Monthly condenser cleaning (air-cooled icemaker only)
1. Use a vacuum cleaner or stiff brush to carefully clean condenser coils of air-cooled icemakers to ensure
optimal
performance.
2. When reinstalling counter panels in front of remote icemakers, be sure that ventilation louvers line up with
condenser air duct.
Semi-annual evaporator cleaning (every 6 months)
Solution A – Ice machine cleaner: Prepare one gallon (3.8L) of Follett
SafeCLEAN
™ Ice Machine Cleaner (one 7 oz packet) or equivalent. Solution
temperature must be at least 120° F (49°C).
Warning: Most ice machine cleaners contain citric or phosphoric acid that
can cause skin irritation. Read caution label on product and follow instructions
carefully.
Solution B – Sanitizing solution: Prepare 2 gallons (9L)
Combine 1 oz (30ml) bleach with 2 gal (8L) hot water (at least 120°F (49°C))
or use 200ppm of Ecolab Mikro-chlor Cleaner or equivalent 5.25% sodium
hypochlorite solution.
1. Remove icemaker panels required to gain access to water reservoir'
components (Fig. 5) and electrical control box.
2. Turn compressor switch on electrical box to OFF position.
3. Dispense all ice from dispenser.
4. Shut off water to icemaker.
5. Drain water from reservoir through float/evaporator drain line (Fig. 5.1).
Reinsert hose into hose clip (Fig. 5.3).
6. Fill reservoir and evaporator (Fig. 5.2) with Solution A.
7. Verify compressor switch is in the off position. Restart icemaker and
allow gearmotor to run for 15 minutes.
8. While waiting 15 minutes, follow steps 8a through 8c.
a) Remove ice compression nozzle (Fig. 6.1). Soak in Solution A.
Note: No compression nozzle on MFD400 series flake icemaker.
b) Descale drain pans (Fig. 6.2) by grasping firmly and gently bending
up and down. Vacuum residue out.
c) Inspect all drain lines. Clean as necessary with Solution A (Fig. 5).
9. Disconnect icemaker power.
10. Drain Solution A through float/evaporator drain line (Fig. 5.3). Rinse
evaporator by filling reservoir (Fig. 5.2) with potable water and draining
evaporator through float/evaporator drain line (Fig. 5.3) three times.
Reinsert hose into hose clip (Fig. 5.3) and insert plug into end of drain
line (Fig. 5.1).
11. Connect ice transport tubes (Fig. 6.3) directly to evaporator outlet ports
(without ice compression nozzle) (Fig 6.4).
12. Fill reservoir and evaporator (Fig. 5.2) with Solution B.
13. Rinse ice compression nozzle in clear water and submerge in cup of Solution B while performing steps 14
through 16.
14. Turn on bin signal switch in electrical box to allow gearmotor to run.
15. Wait 10 minutes. Turn compressor switch on.
16. Keep reservoir (Fig. 5.2) full of Solution B while making ice for 20 minutes.
17. Turn compressor switch off.
18. Rinse ice compression nozzles (Fig. 6.1) with water and reinstall.
Note: No compression nozzles on MFD400 series flake icemaker.
19. Drain any remaining sanitizing solution from reservoir through float/evaporator drain line (Fig. 5.1).
20. Fill reservoir (Fig. 5.2) with 120˚F (49˚C) water. Empty water through float/evaporator drain line (Fig 5.3).
Repeat 3 times.
21. Turn on water to icemaker.
22. Turn compressor switch on.
23. Replace reservoir cover and any panels removed to clean icemaker.
24. Make ice for 30 minutes. Dispense and discard all ice.
25. Clean and sanitize dispenser as outlined in dispenser operation and service manual.
