7. WATER SUPPLY AND DRAIN CONNECTIONS

(For the U.K. only, the connections must be in accordance with current
requirements of the Model Water Byelaws 1986 SI No. 1147)
* Only potable water should be used for the icemaker.
* Water supply pressure should be minimum 0.5 bar and maximum 8
bar. If the pressure exceeds 8 bar, use a proper pressure reducing
valve. Do NOT throttle back the supply tap.
* A plumbing permit and services of a licensed plumber may be required
in some areas.
* The icemaker drain is gravity flow, so ensure drain pipe has an
adequate pitch or fall.
* Water should drain into an open trap.
* The Storage Bin has two drain outlets. The upper/outer one is for
dump from the icemaker, and the lower/inner is for the Bin. The two
drain lines must be separated to prevent a backflow into the Storage
Bin.
1) Attach the angled end of white flexible inlet hose (accessory) to the
G3/4 fitting on the left side of the icemaker as indicated, ensuring
rubber sealing washer is correctly positioned. Hand tighten
sufficiently to provide leak free joint (Fig. 23).
2) Attach the other end of inlet hose to the water tap (Fig. 24), noting
washer is correctly positioned before hand tightening as above. It
is a wise precaution to have a stop valve within easy reach.
3) Hand tighten grey flexible outlet hose (accessory) onto the R3/4
fitting on the left side of the Storage Bin as indicated, ensuring
rubber washer is correctly positioned to obtain a leak free joint. The
pipe can be cut to length as necessary to suit position of main drain.
Note: Jointing compounds should be approved and suitable for
potable water use.

8. START-UP PROCEDURE

Before starting the unit, energise the Oil Heater around the lower part
of the Compressor to prevent a starting failure caused by the refrigerant
staying inside the Compressor:
1) Move the Washing Switch on the Control Box to the "WASH" position.

2) Push the Bin Control Switch to the right into the
"bin full" position, and fix it there with tapes.
3) Connect the power supply.
4) After 10 seconds in the defrost cycle, the unit
stops. Leave the unit for 12 hours (Oil Heater
energised).
5) Open the water tap.
6) Move the Washing Switch to
t h e " I C E " p o s i t i o n , a n d
r e l e a s e t h e B i n C o n t r o l
Switch into the initial "running"
position.
7) The following should occur in sequence:
a) Compressor will start (Hot Gas Valve open).
b) Water Pan will fully open.
c) Water Solenoid will open.
d) Water Pan will start to close (Hot Gas Valve closed).
e) Water Pan fully closed - Pump Motor will start.
f) Water Solenoid will close.
8) The unit will start a freeze cycle in 80 seconds.
1. Check the conditions and quality of the ice production.
2. Do not use ice produced in the trial run. It might be contaminated
with foreign matter in the water circuit. Discard or flush
down the drain.

9. FINAL CHECKS

1) Is installation free of water leaks?
2) Is the icemaker free from vibration?
3) Are all the panels fixed and secure?
4) Has the user been instructed on correct machine use and handed
the Instruction Manual?
