Chapter Five: Servicing the System
NOTE: Be sure to contact Aclarus or your local support technician for assistance.
Servicing the Aclarus Water System properly is a key component to its performance
and longevity. Please follow the instructions carefully.
Draining the System
Certain maintenance activities may require the Aclarus system to be emptied of water
first. Prior to exposure to cold below freezing, system must be fully drained. To drain
the Aclarus system properly, follow these steps in sequence:
1. Turn the Aclarus Ozone Water System off.
2. Shut off the incoming water flow by turning off the power to the main pump or by
closing
the system’s shut-off valve.
3. Relieve pressure on the system by opening a tap located after the Aclarus Ozone
System.
4. Place container under unions in AWOT-4 and open unions at the front and back of
system. Expect approximately 15-20L or water to be drained.
5. Slowly open the discharge valve at the discharge of the tank and ensure that the
water volume in the gas-off chamber disappears (if applicable).
6. Allow the system to drain fully. The two bolts on the pump face can be removed for
additional drainage of water from the pump.
NOTE: When refilling the system after completion of repairs or maintenance,
ensure that the valve controlling the incoming water flow is opened only half-way
as the system refills. Opening the valve rapidly may cause the water lines to
hammer. When system is full, open supply water valve fully to ensure system is
not starved of water during normal operations.
Testing and Replacing the Flow Switch
The flow switch in the system activate the Aclarus Ozone Water System when there is
water flow through the pipes. Occasionally, particulates may impede the activation or
deactivation of the paddle in the flow switch, or a mechanical failure may cause the
switch to operate improperly. If either of these conditions occurs, the system may
begin stopping or starting incorrectly.
