MAINTENANCE
Maintaining the Pressure Gauge
The pressure gauge is the primary indicator of how the system is operating, so correct functioning is critical.
Replace the pressure gauge (Pentair P/N 190058) if it does not meet the requirements below:
1. Pressure gauge should go to zero (0) when the system is turned off and pressure is relieved.
2. Pressure gauge should indicate pressure when the system is operating.
3. The pressure gauge should be readable and not damaged in anyway
Cleaning the Manual Air Relief Valve
RECOMMENDED EQUIPMENT:
• 5/16" Drill Bit (to check air passage)
• Silicone-based Lubricant (if needed)
PROCEDURE:
1. Shut off pump and relieve pressure.
a. Turn the pump OFF and shut OFF any automatic controls (e.g., timers)
and disconnect power to ensure that the system is not inadvertently
started during maintenance.
b. Open the manual air relief valve by turning the valve cover assembly a
quarter turn counter-clockwise until it snaps into the full open position.
c. Stand clear of the filter and wait until all pressure is relieved.
Pressure
gauge must read zero (0 psi)
.
2. With the relief valve attached to the Posi-Clear™ RP Cartridge Filter tank,
pull out the locking tabs and unlock the valve stem and cover assembly from
the valve body with a counter-clockwise turn, see
Figure 3
.
3. Pull the valve stem and cover assembly straight up and away from the valve
body.
4. Clean and check the valve stem and body:
a. Clean off any debris.
b. Verify that the filter tank's air passage is open by inserting a 5/16"
drill bit through the valve body.
c. Verify that the valve stem O-rings are in good condition, properly positioned, and lubricated with a
silicone-base lubricant.
5. Reinstall the valve stem and cover assembly with a downward and clockwise motion until it snaps into
position.
Figure 3
If needed, use only a PTFE or silicone-base lubricant on the O-rings. Use of petroleum based
products on O-rings will damage the equipment.
