The control thermostat for adjustment of the LR to the
recommended temperature is located between 2
indicator lamps on the front panel. This has settings
from 1 to MAX (maximum). To change the thermostat
setting, its knob can be turned by means of a coin
inserted in its groove. Higher the setting, colder will be
the cabinet temperature.
A)
The thermostat knob is set at position 1 at works. The
inside space temperature depends on the
surrounding temperature. Please check the inside
temperature whether its value is between +4 °C and
+8 °C.
If it is observed that the cabinet temperature remains
steady at a higher temperature than the required
range of +4° to +8°C, turn the thermostat knob
clockwise to a higher setting (fig. 22). Observe for
several hours. Select a higher setting, if required, until
the required temperature is obtained and it remains
steady.
B)
If it is observed that the cabinet temperature has gone
lower than the required range, turn the thermostat
knob anti-clockwise to a lower setting (fig. 23).
Observe for several hours. Select a lower setting, if
required, until the required temperature range is
obtained and it remains steady.

Water in the tubes will be frozen, within 1-3 days,
