CONNECT URN TO ELECTRIC POWER. Check to be sure that the nameplate mark-
ing of voltage, phase and the number of wires matches supply lines. Remove cover on
control housing. The terminal block for the line connections is located in the housing
on the left end. See drawing, as required. It is recommended that a fused disconnect
switch be installed near urn. The urn body must be grounded either through metallic
conduit or else by means of ground wire. An experienced electrician should be respon-
sible for the installation of the urn, and its associated supply line. NOTE: Neutral wire
required on all single phase and on 208 volt 3 phase power supplies to operate 120 volt
AC control circuit.
On single phase, 2 wire service (no neutral) or 3 phase 3 wire service (no neutral) 120
volt AC power to operate control circuit must be supplied as circuit. Do not replace
cover until completing installation start-up.

heater power on. Water compartment should reach operating temperature approxi-
mately 45 minutes later. When the pointer on thermometer approaches the “W” in the
blue BREW zone, urn is ready for automatic operation.
