Thermostat type

If you are planning to convert your ice

 

 

box into a freezer, or as a spillover

 

 

system, a freezer thermostat (0021)

 

 

must be used.

4 Evaporator type & size

If the evaporator has an even coating of

 

 

frost, the thermostat is set on 7, & the

 

 

system is cycling, the evaporator may

 

 

be too small. Either replace the

 

 

evaporator with a larger model, add

 

 

insulation to the bottom of the box to

 

 

reduce volume, or re-locate the

 

 

evaporator lower in the box. The latter

 

 

may cause the temperature at the top of

 

 

the box to be above acceptable levels.

5

Excessive frost build-up

If an excessive layer of frost is allowed

 

 

to build up on the evaporator it will act

 

 

as an insulator & adversely affect box

 

 

temperatures. Defrost system by

 

 

interrupting power supply at the breaker

 

 

panel or by turning thermostat to the off

 

 

position. Restore power or reset

 

 

thermostat when evaporator is free of

 

 

frost. Never use any implement in an

 

 

attempt to loosen the frost on the

 

 

aluminum evaporator. A light frost is

 

 

acceptable.

6

Incorrect refrigerant

If, after the compressor has been

 

charge

running for an appreciable length of

 

 

time, the evaporator surface does not

 

 

have an even coating of frost, or it is

 

 

only cold & sweating to the touch, the

 

 

system may be low on refrigerant or

 

 

over-charged. Consult a marine

 

 

refrigeration specialist.

7

Drain left unplugged

If your ice-box is equipped with a drain

 

 

in the bottom of the box, it is suggested

 

 

that you block it off to prevent heat

 

 

loss. The drain should only be used if

 

 

you revert to melting ice, or after a

 

 

major clean-up.

8

Tubing hole left

The hole that had been drilled to allow

 

unplugged

the copper tubes on the evaporator to

 

 

pass through during installation must be

 

 

sealed.
