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 ampu-
tation. 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

NOTICE
• Electrical ratings must not be exceeded. Over-
load on a switch can cause switch to fail on the
first cycle.
• Never exceed pressure limits. Unit can be oper-
ated 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.
