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, and that a rubber foot is installed on each leg.
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 must 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, 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.
The provided water line strainer must be installed in the supply line, between the shutoff valve and inlet tting. Note FLOW arrow marking on strainer body.

ELECTRICIAN’S INSTALLATION INSTRUCTIONS
REFER TO ELECTRICAL SPECIFICATIONS - Page 1 Check the nameplate to determine correct electrical service required for the Brewer to be installed.
IMPORTANT: Before connecting to electricity, make sure
automatic brewers are connected to the water supply.
Models 8742 and 8748 are equipped with a cord and plug.
They require a 115 - 125 volt 20 amp circuit (50/60 Hz, 2 wire plus ground, with NEMA 5-15R or 5-20R Receptacle).
NOTE: This equipment must
be installed to comply with applicable federal, state and local plumbing codes and ordinances.
WARNING:
SHOCK HAZARD
Brewer must be properly grounded to prevent possible shock hazard. DO NOT assume a plumbing line will provide such a ground. Electrical shock will cause death or serious injury.
IMPORTANT:
Supply power must match nameplate for voltage and phase. Connecting to the wrong voltage will damage the brewer or result in decreased perfor­mance. Such damage is not covered by warranty.
IMPORTANT: Do not connect
brewer to electrical power until you are ready to ll the tank. See instructions at left.
606 Owners Manual for 8742-8748 Tea Brewer 2M-76116
IMPORTANT: The ground
prong of the plug is part of a system designed to protect you from electrical shock in the event of internal damage. Nev­er cut off the ground prong nor twist a blade to t an existing receptacle. Contact a licensed electrician to install the proper circuit and receptacle.

OPERATION (continued)
IL1675
WATER HEATER
Water temperature is sensed by a thermobulb inserted into the water tank. This temperature signal is fed to the mechanical thermostat.
The temperature setpoint is adjustable. Heating element is energized by the thermostat.
Excessive temperature will trip the hi-limit safety switch. The hi-limit will automatically reset when the brewer cools.
WATER FLOW
AUTOMATIC OPERATION
Pressing the BREW switch starts the timer, which in turn energizes the solenoid valve. This allows water from an external water supply to ow into the water tank. The incoming water forces heated water out of the tank to perform the brew.
Additionally, a portion of the unheated water is bypassed into the dispenser to dilute and cool the brew. The proportion of water delivered to the brew versus the amount water diverted to dilution is controlled by a restrictor in the bypass line, and an adjustable needle valve in the brew water line.
The solenoid uses a ow control device so that ow is consistent between 20 p.s.i. and 90 p.s.i.
The length of time the solenoid is open is controlled by the timer setting.

Gently shake the brew chamber to level the bed of tea leaves.
Slide the brew chamber into place under the brew head.
B. AUTOMATIC OPERATION
BE sure “READY TO BREW” light is lit.
Place the appropriate EMPTY dispenser in place under the brew
chamber. If a brew-thru lid is used, be sure the bypass opening in the lid is directly under the bypass nozzle.
Press the “BREW” switch. The tea brew 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 tank.
The hot water will be forced into the brew head where it will spray over the bed of grounds. Freshly brewed tea will begin to ll the dispenser. Additionally, a measured amount of cold dilution water will ow from the bypass nozzle into the dispenser.
When the ow and all dripping stops at the end of the brew cycle,
the tea is ready to serve.
Discard the contents of the brew chamber and rinse it in a sink.
When the ”READY TO BREW” light glows, the brewer is ready for another brew cycle.

9. Reconnect brewer to electrical supply and reconnect water
supply.
11. Install the brew chamber without lter paper or grounds.
Run at least three full brew cycles and discard all water generated.
12. Brewer is ready to use.
CAUTION:
CHEMICAL BURN HAZARD
Deliming chemicals are caustic. Wear appropriate protective gloves and goggles during this procedure. Never siphon deliming chemicals or solutions by mouth.
This operation should only be performed by qualied and experienced service personnel.
IMPORTANT: DO NOT spill,
splash or pour water or deliming solution into or over any internal component other than the inside of the water tank.
IMPORTANT: DO NOT allow
any internal components to come into contact with the deliming solution. Take care to keep all internal components dry.
NOTE: Repeat steps 4 thru 5
as required to remove all scale and lime build-up.
NOTE: Normally, silicone
hoses do not need to be delimed. Should deliming hoses become necessary, Bloomeld recommends replacing the hoses.
