Vapor Tight Lights
Vapor tight lights provide light to each of the compartments
in the energy recovery unit. The lights are wired to a switch
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.
OPTIONAL ACCESSORIES
Service Outlet
120 VAC GFCI service outlet ships loose for field
installation. Requires separate power source so power
is available when unit main disconnect is turned off for
servicing.
CO2 Sensor
This accessory is often used to provide a modulating control signal to a variable frequency drive to raise and
lower airflow in relationship to the CO2 levels in the space. This strategy is often referred to as Demand Control
Ventilation and provides further energy savings to the system. Follow instructions supplied with sensor for
installation and wiring details.
