Optional Valve Actuators

Like the OmniLogic, optional actuators can be used with the HLEXPAND. Note that the internal cams in the actuator may also have to be adjusted depending on
the way the actuator is mounted on the valve and the desired valve action.
Optional TurboCell
The TurboCell must be plumbed AFTER the filter and heater. If installed on a pool/spa combination system, the cell must be plumbed BEFORE the pool/spa return
valve in order to allow proper chlorination of both the pool and the spa. Refer to plumbing diagram below:

before Cell
The cell may be mounted vertically or horizontally, and water can move in either direction through the cell. Install using the 2" unions provided. Tighten unions
BY HAND for a watertight seal. For systems with 1½" plumbing use adapters (provided by installer).
Flow Switch (supplied with P-KIT)
A Hayward flow switch is required if using the optional TurboCell for chlorination, a liquid chlorine dispenser, chlorine tablet feeder or an AQL-CHEM2 for pH dis-
pensing. The flow switch is a safety device that ensures that water is flowing before the OmniLogic/HLEXPAND starts to generate/dispense chlorine or dispenses
acid. It must be plumbed in the same section of piping as the TurboCell or dispenser. Failure to properly install the flow switch can result in explosive gases or
harsh chemicals accumulating in the pool plumbing system.
IMPORTANT: There must be at least a 12" (30cm) straight pipe run before (upstream) the flow switch. If the switch is plumbed after the cell, the cell can be
counted as the 12" (30cm) of straight pipe.
IMPORTANT: To ensure proper operation, verify that the arrow on the flow switch points in the direction of water flow.
