Equipped with Option 46 Automatic Refill
Option 39 Low Water Cut-Off System
General Description
This unit is a high temperature hot water boiler. It consists of a non-pressure, vented water compartment into which is installed an electric immersion heater thermostatically controlled through a contactor relay, to keep the water always at the desired brewing temperature. Automatic refill maintains water level in water compartment. All control system components are enclosed in a stainless steel housing on the right end of the urn:
A master ON-OFF switch shuts off entire unit, including heater circuit: Separate low water cutoff system protects heater and entire unit from damage.

IMPORTANT TO ALLOW 6" CLEAR SPACE TO RIGHT ON CONTROL BOX FOR ACCESS. Urn should be level, both front to back and left to right.
CONNECT WATER LINE. 3/8" NPT water inlet located at right end. Provide shutoff valve and union in supply line near urn. Cold or hot water may be used, but hot water will give greater gal­lon per hour capacity. We strongly recommend the use of copper or aluminum tubing to provide flexibility and avoid strain on the unit. 3/8" O.D. Tubing is recommended.
CONNECT URN TO ELECTRIC POWER. Check to be sure that name plate marking of voltage phase and number of wires matches supply lines. Remove cover on control housing. Terminal block for line connections located in housing on right end. See drawing, as required. It is rec­ommended that a fused disconnect switch be installed near urn. Urn body must be grounded either through metallic conduit or else by means of ground wire. An experienced electrician should be responsible for the installation of the unit, and its associated supply line. NOTE: Neutral wire required on all single phase and on 208 volt 3 phase power supplies to operate 120volt AC control circuit. Do not replace cover until completion of installation.
FILL WATER COMPARTMENT. Turn on water supply and electric service to urn. Turn master switch on. Do NOT turn on thermostat until water shows in gauge glass (approximately 6 min­utes). When water shows, remove adhesive WARNING label from thermostat knob. Turn thermostat knob maximum clockwise to BREW position. Pilot light over knob should light showing heater power on. Water compartment will fill automatically to stop-full level, and should reach operating temperature approximately 45 minutes later. When the pointer on thermometer approaches the "W" in the blue BREW zone, unit is ready for operation.
REFILL RATE ADJUSTMENT. To gain maximum capacity of the boiler, and shorten heat recovery time, adjust the water inlet flow regulator (located inside the control box) according to the chart provided. Turning the threaded adjustment shaft clockwise increases the flow rate, counterclockwise will decrease it.
American Metal Ware Hot Water Boiler Page 2
TO CHECK REFILL RATE, allow water to fill to stop/full level automatically; then turn off master switch. Draw off 1 gallon of water from faucet. Turn master switch back on and time how long it takes for the water level to come up to stop/full mark again. Compare time with chart provided and adjust accordingly.

Dual Level Control: What it does:
Description and Operation of Dual Level Control System:
A.
B.
C.
A.
AUTO REFILL of the water compartment to keep the tank filled with water.
When water is used, the fill valve opens automatically to let in more. The fill valve closes when the water level reaches full.
LOW WATER CUTOFF to prevent burn out of the electric immersion heater when
there is not enough water to cover it. When low water occurs, the heat automatically switches off. The heat stays off until more water is added.
A device called a DUAL LEVEL CONTROL keeps the tank filled with water and
turns off the heat when water is low by simultaneously monitoring two different water levels.
Components
1. DUAL LEVEL CONTROL -
2. ELECTRODE ASSEMBLY -
3. METAL ENCLOSURE ­(TANK BODY)
switches power to both the thermostat and water inlet solenoid valve by sensing changes in water level.

Read installation instructions- thoroughly. Failure to comply can result in valve failure or system damage or personal injury. Do not use solenoid valves on applications or fluid media not specifically cataloged without prior approval of Alco Engineering Department. WARNING: DO NOT USE WITH FLAMMABLE OR EXPLOSIVE FLUIDS OR GASES. DO NOT USE IN EXPLOSIVE ATMOSPHERES. Use on these elements can result in product damage or personal injury. Use of solenoid valves on applications not specifically cataloged can result in valve failure and/or system damage or personal injury. Do not utilize a solenoid valve on any system where the system pressure can exceed the safe working pressure of the valve. CAUTION: Do not utilize a solenoid valve as a safety shut off. Do not exceed MOPD (Maximum Operating Pressure Differential) or valve may fail to open when energized.

CAUTION: Always disconnect power source and depressurize the system before working on solenoid valve or system. If the power disconnect is out-of-sight, lock it in the open position and tag to prevent unexpected applications of power. Direction of flow must correspond to flow Direction Schematics. Before energizing valve, be sure source voltage and frequency matches that on coil. Do not energize coil unless coil is securely attached to valve. See Coil Installation Instructions. Prolonged use in excessive ambient temperature or humidity may damage coils. Do not dent or bend or use enclosing tube as lever. A damaged enclosing tube may result in coil burnout or inoperative valve. Foreign matter in the valve may result in seat leakage, sticking open or closed, or coil burnout. To prolong valve life and ensure system cleanliness use a strainer.
Safety Instructions
ATTENTION: Read carefully before attempting to install, operate or service your Alco solenoid valve. Retain for future reference.
For ease of installation, an Alco solenoid valve can be installed in any position...gravity does not affect its operation.
NOTE:
Although all valves can be operated in any position, by mounting the valve upright there is less chance of malfunction caused by the collection of foreign material.
The solenoid coil can be rotated 360
O
for ease of wiring. If possible do not reduce thelength of the solenoid coil wire leads, so that if it becomes necessary to remove coil at a later date (for valve cleanout, etc), wire leads will not have to be disconnected. To allow for removal of the solenoid coil without removing the valve from its piping, allow at least 2 inches of clearance above the solenoid. Be sure valve is installed so that its flow arrow on valve body corre­sponds to direction of flow through piping.
1.
2.
3.
4.
Before removing coil from valve, disconnect electrical power source. Failure to do so will cause coil to burn out. Verify coil type, voltage and frequency. This information appears on the coil nameplate. Place coil over the enclosing tube. Coil may be rotated 360
O
for easy wiring. It is recommended that coil lead connections be soldered on D.C. and 24V - 50/60 Hz. applications. Install valve nameplate. Pull tab on valve nameplate and peel off paper backing to expose adhesive. Stick nameplate on top of coil housing and press nameplate down firmly. If installing replacement coil, use valve nameplate supplied with valve. Press nameplate down firmly. Install voltage nameplate and coil retainer. Press coil retainer down firmly to secure coil.
Be sure your wiring conforms to all local and national electric codes. For dual voltage coils, refer to the wiring schematic label on side of coil. The coil circuit of each solenoid valve should be protected by adequate fuses.

1. Junction box (AMG) is supplied as standard on all valves.
2. The following coil housings are available: a. Conduit Connection (AMC) c. Open Frame (AMF) b. GROMMET 113" Leads (AML) d. Spade Connection (AMS)
3. Use only Alco coils on Alco valves.
All moving parts and elastomers should be clean in appearance without permanent set springs should be free of corrosion. If any appear damaged, replace them with a parts kit which contains all moving parts necessary to rebuild valve to an "as new" condition. Inspect enclosing tube assembly for wear, exterior dents or other conditions which would impair free movement of the poppet and/or plunger assembly. Its interior should be clean and free from any obstructions. Be especially critical of its valve seat.
Apply correct voltage to valve solenoid and cycle solenoid sever­al times. A distinct click should be heard each time the solenoid is energized. Pressurize valve and check for leaks.
Note: Alco solenoid valves are equipped with a contlnuous-duty solenoid coil,which when energized for an extended period of time becomes hot to the touch...this is a safe operating temperature. Any excessive heating will be indicated by smoke and odor of burning coil Insulation.
Are all system relays operating? Is system source pressure as specified? Are all system components free from obstructions?
Check system fuses, electrical wiring and system source voltage as specified. Is flow direction arrow on valve the same as system flow direction?
Assemble in the reverse general order of disassembly. Lubricate gasket and "O" ring sparingly with a compatible lubricant such as a Silicon base lubricant. All moving parts, must move freely over the full length of its intended travel.
De-pressurize valve and disconnect electrical power source. To remove solenoid coil: Insert small screwdriver into gap in voltage nameplate. Slide screwdriver tip under coil retainer and snap off. If replacing coil, use knife to separate adhesive-backed valve nameplate from coil. Keep valve nameplate. To remove collar, use service tool X11981-1 shown in Figure 1.
