fittings and a shut off valve installed in an accessible position between the water supply line and the unit.
WATER SUPPLY - WATER COOLED MODELS.
The water cooled versions require two separate inlet water supplies on models 40 and 60, one to supply water for the ice production and one
for the water cooled condenser.
Connect the male fitting of the condenser water inlet solenoid valve, using the second flexible tubing supplied, to the cold water supply line
with regular plumbing fittings and a shut off valve installed in an accessible position between the water supply line and the unit.
WATER DRAIN.
The recommended drain tube is a plastic or flexible tube with 18mm (3/4in) I.D. that runs to an open trapped and vented drain. When the drain
is along run, allow 3cm pitch per metre (1/4in per foot).
A vertical open vent, at the unit drain connection is also required for proper sump drainage.
WATER DRAIN – WATER COOLED MODELS.
The water drain line from the condenser, on water cooled versions, is internally connected with the drain fitting of the unit.
It is strongly recommended therefore to install a vertical open vent to the high point of the drain line high enough to ensure good drainage and
to direct the drain line to a trapped and vented floor drain receptacle.
This ensures proper flow of the drained water as, in the case of poor drainage, the water running out of the condenser may leak through the
unit drain tubing into the ice storage bin or into the sump reservoir.
NOTE. The water supply and the water drain must be installed to conform to the local codes. In some cases a licensed plumber and/or
a plumbing permit is required.
1.5 Final Checklist.
1. Is the machine in a room where the ambient temperatures are within a minimum of 10°C (50°F) even in winter months?
2. Is there at least a 15cm (6in) clearance around the unit for proper air circulation?
3. Is the machine level? (IMPORTANT)
4. Have all the electrical and plumbing connections been made, and is the water supply shut-off valve open?
5. Has the voltage been tested and checked against the rating on the data plate?
6. Has the water supply pressure been checked to ensure a water pressure of at least 1 bar (14psi)?
7. Check all refrigerant lines and conduit lines to guard against vibration and possible failure?
8. Has the bin liner and cabinet been wiped clean?
9. Has the owner/user been given the User Manual and been instructed on the importance of periodic maintenance checks?
10. Has the owner/user been given the name and telephone number of the authorised Service Agency in case of breakdown.

NOTE With the system in
CLEANING/RINSING mode the water pump is the only component in operation to circulate the cleaning solution in
the
entire water system.
7. Let the unit remain in the
CLEANING/RINSING mode for about 20 minutes then turn the program selector on STAND BY again.
8. Flush out the cleaning solution from the sump reservoir then pour onto the evaporator cavity two or three litres of clean potable water to
rinse
the mould cups and the platen.
If necessary remove the water spray platen to clean it separately as per step 3 of paragraph B.
9. Turn again the program selector on
CLEANING/RINSING. The water pump is again in operation to circulate the water in order to rinse
the
entire water system.
10. Flush out the rinsing water from the sump reservoir then turn the program selector on RESET/HI TEMPERATURE position and
immediately
afterwards to FREEZING OPERATION.
NOTE By setting the selector on RE-SET first and then to FREEZING OPERATION the ice maker will perform the 5 minutes WATER FILLING
phase i.e. the water inlet solenoid valve opens to allow the incoming water to rinse again the water system and to properly fill-up the sump
reservoir for the next freezing cycle.
11. Replace the evaporator cover and the unit service panels.
12. At completion of the freezing and harvest cycle make sure of proper texture and clearness of the ice cubes and that, they do not have
any
acid taste.
ATTENTION In case the Ice cubes are cloudy-white and have an acid taste, melt them Immediately by pouring on some warm water In order
to prevent somebody using them.
13. Wipe clean and rinse the inner surfaces of the storage bin.
REMEMBER To prevent the accumulation of undesirable bacteria it is necessary to sanitise the
interior of the storage bin with an anti-algae
disinfectant solution every week.
