Unpacking and Installation
Although Peak Scientific takes every precaution with safe transit and packaging, it is advisable to fully
inspect the unit for any sign of transit damage.
ANY DAMAGE SHOULD BE REPORTED IMMEDIATELY TO THE CARRIER AND
PEAK SCIENTIFIC OR THE DISTRIBUTOR FROM WHERE THE UNIT WAS
PURCHASED.
Note: -
Included with the generator is a pack containing manuals & fittings. Be careful
not to discard these with the packing.
Please save the product packaging for storage or future shipment of the
generator.

Location
The generator in designed to be installed adjacent to the Mass Spectrometer it is supplying. If this is not
convenient then the generator can be sited elsewhere however consideration should be made to the
lengths of pipe runs as pressure drops can result from extended runs of pipe.
The generator can fit under most workbenches although it has been designed to be wall mounted using
the slotted holes to the rear. These are on 100mm centres.
Performance of the generator (like all sophisticated equipment) is affected by ambient conditions.
Continuous operation in ambient temperatures exceeding 25
°
C will lead to a reduction in capacity and
prolonged operation in temperatures exceeding 30
°
C will shorten the life of the unit. Note should also be
taken of the proximity of Air Conditioning outlets. These can sometimes give rise to “pockets” of air with
high relative humidity. Operation of the generator within such a pocket could adversely affect its
performance. Consideration should also be given to the air flow around the unit. It is recommended that
an air gap of 75mm (3”) should be maintained down both sides and across the top of the unit.
