INSTALLATION
READ THIS CAREFULLY BEFORE STARTING THE INSTALLATION
IMPORTANT:
To enable the installer to make a quality installation and to minimize installation time, the following suggestions and tests should be done before the actual unit installation is started:
CAUTION: Equipment Electrical Damage
DO NOT plug in or energize this appliance until all Installation Instructions are read and followed. Damage to the Brewer will occur if these instructions are not followed.
CAUTION: Unstable Equipment Hazard
It is very important for safety and for proper operation that the brewer is level and stable when standing in its final operating position. Provided adjustable, non-skid legs must be installed at each corner of the unit. Failure to do so will result in movement of the brewer which can cause personal Injury and/ or damage to brewer.
NOTE: Water supply inlet line must meet certain minimum criteria to insure successful operation of the brewer. Bloomfield recommends 1/4" copper tubing for installation of less than 12 feet and 3/8" for more than 12 feet from a 1/2" water supply line.
Unpack the unit. Inspect all components for completeness and condition. Ensure that all packing materials have been removed from the unit.
Verify that the Spray Head Gasket and Spray Disk are properly installed.
LEVELING THE UNIT
Verify that an adjustable leg is installed at each corner of the brewer.
Set Brewer in its operating location. Level the Brewer. A spirit level should be placed on the top of the unit, at the edge, as a guide when making level adjustments.
Level the unit from left to right and front to back by turning the adjustable feet. Be sure all four feet touch the counter to prevent tipping.
PLUMBER’S INSTALLATION INSTRUCTIONS
Brewer should be connected to a POTABLE WATER, COLD WATER line. Flush water line before connecting to Brewer.
DO NOT use a saddle valve with a self-piercing tap for the water line connection. Such a tap can become restricted by waterline debris. For systems that must use a saddle tap, shut off the main water supply and drill a 3/16” (minimum) tap for the saddle connection, in order to insure an ample water supply. Remember to flush the line prior to installing the saddle.
The brewer must be installed on a water line with average pressure between 20 PSI and 90 PSI. If your water pressure exceeds 90 PSI at anytime, a pressure regulator must be installed in the water supply line to limit the pressure to not more than 90 PSI in order to avoid damage to lines and solenoid.
A water shut-off valve should be installed on the incoming water line in a convenient location (Use a low restriction type valve, such as a 1/4-turn ball valve, to avoid loss of water flow thru the valve.

OPERATION
Fig. 4 Brewer Operation Diagram
A. START-UP
IMPORTANT:
Tanks must be full of water before pressing either TANK HEATER SWITCH " elements will be damaged if allowed to operate without being fully submerged in water. Damage caused by operating the brewer without water in the tank is NOT COVERED BY WARRANTY.
ON". Heating
For initial start-up, or if the brewer has not been used for an extended period of time: Be sure spray disk and brew gasket are properly installed in the brew head. Be sure the water supply is properly connected and the water supply valve is turned ON. Be sure faucet water tank drain cap is securely installed. Be sure the WATER TANKS ARE FILLED.
IMPORTANT: Fill the water tanks before pressing heater switches ON:
1. Insert the brew chamber (empty) and place an empty airpot in place under the brew chamber. Be sure heater switches are OFF.
2. Turn main power switch ON.
3. Press "BREW" button and allow brew cycle to complete. Repeat until water flows from the brew head.
4. Place an empty container under the hot water faucet. Hold the faucet open until water flows and all air is purged.
5. Press the tank heater switches ON. The heating elements will begin heating the water in the tanks. When the water in a tank has reached the proper temperature, the associated "READY" light will glow.
6
Page 9
WATER HEATER
Separate coffee brew water and faucet water heater systems are identical. Each heating element is protected from over-temperature by a manual reset hi-limit safety thermostat.
Water temperature is sensed by a thermobulb inserted into each water tank. This temperature signal is fed to the corresponding thermostat, which controls line power to that tank's heating element.
The temperature setpoint is adjustable at the thermostat.
WATER FLOW
AUTOMATIC COFFEE BREW
Pressing BREW button energizes the solenoid valve, allowing water from an external water supply to flow into the basin pan and then into the hot water tank. This forces an identical amount of hot water out of the tank and through the spray head into the brew chamber
The solenoid uses a flow control device so that flow is consistent between 20 p.s.i. and 90 p.s.i.
Length of time the solenoid is open is controlled by the timer.
HOT WATER FAUCET
Water level in the faucet water tank is sensed by an electronic probe. When no water is sensed at the probe, the controller energizes the faucet side of the fill solenoid.
NOTE:
The faucet is gravity fed from a tap in the tank.

BREWING COFFEE
CAUTION: Burn Hazard
Exposed surfaces of the brewer, brew chamber and decanter may be HOT to the touch, and can cause serious burns.
CAUTION: Burn Hazard
To avoid splashing or overflowing hot liquids, ALWAYS place an empty airpot or decanter under the brew chamber before starting the brew cycle. Failure to comply can cause serious burns.
CAUTION: Burn Hazard
After a brew cycle, brew chamber contents are HOT. Remove the brew chamber and dispose of used grounds with care. Failure to comply can cause serious burns.
A. PREPARATION
Place one (1) genuine Bloomfield paper filter in the brew chamber. Add a pre-measured amount of fresh coffee grounds. Gently shake the brew chamber to level the bed of grounds. Slide the brew chamber into place under the brew head.
B. AUTOMATIC OPERATION
BE sure “READY - COFFEE SYSTEM” light is lit.
Place the appropriate EMPTY airpot or decanter in place under the brew chamber.
Press the “BREW” button. The solenoid will open for an amount of time determined by the timer setting, admitting a measured quantity of water into the tank.
Inlet water will displace a like amount of heated water from the coffee brew water tank. The hot water will be forced into the brew head where it will spray over the bed of grounds. Freshly brewed coffee will begin to fill the container under the brew chamber.
When the flow and all dripping stops, the coffee is ready to serve.
Discard the contents of the brew chamber and rinse it in a sink. When the ”READY - COFFEE SYSTEM” light glows, the brewer is ready for another brew cycle.
