Visually inspect the drain valve assembly for serviceability and check that the transparent bowl is clean.
Dismantle, clean and replace as necessary in accordance with "Drain valve assembly" described below.
4. Flexible pipework (where fitted):
Examine all flexible pipework in the plant room for signs of stress or damage and check for earth continuity.
5. System performance:
With the AGS disposal system activated, and using the test equipment inserted in only one terminal unit
at a time, check that with a 1 kPa pressure drop the flow rate does not exceed a maximum of 130 litres/
min.
Adjust the pressure drop to 4 kPa and check that the flow rate exceeds a minimum of 80 litres/min.
Annual inspection
The annual inspection consists of the following operations:
1. Exhauster unit:
Remove exhauster unit inlet and outlet filters in accordance with above section Quarterly inspection,
Exhauster unit . Clean the mesh disc and replace filters as necessary.
2. Flow regulating valve:
• Clean the mesh disk
• Grease the shaft with Klubersynth UH1-151
If the flow regulating valve is equipped with an air filter (optional), replace the air filter element.
3. System performance:
With the disposal system activated, and using the test equipment inserted in only one terminal unit at a
time, insert a test probe and check that with a 1 kPa pressure drop the flow rate does not exceed a maximum
of 130 litres/min. Adjust the pressure drop to a 4 kPa and check that the flow rate exceeds a minimum of
80 litres/min.
Drain valve assembly
The procedure to dismantle, clean, inspect and assemble the drain valve assembly is as follows:
1. Drain the assembly and release the pressure
Close the valve above the drain assembly to isolate it from the disposal system.
2. Unscrew the transparent bowl from the lid and clean it.
Use only soapy water to clean the transparent bowl. Solvents will cause damage.
3. Refit the drain assembly.
Assemble transparent bowl and lid. Tighten assembly and turn on drain isolation valve.
Flow regulating valve
The air inlet to the flow regulating valve must not be obstructed or the system integrity and
performance will seriously be affected.
