Shimadzu AA-7000 Series - Installation Guidelines; Recommended Piping System; Environmental and Gas Requirements

27
Make sure all required equipment is available before starting instrument installation. See the installation guidelines for details.
*1 Atomic absorption spectrophotometer stand recommended
*2 Maintain a free maintenance space of 150 to 200 mm to the sides and rear of the instrument.
*3 Do not use pipes containing copper, silver, gold, mercury (or alloys containing these metals) as
pipes for acetylene.
*4 If tap-water equipment is used, ensure that it meets the specifications below.
Faucet 13 or 12 to 15 mm O.D. rimmed faucet
*5 If the supply pressure exceeds 0.17 MPa, use the optional Regulator ASSY.
