WATER CONNECTION: A 3/8" NPT x 1/4" flare elbow fitting is supplied with this brewerforthe   water line connection. Use 1/4" copper tubing and flare nut to hook up your water source behind   the machine. It is important to use a good water filter in the system before water enters the   Alphabrewer.   CAUTION: Do not connect this brewer to hot water line. Inlet valve is not rated   for hot water! Do not connect to water softener system.   2. Remove the top cover and lid from the heating tank. By hand, fill heating tank with water until   heatingelementissubmerged.   3. Locate the thermostat (see figure 1). Twist the thermostat stem clockwise as far as it will go.   4. Replace the heating tank lid and top cover.   5. Plug the power cord into a 115 VAC electrical outlet.   6. Turn on power at the ON/OFF power switch (front panel). At this time, if the heating tank was not   completelyfilled, theautomaticliquidlevelcontrolwillrefillthetank.   7. Allow about fifteen minutes for the water in the heating tank to come up to proper temperature.   The READY TO BREW light will turn on when the initial warm-up has completed. The unit is now   ready to brew. Because water expands when heated, there may be a slight overflow discharge   at this time.   8. Althoughthisbrewerhasbeenthoroughlytestedandcleanedatthefactory, wesuggestthatyou   run several brewcycles of just hot water to flush the water lines of any air that may affect brew   volume.   COFFEE REQUIREMENTS   The Alpha coffee brewer will produce excellent results using most grades of   coffee available from your coffee distributor. Coffee suppliers can provide   coffeeinconvenientpre-measuredenvelopes.   The Alpha coffee brewer is designed for ground coffee; freeze dried or   liquid coffee products will not work.   TheWilburCurtisCompanymanufacturesbulkcoffeedispensers(Models   MCD-7 or MCD-7G) that consistently dispense ground coffee in selected   amounts.   Dispenser   [ 1 ]   COFFEE BREWING   1. Place a paper filter into the brew cone.   Pour ground coffee into the filter.   2. Slide the brew cone into place. When pushed in against the stop,   the brewcone fits into the slide rails and centers   it under the sprayhead.   3. Place a clean coffee decanter on the warmer plate.   4. To start brewing, push in the momentary brew switch,   located on the front panel. The brew cycle will take   approximately three minutes to complete.   5. The warmer plates keep the coffee at serving temperature To activate the warmers, push the desired warmer switch,   located on the front panel.   WARNING   TO HELP AVOID PERSONAL INJURY:   l l l FOLLOWALLBREWINGANDWARMINGINSTRUCTIONS.   HOTCOFFEE!ALLOWBREWCONETOFINISHDRIPPING.   USEONLYCURTISAPPROVEDACCESSORIES.   [ 2 ]   MAINTENANCE & CLEANING OF BREWER   Regular and preventive maintenance is essential in keeping your Alpha system looking and working   likenew.   CAUTION When cleaning your Alpha System, do not use cleansers, bleach liquids, powders or any   other substance that contains chlorine. These products promote corrosion and will pit the stainless   steel. USE OF THESE PRODUCTS WILL VOID WARRANTY.   PREVENTIVE MAINTENANCE   1. Remove the sprayhead from the brewer and clean it once a week or more often in heavy lime   areas.   2. Clean the faucet seat cup and replace it if cracked or leaking.   3. The inside of the heating tank should be de-limed at least every six months and more often in   areas with especially hard water.   CLEANING   Using a daily routine of cleaning the external parts of the Alpha brewing system should maintain its   new appearance and better tasting coffee.   1. Wipe off any spills, dust or debris from the exterior surfaces.   2. Clean the outside of the brewer with stainless steel polish. Coarser agents may scratch the   machine.   3. Slideoutbrewcone. Rinsethoroughlywithcleanwater.   4. Remove the sprayhead and clean. Clean around the dome area, wiping with a non-toxic cleaner.   5. Clean the brew cone rails with a damp cloth or brush.   6. Drythoroughlywithacleancloth.   [ 3 ]   TROUBLE SHOOTING   ANY SERVICE DONE ON THIS UNIT MUST BE PERFORMED BY A QUALIFIED SERVICE   TECHNICIAN.   PROBLEM: Water does not flow into heating tank...   POSSIBLE CAUSE   SOLUTION   Water line turned off or water filter   clogged.   Disconnect the water line and test for water flow.   Coil on Water Inlet Valve has burnt   out.   Turn machine off. Disconnect wires from water inlet coil   terminals and connect a power cord to the termi-   nals. Plug into a 115V outlet to verify that water flows   through when plugged in and stops when cord is   disconnected. If the valve does not respond to this test,   valve is defective. Replace valve or coil.   Grounded Water Level Probe.   When water in the heating tank is below the probe tip, the   tank should be refilling. Pull wire off the probe terminal. If   water starts flowing into the tank, probe may be grounded.   Clean or replace probe.   To reduce the recurrence of grounding, tightly wrap probe   with Teflon tape to 1/8" from tip.   Defective Liquid Level Control (LLC)   board.   Remove ORANGE wire from probe terminal. Do not allow   wire to touch any electrical parts. Test voltage at terminals   of Water Inlet Coil. This should read 110 to 220 Volts. If   there is no voltage, go to LLC Board. Check board for loose   connections or a bad ground. If this is okay, board is   defective. Replace LLC Board.   PROBLEM: Water is overflowing from the heating tank   POSSIBLE CAUSE   SOLUTION   Defective Water Inlet Valve.   Turn power off. Observe water level in tank. If water continues   to fill tank, the valve may need cleaning or you may have a   defective valve. Clean out or replace valve.   Pull wire off from probe terminal. Touch the metal side of   water tank with connector end of wire. If water stops flowing,   probe needs cleaning or replacement.   Lime deposits on Probe.   Liquid Level Control board must be securely grounded to it's   mounting bracket. Check for loose connections. Make sure   there is no voltage present at the inlet valve terminals. If   voltage is present, replace LLC board.   Loose or ungrounded Liquid Level   Control (LLC) board.   [ 4 ]   PROBLEM: water in tank does not get hot...   POSSIBLE CAUSE   SOLUTION   Thermostat turned off.   Check the thermostat to make sure stem is turned all the way to the   right.   Burned out Heating Element.   If thermostat is on (closed) you should read 110/120 volts at the   element terminals. Voltage present at these points but no heat,   indicates the element is burned out. Replace it.   PROBLEM: Water does not spray over coffee...   POSSIBLE CAUSE   SOLUTION   Remove the spray head from the brewer and inspect for   obstructions. Clean and reinstall.   Clogged Spray Head   Remove tank lid. Determine if there is water in the tank. Follow   instructions on page 3, Problem: Water does not flow into Heating   Tank.   No water in Heating Tank.   Check the brew switch for continuity between terminals 1 (white   wire) and 2 (blue wire). While pressing the switch. If there is no   continuity or if you have to push the switch three or four times to   read any continuity. Replace the brew switch.   Defective Brew Switch.   Defective Timer.   When the timer is activated by the Brew Switch you should read 110   to 120 volts across terminals 6 and A of the timer. The RED wire on   terminal 6 supplies power to open the Dump Valve. If you can't read   any voltage across the two terminals, replace the timer.   Check the dump valve coil using a volt meter on the dump valve   terminals. If it is showing 110 to 120 volts but valve does not actuate,   valve is defective; replace the valve.   Burned out Dump Valve.   [ 5 ]   ALPHA 3X   ILLUSTRATED PARTS   THIS FIGURE (AND FIG. 4.)
