Alcatel Vacuum Technology France --- IPUP A100 Instruction manual
Shipping procedure for
contaminated pumps
Before shipping any pumps, remember to blow out the water line,
purge the functional block with N
2
and pressurize with dry nitrogen.
Remaining process gases in the pump may cause severe
injury or death.
Before removing the pump, continue N2 flow from the
process tool for 30 min. (see C 50) page 3/4 for programming
instructions.
Nitrogen pressure and flow rate should be identical to the
programmed values during process.
During pump removal, operator could be in contact with
process residues on the exhaust which could cause severe
injury or death.
Ask your safety department for instructions according to the
local statements.
Procedure for emptying the water
circuit
As the water circuit is equipped with water valve (normaly closed),
emptying operation must be done when the pump is running (so
valves are opened).
Prepare a flexible pipe (A) with a 1/4 inch quick male connector (to be
connected to compressed air circuit) and another flexible pipe (B) with
a 1/4 inch female connector.
Disconnect inlet and outlet water fittings on the pump.
Connect pipe (A) on the pump, at location ”Water Out” and place the
other end of the pipe in a vessel (total water volume will be less than
one litre).
Connect pipe (B) at location of ”Water In” and connect the other end
to a compressed air circuit (2 to 5 bars).
When the water is filled out, quickly stop the pump and disconnect
pipes (A) and (B).
D
This operation must be performed quickly, because without any
water cooling the pump will overheat after a few minutes and will be
in warning/hazard mode.
