Integrated Ducting
Integrated ducting interconnects the vehicle’s OEM ductwork to the LG200 HVAC
box. RigMaster Power does not supply any fittings to perform this type of installation.
Custom ductwork is the installer’s responsibility. For further information on this type
of installation contact RigMaster’s Technical Support Center.
Using a Damper Valve
A “T” fitting with a flap to direct the air flow can be used to ensure proper air flow.
This is commonly referred to as a damper valve. Using a “T” fitting without a flap
will allow some air to escape through the OEM HVAC unit. A “Y” fitting may also
be used to direct the air into the vehicles vent system, which will reduce the amount
of air that escapes through the OEM HVAC unit if installed correctly.
