Step 7: Connecting electrical and supply tubing

WARNING: The MG-2/BIR3 must be connected to the 6 VDC battery. Connection to 110

VAC may cause personal injury and/or damage to electronics. Connection of leads other than shown may cause permanent sensor damage.

CAUTION: To avoid activating the sprayhead valve, make sure to connect the sensor cable plugs to the circuit board before inserting the batteries into the battery holder. If the cable is connected or disconnected while the batteries are installed, the station will activate and continue running for 75 seconds.

1.Snap the sensor plugs from the sprayhead into the proper valve’s circuit board.

2.Insert the batteries into the battery holders (see Figure 7a). Mount the battery holders (with batteries) in a convenient location on the frame using the hook-and-loop fastener provided.

3.Snap the battery holder plugs into the female circuit board plugs.

4.Insert the two sprayhead supply tubes

into the two solenoid tube connectors by	Figure 7a

nut by hand (see Figure 7b).

5.Align the valve bracket mounting screws

with slots on the frame. Let the valve bracket slide down to lock into place.

6.Turn on the water supply to the MG-2/BIR3 and check for leaks. Pass your hand in front of each station’s sensor until all the air is purged from the lines and water is flowing smoothly.

IMPORTANT: The Vernatherm™ valve is NOT factory-preset. Upon installation, the valve temperature must be checked and adjusted to ensure delivery of safe water temperature. Water in excess of 110°F (43°C) may cause scalding.

7.Check the temperature when approximately1.0 GPM water flow is reached and adjust if necessary (the range of the

valve is 95°F–115°F	GREEN SUPPLY		RED
(35°C–43°C). To adjust the	TUBE		SUPPLY
