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

manual where applicable.

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.

1. Disconnect power.
