Installation - Groen TDBC 20C Operator's Manual

WARNING
INSTALLATION OF THE KETTLE MUST BE
DONE BY A CERTIFIED ELECTRICIAN OR
AUTHORIZED REPRESENTATIVE QUALIFIED
TO WORK WITH ELECTRICITY. IMPROPER
INSTALLATION CAN RESULT IN INJURY TO
PERSONNEL AN/OR DAMAGE
TO EQUIPMENT.
CAUTION
BEFORE ANY ELECTRICAL CONVERSION,
VERIFY THAT THE BRANCH CIRCUIT
WIRING IS ADEQUATE TO HANDLE ANY
INCREASE AMPERAGE REQUIREMENTS.
REFER TO THE ELECTRICAL
SPECIFICATIONS LISTED BELOW.
The TDB/TDBC Kettle is provided with complete internal wiring and is ready for
immediate connection. Wiring diagrams are provided in this manual and on the inside
of the control housing service panel. Any mechanical or electrical changes must be
approved by Unified Brand's Engineering Department.
The completed unit has been operated at the factory to test all controls and heater
elements.
1. Set the kettle in place and level it. The base should be securely fastened to a
table or work surface. Four 3/8"-16 N.C. threaded couplings are provided in the
base of unit. Installation under a ventilation hood is recommended.
2. Once the unit is anchored to a mounting surface, apply a small bead of silicone
caulk around the perimeter of the kettle base and seal the joint.
3. Provide electrical power as specified on the electrical information plate
attached to the equipment. Observe local codes and/or The National Electrical
Code in accordance with ANSI/NFPA 70 - (current edition).
4. Standard equipment is shipped ready for 208V, 3-phase or 480V, 3-phase
operation. Refer to the wiring diagram located on the inside cover of the
control box and the instructions below for conversion to single-phase
operation. A jumper wire and "conversion" label are included with the unit.
They can be found in a plastic bag attached to the trunnion assembly inside
the control box.
a. For conversion from 208V, 3-phase to 208V or 240V 1-phase or
480V, 3-phase to 480V, 1-phase:
i. Verify that the branch circuit wiring is adequate for any
increased amperage requirements (see table on page 8).
ii. For 240V 1-phase only, enlarge electrical inlet opening for
1" conduit fitting. Use a 1" sealtite conduit fitting.
iii. Refer to wiring diagram for field conversion.
iv. For 240V 1-phase only, pull lead from 208V tab on control
transformer and insert on 240V tab (See photo on page 8).
v. Complete "conversion label" (supplied in bag) and adhere it
to the control box near the UL dataplate.
b. For conversion from 208V, 3-phase to 240V, 3-phase:
i. Verify that the branch circuit wiring is adequate for any
increased amperage requirements (see table on page 8).
ii. Pull lead from 208V tab on control transformer and insert
on 240V tab. (See photo on page 8)
iii. Complete "conversion label" (supplied in bag and adhere it
to the control box near the UL dataplate).
