ATTENTION
Condenser fins are very sharp. Use extreme caution
when cleaning.
6. 1 MAINTENANCE (TO BE CARRIED OUT
BY QUALIFIED SERVICE PERSONNEL
ONLY)
1 - Monthly on NHT 1 GL model: remove the dust from the
condenser. To do this unplug the unit or switch off the 2-
pole wall breaker and then remove the panels.
2 - Annually: remove the panels and clean the inside of the
machine including the base, side panels, condenser, etc.
3 - Never remove the insulating jacket from around the
suction tubing of the evaporator (the copper tubing located
on the right side of gear motor). In case the insulating
jacket is missing replace the entire parts with original
spare parts from the supplier.
4 - In order to prevent any damages to the dispenser, all
plastics parts must be lubricated only with grease supplied
by the manufacturer or with another lubricating product
suitable for polycarbonate.
IMPORTANT
The electric diagram of the dispenser is located in the
inner part of the dispensing side panel.
7 DEFROST TIMER (OPTIONAL)
The Defrost Timer, located on the right side of the unit,
automatically switches the dispenser from Granita mode to
Soft Drink mode and the opposite. This means that during
defrost periods frozen Granita will melt to thermostat setting
temperature and once defrost period has expired, the product
Ugolini S.p.A.
automatically freezes down again to Granita setting viscosity.
To operate the defrost timer proceed as follows (see figure 20).
1 - Set the time of the day by rotating the dial clockwise (arrow
A). Never rotate the timer counterclockwise as this
would damage the internal mechanism. Align the current
time of day with the arrow B on the timer face. This is a 24
hour timer showing both A.M. and P.M.
2 - Program the defrost timer by pushing out on the tabs C
that correspond to the hours desired to defrost. Each tab
represents 15 minutes. A minimum of four to eight hours
are required to defrost frozen beverage (depending on
ambient conditions).
Note: when all the tabs are pushed in the defrost function is
OFF (the machine operates as if it were not equipped with
Defrost Timer).
