Installation Checklist - Aircel AHLD E-Series Installation And Operation Manual

Installation
Only qualified personnel should make electrical and mechanical connections.
Equipment for Installation: This dryer does not need any special tools for installation
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 Regulator: 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 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: If the event that mufflers have been shipped loose, they must be installed and secured
By-pass: If the dryer is not supplied with optional by-pass valve it is highly recommended that by-pass
valve be installed around the dryer and filters. These by-pass shut-off valves will permit the dryer and
filters to be removed from the compressed air system for servicing without shutting down the entire
compressed air system.
Electrical: Make all electrical connections to the dryer as shown on the wiring diagram. Special care must
be taken in connecting the proper voltage as indicated on the specification sheet and wiring schematic.
Additional Valving/Piping: When installing equipment or components keep in mind the serviceability of
the equipment and provide additional valves to isolate, bypass, and to depressurize as needed.
Exhaust: If you intend to vent your exhaust with additional piping, the discharge piping from the exhaust
should not be piped upward without an arrangement for removing trapped condensate. Make sure that
you do not apply a backpressure on this exhaust system. If exhaust piping is to be extended, try to stay
within 15 to 20 feet and use the next larger pipe size.
Note: It is mandatory that dryer be grounded. Use of your plants frame as a ground may cause problems
with the control. A fused disconnect is not supplied with this equipment therefore one must be supplied
by customer. All electrical fuses, breakers, etc. should be properly sized.
Aircel is not liable for any code violations; component damage, downtime or consequential damage related
to customer supplied electrical components and connections.
