Warnings
The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When
these symbols appear in the body of this manual, refer back to these Warnings. Product-specific hazard symbols and
warnings not covered in this section may appear throughout the body of this manual where applicable.
WARNING
SKIN INJECTION HAZARD
High-pressure fluid from dispensing device, hose leaks, or ruptured components will pierce skin. This
may look like just a cut, but it is a serious injury that can result in amputation. Get immediate surgical
treatment.
• Do not point dispensing device at anyone or at any part of the body.
• Do not put your hand over the fluid outlet.
• Do not stop or deflect leaks with your hand, body, glove, or rag.
• Follow the Pressure Relief Procedure when you stop dispensing and before cleaning, checking, or
servicing equipment.
• Tighten all fluid connections before operating the equipment.
• Check hoses and couplings daily. Replace worn or damaged parts immediately.
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
• Do not operate the unit when fatigued or under the influence of drugs or alcohol.
• Do not exceed the maximum working pressure or temperature rating of the lowest rated system
component. See Technical Data in all equipment manuals.
• Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all
equipment manuals. Read fluid and solvent manufacturer’s warnings. For complete information
about your material, request MSDS from distributor or retailer.
• Do not leave the work area while equipment is energized or under pressure. Turn off all equipment
and follow the Pressure Relief Procedure when equipment is not in use.
• Check equipment daily. Repair or replace worn or damaged parts immediately with genuine
manufacturer’s replacement parts only.
• Do not alter or modify equipment.
• Use equipment only for its intended purpose. Call your distributor for information.

Installation
Installation
The USP Valve should be ready to install in your system. It has been factory-tested and should not require
any additional modification.
As long as lubricant is supplied under pressure, the
valve will continue to operate . Whenever lubricant flow
ceases, the valve pistons stop. When flow resumes, it
will start again at the same point in the discharge cycle.
NOTE: The manufacturers of the machine tool and its
component bearings should be consulted to ensure that
the ISO 18/14 cleanliness level is adequate.
Outlet Adapters
Each block ships with the correct number of outlet
adapters. Install one adapter into each open outlet port.
Outlet adapters have standard threads for interfacing
with tube fittings.
NOTICE
Supplied outlet adapters are required for full functionality and testing.
3. Plug outlet adapter (b) with user supplied plug (c) to
double the output volume.
Lubricant from the plugged outlet adapter is redirected
to the next outlet on the USP divider block flowing in a
clockwise order, following direction arrows (A) stamped
on block (see F
For example in
ging 2 outlet adapters will triple the amount of lubricant
at the next outlet. This outlet will include the output of
plugged outlets that are now rerouted as well as it’s own
output.
