Before servicing or opening the
•
machine, disconnect it from the local
mains supply by removing the earthed
socket.
• Please take precautions when cleaning
components with sharp edges.
• Do not use a pressure washer to clean
the flake ice machine.
Caution!
Risk of injury from chemical substances.
Take heed of the data sheet associated
with the disinfectant you are handling.
Wear personal protective equipment as
appropriate

Descale the water circuit
• Disconnect the flake ice machine from the
mains.
• Remove the mains plug.
• Take the ice from the ice tray to ensure it
does not come into contact with the desca-
ling solution.
• Connect the water supply.
• Lift the hood off the housing.
• Take the lid off the fresh water supply's float
housing.
• Connect a jumper between the two sensor
rods M3 on the lid of the float chamber. En-
sure that the sensor rods do not touch the
housing of the flake ice machine. This would
mean that current would be sent from the
condenser sensor to the PCB. As a result, the
machine would shut down due to an exces-
sive temperature.
• Disconnect the lower side of the connection
hose between the float housing and freezer
cylinder and collect the released water in a
tank.
• Remount the connection hose again.
• Mix the descaling solution by adding 0.2 to
0.3 ltr of SCOTSMAN scale remover to 2 to
3 ltr of warm water (45°C - 50°C).
• Pour the descaling solution slowly in to the
float chamber.
• Close the lid of the unit.
• Switch on the flake ice machine by plugging
it in.
• Once the flake ice machine is in operation,
gradually pour the descaling solution slowly
in to the float chamber.
• Wait until the entire descaling solution has
run through the system.
• Open the water supply. Allow the machine to
run until the ice that is produced is clean and
compact again. The ice that contains traces
of descaling solution will look yellow and be
soft.
