2.5.1 WHM Actuator-Controlled Ball Valve Installation
If the RECON Water Heater was ordered for use with an isolation valve, it will be packed
separately within the shipping container. If installation is required, proceed as follows:
WHM Ball Valve Installation
1. Remove the ball valve from its stowed location within the shipping container.
2. Attached the valve to the cold water inlet (Figure 2.4) of the unit using the pipe union and
nipple provided, or hot water outlet if building recirculation is attached to the unit.
3. Ensure that the valve is positioned with the actuator enclosure position as shown in Figure
2-4.
4. AERCO recommends that another pipe nipple and union be attached to the valve inlet prior
to connecting the hot 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 RECON
harness at the rear of the unit.
7. This completes the actuator-controlled ball valve installation.
