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 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 nal 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.
Bloomeld 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 ush 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 ow thru the
valve. A water line strainer should be installed in the supply line,
between the shutoff valve and inlet tting. Install with FLOW
arrow marking on strainer body pointing toward brewer.

OPERATION (continued)
IL2327
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 ow 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 ow control device so that ow is consistent between 20 p.s.i. and
90 p.s.i. Length of time the solenoid is open is
controlled by the timer.
Fig. 5 Heat Control Diagram
A second brew cannot be initiated until delay time (set by DELAY section of timer) is completed
HOT WATER FAUCET
Water level in the faucet water tank is sensed by an electronic probe. When no water is
915 2M-Z15131 Owners Manual for 8783MCD
sensed at the probe, the controller energizes
the faucet side of the ll solenoid.
NOTE:
If water is not detected at water level probe for two minutes, unit will shut down.
NOTE:
The faucet is gravity fed from a tap in the faucet water tank.
