3.3 Installation Codes and Procedures
• Safe and efficient operation of the unit depends on proper
installation.
• Authorities with jurisdiction should be consulted before
installing to verify local codes and installation procedures.
In the absence of such codes, install unit according to the
National Electric Code and NFPA No. 70-latest edition.
• A qualified installation and service agent versed in all
regulatory codes must complete installation of this unit.
3.4 Locating and Installing the Dryer
1. Locate unit on a level foundation. Dryer should be mounted
on a suitably structured flat and level floor or base that is
free from vibration.
2. Install unit to provide adequate clearance for maintenance
services. Dryer and accompanying filters should be installed
with at least 2 to 5 feet clearance from the adjoining walls
to provide easy access for routine maintenance and
adequate air flow across the condensing coil.
3. The frame or cabinet must be securely bolted to the
foundation to prevent movement resulting from earth
tremors and induced piping vibration.
4. Install unit using the correct pipe size and pressure rating.
See drawing package provided with the unit. Connect the
inlet of the dryer to the moist gas from the 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 appropriately rated reducers.
5. Optional system configuration: Install a dryer bypass or
isolation valve to allow isolation of the dryer for service and
maintenance without interrupting the compressed air flow.
6. Minimum recommended filtration: Install an Aircel inline
compressed air particulate pre-filter before the dryer to
protect it against dirt and possible clogging of the heat
exchanger.
7. Additional recommended filtration: Install an Aircel inline
compressed air coalescing after filter after the dryer.
8. Provide adequate power supply. See Section A: Specifications.
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. Three phase units are equipped with
a phase monitor, which will prevent unit from operating
when wired in reverse. It is mandatory that the dryer be
grounded. Use of your plant’s frame as a ground may
cause problems with the controls. A fused disconnect is
not supplied with this equipment; therefore, one must be
supplied by customer. All electrical fuses, breakers, etc.
WARNING!
Electric Shock Hazard
This machine is connected to high-voltage power,
which can cause severe electrical shock and injury.
• Follow proper lock out/tag out procedures before
performing service or maintenance work.
• Electrical installation must be performed by a
qualified electrician and comply with all applicable
national and local codes.
WARNING!
Inappropriate tools hazard
Using inappropriate tools for installation or
maintenance work can lead to personal injury or
property damage.
Appropriate tools must be used for all installation and
matinenance work.
WARNING!
Pressure and temperature hazards
Operation at elevated pressure or temperature
may cause damage to the dryer or serious injury to
personnel.
Each dryer is checked at the factory for proper
operation at the conditions noted on the serial plate
label.
