Services:
•Cold water supply terminated with a ¾ BSP washing machine style stop
valve.
•Mains drainage with a connection point lower then the drain outlet of the
machine. Connection point must be at least 1 ¼" diameter open and trapped
(similar to a domestic washing machine) with any connection made to include
a suitable ‘back flow’ prevention device to ‘EN1717’. If drain is too high, a
stand or condensate pump must be used.
•13 amp socket outlet. (Due to potential high starting current, a socket adaptor
with other appliances should not be used.)
Note: If an external condensate pump is to be used, then 2 x 13 amp socket outlets
are required.
Check the following:
•Ambient temperature - minimum 10°C, maximum 40°C
•Adequate space at rear of machine for water and drain connections.
•Minimum airflow clearance requirement of 15cm to both sides of machine.
Note:
If clearance is less, ice production rate will decrease by as much as 25% due to
potential overheating.
•Fit 13 amp plug top (fitted with a 13A fuse) to equipment cable.
•Fit water inlet hose to machine. Do not overtighten.
•Fit flexible drain hose to drain fitting of machine and secure using clip
provided.
Note:
Both hose’s are fitted with one straight end and one angled end. Use which ever is
the most suitable for that installation.
•Connect water inlet hose to water supply. Do not overtighten.
•Connect drain hose to main waste drain provided by inserting hose into
upstand (similar to domestic washing machine).
Note:
To prevent drainage problems caused by loops in the hose, reduce hose length as
far as reasonably practicable.

conditions (electrically disconnected) the delay or stand-by period will be 10 minutes.
The machine will run an auto calibration of ice level control showing FØ2 code for few
seconds. Every restart from other operating conditions with the unit electrically connected it

control is interrupted for 10 seconds continuously.
E. After every 12 hours of unit operation, an automatic purge and refill of the water system to
help prevent the growth of bacteria when the machine is not seen to be working for many
hours (overnight and/or Bin full condition).
F. There is an automatic ‘agitation’ and dispensing of a small amount of ice if the unit
remains unused for any 12 hour period.
