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 procedures-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.
1. Warnings
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 hands, 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 coupling daily. Replace worn or damaged parts immediately.
FIRE AND EXPLOSION HAZARD
When flammable fluids are present in the work area, such as gasoline and windshield wiper fluid,
be aware that flammable fumes can ignite or explode. To help prevent fire and explosion:
Use equipment only in well ventilated area.
Eliminate all ignition sources, such as cigarettes and portable electric lamps.
Keep work area free of debris, including rags and spilled or open containers of solvent and
gasoline.
Do not plug or unplug power cord or turn lights on or off when flammable fumes are present.
Ground all equipment in the work area.
Use only grounded hoses.
Stop operation immediately if static sparking occurs or you feel a shock. Do not use
equipment until you identify and correct the problem.
Keep a working fire extinguisher in the work area.

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.
Turn off all equipment and follow the Pressure Relief Procedures 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. Alterations or modifications may void agency approvals
and create safety hazards.
Make sure all equipment is rated and approved for the environment in which you are using it.
Use equipment only for its intended purpose. Call CPI for information.
Route hose and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.
Do not kink or over bend hoses or use hoses to pull equipment.
Keep children and animals away from work area.
Comply with all applicable safety regulations.
PERSONAL PROTECTIVE EQUIPMENT
Wear appropriate protective equipment when in the work area to help prevent serious injury,
including eye injury, hearing loss, inhalation of toxic fumes, and burns. This protective equipment
includes but is not limited to:
Protective eye wear, and hearing protection.
Respirators, protective clothing, and gloves as recommended by the fluid and solvent
manufacturer.

Installing the Box
Grounding
The equipment must be grounded to reduce
the risk of static sparking. Static sparking
can cause fumes to ignite or explode.
Grounding provides an escape wire for the
electric current.
Ensure the lubricator is properly grounded as
the pump is grounded through the mounting
screws.
Mounting the Box
Note:
When installing the P55U Lubricator box always
mount it to a rigid support or frame.
The Lubricator may be driven by the rotating
source of the engine or compressor or an electric
motor.
Be careful to accurately align the lubricator to the
drive shaft. Misalignment will cause stress to the
drive shaft and will damage the pump seals and
bearings.

2. Installation Instructions
3. Operating Instructions
1. Before running the lubricator ensure that the drive shaft, pump, and accessories are correctly specified
for the chosen application.
2. Securely mount the lubricator assembly.
3. Make sure drive shaft is connected and properly aligned.
Before start up the lubricator must be filled to the half way mark of the sight glass with the specified
lubricating oil for the operating conditions. (Minimum oil level is at top of camshaft. If oil falls below refill
to appropriate oil level.)
5. Fully prime the pump as described in P-55U Pump User Instructions before operating the lubrication
system.
6. Once running observe the complete system to ensure proper operation of all components. For trouble
shooting of individual components refer to the individual part operations manual.

Max Lubricator Cam Shaft speed, 35RPM
Refer to your manufacturer’s specific instruction manuals to ensure your box and
lubrication system are rated for the selected pressure.
Suitable for Use with Petroleum and Synthetic Base Lubricants
Minimum Oil Viscosity 90 SUS
Maximum Oil Viscosity 8000 SUS
Based on 500 SUS oil at 70°F ambient. Heavier oil will produce fewer but larger drops.
When approaching maximum outputs, some oils will stream rather than form drops in
sight glass.
