Electrical Wiring; Reversing The Electrical Connection - Rheem R95P Installation Instructions Manual

TURN OFF ELECTRIC POWER AT FUSE BOX OR
SERVICE PANEL BEFORE MAKING ANY ELECTRI-
CAL CONNECTIONS. FAILURE TO DO SO CAN
CAUSE ELECTRICAL SHOCK RESULTING IN PER-
SONAL INJURY OR DEATH.
THE CABINET MUST HAVE AN UNINTERRUPTED
GROUND ACCORDING TO THE LATEST EDITION OF
THE NATIONAL ELECTRICAL CODE, ANSI/NFPA70-
OR IN CANADA, THE CANADIAN ELECTRICAL
CODE, CSA-C221 OR LOCAL CODES THAT APPLY.
DO NOT USE GAS PIPING AS AN ELECTRICAL
GROUND. A GROUND SCREW IS PROVIDED IN THE
JUNCTION BOX. FAILURE TO DO SO CAN CAUSE
ELECTRICAL SHOCK RESULTING IN PERSONAL
INJURY OR DEATH.
THIS FURNACE IS EQUIPPED WITH A BLOWER
DOOR SAFETY SWITCH. DO NOT DISABLE THIS
SWITCH. FAILURE TO FOLLOW THIS WARNING
CAN RESULT IN ELECTRICAL SHOCK, PERSONAL
INJURY OR DEATH.
IMPORTANT: The furnace must be installed so that the elec-
trical components are protected from water (condensate).
Before proceeding with the electrical connections, be cer-
tain that the voltage, frequency and phase corresponds to
that specified on the furnace rating plate. For single fur-
nace application, maximum over-current protection is 15
amperes.
Use a separate fused branch electrical circuit containing a
properly sized fuse or circuit breaker. Run this circuit di-
rectly from the main switch box to an electrical disconnect
that is readily accessible and located near the furnace (as
required by code). Connect from the electrical disconnect
to the junction box on the left side of the furnace, inside the
blower compartment. For the proper connection, refer to
the appropriate wiring diagram located on the inside cover
of the furnace control box and in these instructions.
NOTE: The electrical junction box may be moved to the
right side if necessary. A knockout is provided. Seal the op-
posite hole with plug provided.
NOTE: L1 (hot) and L2 (neutral) polarity must be observed
when making field connections to the furnace. The ignition
control may not sense flame if L1 and L2 are reversed.
Make all electrical connections in accordance with the lat-
est edition of the National Electrical Code ANSI/NFPA70
and local codes having jurisdiction.

REVERSING THE ELECTRICAL
CONNECTION (JUNCTION BOX)
If the line voltage electrical needs to be moved to the op-
posite side of the furnace, the following steps should be
taken:
1. The furnace must NOT be electrically connected to line
voltage prior to reversing the electrical connection.
2. Disconnect the wires from the door switch.
3. Remove the junction box from the furnace cabinet wall
by removing the two screws that hold it to the cabinet.
Leave the wires connected to the junction box.
4. Remove 7/8" plug from hole opposite j-box location.
Drill 2 @ 3/16" Ø holes in the jacket. NOTE: Dim-
ples/marks are provided in the sheet metal for correct
drilling location.
