Power Door Assembly

The ability door associates consists of:

one. Unit of measurement operation light, ON-OFF switch, and door attach

ment knob—all installed on door comprehend.

ii. Door base plate contains a solid-state power pack that

converts 120 VAC to high voltage DC (A240V Conversion
Kit, P/North 31KAX900---001-- is available). All wiring
mounted internally. A line-voltage disconnect (male person plug)
and high-voltage jitney-bar are mounted on the base plate
externally. 4 screws must be removed to betrayal the

furnace air blower, is controlled by an ON-OFF power switch.
With the power switch ON (assumingpower door in placed and
air blower operating), 120 VAC ±10% single-phase, lx-Hz power
is applied to the ability pack (240V Conversion Kit transformer
converts 240V to 120 V Ac). Output of the power pack assembly

is approximately 7300 VDC.

Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without detect and without incurring obligations.
