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

IL1697

IL1618

Fig. 4 Brewer Operation Diagram

IMPORTANT:

Tank must be full of water before connecting brewer to electrical power.

For initial start-up, or if the brewer has not been used for an extended period of time:

Heating 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.

BEFORE plugging the brewer into a receptacle, or otherwise connecting brewer to electrical power ThE WaTER TaNK MuST BE FIllED. Place an empty decanter under the brew head. Lift

the pour-over cover then pour warm tap water into the pour-over

opening until water ows from the brew head. When water stops

dripping from the brew head, empty the container. Once the tank is full of water, connect the brewer to electrical

power. The heating elements will begin heating the water in the tank. When the water has reached the proper temperature, the “READY To BREW” light will glow.

START-UP

•

Be sure spray disk and brew gasket are properly installed in the

brew head.

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.
