Installation Procedure
Only Qualified personnel should make electrical and mechanical connections.
Foundation:
Dryer should be mounted on a suitably structured flat and level floor
or base that is free from vibration. Special care must be used when
lifting the dryer to prevent tip-over
Mounting:
Bolt dryer to the foundation using the boltholes provided in the frame.
Piping:
Connect the inlet of the dryer to the moist gas from the
compressor/receiver/inlet filter. Install the inlet piping and the inlet
shutoff valve. Install the Outlet piping and the outlet shutoff valve (a
union with a valve by-pass can be installed at the inlet and outlet
valves to accommodate isolation of the dryer for maintenance).
Compressed air piping has to be at least the same size as that of the inlet
and outlet connections of the dryer. Larger pipe sizes can be used with
reducers.
Back Pressure regulators:
Install backpressure regulator to prevent any possibility of fluidization of the
desiccant bed. When there is a sudden increase in the demand for
compressed air downstream of the dryer, a huge pressure drop develops and
can affect the performance of the life of the dryer and the drying material
(desiccant).
Desiccant:
Make sure that the dryer towers are filled with desiccant. Larger dryers may
have desiccant shipped separately
– in which case, the media has to be filled
into the pressure vessels from the desiccant fill ports. Care must be taken
when filling the media and it must be done gradually to prevent powdering.
Muffler:
In the event that mufflers have been shipped loose, they must be installed
and secured
By-pass:
If the dryer is not supplied with optional block and by-pass valve system it is
highly recommended that a block and by-pass valve system be installed
around the dryer and filters. This block and by-pass valve system will permit
the dryer and filters to be removed from the compressed air system for
servicing without shutting down the entire compressed air system. Ensure that
the bypass valves are rated for more than 250 Deg. F.
