion
resistance.
● For the maintenance of the air-cooled
condenser, remove the fan grille, fan guide
and temperature recorder box. For the
maintenance of the evaporator, remove the
rear panel of the evaporator.

4.2.14 Fusible plug

Receiver
Fusible plug
● Replacement of fusible plug
If pressure rises abnormally in the refrigeration
circuit, the fusible plug is automatically
activated, so, thoroughly check the possible
causes if the fusible plug melts.
If the fusible plug is activated, the fusible alloy
q melts and refrigerant blow out (Melting
point: 95˚C ~100˚C).
For replacement, q-e shall be replaced.
