Equipped with Option 46 Automatic Refill Option 39 Low Water Cut-Off System

General Description

This unit is a high temperature hot water boiler. It consists of a non-pressure, vented water compartment into which is installed an electric immersion heater thermostatically controlled through a contactor relay, to keep the water always at the desired brewing temperature. Automatic refill maintains water level in water compartment. All control system components are enclosed in a stainless steel housing on the right end of the urn:

A master ON-OFF switch shuts off entire unit, including heater circuit: Separate low water cutoff system protects heater and entire unit from damage.

Installation

1.IMPORTANT TO ALLOW 6" CLEAR SPACE TO RIGHT ON CONTROL BOX FOR ACCESS. Urn should be level, both front to back and left to right.

2.CONNECT WATER LINE. 3/8" NPT water inlet located at right end. Provide shutoff valve and union in supply line near urn. Cold or hot water may be used, but hot water will give greater gal- lon per hour capacity. We strongly recommend the use of copper or aluminum tubing to provide flexibility and avoid strain on the unit. 3/8" O.D. Tubing is recommended.

3.CONNECT URN TO ELECTRIC POWER. Check to be sure that name plate marking of voltage phase and number of wires matches supply lines. Remove cover on control housing. Terminal block for line connections located in housing on right end. See drawing, as required. It is rec- ommended that a fused disconnect switch be installed near urn. Urn body must be grounded either through metallic conduit or else by means of ground wire. An experienced electrician should be responsible for the installation of the unit, and its associated supply line. NOTE: Neutral wire required on all single phase and on 208 volt 3 phase power supplies to operate 120volt AC control circuit. Do not replace cover until completion of installation.

4.FILL WATER COMPARTMENT. Turn on water supply and electric service to urn. Turn master switch on. Do NOT turn on thermostat until water shows in gauge glass (approximately 6 min- utes). When water shows, remove adhesive WARNING label from thermostat knob. Turn thermostat knob maximum clockwise to BREW position. Pilot light over knob should light showing heater power on. Water compartment will fill automatically to stop-full level, and should reach operating temperature approximately 45 minutes later. When the pointer on thermometer approaches the "W" in the blue BREW zone, unit is ready for operation.

5.REFILL RATE ADJUSTMENT. To gain maximum capacity of the boiler, and shorten heat recovery time, adjust the water inlet flow regulator (located inside the control box) according to the chart provided. Turning the threaded adjustment shaft clockwise increases the flow rate, counterclockwise will decrease it.
