Unpacking and Installation.
Although Peak Scientific take 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.
After unpacking and a visual inspection, the unit should be placed in a ventilated area away from direct
sunlight. Care should be taken not to obstruct the ventilation holes on the sides of the unit not the fan
outlet to the rear. The generator will be warm to touch and will give off heat.
The generator should be placed on a steady and level base. It is designed to fit under most workbenches
alternatively it may be placed on a bench or in any convenient location.
Performance of the generator (like all sophisticated equipment) is affected by ambient temperatures and
humidity. 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.
Operation in relative humidity exceeding 70% may overload the filtration system and result in moisture
carry-over. Additional moisture traps should be installed downstream of the generator should ambient
regularly exceed 70% Rh. and also if the generator is any distance from the application. Moisture traps or
coalescers should be located as close to the application as possible. 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.
