If great power heaters are used then the safety thermostat must be absolutely applied on the
evaporator. This thermostat must operate on the different principle, for instance: mechanical
thermostat.
V. THE PRINCIPLE FOR INSTALLATION OF SENSORS, TYPES OF
PROTECTIVE CASES
1. For each type of the manufactured equipment a place for securing the sensors and the SCCB settings
should be determined experimentally. Absolutely do not change the fastening location nor the way the
sensors are secured nor modify SCCB settings without prior carrying out new tests relating to temperature
stabilization and equipment defrosting cycle !!!
2. Fastening of the chamber sensor must be done in such a way so that it does not get in contact with food
products and is not exposed to damage when cleaning the equipment. The sensor can be fixed using a
special plastic bracket. This solution causes fast (on/off time delays see VI p. and Błąd! Nie można odnaleźć

temperature in the unit. When desired or necessary to slow down and "smooth" the time of sensor
response to the temperature changes we recommend to fix it to the metal part of the unit.
3. Fasten the evaporator sensor in the way to ensure maximum and good contact with the evaporator lamella
and in place where ice remains for the longest time during defrosting. Its fastening should prevent it from
being pushed out by the growing ice. The sensors, wherever possible, should be fixed vertically so that the
cable exits from the bottom of the sensor.
4. Sensor cables can be shortened or extended in any way, however with respect to the following rules:
- do not cut the sensor cable at a section smaller than 0.5 m. From the case
- it is not recommended to extend the sensor cable to more than 20 m.
- THE SENSOR CABLES CAN BE CONNECTED TO THE TERMINALS OF THE ACTUATOR SENSORS IN ANY
WAY!!!
(in the same way as you connect the plug to the ~230V outlet)
- for cable extension we recommend using OMY 2x0.5 mm type conductor
- connect the extended cables with great care, by soldering each pair of cores and put thermally
shrinkable jackets on them. Then apply water-proof silicone on the joint and clamp one more thermally
shrinkable jacket on it.
- whiten the ends of the conductors connected to SCCB with tin.
