● 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.

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.
