XIII. Electrical
A. General
Install wiring and electrically ground the appliance in
accordance with authority having jurisdiction or, in the
absence of such requirements, follow the National
Electrical Code, NFPA 70, and/or Canadian Electrical
Code Part 1, CSA C22.1.
1. A separate electrical circuit must be run from
the main electrical service with an over-current
device/disconnect in the circuit. A service switch
is recommended and may be required by some
local jurisdictions. Install the service switch in the
line voltage "Hot" leg of the power supply. Locate
the service switch such that the appliance can be
shut-off without exposing personnel to danger in
the event of an emergency.
B. Power Requirements
1. Nominal appliance current draw is provided in Table
35. These values are for planning purposes only
and represent the appliance's maximum power
consumption.

Electrical Shock Hazard: Ensure all electrical
connections are disconnected before attempting
installation or service of electrical components or
connections of the appliance or building. Lockout
all electrical boxes with padlock once power is
turned off.
!
Electrical Shock Hazard: Failure to properly wire
electrical connections on the appliance may result
in serious physical harm.
Electrical power may be from more than one
source. Make sure all power is off before attempting
any electrical work.
Each appliance must be protected with a properly
sized over-current device.
Never jump out or make inoperative any safety or
operating controls.
The wiring diagrams contained in this manual
are for reference purposes only. Each appliance
is shipped with a wiring diagram attached to the
front door. Refer to this diagram and the wiring
diagram of any controls used. Read, understand
and follow all wiring instructions supplied with
the control.
All wires, wire nuts, controls etc. are installer
supplied unless otherwise noted.
When making low voltage connections, make sure
that no external power source is present in the
thermostat or limit circuits. If such a power source
is present, it could destroy the microprocessor
control. One example of an external power source
that could be inadvertently connected to the low
voltage connections is a transformer with old
thermostat wiring.
To obtain total system power consumption add all
selected circulator and component current draws
Label all wires prior to servicing controls. Wiring
errors can cause improper and dangerous
operation. Verify Proper operation after servicing.
