MAGNETIC CONTACTOR (HSE Models Only)

The magnetic contactor(s) is a heavy-duty resistive load type rated for 100,000 cycles. The contactor supplies power to the heating element(s) based on the resistive load (non-inductive) of the heater only when the thermostatic switch is engaged, thereby pulling in the contacts until the desired temperature is reached. At this point, the contacts will drop out, which in turn disconnects power from the elements.

OUTER SHELL AND INSULATION

The tank is encapsulated in 2-inch thick polyurethane foam insulation. The insulation is protected by a high impact non-corroding colorized composite protective jacket.

DRIP PAN (Optional)

A drip pan assembly may be supplied as an option with the unit. It is designed to mount directly beneath the water heater as shown in the sketch on page 4.

SWAY RESISTANT MOUNTS (Optional)

Optional sway resistant mounts may be supplied to further secure the tank from longitudinal movement. Additional 3/8” diameter threaded rods (not supplied) are fastened into additional nuts that are welded to the support mount.
