PLUMBER’S INSTALLATION LNSTRUCTIONS

CAUTION: Power to brewer must be O FF before proceeding with plumbin g installation

1) Attach flow/strainer assembly to back of brewer. Strainer inlet will point down.

2) Flush water line before installing brewer. Brewer should be connected to COLD WATER LLNE for best oper ation

3) Water pressure should be at least 20 lbs For less than a 25 ft run ,use 1/4’ copper tubing and connect to 1/2 or larger

Water line, For longer runs ,use 3/8” copper tubing & connect to 1/2” or larger water line and provide an adapter fitting for

Connection to the brewer.

4) lf installed with saddle valve, the valve should have a minimum of 1/8” port hole for up to 25 ft run, and 5/16” port hole for

over 25 ft runs.

5) Connect incoming water line to the strainer in the back of the brewer. Manufacturer recommends connecting to copper tubing.

INSTALLATION INSTRUCTIONS

WARNING: read and follow installation instructions before plugging or wiring in machine to electrical circuit. Warranty will be

Void if machine is connected to any voltage other than that specified on the name plate.

FILL BREWER TANK WITH WATER BEFORE CONNETING TO POWER SUPPLY

1) place the decanter under brew basket, raise top evaporation cover and pour three decanters of water through the top pour-in

screen. water should come through the brew basket as the third decanter of water drains out of water the pour in basin. lf brewer

does not have a pour in opening remove top cover and pour water directly into receiving pan.

2) Adjust timer to deliver desired amount of water (Timer is located behind front acc ess panel).To brew into a regular 60 oz.

Decanter little adjustment should be needed. Turn timer dial clockwise to increase volume of warier ,and counter clockwise

To decrease volume.

3) Brewer is shipped with thermostat turned on, (full clockwise position).Plug or wire in machine to appropriate voltage

Circuit aw noted in the brewers serial tag. Serial tag is located on rear of brewer.

4） Allow 10 to 15 minutes for water in tank to heat to brewing temperature .(Additional water may drip from brew basket on

Initial expansion of water in the tank). This will not occur thereafter.

5) After water hoax reached brewing temperature (thermostat will click off, heatin g noise will stop and green ready light will be

on.) turn lower war mer switch (warmer models). Or lighted rocker switch (airport brewers) to the on position. Depress brew

start switch and run a cycle of water to remove expanded water from tank. (Bre w cycle may be canceled by turning the

rocker switch back to the OFF position.)

6) Run one cycle to check for the proper temperature setting with an accurate thermometer. Take the temperature of this water

at a point below the brew basket opening, at the start of the brew cycle and when the decanter is half full. Recommended

temperature of the water is approximately 195 F.

7) In higher altitude locations (5000 feet above sea level) the thermostat may have to be adjusted lower to prevent boiling.

8) CAUTION: On faucet models the water faucet will dispense hot water when the handle is depressed. The faucet system is

Independent of the brewing system and can be operated dunning brew c ycle. Once brewer is pressurized operate faucet until

Water flows smoothly.

COFFEE PREPARA TION PROCEDURES

1) Place filter into brew basket.

2) Put the proper amount of coffee into the filter.

3) Slide the brew basket into holder.

4) Place empty decanter on warmer located directly under the brew backer and turn corresponding warmer switch to ON position

5) Pour decanter of water through pour-in screen into pour in basin.

6) Hot water will be delivered through the spray head. This distributes the hot water evenly over the coffee bed within the brew

Basket. The coffee brew will drain fro m the brew basket into the decanter below.

1) The resultant coffee brew should be crystal clear and have the desired properties attainable through excellent extraction.

2) TURN OFF WARMER WHEN NOT IN USE. (Red light indicator warmer is on.)

3) To clean brew basket simply remove from brew rails and dump filter into waste basket. The brewing process, as described

Above, can now be started again.

LIMING

To prevent liming problems in tank fittings remove spray head and insert declaiming spring all the wa y into the tank When

inserted into tank properly, no more than ten inches of the spring should be visible at the spray he ad fitting Saw back and forth five or

six times. This will keep fittings open and clear of lime. In hard water areas this should be done everyday. This process takes

approximately one minute. In all areas the spra y he ad should be cleaned at least once a week, Where bad liming has already o ccurred,

a new complete tank assembly may be installed. The tank may be changed in approximately 5 minutes time.
