GENERAL NOTES
electricSchwank and EL/ELD Series heaters are furnished with wall/ceiling mount swivel brackets. These brackets
may be discarded when the heater is hung with chains, or other special bracketing.
See sales literature and price list for full listing of models, descriptions, amperages, and voltages. At times, especially
when the mounting height might be quite low, an increased number of smaller heaters can help prevent overheating.
Heaters up to 15 AMPS can be controlled with a simple INF controller. This low cost controller, which is actually an
innite switch, gently pulses the heat on and off at regular intervals when not on full power.
Dual Element Heaters can be wired with our Duplex/Stack Switch, which enables the ability to turn on and off each
element independently, providing for half power/full power capabilities.
For ideal comfort heat, the best solution is to heat from two sides rather than from just one side. However, there are
times when this is not practical.
Coverage areas are approximate dimensions and will vary depending on prevailing and personal comfort levels.
Indoor or well-protected environments will generally exceed average [see charts]. Heaters can provide less than
average coverage in extremely cold/windy conditions.
MAINTENANCE INSTRUCTIONS
Before performing any maintenance, power must be disconnected and the heater cool to touch.
Heater housing, reectors, and heating element can be rinsed with a hose or wiped down with isopropyl
alcohol, acetone, or glass cleaner. Use a clean, scratch-free rag or paper towel. Any oxidation, surface rust, or
discoloration can be removed with a stainless steel cleaner or metal polish on the bare metal surface.
Make sure all water, solvents, or cleaners are removed and the heater is dry before reconnecting the power.
