contact with any electrical component either inside or outside the ice-box. If the sensing
tube needs to be bent within the confines of the refrigerator or freezer box, it must be
done with great care, heeding the warnings above.
C: Operation:
The thermostat knob is marked from 1 to 7. The coldest setting is 7, & from this position
the knob can be rotated counter-clockwise to setting 1, which is the warmest. If the knob
is rotated further counter-clockwise, beyond setting 1, some initial resistance is felt &
then the thermostat will click into the OFF position. On initial system start-up, it is
recommended that you set the thermostat to number 4 & let the system run through a few
cycles while monitoring box temperature before any adjustments are made.
TEMPERATURE RANGES FOR EACH MODEL THERMOSTAT
MODEL WARM IN/OUT MIDDLE IN/OUT COLD IN/OUT
FRIDGE ONLY 51.7/40.9 44.5/32 36.4/23.9

Temperatures above are in Fahrenheit and are a range from warmest to coldest. The “in”
temperature is when the unit will turn on during that setting. The “out” is the temperature
when the unit will turn off during that setting. The temperature is measured by the silver
capillary sensing tube on the thermostat. Each thermostat is stamped with the model
number indicating the thermostat range. See below:

A: Note:
Each component of the Mermaid condensing system is fitted with one male & one female
Quick Connect fitting that connects with a corresponding fitting on other components of
the system. The individual items (condenser and evaporator) are charged with the correct
amount of refrigerant at the factory, & when the Quick Connect fittings are joined
