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.

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
