Clean/descale ice machine
1.
If ice machine was running recently, ensure that the evaporator is completely free of ice before proceeding.
2.
Disconnect power to ice machine.
3.
Remove any ice machine panels required to gain access to water reservoir and electrical control box.
4.
Turn compressor switch on electrical box of ice machine to OFF position.
5.
Remove water reservoir cover and close water supply valve (or block up reservoir fl oat).
6.
Drain water from reservoir by releasing evaporator drain tube from fl oat reservoir bracket, removing plug
from drain tube and releasing (unclamping) pinch clamp (if equipped).
7.
Plug drain hose, replace drain line in reservoir bracket and pour part of
Solution A
into reservoir, fi lling it
almost to overfl owing.
8.
Remove stainless steel ice compression nozzle and drain lines and submerge in a cup of
Solution A
while
cleaning/descaling rest of system. (Flake ice machines have no ice compression nozzle and drain lines.)
CAUTION:
To avoid potential pitting, do not soak parts in
Solution A
for more than 45 minutes.
9.
Restore power to ice machine (gearmotor will run; compressor and fan will not).
10.
Inspect evaporator drain pan and drain line and remove any accumulated scale build up.
11.
After 15 minutes, turn power OFF; drain solution from reservoir and evaporator.
12.
Fill reservoir almost to overfl owing with clean water to rinse. Drain. Repeat two more times.
13.
Rinse ice compression nozzle and drain lines in clean water.
Sanitize ice machine
14.
Submerge ice compression nozzle and drain lines in a cup of
Solution B
while following steps 15-21.
15.
Connect ice transport tube directly onto evaporator outlet port without ice compression nozzle.
16.
Fill reservoir almost to overfl owing with
Solution B
.
17.
Restore power to ice machine (gearmotor will run; compressor and fan will not).
18.
After 10 minutes, turn compressor switch to ON position.
19.
As unit starts to make ice, continue to pour
Solution B
into reservoir, maintaining level just below reservoir
overfl ow.
20.
Continue to make ice with
Solution B
for 20 minutes.
21.
Turn power to ice machine OFF.
22.
Disconnect ice transport tube from evaporator outlet port. Rinse ice compression nozzle and drain lines in
clean water and reinstall on evaporator outlet. Reconnect ice transport tube to ice compression nozzle.
23.
Drain any remaining
Solution B
from evaporator.
24.
Fill reservoir almost to overfl owing with 120 F (49 C) clean water to rinse. Drain. Repeat two more times. Re-
clamp pinch clamp, replace drain plug, and re-secure drain tube
ensuring that end of drain tube is above
water level in reservoir
.
25.
Open water supply valve (or unblock fl oat) and replace reservoir cover; restore power to ice machine
and ensure compressor switch is in ON position. Make ice for at least 15 minutes to fl ush any remaining
Solution B
from system (RIDE ice machines with long ice transport hoses may take longer to fl ush out).
Discard this ice and all ice made during sanitizing.
26.
Reinstall all parts and replace any panels removed prior to cleaning.
