ORION Commercial 'LULA' Elevator - Advanced Lift Solutions

5.0 HYDRAULIC INSTALLATION
When the EPV-12 is installed, the oil line must have a minimum
¾” dia. with a ½” dia. NPT adapter at the jack.
Steel Piping
Before connecting the oil line, clean it out
by placing the jack end of the oil line into
a bucket and running the pump enough to
flush out a cup or two of oil. DO NOT PUT
THIS OIL BACK IN THE TANK!
Make sure the pipe and fittings have the
proper rating. Most jurisdictions require
minimum Schedule 40 oil line and fittings.
When routing the oil line to the hydraulic jack
assembly, always minimize the number of
90 o bends in the line. Each 90 o bend causes
pressure loss and increases the noise level,
as the elevator operates.
Insulate the oil line where it passes through
the hoistway wall to prevent vibration.
The code permits the use of hydraulic
hose within the machine (pump) room. It
is recommended practice to install a short
figure 48 Steel Piping
length of hydraulic hose from the gate valve
on the pump to where the steel oil line starts
to pass through the hoistway wall. This will
help reduce the noise level from the pump/motor operation.
1) The steel oil line must be securely supported to reduce noise and eliminate vibration
that may loosen or damage fittings and connections. Support the steel pipe on the
upstand post and clip it to the hoistway wall using insulating clips (Figure 48).
2) For a 90o elbow, a ½” male NPT to ½” male NPT is suggested. Remember, all fittings must
be high strength (minimum
Schedule 40).

3) For long runs of pipe,
minimize the number of 90 o
bends by using 45 o and 30 o
fittings, wherever possible.
