INSTALLATION
.
WARNING: This product is intended for use in industrial compressed air systems only. Do not install where pressures or temperatures can
exceed those listed above.
WARNING: Completely relieve all pressure from the system before attempting to install the drain. Disconnect compressor from all external
sources of pressure and electrical power. Employ approved lockout/tagout devices while working on the system. Failure to follow these
directions can result in serious personal injury and death.
To prevent scale and debris from entering the solenoid valve, the Wye Strainer
(4) must be installed upstream of the unit in the location indicated. Install drain in
proper flow direction as indicated. A field supplied manual shutoff valve (5) may
be installed upstream of the Wye Strainer and Drain Unit to facilitate service.
For best results, the drain should be mounted at a point lower than the tank drain
outlet and all piping should be pitched downhill to drain. In cases where normal
installation is not possible, the drain may be mounted at a point higher than the
(b) the drain cycle is adjusted to account for increased volume.
Connect unit to an approved, properly grounded electrical supply.
Warning: Drain should only be activated when compressor is in operation. When the compressor is shut down, power supply to drain
should be disconnected. Failure to follow these directions will cause the solenoid coil to overheat and fail prematurely.
Rotate the Cycle knob (1) on the front of the unit to a setting from 1 to 60 minutes. This controls the period of time between drain activations. Rotate the
Drain knob (2) to a setting from 1 to 30 seconds. This controls the period of time the drain is open for each cycle. Observe drain operation over time
