4.0 INSTALLATION

4.1 Hydraulic Connections

Use 1 1/2 wraps of teflon tape (or suitable thread sealant) on all
threads, leaving the first complete thread free of tape to ensure
that the tape does not shed into the hydraulic system, causing
damage. Trim loose ends.

WARNING: To ensure proper operation, avoid kinking or
tightly bending hoses. If a hose becomes kinked or
otherwise damaged, it must be replaced. Damaged

hoses may rupture at high pressure, causing personal injury.

PUJ-1200B/E, PUJ-1201B/E Models (Figure 2)

1. Remove the shipping plug from the .250-18 NPT gauge port

(A) on top of the control valve.

2. Install a 0-15,000 psi (1035 bar) pressure gauge into the

gauge port (A).

3. If required, thread hydraulic hose in the .375-18 NPT valve

outlet port (B).

4. Connect a return line by threading a hose into the return to

tank port (C).

PUJ-1400B/E, PUJ-1401B/E Models (Figure 3)

1. Remove the shipping plug from the valve advance port (D).

Install a gauge adaptor into the .375-18 NPT advance port (D).

2. Install a 15,000 psi (1035 bar) pressure gauge in the gauge

adaptor top port.

3. Install a hydraulic hose into the gauge output adaptor end

port (.375-18 NPT). Connect the hose half coupler to the
cylinder advance half coupler. Firmly hand tighten the coupler
collar. DO NOT use tools to tighten the coupler halves.

4. If using double-acting circuit install hose into the retract port

(E) on the control valve. Connect the hose half coupler to the
cylinder retract half coupler.
