•Electrical Connections
1. For wiring connections, refer to Figure 10, 11, 12, or 13.
(NOTE: If installing an EXT series unit, skip to Step 3.)
2. All S series units are equipped for automatic charge control. If these units are to be controlled manually,
insulate the orange umbilical cord wires at the junction box.
3. Check the unit identification label for correct voltages and wattages.
(NOTE: For 120 volt plug-in units, see Figure 2.)
4. Upon completing electrical connections,
move room unit into position and secure
wall support clips (31) to wall support
bracket (1) with 1/4" x 2" bolts provided. Omit this step if installing a unit equipped with a security base.
5. If unit is equipped with leveling legs (17) adjust prior to brick loading. If installing a unit equipped with a
security base (72), this base must be secured to unit prior to loading the brick or putting the unit into
operation. Remove the 5/16" X 1 1/2" bolts from the bottom of the unit. Attach base by inserting these
bolts through the base and screwing back into the same threaded openings they were removed from.
(NOTE: For safety and ease of servicing, label all charging and control circuits in the distribution
panel with the orange panel label provided in the wall support bracket hardware kit (58) .)
3. Attach 1 3/4" x 1 5/8" wall support clips (31) to upper back side of unit using #8 x 1/2" sheet metal
screws provided in hardware kit. Use the carriage bolts to secure the room heating unit to the wall
support bracket.
4. Install field connection junction box. (If installing a 120 volt plug-in unit, skip to Electrical Connections
section.)
(NOTES: 1. Where possible, flush mount using a Sylvania #2002-R-C or equal.
If unavoidable, surface mount using a Steel City #72151 - 1/2 + 3/4
or equal. Mount at floor level. Line voltage field wire must be
rated for 75
0 C minimum.
2. Different wiring methods and unit sizes necessitate larger junction
boxes than specified above. Check State and National Electrical
Codes for proper junction boxes.)
This heater is for use on 120 volts. The
cord has a plug as shown at Figure 4A. An
adapter as shown in Figure 4C is avail-
able for connecting three blade ground-
ing type plugs to two slot receptacles. The
green grounding lug extending from the
adapter must be connected to a perma-
nent ground such as a properly grounded
outlet box. The adapter should not be
used if a three slot grounded receptacle is
available.
