OPTIONS AND ACCESSORIES

Remote Control Enclosures — RMB Series
RMB Series remote control enclosures are available in various
configurations for use with strip heaters. Remote control
enclosures locate controls away from the heat of the unit,
increasing the life span of the controls. All models are built in
accordance with CE standards with switches, indicator lights,
and wiring. Consult the factory for type and location of RMB
Series controls for enclosure.
NOTE: RMB Series remote control enclosures require one
remote control enclosure per strip heater.
1. Determine the area to mount the RMB box.
IMPORTANT NOTE:
Remote mounted enclosures and control switches must be
installed in a cool, dry location as far away from any heat zone
as possible. Do not mount enclosures or switches directly on,
under, or above unit. Do not mount enclosures or switches
in direct contact with any heated surface or near any steam
generating equipment.
