ELECTRIC ELEMENTS
Electric resistance heating elements are rated for 240 VAC or 208 VAC. Power to each element must be supplied by a UL/CSA listed individual two-pole breaker with a common trip.
1.) Mount the electric heating elements in the 1" NPT fittings in the element box. Each element has an O-ring for proper sealing into its threaded plug. In addition, use Teflon tape to seal the threads of the elements.
DO NOT USE PIPE DOPE COMPOUNDS ON THE TREADS WHEN INSTALLING THE ELECTRIC ELEMENTS. The pipe dope lubricates the o-rings and may cause them to
dislodge, which may cause a leak.
2.) Install the elements in the lowest fittings possible to maximize storage. Plug any unused fittings with 1" NPT plugs (use pipe dope or teflon tape to seal).
ONLY CONNECT STEEL CONDUIT TO THE ELEMENT BOX AS IT MAY REACH TEMPERATURES IN EXCESS OF 200°F.
3.) Fill the tank with enough water to cover the elements and test for leaks.
ONLY OPERATE THE ELECTRIC ELEMENTS WHEN SUBMERGED IN WATER. If they are turned on out of water they may burn out and require replacement.
ELECTRIC ELEMENT BOX
The tank-mounted junction box comes with a high-temperature insulation gasket, UL/CSA listed box, box cover, fasteners and labels.
