Draining the System

Disconnecting the pump will not necessarily drain all other parts of the piping system. If there are any concerns with the proper procedure or necessity
of draining the suction plumbing, contact a water systems professional. All Inline systems, piping, and water tanks exposed to freezing weather should
be drained when appropriate. There is a drain plug on the bottom of the unit that may be used to drain the disabled system. If there are any concerns
with the proper procedure to drain the system's pressure tank, contact the tank manufacturer for assistance.
Cleaning the Flow Switch
In some cases the flow switch may become clogged with mineral deposits or plugged with debris.
In those cases the switch may be cleaned by the following steps:
1. Disconnect the unit from incoming power.
2. The system may be under pressure. As such, close both the inlet and outlet valves and drain
all pressurized water from the system prior to performing maintenance on the flow switch.
3. Remove the (6) control cap screws and remove the cap.
NOTE: Be careful when removing the control cap, as there is an electrical cable attached to the head.
4. Remove the three Phillips screws that hold the flow cap in place.
5. Remove the flow control cap. The O-ring may come off with the cap or may remain in the head.
Remove the O-ring and make sure it is free of debris. Place it back on the bottom of the flow cap.
6. Use a small metal object, such as a screwdriver or nut driver, to retrieve the magnetic flow control piston
from the cavity (it is magnetic and will stick to the metal object).
7. Clean the magnetic flow control piston with a cloth.
8. Clean any debris or residue from the head where the piston is inserted.
9. Replace the Piston into the head. Press the flow cap w/ O-ring firmly into the head. Tighten the (3) screws
to 15 in-lbs torque (do not overtighten).
10. Replace the control cap and tighten (6) screws to 15 in-lbs torque.
11. Re-calibrate control head (see page 14).
Disconnect power to the unit before attempting to perform these maintenance functions.
All maintenance functions should be performed by a qualified service professional.
