The disconnect and line circuit protection to be provided by
customer. Line circuit protection to be 115% of motor full load
current at maximum pressure of application (see Figure 1).

4.4 Oil Level
Check the pump oil level prior to start-up. If oil level is low, remove
the oil fi ll plug (A) from the cover plate (see Figure 2) and add oil
as required. The reservoir is full when the oil level is as shown in
Figure 4.

Advance hose to valve port "A".
Retract hose to valve port "B" (if applicable).
Gauge to valve port "GA", "GB", or "GP".
("GA" measures "A" port pressure, "GB" measures "B" port pressure,
"GP" measures pump pressure down stream of system check).
5.0 OPERATION
1.
Check the oil level of pump and add oil if necessary.
2.
Make sure that the reservoir air breather has been installed.
