ICE MAKER CLEANING PROCEDURE
Prep-Clean:
Using full strength ice machine cleaner on a section
of coarse surface material (terry cloth) wipe down the
inside walls of the food zone, wipe out the water pan,
wipe off the water curtain and evaporator plastic extru-
sions. Should the water distribution tube be heavily
scaled, remove and soak in full strength ice machine
cleaner while prep-cleaning.
Clean the water system and evaporator:
1. Place toggle switch to pump position to circu-
late cleaner through water system and across evapora-
tor.
2). Pour 4 ounces of approved cleaner into water
pan. (4 ounces (113.39g) is proper amount for all Servend
ice machines).
3). Float will bring in additional water during circu-
lation to produce proper cleaning ratio of 4 ounce cleaner
to 1/2 gallon (1.89Liters) of water.
4. Place toggle switch in pump position. Allow
cleaning solution to circulate for 10 to 15 minutes maxi-
mum.
5. Turn toggle switch to OFF position - this will al-
low cleaning solution to siphon out of machine. On later
production models (with manual dump switch), do not
turn toggle switch off.
Depress the manual dump switch and hold until
cleaner is dumped from system.
6. Fresh water will refill water pan - allow this fresh
water to recirculate for approximately 5 minutes to rinse
water system. Repeat step #5 twice (2 times).
7. After second rinse cycle, place toggle switch in
ice position. Allow product to produce one (1) slab of ice
- discard ice.
8. Cleaning cycle is now complete - return ice ma-
chine to normal operation.
WARNING: When using cleaing fluids or any chemicals, rubber gloves and eye protection should be worn.
Approved Ice Machine Cleaners:
Lime-A-Way or Calgon Nickel Safe (green color only)
Caution: Before attempting any cleaning of the ice machine, the ice in the bin or dispenser must be removed.
NOTE: A) Ice machine should only be cleaned when
required. Do not clean by a timed schedule of every
60 days, or etc.
B) Required cleaning of more than twice (2)
per year may require water treatment. Contact your
local Servend distributor.
Sanitize Cycle:
1. Check water level to be at mark on water pan - if
required, adjust float to maintain proper level.
2. Add 1/4 ounce (7.08g) unscented laundry bleach
(5.25% CI NaO concentration) to water contained in the
water pan in order to yield 200 PPM available chlorine.
Allow the pump to circulate this solution for 5 minutes
(or use a commercial ice machine sanitizer following the
directions on the container).
3. Depress the manual dump switch to drain the
water pan.
4. To sanitize the bin surface and other contact ar-
eas - use 1 ounce of liquid bleach per gallon of water
and wipe all surface areas with the solution.
5. Place toggle switch in ice position. Discard the
first batch of ice produced.
6. Should you ever have any questions on teh
proper procedure, please call you local distributor.
