Cleaning the Check Valve And Check Valve Screen
This procedure applies to furnace installations with inside and outside tanks. The following protective
gear should be worn when cleaning the check valve/screen:
• Rubber gloves
• Safety goggles
1. Refer to Figure 9D. Remove the one-piece suction oil line from the tank.
2. Remove the check valve and screen. Clean these components in a parts washer.
3. Check the operation of the check valve. The valve must seat so it is airtight to hold pump prime.
4. Re-assemble and re-install the components. Apply Permatex #2 non-hardening gasket sealer or
equivalent to the threaded fittings. Firmly tighten all connections so the suction line is 100%
airtight.
5. Follow pump priming instructions in Section 5 to re-establish prime.
