SECTION 1 SAFETY

WARNING

DO NOT REMOVE, REPAIR, OR REPLACE ANY ITEM ON THE
VESSEL WHILE IT IS UNDER PRESSURE. DEPRESSURIZE THE
VESSEL COMPLETELY BEFORE ANY 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 (OF) 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.

SECTION 2 HANDLING

2.1 HANDLING INSTRUCTIONS

If the unit is to be lifted by an overhead device, attach the lifting
chains or cables to the vessel lifting lugs on the top head.

must be free of standing water and mud. If the location is outdoors,
a paved surface is recommended.

Models VME-5000 through VME-10000 are shipped without the
elements installed. These elements are shipped separately in

wooden crates. Use extreme caution when unloading or moving the
elements with fork lifts. Always lift the crate from below the crate
supports to prevent the element from being pierced or torn.

2.2 STORAGE INSTRUCTIONS

If the unit is to be placed in storage before it is installed, the location
should be a clean, dry place. The ideal place to store the unit is
indoors. The location should be free from corrosive gasses and
extreme humidity. These conditions will cause damage to the unit.
The unit should be covered with a tarpaulin to keep the it clean.

If the unit is to be stored outdoors, it MUST BE covered completely
to prevent rain or snow from accumulating on the unit. The location

When storing the elements, they should be protected to prevent
them from being contaminated or saturated with water. Provisions
must be taken to prevent vermin from entering the elements and
using the element fibers for nesting material.

The large crated elements should be stored horizontally. Do not
stack them more than 4 crates high.

2.3 EQUIPMENT CHECK

Inspect the vessel and any elements for any damage that may have
occurred during shipment. Check the packing list to insure that all
items shipped with the unit are present.

IF EQUIPMENT HAS BEEN DAMAGED DURING SHIPMENT:

(1) NOTIFY CARRIER IMMEDIATELY.
(2) DO NOT OPERATE BEFORE CONSULTING FACTORY.
