1. Safety information
Your attention is drawn to Safety Information Leaflet IM-GCM-10, and, in the UK to
IEE Regulations (BS 7671). Elsewhere, other regulations will normally apply.
2. Description
The WAV1 solenoid is designed for use with the BBV980A bottom blowdown valve. The valve
is a 3-port solenoid valve for use with air or water up to 90°C. The valve has a brass body and
corrosion resistant internals. Application of the rated voltage to the coil will allow air or water into
the BBV980A actuator. When de-energised the solenoid will vent the compressed air or water
in the actuator to atmosphere or drain.

6. Installation
The WAV1 is rated for operation in ambient temperatures from -5oC to +50oC. Solenoid
protectionratingisIP65.Outdoorinstallationwithoutadditionalenvironmentalprotectionisnot
recommended.
To fit a WAV1 type solenoid assembly to the valve actuator:
-Separate the supplied split coupling provided with the WAV1.
-Screw one half of the coupling into the G¼" BSP connection on the underside of the BBV980A
actuator and tighten using a 6 mm A/F allen key.
-Connect the other half to port 'A' on the WAV1 and tighten.
-Fit the two halves of the coupling together and tighten using a 19 mm A/F spanner.
-Connect the air or water supply to port 'P' (¼" BSP). If water is the operating medium connect
the discharge port (port R) to a safe drain point.
The solenoid valve incorporates a lockable manual override which can be operated by
pushing the spring loaded plastic button inwards and turning it clockwise to lock it in the
'override' position. This bypasses the solenoid and allows the BBV980A to be operated
without an electricity supply. The screw is released by turning it anticlockwise.
The WAV1 can also be mounted remote from the actuator.
7. Wiring
Caution: Do not apply power to the coil unless it is fitted to the valve.
The rated voltage is printed on the name-plate. The cable socket may be moved through 360°
by removing the central plastic screw and turning the connector. Ensure the cable socket gasket
is slightly compressed on refitting.
