4 REQUIREMENTS AND CONDITIONS FOR NORMAL
OPERATION OF THE APPLIANCE
Before connecting the appliance to electricity supply, the operator must make sure
that environment requirements have been met: the temperature and humidity of
the air must be appropriate and the water supply and electricity networks comply
with all requirements for normal operation of the appliance.
When the characteristics of either the water supply or electricity network fail to
meet the requirements for normal operation, the machine must not be connected
to power supply.
4.1 ENVIRONMENTAL CONDITIONS
Prior to connecting the appliance, the temperature and the humidity of the
environment, in which the appliance will be operated, must be assessed and
checked.
If room temperature drops under 0 ºC (273K), water must be released from the
condenser.
4.2 WATER SUPPLY REQUIREMENTS
Prior to connecting the appliance to the power source, the temperature, pressure
and water flow from the water supply network must be checked.
Permitted water temperature and water pressure from the water supply network:
Water supply must be checked for all conditions that are required for alimentary
use.
Low water pressure causes the cooling system to function improperly. The cooling
gas does not condense, thus causing the compressor to overload. In such cases,
the safety pressure valve kicks in and switches off the compressor.
The results of mixture treating and ice cream production when the water pressure
is too low are not as good as when the water pressure is normal.
The maximum presence of chlorides in water is 120 ppm. Exchangers are not
suitable for the use of salt water.
