WATER PIPING:
REVERSIBLE WATER CONNECTIONS: This heater is designed so that it can be installed with the water connections located on either the
right or left side. Heaters are factory-shipped with right-side water connections. To modify the heater to have water connection on the left side
of the unit, a single screw and panel must be removed and rotated. To complete this alteration, follow the instructions below and reference Fig-
ures 1 and Figure 13 as needed.
Before beginning, be aware that regardless of the arrangement of connections in the installation, the electric junction boxes and exhaust will
ALWAYS be opposite from the water connections.
1. Remove the single screw securing the top access panel to the cabinet
top (see Figure 12).
2. Lift the front lip of the top access panel several inches. The front of the
panel is where the user interface is located and the same side the
screw was removed from in step 1.
3. With the front of the top access panel elevated, slide the panel toward
the rear of the unit until the tabs holding the rear side down are disen-
gaged from the cabinet top.
4. Carefully lift the top access panel free of the unit, ensuring excess
tension is not placed on the ribbon cable attached to the ignition con-
trol board inside the heater cabinet, and rotate it 180 degrees so that
the user interface is now on the opposite side of the heater.
5. Secure the top access panel to the heater in the new orientation by
installing the screw removed in Step 1 in the new location.
NOTICE: The heater is for use with pool and spa/hot tub water furnished by municipal water distribution systems only. Do not use with
mineral water, seawater (PPM > 5000), or other non-potable waters which invalidate the warranty. Do not install any restriction in the wa-
ter pipe between the heater outlet and the pool/spa with the exception of a three-way switching valve, in-line chlorinator and/or chlorinator
check valve.
