3. SEQUENCE OF ELECTRICAL CIRCUIT
[a] When Power Switch is moved to “ON” position and Flush Switch to “ICE” position, water starts to be supplied to Reservoir.
28
[b] When Reservoir has been filled, Gear Motor starts immediately.
29
[c] Compressor starts about 60 sec. after Gear Motor starts.
30
[d] Bin Control operates, and about 6 sec. later, Compressor and Gear Motor stop
simultaneously.
31
[e] Low Water (Except Water-cooled Model).
32
[f] Low Water (Water-cooled Model), or Dirty Air Filter (Air-cooled Model), Pressure
Switch to “OPEN”, Compressor and Gear Motor operates intermittently.
33
[g] When Flush Switch is moved to “FLUSH” position, Flush Water Valve opens and
flushes Reservoir and Evaporator.
34
[h] When Flush Timer operates (for 15 min. every 12 hours).
35
[i] When 208-230V are supplied to Circuit Protect Relay, it protects the circuit from miswiring. If the power supply is properly connected, the contact of Circuit Protect Relay does not move even when the coil is energized.
36
[j] When input voltage is too low, (Less than 70%), Gear Motor Fuse (1.5A) is blown
causing the Compressor and Gear Motor to turn off immediately.

IV. ADJUSTMENT OF COMPONENTS
1. ADJUSTMENT OF WATER REGULATING VALVE - WATER-COOLED MODEL ONLY
The Water Regulating Valve also called “WATER REGULATOR” is factory-adjusted. No adjustment is required under normal use. Adjust the Water Regulator , if necessary, using the following procedures.
1) Attach a pressure gauge to the high-side line of the system. Or prepare a thermometer
to check the condenser drain temperature.
2) Rotate the Adjustment Screw by using a flat blade screwdriver, so that the pressure
gauge shows 260 PSIG (R-404A models/-F type), or the thermometer reads 100 -104°F, in 5 minutes after the icemaking process starts. When the pressure exceeds 260 PSIG, or the condenser drain temperature exceeds 104°F, rotate the Adjustment Screw counterclockwise.
3) Check that the pressure or the condenser drain temperature holds a stable setting.

VI. REMOVAL AND REPLACEMENT OF COMPONENTS
IMPORTANT
Ensure all components, fasteners and thumbscrews are securely in place after the equipment is serviced.
IMPORTANT
1. The Polyol Ester (POE) oils used in R-404A units can absorb moisture quickly. Therefore it is important to prevent moisture from entering the system when replacing or servicing parts.
2. Always install a new filter drier every time the sealed refrigeration sys­tem is opened.
3. Do not leave the system open for longer than 15 minutes when replac­ing or servicing parts.
1. SERVICE FOR REFRIGERANT LINES
[a] REFRIGERANT RECOVERY [EXCEPT F-1000MLF(-C)]
The icemaker unit is provided with two Refrigerant Access Valves - one on the low-side and one on the high-side line. Using proper refrigerant practices recover the refrigerant from the Access Valves and store it in an approved container. Do not discharge the refrig­erant into the atmosphere.
[b] REFRIGERANT RECOVERY [F-1000MLF ONLY]
The refrigerant charge on the F-1000MLF is provided from the external Compressor Rack Assembly. In the event that service is required on the F-1000MLF, close the Suction and Liquid Line Shut-off Valves located at the rear of the unit. Attach the Service Manifold Hoses to the High-side, Low-side and Evaporator Pressure Regulator (E.P.R.) access ports to purge or evacuate the unit. To recharge the system, simply open the Suction and Liquid Line Shut-off Valves after evacuating the F-1000MLF.
[c] EVACUATION AND RECHARGE [R-404A]
1) Attach Charging Hoses, a Service Manifold and a Vacuum Pump to the system. Be sure to connect Charging Hoses to both High-side and Low-side Access Valves.
IMPORTANT
The vacuum level and vacuum pump may be the same as those for current refrigerants. However, the rubber hose and gauge manifold to be used for evacuation and refrigerant charge should be exclusively for POE oils.
54
2) Turn on the Vacuum Pump. Never allow the oil in the Vacuum Pump to flow backward.
3) Allow the Vacuum Pump to pull down to a 29.9" Hg vacuum. Evacuating period de­pends on pump capacity.
4) Close the Low-side Valve and High-side Valve on the Service Manifold.
5) Disconnect the Vacuum Pump, and attach a Refrigerant Service Cylinder to the High-side line. Remember to loosen the connection, and purge the air from the Hose. See the Nameplate for the required refrigerant charge. Hoshizaki recom­mends only virgin refrigerant or reclaimed refrigerant which meets ARI Standard No. 700-88 be used.
6) A liquid charge is recommended for charging an R-404A system. Invert the Service Cylinder. Open the High-side, service manifold Valve.
7) Allow the system to charge with liquid until the pressures balance.
8) If necessary, add any remaining charge to the system through the Low-side. Use a throttling valve or liquid dispensing device to add the remaining liquid charge through the Low-side access port with the unit running.
9) Close the two Refrigerant Access Valves, and disconnect the Hoses and Service Manifold.
10) Cap the Access Valves to prevent a possible leak.
2. BRAZING DANGER
1. Refrigerant R-404A itself is not flammable at atmospheric pressure and temperatures up to 176° F.
2. Refrigerant R-404A itself is not explosive or poisonous. However, when exposed to high temperatures (open flames) R-404A can be decom­posed to form hydrofluoric acid and carbonyl fluoride both of which are hazardous.
3. Always recover the refrigerant and store it in an approved container. Do not discharge the refrigerant into the atmosphere.
4. Do not use silver alloy or copper alloy containing Arsenic.
5. Do not use R-404A as a mixture with pressurized air for leak testing. Refrigerant leaks can be detected by charging the unit with a little refrig­erant, raising the pressure with nitrogen and using an electronic leak detector.
55
3. REMOVAL AND REPLACEMENT OF COMPRESSOR IMPORTANT
Always install a new Drier every time the sealed refrigeration system is opened. Do not replace the Drier until after all other repairs or replacement have been made.
