Cleaning & Sanitizing Procedure
Hubbard Ice Systems –0800 616559
Revision - 19/2/2011
Note - This document is to give the preferred instruction as to how cleaning and sanitising of the modular ice
machine is completed. This does not replace the instruction given within the full service manual, but to assist
and supplement it. Cleaning should only be undertaken by competent or trained personnel.
Note - Good hygiene working practice should be undertaken before and during any cleaning regime.
Cleaning Schedule
WARNING; Before carrying out any cleaning operation, please ensure that the ice maker is
disconnected from the electrical supply.
NOTE –If external stainless steel panels are not cleaned regularly, stains or water marks could begin
to show. It is important to prevent these stains forming on these stainless steel surfaces otherwise
there is a risk of a chemical reaction which could penetrate the chromium oxide film, this could
result in a ‘rust’ and ‘pitting’ of the panels.
Do not use abrasive products, such as steel wool pads, acids etc. Since these could damage the
various surfaces. In case of persistent stains, normal abrasive detergents or products specific for
stainless steel are readily available on the market.
Suggested Weekly Cleaning.
Pull out the removable condenser intake air filter on the side of the machine, vacuum to clean or
wash in clean water and dry, refit it in to the runner moulding once complete.
Wipe all external stainless steel panels & front panel assembly with a soft cloth and suitable
sanitising solution (Or pre-impregnated sanitizing wipes specific to the task).
Empty/Scoop out all the ice cubes stored into the storage bin below the machine in order to prevent
them from being contaminated with the cleaning solution used.
Wipe clean and rinse the inner surfaces of the storage bin using an appropriate sanitising product
along with the cleaning of the inside of the unit storage bin door.
Cleaning/Sanitising Procedure.
CLEANING/SANITISING INSTRUCTIONS OF WATER SYSTEM
Clean/Sanitise the water system, evaporator, bin and spray jets using a solution of a suitable
Ice Machine Cleaner/Sanitiser.
NOTE. Cleaning requirements vary according to the local water conditions and individual
user operation. Continuous check of the clarity of ice cubes and visual inspection of the water
spraying parts before and after cleaning will indicate frequency and procedure to be followed in
local areas.
Prior to the cleaning of the water system, it would be required to first clean the ice thickness sensor
and the water trough above the evaporator.
1. Wait until the end of the defrost/harvest cycle then push the RESET BUTTON for 6-8
seconds.
The machine should stop with the blinking of the Yellow LED (slow blink).
2. Remove the front unit panel & evaporator cover so to gain access to both the water sump
area and the evaporator section.
3. Remove the ‘ice thickness sensor’ from its bracket and clean by immersing the sensor into a
‘jug’ of descaling solution then with a cloth pre-soaked in a descaling solution (ensure both
the metal contacts & plastic bracket is cleaned to remove any mineral build up.
4. Disconnect the water hose from the tubing of the trough and remove the ‘water trough’
from its location by squeezing the retaining brackets, slide to the right and lift above the
evaporator so to then clean & rinse clear of any slime or scale build up.
5. Pour into the water sump, ‘Ice machine cleaner’ directly into the reservoir.
- MV 306-426 150 cc
- MV 456-606 250 cc
- MV 806-1006 350 cc
6. Push again the RESET BUTTON. The water circulating pump should start to operate with a
fast blinking of the Yellow LED while the water inlet valve will be energized to then the fill up
the water sump.
7. After approx 15 minutes (or longer if the scale build up is considered heavy), push again the
RESET BUTTON. The P.C. Board will now put the machine into an automatic rinsing mode
with the special blinking (blink twice and repeat) of the Yellow ‘Bin Full’ LED.
NOTE. The amount of Cleaner and the time needed for the cleaning of water system depends on the
water conditions locally.
NOTE: The RINSING mode consists of:
a) Energizing the water drain valve and the water pump for 40 seconds to empty the reservoir
b) De-energizing the water drain valve and the water pump for 1 minute
c) Energizing the water inlet valve until the water level fills up the water sump
d) Energizing the water pump for 1.5 minutes.
The above ‘rinsing’ sequence is automatically repeated 7 times so to be sure any possible trace of Ice
Machine Cleaner is removed.
8. At the end of the 7th Rinsing cycle, the P.C.Board stops the operation of the machine with
the blinking (slow) of the Yellow ‘Bin full’ LED
9. Pushing the RESET BUTTON for 6-8 seconds then sets the machine to restart in a new
freezing cycle.
10. Replace the sump covers, evaporator deflector cover and front unit panel.
11. Discard the next 2 batches of cubes made to ensure all the ice machine cleaner is removed
(no sour taste).
WARNING. The Ice Machine Cleaner/Sanitiser contain harmful fluids.
Please refer to any supplied MSDS document issued for handling of fluids.
KEEP OUT OF THE REACH OF CHILDREN.
If the water system is to then be sanitised, it is to be completed as per the preferred instruction
further down this document
Sanitising
NOTE. Sanitising of the water system is recommended to be done once every 3 months or more
frequent, depending on use.
1. Prepare in a plastic container the preferred sanitation solution as per manufacturer dilution
using cold water –approx a 10% ratio is suggested.
NOTE. Never mix the descaling solution with the sanitising solution.
2. Load into the empty ‘water sump’ then following the procedures as per cleaning/descaling
procedure (from point 6 ) just shortening then the operation of the unit ‘clean mode’ to 10
minutes for system sanitising.
3. Push the reset button x 1, to place unit into automatic ‘rinse’ mode (7 cycles).
4. At the completion of the sanitising cycle make sure of proper texture and clearness of the ice
cubes and that, they do not have any taste –test with the ‘testing’ strips to ensure removal
of all solution.
5. Allow the unit to make 2 batches of ice to then discard…………
ATTENTION. In case the ice cubes are cloudy-white and have an acidic taste, melt them
immediately by pouring on them some warm water. This to prevent that somebody could use
them.
6. Wipe to sanitise the inner surfaces of the pre-emptied storage bin before resuming normal ice
making operation.
Hubbard Ice Systems offers suitable product for the use for cleaning & sanitizing of all ice
dispensers, please call 0800 616559 for further detail and the appropriate MSDS data
sheets.
