O&M Manual v2
Page 8
All personnel involved with installation, operations, and maintenance of the PSA Nitrogen Generator must
follow safe working practices, OSHA, and local health/safety code regulations during the installation,
operation, and maintenance of the unit.
Warning:
This manual must be read in its entirety prior to installing and operating the generator to
prevent accidents and damage to the generator
Contact your supplier if you detect a problem that you cannot solve with this manual.
Only use the generator in accordance with its designed purpose.
Only service-engineers, that are qualified to work on electric and pneumatic equipment, are
allowed to do the installation, maintenance and repairs. Unqualified people are not allowed to
repair the equipment.
Do not tamper or experiment with the equipment or exceed the technical specifications
1.3
Room Ventilation Recommendation
The nitrogen generator will exhaust a slightly higher oxygen (O2) to nitrogen (N2) concentration than
normally found in air. Typically concentration will be between 20.9 to 40% O2 balance with N2. The
volume of gas exhausted to the room is approximately equal to bed’s pressurized volume at 50% of the
incoming air pressure to the generator every minute. For example, let’s assume the bed volume at
atmosphere is 10 cubic feet, and the incoming air pressure is equal to 100 PSIG, then the calculations are
as follows:
100 PSIG x 50% = 50 PSIG, then convert PSIG to PSIA,
50 PSIG +14.7 PSIG = 64.7 PSIA, then convert to ATM,
64.7 PSIA / 14.7 (PSIA/ATM) = 4.4 ATM, then calculate total volume stored,
4.4 ATM x 10 cubic feet/ATM = 44 cubic feet, then consider this once every minute,
44 cubic feet / 1 minutes = 44 standard cubic feet per minute vented from the unit.
1.4
Limits of Liability
Buyer's exclusive remedy for all claims shall be for damages, and seller's total liability for any and all losses
and damages arising out of any cause whatsoever including, without limitation, defects in or defective
performance of the system, (whether such claim be based in contract, negligence, strictly liability, other tort or
otherwise) shall in no event exceed the purchase price of the system in respect of which such cause arises or,
at seller's option, the repair or replacement of such; and in no event shall seller be liable for incidental,
consequential or punitive damages resulting from any such cause.
Seller shall not be liable for, and Buyer assumes all liability for, the suitability and the results of using
Nitrogen by itself or in any manufacturing or other industrial process or procedure, all personal injury and
property damages connected with the possession, operation, maintenance, other use or resale of the System.
Transportation charges for the return of the System shall not be paid unless authorized in advance by Seller.
