WARNING
THE UNIT(S) MUST BE MODIFIED OR
INSTALLED BY PERSONNEL WHO ARE
QUALIFIED TO WORK WITH ELECTRICITY
AND PLUMBING. FAULTY MODIFICATION
OR INSTALLATION CAN CAUSE INJURY TO
PERSONNEL AND/OR DAMAGE TO THE
EQUIPMENT. INSTALLATION MUST
COMPLY WITH APPLICABLE CODES.

CAUTION
DISCONNECT ALL ELECTRICAL AND
WATER SERVICE CONNECTIONS BEFORE
WORKING ON STEAMER(S).

2. Remove top and both side covers from the
new unit (upper) to be installed. (See Figure

2)

1. Disconnect existing (lower) steamer
connections. Remove the two screws which
hold the right side (facing the unit) panel.
Remove the panel by sliding it toward the
front of the unit. Unscrew the upper right
mounting bracket which holds the top and
the two screws at bottom of the left side
panel. Remove the cover. (See Figure 1).

Figure 2 - Remove covers from new (upper)
unit.

3. Attach the two provided mounting straps to
the rear of the existing (lower) unit. Use the
unit mounting screws. Mount the straps
using their round holes. (See Figure 3).

Figure 3 - Install straps on lower unit.

If you purchased only the mounting kit, you
must install a “Z” bracket on the bottom rear
of the existing upper unit, using the provided

d” fasteners. Be sure to secure using d”

clearance holes. Note the orientation.

(See Figure I-3a)

Figure 1 - Remove covers from existing

Figure 3a -If you purchased only the

mounting kit, you must install a “Z” bracket
on the bottom rear of the existing upper
unit.

4. Install the top cover you just removed from
the new (upper) unit on the existing (lower)
unit, attaching it to the corner support
brackets on each side. Apply a continuous
¼” bead of silicone sealant all around the top
edge of the cover. (See Figure 4)

Figure 4 - Install top cover from new unit on
lower unit, attaching to corner support
brackets.

5. Working quickly to prevent the silicone from
hardening, install the “Z” bracket to the top
front of the lower unit. Be sure to secure

the bracket using the ¼” clearance holes
on the top panel. (Figure 5)

Figure 5 - Install the Lower Unit “Z” Bracket.

6. Install the inter-unit barrier bracket on the top
of the lower unit. Lower the bracket with the
front edge hanging over the top cover. Slide
it toward the rear, engaging the “Z” bracket
until the bracket contacts the straps on the
back of the unit. Smooth the silicone beads
around the edges. (See Figure 6)

Figure 6 - Install the inter-unit barrier
bracket on top of the lower unit.

7. NOTE: If you purchased a new unit to be
retrofitted into a stacked configuration,
this step does not apply. If you have

purchased only the mounting kit, apply a ¼”
silicone bead around the perimeter. Apply
the bead just in front of the studs, about one
inch from the front edge. (See Figure 7)
