tank’s drain hole and prevents any large debris from entering the pump.

WARNING HOT SURFACE
The ASU will still be hot during this procedure. Use insulated gloves and
protective clothing when handling the tank filter.
3. Use a hook or a pair of pliers to pull the tank filter out.
4. Emerse the clogged filter in flushing fluid (PN L15653), then use a hot air gun and rags to clean
it.
5. Remove any accumulation of debris from the floor of the tank before re-installing tank filter.
6. Re-insert the filter into the tank.
7. Refill the tank and resume production.
