3.1 MAINTENANCE

The HydroTech pump's reservoir water should be changed at least once a month or if frequent use of the

performance and reduces foaming. To change the water, follow the steps in Table 5.
Step Procedure
1. Turn off the Vacuum pump.
2. Connect drain line to the
Reservoir Drain Port.
3. Place drain line into a large
bucket or sink.
4. Turn on the pump.
5. Turn off the Pump.
6. Refill the reservoir with water.
Table 5.
