INSTALLATION
Read carefully and under stand the installation manual for the leveler and or the restraint in
to be installed in conjunction with the Centra Power manual.
Read carefully and under stand the Centra Power Lay out drawing. The drawings will have
all the required information on hose charts, fluid capacity and location of the mid run and end
run valve blocks.
The Centra Power pump station is typically located in the center of the dock levelers with
even amount of doors on each side. The pump station should be mounted a minimum of 72”
off the finished floor (out of the way of damage).
The Pump Station Control Box should be mounted a minimum of 72” off the finished floor
next to the Pump Station.
Hose installation can be started at the pump station or at the furthest dock leveler. Note:
when installing hose or valve blocks always keep shipping caps on fittings until hoses are
connected to the .
Typical installation the pressure lines will have #8 JIC fittings and 1/2 dia. lines. The returns
lines if without restraints will be #8 JIC with 1/2 dia. hose. Pay close attention not to allow
lines to be swapped between pressure and return. When levelers with Power Hooks are
installed the return lines will have #10 JIC and 3/4 dia hose.
When all hoses valves and hydraulic connections are made and tight. Fill the reservoir with
oil (see page 15).
Fill the Pump Station reservoir (capacity 12 gals) to the full mark (See page). Starting from
the furthest dock from the pump station, run all the levelers and the restraints through several
cycles to purge all the air out of the system. Once all levelers have been cycled several
times have all the levers in the below dock position. Note: On Centra Power Systems were
both motor must run all the time the rotation must be checked. To check rotation run only one
motor at a time the levelers will work but run slow.
