Installation
When the booster pump is in operation, the oil level will fluctuate due to the pumping action of the gears and slinger.
If you cannot see an oil level because the sight-glass is dirty, remove the sight-glass (when you change the oil) and
clean the viewing surface.
Each time you remove a filler plug or drain plug, inspect the plug 'O' ring for cuts or damage, and replace it as
necessary. The plug 'O' rings need to provide a vacuum seal for correct pump operation.
3.9.2 Perfluoropolyether (PFPE) oil
Before you operate the booster pump, ensure that the oil levels are correct (See Table 15). Add oxygen service (PFPE)
oil into the reservoirs as necessary, as described in Section 3.9.1. Each oil-level should be at the centre position of
the oil-level sight-glass.
Oxygen service equipment requires the use of PFPE oil. You must only use Fomblin® Y-25/6 oil. Do not use another
type of oil, or mix oil types when you add oil.
We recommend that you return oxygen service booster pumps to a Edwards Service Centre if major repairs are
needed. Minor repairs can be made in the field. Because of the possibility of a dangerous reaction to dirt and chemical
compositions in an oxygen rich environment, absolute cleanliness of parts, tools, wipers and technician hands and
clothes is required.
WARNING
Only use the type of PFPE oil specified below. If you use another type of oil, this can result in an
explosion.
