Important Safety Instructions

Read all warnings and instructions in this manual and the instructions included with your operating system or pump. Save these instructions.

WARNING

ELECTRIC SHOCK HAZARD

This equipment must be grounded. Improper grounding, setup, or usage of the system can cause electric shock.

• Turn off and disconnect power at main switch before disconnecting any cables and before servicing equipment.

• Connect only to grounded power source.

• All electrical wiring must be done by a qualified electrician and comply with all local codes and regulations.

SKIN INJECTION HAZARD

High-pressure fluid from dispense 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 dispense 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 Pressure Relief Procedure in this manual, 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.

Pressure Relief Procedure

Relieve pressure in the system following the procedure recommended for your operating system or pump.

Installation

NOTICE

• Electrical ratings must not be exceeded. Overload on a switch can cause switch to fail on the first cycle.

• Never exceed pressure limits. Unit can be operated up to maximum pressure on a limited basis

(i.e., set-up, testing) but continuous operation must be restricted to the designated adjustable range. Excessive cycling at maximum pressure limits could reduce sensor life.
