Mermaid REFRIGERATION/FREEZER installation instructions System Runs, Box Temperature Too Low

Page 15

E: System Runs, Box Temperature Too Low:

1

Thermostat setting

Rotate thermostat knob to a lower

 

 

number.

2

Thermostat type

Check that you are using a refrigerator

 

 

thermostat (0028) for a refrigerator

 

 

application.

3

Faulty thermostat

If system is running continuously &

 

 

box temperatures are too low with

 

 

thermostat set on the lowest number,

 

 

first check for correct thermostat

 

 

connections at the Module, then remove

 

 

one connection. If compressor stops,

 

 

turn off breaker, replace connection &

 

 

then control system manually from the

 

 

breaker until the thermostat can be

 

 

replaced.

4

Holding plate over-sized

If you are using a holding plate

 

 

evaporator that is over-sized for the

 

 

application, it will absorb more heat

 

 

than that which enters the box through

 

 

the insulation, & so lowers the

 

 

temperature. Experiment by covering

 

 

some of the plate surface with

 

 

insulating material until you achieve

 

 

correct box temperatures. This method

 

 

will also increase hold-over times.

5 Poor spillover system

If you are running the evaporator as a

construction

freezer, & cooling an adjoining

 

refrigerator compartment with some

 

spillover air, there must be an adequate

 

thermal barrier between the two, & it

 

must be properly sealed to prevent

 

unwanted air-flow. Temperatures in the

 

refrigerator side should be controlled

 

either with trial-&-error convection

 

holes, or a thermostatically controlled

 

fan. Two apertures are necessary, one

 

high & one low for adequate air

 

circulation.
