AERCO requires use of WHM sequencing valves in a multi-unit tankless
If installation is required, proceed as follows:
1. Remove the ball valve from its stowed location within the shipping container.
2. Attached the valve to the cold water inlet of the unit using the pipe union and nipple
provided.
3. Ensure that the valve is positioned with the actuator enclosure position as shown in Figure
2-3b.
4. AERCO recommends that another pipe nipple and union be attached to the valve inlet
prior to connecting the cold water supply piping.
5. Tighten all pipe connections after the valve is properly positioned.
6. Connect the 4-pin Molex connector on the valve to the mating connector on the Innovation
harness at the rear of the unit.
7. This completes the actuator-controlled ball valve installation.
