Installing the Power Unit
This section describes how to
install
, but not make the connections to, the Power Unit for your Lift.
An Electrician is
not
needed to install the Power Unit; one is required to connect the Power Unit to its
power source.
The Power Unit
must
be installed on the Power Post; attach it to one of the two Mounting Brackets,
whichever is more convenient for the installation.
Important: Many people install the Flex Tube Bracket Plate and/or the Zero Angle Bracket at the
same time as they install the Power Unit. Read Installing the Flex Tube and
Installing the Pushbutton Air Valve for more information to see if this makes
sense for your installation.
⚠ DANGER Risk of explosion: The Power Unit has internal arcing or parts that may spark and
should not be exposed to flammable vapors. Never expose the Power Unit motor
to rain or other damp environments. Damage to the motor caused by water is
not
covered by the warranty.
Tip The Power Unit is heavy. We recommend you have one person hold the Power Unit while
another person bolts it in place.
The following drawing shows how to attach the Power Unit to the Power Post.
