3. Installation & Wiring
■
Receiving & inspection
Carefully inspect the packaging and dryer for external and internal damage. If you suspect
damage has occurred during shipment, notify the transportation agency at once. This is the
customer's responsibility.
Check the name plate for correct power supply requirements.
Inspect all piping and tubing. Vibration during shipment may have loosened the connections.
Desiccant air dryers are tested and operated before leaving the factory. They are ready to
operate after connecting to proper services.
■
Location
Locate your Desiccant Air Dryer on a level floor free from vibrations and in clean surroundings.
Although the dryer is a free standing package, it may be secured by bolting the dryer base to the
floor. Allow approximately three feet on each side of the dryer for ease of connecting and
maintaining the dryer.
The ambient temperature in the dryer's location should range from 2
℃
to 40
℃
. The dryer will
function in warmer ambient, but as a result, the degree of dew point suppression will decrease.
Operation of the dryer in ambient approaching freezing could cause freezing of separated liquids
in the pre-filter sump or in the dryer itself. For dryer operation at temperatures below freezing,
Pioneer recommends heat tracing the pre-filter sump, drain trap and inlet manifold. For more
information on heat tracing, contact your distributor or the factory.
Protective barriers are recommended for the prevention of accidental damage that may occur
due to vehicular or personnel traffic, particularly for dryers located in open areas.

Connecting service
1. Connect inlet piping, including a shut off valve.
2. Connect outlet piping, including a shut off valve.
3. Install pre-filter(s) and after(s) if not factory installed.
4. If desired, install bypass piping using bubble tight valves.
- Bypass piping is recommended for ease of maintenance, troubleshooting and service.
5. Connect electrical supply to the control box. This should be performed by a qualified
electrician according to local and national codes. (See Appendix Control Panel)
6. Install access ports upstream and down-stream of the dryer for dew point and temperature.

Caution!
Must install a suitable earth leakage circuit breaker.
