Water Supply Requirements; Electricity Supply Requirements - Valmar SNOWY TTi Manual

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 TEMPERATURE
WATER PRESSURE
WATER FLOW
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.

4.3 ELECTRICITY SUPPLY REQUIREMENTS

Prior to connecting the appliance to the power source, the voltage and the
maximum power current allowed in the network must be checked and the
appliance must be protected externally with FUSES and the MAIN SWITCH.
Permitted voltage of three-phase appliances (400/50/3):
nominal voltage
400V
Permitted voltage of three-phase appliances (230/50/3):
nominal voltage
230V
Permitted voltage of one-phase appliances (230/50/1):
nominal voltage
230V
Permitted voltage of one-phase appliances (208-220/60/3):
nominal voltage
208-220V
Permitted voltage of one-phase appliances (208-220/60/1):
nominal voltage
208-220V
The diameter of each phase conductor must be of an appropriate dimension
(corresponding to the power of the fuses). It is also necessary checked the
frequency.
The MAIN SWITCH must be installed in the immediate vicinity of the appliance,
where it must be easily visible, accessible to the operator and appropriately
marked.
