The Bluetooth unit comes pre-wired with an approximately 1.4 Mt sender lead.  Sender leads cannot be cut and joined, doing so will void warranty. Extension leads are available for the three pin plugs.

Extension leads should only be required if you are having communication problems e.g. inside a metal box.
The thread specifications of the sender unit are 1/2" BSP male.   Make sure the sender is fitted with the water flow in the direction of the arrow.  For best results sender should be fitted to a straight section 200 mm from pump & any 90 Deg. elbows.  

You will need to purchase two 1/2" BSP female connectors to the size hose you have, usually 1/2" or 3/4" and two clamps. “John Guest quick connectors” have fittings to suit their hose and the 1/2" BSP sender unit. The H2F-BT12 can be fitted in any convenient location, inside a cupboard, etc. there is no need to have it visible.

​Power:
Open the battery compartment and install two AA batteries.  The buzzer will sound and the Blue light turns
on for three seconds.

Connection to 12 Volt DC: (H2F-BT12V Sold Separately) 
If you have purchased the 12v PCB adapter remove the battery holder and the screw from the battery compartment, then plug the adapter into the two pin plug coming from the battery compartment.  Connect the black wire to the negative terminal and the red wire to a fused (0.5 or 1 Amp) positive power source.  All settings and amounts will be memorised if power is disconnected. 

Note: Due to continuous product improvement, specifications are subject to change without notice.
