Frigodrink Service manual - Ugolini

ARCTIC COMPACT & DELUXE
1 INTRODUCTION
Like all mechanical products, this machine will require cleaning
and maintenance.
This Service Manual contains maintenance guidelines
dedicated to qualified service personnel only.
2 TEMPERATURE CONTROLS
IMPORTANT
Rotating the setting screw of the thermostats completely
counterclockwise it is possible to switch off the
thermostat itself. This will stop the refrigeration only on
single bowl units. On multiple bowls units it is necessary
to switch all the thermostats off in order to stop the
refrigeration.
All the units with12 or 20 litres bowls, both Deluxe and Compact
series, are equipped with one adjustable thermostat for each
bowl. The thermostats are located behind the panel under each
bowl (see figure 1).
IMPORTANT
On multiple bowls units the thermostats are electrically
wired in parallel and they directly drive the compressor.
It is necessary that all the bowls reach the set
temperature to stop the refrigeration (all the thermostats
electrically open). It is enough that only in one bowl the
temperature is higher than the setting to start the
refrigeration (only one thermostat electrically closed).
To adjust temperature on multiple bowls machines it is
necessary to adjust all the thermostats together at the
same setting.
On multiple bowls units independent temperature
adjustment for each bowl is not available.
For Artic Compact 5 and 8 series the situation is the following:
figure 1
It is possible to adjust temperature between 6 °C and 12 °C. On
new machines the temperature is factory preset approx at 8°C.
For temperature adjustment proceed as follows:
- to decrease temperature: rotate the setting screw clockwise.
- to increase temperature: rotate the setting screw
counterclockwise (see figure 2).
Arctic Compact 5-8/1 are equipped with one thermostat to
control the themperature of the bowl.
Arctic Compact 5-8/2 are equipped only with one thermostat to
control the temperature of the bowl at the right.
Arctic Compact 5-8/3 are equipped only with one thermostat to
control the temperature of the central bowl.
Arctic Compact 5-8/4 are equipped with two thermostats to
control the temperature of the first and the third bowl from right.
The thermostats are always located behind the faucet side
panel under the coresponding bowl.
This means that the refrigeration on and off depend from the
setting of the temperature only of the bowls equipped with the
thermostats.
It is possible to set the temperature between 6 °C and 12 °C. On
new machines the temperature is factory preset approx at 8°C.
For temperature adjustment proceed as follows:
- to decrease temperature: rotate the setting screw clockwise.
- to increase temperature: rotate the setting screw
counterclockwise (see figure 2)
Independent temperature setting for each bowl is not possible.
The following table summarizes the number of thermostats
present on each model:
