Caution for your Safety
Maintenance:
Cleaning: Clean the surface of the controller with a soft
moist cloth. Do not use abrasive detergents, petrol, alcohol or solvents.
WIRING:
The probe and its corresponding wires should
never be
installed in a conduit next to control or power
supply lines. The electrical
wiring should be done as shown in the diagram. The power supply
circuit should be connected to a protection switch. The terminals admit
wires of upto 2.5sq mm.
WARNING:
Improper wiring may cause irreparable damage and
personal injury. Kindly ensure that wiring is done by qualified personnel
only.
