Optional Accessories
Dirty Filter Sensor (Magnehelic Gauge)
Dirty filter sensor monitors pressure drop across the
exhaust air filters. Visual gauge on the side of the
plenum cabinet indicates the pressure across the filter
section. Periodic inspection is necessary to determine
whether filters need to be replaced.
Vapor Tight Lights
Vapor tight lights provide light to each of the
compartments in the energy recovery plenum. The
lights are wired to a junction box mounted on the
outside of the unit. The switch requires a separate
power source to allow for power to the lights when the
unit main disconnect is off for servicing.
Electrical Package
The electrical package consists of a switch and GFCI
receptor mounted in a two gang, “in use” NEMA-
3R rated box with cover plate. This box would be
mounted at the factory near the ERS plenum access
doors.
The GFCI is rated for 15A, 125VAC and is provided
with SafeLock™ Protection. This feature denies
power if the GFCI is incorrectly wired or if the GFCI
is damaged and protection is lost. The GFCI is also
equipped with a trip indicator light to easily identify
tripped condition. Receptor uses a NEMA 5-15 R
configuration.
Supplied switch is industrial extra heavy duty grade
with back and side wiring. The switch has a rating of
20A, 120/277VAC and single pole. The switch comes
from the factory pre-wired to lights within ERS plenum
section.
Electrical wiring for power to the electrical panel is to
be installed by a licensed electrician in compliance
with all local and national codes.
