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  
Ensureallcomponents, fastenersandthumbscrewsaresecurelyinplace  
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 sys-  
tem is opened.  
3. Do not leave the system open for longer than 15 minutes when replac-  
ing 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 refrig-  
erant 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  
Download from Www.Somanuals.com. All Manuals Search And Download.  
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 de-  
pends 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 recom-  
mends 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 decom-  
posed 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 refrig-  
erant, raising the pressure with nitrogen and using an electronic leak  
detector.

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.  
1) Turn off the power supply, and remove the panels.  
2) Remove the Terminal Cover on the Compressor, and disconnect the Compressor  
Wiring.  
3)Recovertherefrigerantandstoreitinanapprovedcontainer, ifrequiredbyanapplicable  
law.  
4) Remove the Discharge, Suction and Access Pipes from the Compressor using brazing  
equipment.  
WARNING  
When repairing a refrigerant system, be careful not to let the burner flame  
contact any electrical wires or insulation.  
5) Remove the Bolts and Rubber Grommets.  
6) Slide and remove the Compressor. Unpack the new Compressor package. Install the  
new Compressor.  
7) Attach the Rubber Grommets of the prior Compressor.  
8) Sandpaper the Discharge, Suction and Access Pipes.  
9) Place the Compressor in position, and secure it using the Bolts.  
10) Remove plugs from the Discharge, Suction and Access Pipes.  
11)BrazetheAccess,SuctionandDischargelines(Donotchangethisorder),whilepurging  
with nitrogen gas flowing at the pressure of 3-4 PSIG.
