Taylor-Wharton EF-450 - Manual (Page 15)

OPERATION
These instructions are for operators experienced with cryogenic equipment. Before operating the system,
become familiar with the safety precautions in this manual and in reference publications. Study this manual
and the general arrangement drawing located in the back of this manual thoroughly. Know the location and
function of all system components.
Receiving Inspection
Freight and damage claims are the customer’s responsibility. Take time to visually inspect each shipment
in the presence of the carrier’s agent before accepting delivery. If any damage is observed, make an
appropriate notation on the freight bill. Ask the driver to sign the notation before receiving the equipment.
Do not accept equipment with damage that may affect serviceability.
Handling
The Express Fill 450 should be handled only by a forklift or crane. Ensure that handling equipment has
adequate rated capacity for the system weight listed on the general arrangement drawing in the appendix. The
Express Fill 450 is a rugged product intended for years of industrial use. However, take care when
moving the unit. Abuse (dropping or careless handling by forklift) may affect the integrity of the
insulation system or damage piping. Always transport, operate, and store the unit in the vertical position.
Never place the unit on its side.
Important: When lifting by crane, use the lift-eyes provided on the top of the jacket. Never lift the unit
overhead.
Customer Installed Equipment/Piping
When installing the Express Fill 450 for remote filling, be sure to follow accepted design practices for
cryogenic equipment. All equipment must be cleaned for oxygen service. Be sure to include pressure relief
valves in all piping where liquid product could be trapped between closed valves, regulators, etc.
Designing safe and effective cryogenic systems requires extensive knowledge and experience. Persons
lacking the necessary skills are urged to seek competent advice before attempting to design cryogenic systems.
Design and consultation services are available from the factory at the location shown at the front of the
manual.
Filling by Pressure Transfer
Filling by pressure transfer is accomplished by lowering the pressure in the Express Fill 450 below that of the
source vessel. Typically the source vessel is a cryogenic bulk tank or truck mounted vessel. The pressure is
reduced in the Express Fill 450 by venting gas through the vent valve (V-2). Liquid is pushed by pressure
from the bulk tank and into the Express Fill 450.
CAUTION: Follow the safety precautions at the beginning of this manual. Accidental contact with liquid or
cold gas can occur during filling.
A cryogenic transfer hose equipped with a relief valve and dump valve should be used to connect the Express
Fill 450 to the liquid source. Follow the instructions below to fill by pressure transfer:

Visually inspect the Express Fill 450, transfer hose, and bulk tank piping. Do not attempt to fill
the unit if any components are broken or missing.
