Appro pri at e power cord acces so ry ki t is d et erm i ned
by the voltage, and amperage of the branch circuit.
Th e un i t d o es n ot come with a po wer co rd (or
hard wire kit). An accessory power cord k i t m us t
be ordered t o connect the unit to the outlet. If the
uni t is to be hard wired, an access ory hard wire kit
must be ordered.
IMPORTANT: For 265V units, if power cord
accessory option is selected, the cord is only 18”
long and must plug into the accessory electrical
265V subbase.
Be sure that your outlet matches the appropriateblade

Grounding
For safety and protection, the unit is grounded
through the service cord plug or through separate
ground wire provided on hard wired units. Be sure
that the branch circuit or general purpose outlet is
grounded.
VOLTAGE SUPPLY
Check voltage supply at outlet. For satisfactory
results, the voltage range must always be within the
ranges found on the data i nformation plate.
Cord--connected
Units
The 250-- v field supplied outlet must match the plug
for t he s tandard 208/230 --v unit s and be withi n reach
of th e servi ce cord . The st an dard co rd--con n ect ed

and fuse type.
Power Cord
Protection
The power cord for 230/208v units provide power
cord fire p rot ect i on . Unit power automatically
disconnects when unsafe conditions are detected.
Power to the unit can be restored by pressing the reset
buttononplughead.
Upon completion of unit installation for 230/208V
models, an operational check should be performed
using the TES T/RESET buttons on the plug head.
NOTE: The 265v models do not incorporate this
feature as they require use of the electrical subbase
accessory.
