Connect Supply Wiring - Graco SaniForce 26B065 Instructions Manual

Installation

Connect Supply Wiring

All electrical wiring must be done by a qualified
electrician and comply with all local codes and
regulations.
Ensure the equipment is connected to a temperature
controller that limits the operating temperature to 203°F
(95°C) or less.
See Technical Specifications, page 30, for electrical
requirements.
NOTICE
To prevent voltage fluctuations that may result in
equipment damage, use the proper temperature
controller, voltage, wiring, fusing, sensors, and sizing
of electrical connections for your equipment.
1. Ensure that the electrical disconnect (AA) to the
heater is shut off and locked.

2. Remove the fasteners (9), washers (8), cap (7), and
o-ring (6) to access the electrical wiring
compartment.
3. Insert electrical wires through the electrical wiring
port (C).
4. Connect wires to terminals. See Electrical
Schematics, starting on page 23.
NOTE: Conductors and terminals used for supply
connection must be suitable for 221°F (105°C) or
greater.
NOTE: Heater terminals are 1/4-20 thread. Torque
to 75 in-lb (8.5 N•m).
NOTICE
To prevent equipment damage, do not torque
terminal nuts more than 75 in-lb (8.5 N•m).

5. Install the o-ring (6), cap (7), washers (8), and
fasteners (9). Torque fasteners (9) to 20in-lb
(2.2 N•m). See Torque Sequence, page 22.

Connect Thermocouple
A Type J thermocouple is permanently installed in the
system. Connect the thermocouple wire (F) to your
temperature controller (required, not supplied).
NOTICE
Do not exceed the maximum operating temperature
of 203°F (95°C). Operating the equipment outside of
these conditions can result in premature heater
failure, heater short, or potentially hazardous heater
burnout.
Install a second temperature sensor (required, not
supplied) as close to the fluid outlet port as possible to
measure fluid outlet temperature.
Connect Over-Current Protective Devices
Prior to powering on, install external over-current
protective devices (required, not supplied) to the
equipment. See Technical Specifications, page 30, for
electrical requirements.
