Determining Door Orientation
BeforeinstallingtheUnirose/ChassisAssemblyyoumust
determine if your door is a Right or Left hand door. This is
accomplished by noticing hinge location when facing the
Push side of the door. If the hinges are on the left, it's a left
hand door and if on the right, it's a right hand door. The
assembly is set at the factory for a left hand door.
Set Up for a Right Hand Door
Remove the 2 screws that secure the chassis to the Push
Uniroseusinga#2PhillipsScrewdriver.RotatetheChassis

4 and 10 O'clock positions. If this is a 2" door installation
(L3) then you must also reinstall the Spacers between the
ChassisandUniroseatthe4and10o'clockpositions.

Mark your drill hole with pencil,
repeat on other side.
