WARNING
DO NOT REMOVE THE HATCH COVER UNTIL ALL AIR
PRESSURE IS OUT OF THE VESSEL. PUSH ON THE HATCH
COVER BY HAND TO FIND OUT IF THE VESSEL PRESSURE IS
REDUCED TO ZERO.
DO NOT TRY TO TIGHTEN THE HATCH COVER IF YOU HEAR
OR FEEL A LEAK. IMMEDIATELY SHUT OFF THE AIR OR GAS
SUPPLY TO THE VESSEL AND REDUCE THE DRYER
PRESSURE TO ZERO.
ALWAYS INSTALL A NEW GASKET EVERY TIME THE HATCH
COVER IS REMOVED, OR AT LEAST ONCE PER YEAR.
REPLACE THE HATCH COVER EVERY FIVE YEARS
REGARDLESS OF CONDITION. USE VAN AIR AUTHORIZED
PARTS ONLY.
DO NOT USE POWER TOOLS OR CHEATER BARS TO
TIGHTEN THE NUT ON THE COVER. TOO MUCH FORCE CAN
DISTORT THE COVER AND/OR THE GASKET. IF DAMAGED
BY OVERTIGHTENING, THE COVER CAN BLOW OUT AND
CAUSE SERIOUS INJURY. (Note: Tighten the nut until it is
snug only. When pressure is in the vessel, the seal will be
complete.)
INSPECT THE COVER AND SEALING SURFACE EVERY TIME
THE COVER IS REMOVED, OR AT LEAST ONCE PER YEAR,
FOR DAMAGE SUCH AS CORROSION, CRACKS, OR
DISTORTION. IF THERE IS ANY DAMAGE, INSTALL A NEW
COVER AND GASKET. USE VAN AIR AUTHORIZED PARTS
ONLY.
DO NOT REMOVE, REPAIR, OR REPLACE ANY ITEM ON THE
DRYER WHILE IT IS UNDER PRESSURE. DEPRESSURIZE THE
DRYER COMPLETELY BEFORE STARTING INSTALLATION AND/
OR MAINTENANCE PROCEDURES. SERIOUS PERSONAL
INJURY MAY RESULT IF THESE SAFETY RULES ARE NOT
FOLLOWED.
DO NOT OPERATE THIS PRESSURE VESSEL ABOVE MAXIMUM
WORKING PRESSURE (MWP) AT MAXIMUM OPERATING
TEMPERATURE (
O
F) AS SHOWN ON THE ASME DATA PLATE.
THIS ASME CODE VESSEL MUST BE PROTECTED BY A
PRESSURE RELIEF VALVE. Refer to OSHA 1910.169 Par. b,
Sub. Par (3) and ASME Boiler and Pressure Vessel Code,
Section VIII, Division 1, UG-125 through UG-136. Also check
government regulations, i.e., state and local codes.
DO NOT WELD, GRIND, OR SAND VESSEL, OR IT WILL NOT
BE SAFE TO OPERATE. (Note: Any alteration to the vessel
will void the ASME Code Certification and the warranty.)
ANY DAMAGE TO THE VESSEL CAN MAKE IT UNSAFE.
INSPECT OUTSIDE AND INSIDE OF VESSELS REGULARLY
FOR BULGES, CORROSION, DENTS, GOUGES, LEAKS OR
SIGNS OF FIRE. IF DAMAGED, TAKE OUT OF SERVICE
IMMEDIATELY AND NOTIFY YOUR CERTIFYING AUTHORITY.
USE THE PROPER SAFETY RULES FOR THE GAS BEING
PROCESSED.
