!WARNING!
Failure to follow these instructions or to properly install and maintain this
equipment could result in an explosion and/or fire causing property
damage, personal injury or death.
MEC equipment must be installed, operated, and maintained in
accordance with federal, state, local codes and manufacturer's
instructions. The installation in most states must also comply with NFPA
No. 58, and ANSI/CGA G-2.1.
For installation in the European Union, the equipment must also comply
with PED/TPED and EN ISO standards. Periodic inspections, intermediate
inspections and exceptional checks of transportable pressure equipment
should be carried out in accordance with the Annexes of Directive
2008/68/EC and with 2010/35/EU Directive (TPED) to ensure continued
compliance with their safety requirements.
Only personnel trained in the proper procedures, codes, standards, and

WARNING: These products contain a chemical known to the
State of California to cause cancer and birth defects or other
reproductive harm.
Installation
!CAUTION!
Make sure all pressure is released from upstream piping before
proceeding with installation.
1.
Apply Loctite #565 or suitable thread sealing compound to
male NPT threads of mating fitting or hose end connector.
2.
Tighten connection by placing a suitable wrench on the
wrench hex of the ME806-16 Turbo-Flo LE Transfer Valve. If
the hose end connector does not include a swivel, continue
tightening the valve onto the pipe or fitting until the valve is
upright (operating lever facing upward) when installed in final
position.
3.
Connect a pressure source of a least 150 psi (1034 kPa) and
check for leaks (as evidenced by bubbles) at all joints and
sealing surfaces, using a suitable leak detector solution at all
joints. Ensure all connection joints are free of leaks before
putting the ME806 LE valve into service.
Operation
!WARNING!
To avoid risk of serious injury or death, never attempt to open the
ME806 Valve when it is under pressure and not properly connected to
transfer system. The ME806 Transfer valve is equipped with a pilot
equalization feature that will discharge a small amount of product if
attempting to open when not properly connected to a transfer
system.
1.
Connect the Valve – With pump off, connect the ME806 TURBO-
FLO LE Transfer Valve to an ME868 TURBO-FLO ACME Adapter,
ME807/ME808 TURBO-FLO LE Shut-off valve or other shut-off
valve with standard 3-1/4" female ACME connector; tighten with
appropriate wrench.
2.
Open the Valve(s)
a.
Ensure the pump is off and the connected Shut-Off valve or
other connection is closed; open the ME806 Transfer valve by
releasing the locking latch and moving the handle toward the
ACME connection.
*Note: A slight motion of the handle opens a pilot orifice that
equalizes pressure on both sides of the valve. Once equalized,
the valve will open fully with continued pressure on the
handle. Once opened, the valve will remain open until the
handle is moved to the closed position (away from the ACME
connection). If the valve does not open fully with reasonable
pressure on the handle, check to make sure the latch is pulled
all the way out of the locking notches in the valve casting and
that the hose-end valve is fully closed.
b.
Open the connected inlet shut-off valve or other connection.
3.
Transfer Product – Turn pump on and follow safe filling / transfer
practices as outlined in the NFPA 58, national fuel gas code.
*Note: In case of emergency, the ME806 valve can be closed
instantly by snapping the spring loaded handle to the closed
position (away from the ACME connection).
