INSTALLATION INSTRUCTIONS
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 25 feet and 3/8” for more than 25 feet from a 1/2” water supply line.
REFER TO EXPLODED VIEWS PAGES 18 thru 22 FOR COMPONENT NAMES/NUMBERS
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 (#33) and Spray Disk (#34) 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, 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.

WARNING
NSF requires that the brewer be able to be moved for cleaning
underneath. A ex line or loops of copper tubing will satisfy this
requirement. See Figure 2 below.
Fig. 2 Water Supply Installation New-style shown
In some areas, local codes require a backow preventer (check valve) to be installed on the inlet water line. If a backow
preventer is used, you must install a water hammer arrester
in the incoming line, between the backow preventer and the
brewer inlet, as far away from the brewer as space will allow. This will relieve the excessive back pressures that can cause faucet leaks and solenoid malfunctions.
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.
All models (except 8574) 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).
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.
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: Do not connect brewer to electrical power until
the tank is lled with water.
Pour water into the pour-over
opening until water ows from
the brew head.
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.
2M-75804-611 Koffee-King 8900 Series Brewer
Model 8574 must be wired by an electrician, and requires a 115/230V 20A circuit (50/60 Hz, 2 hot legs / 1 neutral leg, plus ground). Remove front panel to gain access to terminal block. Green terminal must be connected to a suitable building ground.
Circuit must be capable of 3800 Watts. See gure 3 at right.
IMPORTANT: Wiring must be installed in approved solid or
exible conduit, and must be secured to the brewer with a strain
relief (to be provided by the installer).

OPERATION (continued)
WATER HEATER
Water temperature is sensed by a thermobulb inserted into the water tank. This temperature signal is fed to the thermostat, which controls line power to the heating element.
The setpoint temperature is adjustable at the thermostat.
The element is protected from over­temperature by a hi-limit thermostat.
WATER FLOW
POUR-OVER FEATURE
Pouring any amount of cold water into the pour-over opening and into the basin pan forces an identical amount of hot water out of the tank and through the spray head into the brew chamber.
AUTOMATIC OPERATION
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
HOT WATER FAUCET
The faucet water coil is submerged in the hot water tank and draws heat from the brew water. Water going to the water coil is not controlled by the solenoid valve.
The faucet is at supply water pressure any time the faucet shut-off valve is OPEN.
