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.
Bloomeld 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

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.
