SAFETY FIRST!
SAVE THESE INSTRUCTIONS!
WARNING!
•This equipment is intended for use with Liquefied Petroleum Gases (LP-GAS). Equipment is not equipped with an overfill prevention
device. Overfilling vessels may cause a violent rupture, resulting in severe injury or death. Take care to ensure overfilling does not
occur.
•Flammable gas under pressure – liquified petroleum gas (LP-GAS) can cause a fire or explosion if ignited. Keep all heat and ignition
sources away from the hazardous classified area(s). Make sure all pressure gauges read 0 psig before removing any clamps and verify
the system is open to the atmosphere (in case of faulty gauge).
•Avoid breathing LP-GAS vapors. Breathing in vapors may cause heart arrhythmia, loss of consciousness, or even cause suffocation.
Exposure may irritate eyes, nose, throat, and skin. Please read the manufacturer’s Material Safety Data Sheet for further safety
information on LP-GAS and ethanol.
•Operate equipment ONLY in a facility with an approved, functional alarming solvent detector and ventilation/exhaust system sufficient
to maintain the atmosphere below 25% of the solvent’s lower flammability limit (LFL). Solvent vapors are heavier than air and can
settle in low places. When at steady state (when no heating, cooling, or transferring is occurring), monitor pressures for any significant
pressure drops. At steady state, a pressure-drop of 10 psig or greater may indicate a leak. Use a C1D1-rated or C1D2-rated (as
applicable) handheld combustible gas detector less than 48 in off the ground to identify or confirm the presence of a leak.
•Do not make any unauthorized modifications to the equipment. Do not install replacement parts that have not been approved by
Precision® Extraction. Modifications, unapproved components, or improper assembly may result in noncompliance, property damage,
or serious injury/death.
•Wear appropriate personal protective equipment (PPE) including safety glasses and gloves during use. Avoid contacting solvent or
inhaling solvent vapors. Read the solvent manufacturer’s Safety Data Sheet (SDS) for further safety information. Print and retain the
solvent manufacturer’s SDS on site.
•Hoses may contain solvent under pressure. Contact with cold solvent may cause frostbite or other injuries. Use extreme caution and
wear proper PPE when disconnecting any hose.
•Only allow trained personnel to operate or work on the equipment. This applies to all assembly and servicing work.
•Do NOT use or store equipment or containers where they could be exposed to high temperatures. DO NOT heat equipment or
containers above 52°C (125°F).
•Ensure the system is properly grounded to reduce the risk of static build up.
•The facility must provide adequate ventilation/exhaust as determined by the Engineer of Record to maintain the local atmosphere
below 25% of the Lower Flammability Limit (LFL).
•No air is present in the inert gas push.
•Use only approved solvents.
It is the owners’ and operators’ responsibility to read and understand the following safety information. This equipment is to be installed,
operated, maintained, cleaned, and transported only by trained, qualified personnel. Follow these safety precautions to ensure the safety of
persons and property. Failure to read and heed these instructions places operators, facility, and equipment at risk. Improper use could result
in a serious accident. Print this section and display it where it can readily be seen by equipment operator(s).
DANGER: FIRE AND EXPLOSION HAZARD: MISUSE OF THIS EQUIPMENT CAN RESULT IN PROPERTY DAMAGE, SEVERE INJURY, OR DEATH.
NOTE: USE OF THIS EQUIPMENT CONSTITUTES USER AGREEMENT TO UTILIZE EQUIPMENT FOR LAWFUL PURPOSES ONLY. USER ASSUMES
SOLE RESPONSIBILITY FOR SAFE USE, TRANSPORT, AND STORAGE OF EQUIPMENT. USER ASSUMES ALL RISK ASSOCIATED WITH
EQUIPMENT USE.
