GENERAL SAFETY INFORMATION
When properly installed and operated, the purifier is designed
to purify ordinary compressed air to acceptable levels for
supplied air breathing systems. Appropriate safety precautions
must be observed to assure satisfactory service.
Consult factory for assistance and recommendation if purifier
performance does not meet design specifications or when its
intended application is questionable.
1. LIMITATIONS ON USE OF SUPPLIED AIR RESPIRATORS
This equipment is for use with supplied air respirators.
Supplied air respirators should not be used in a hostile
environment (highly toxic or oxygen-deficient) which
is immediately dangerous to life, or where the user
cannot escape without the aid of a respirator. Self-
contained breathing apparatus should be used for these
applications.
2. COMPRESSOR INTAKE
This equipment is for use with ordinary compressed air.
The compressor intake should be located to insure that
the air supply source is not oxygen-deficient or subject to
unusual or gross contamination.
3. CARBON MONOXIDE DETECTION
This equipment is equipped with a humidity indicator
which gives advance warning of the impending expiration
of the catalyst used to eliminate carbon monoxide. This
indicator is not a carbon monoxide detecting device. A
compressor high temperature alarm or carbon monoxide
alarm (or both) should be provided. If a compressor high
temperature alarm only is used, frequent testing for
carbon monoxide concentration should be conducted.
4. LIMIT TO CARBON MONOXIDE REMOVAL
This equipment is provided with a catalyst which can
convert carbon monoxide to carbon dioxide. Its capacity
to decrease the concentration of carbon monoxide is
dependent on the air flow rate and inlet concentration
of carbon monoxide. Although this catalyst is capable of
eliminating very high concentrations of carbon monoxide
(especially if of short term duration), carbon monoxide
inlet concentrations higher than 400 PPM v/v exceeds
the intended design specifications. Conversion of
concentrations higher than 400 PPM v/v will result in the
formation of excessive levels of carbon dioxide, and will
also cause an undesirably high air temperature rise.
5. PRESSURIZED DEVICES
This equipment is a pressure contain-
ing device. Observe normal precautions
when operating and servicing. Do not
exceed design limitations of pressure
and temperature as noted on unit serial number tag.
Always depressurize before servicing.
6. MAXIMUM WORKING PRESSURE
Do not exceed maximum compressed air pressure rating
as listed on dryer serial number tag.
