• Air piping must be supported independently of the dryer.
• A properly sized Parker pre-filter is recommended ahead of the dryer to maintain
optimal performance and warranty validation. It should be installed as close to the
dryer as possible. Any piping between the pre-filter and inlet of the dryer must be
stainless steel, copper, galvanized, aluminum or other non-corroding material. A
union between the pre-filter and the dryer is recommended for ease of assembly
and change-out of filter element. Please refer to section 10.1 for proper pre-filter
selection.
• Direction of the air flow must be observed for proper installation.
• Install a bypass line and gate valves to permit isolation of the dryer from the air
system. This is done to provide easy service and/or removal of the dryer without
interruption of air to the system.
• Make the connection to the draining system, avoiding connection in a closed circuit
shared by other pressurized discharge lines. Check the correct flow of condensate
discharges. Dispose of all condensate in conformity with current local environment
regulations.
• Set drain time intervals to ensure complete condensate removal from dryer.

Electrical Connections
To be performed by a qualified person only. Risk of serious injury or death. Observe
Lock out/Tag Out Procedure: Disconnect, lock out and tag all power at source prior
to attempting repairs or adjustments to rotating machinery and prior to handling any
ungrounded conductors.
Provide breach and short circuit protection as well as disconnect means per local and
national codes.
Before connecting electrical power to the dryer check for correct voltage at the
connection box. Panel Removal: To remove front or side panels, remove screws and lift
panel up, then pull out the bottom.
All units must be externally grounded to protect against severe electrical shock.
1.
Remove electric box cover from inside unit.
2.
Locate the wires.
3.
Locate hole on side of box, place and tighten connector, run wires through
connector.
4.
Make sure no bare wire is exposed; replace box cover and screw closed.
5.
Line input wiring connections are made to line side on compressor contactor
6.
Should the compressor not start, see start up procedure.
Wire the dryer separately from the air compressor. The dryer must not cycle
with the air compressor.
Crankcase heaters are pre-wired from the factory to the line side of the compressor
contactor. When power is applied to the dryer, the heater will energize. Heater must be
energized for 8 hours prior to start–up and after prolonged shut down. The power must
be left on at all times except when servicing.
