6. MAINTENANCE
Important!
- To maintain the dosing pump in good condition, it is advisable to operate the
pump with suction of clean water after each use.
- Regular yearly maintenance will help extend the lifespan of your MixRite dosing
pump. In addition, kit seals need to be replaced every year.
- Regularly clean the water filter at the pump inlet and the fertilizer suction filter.
- If the pump is planned to be out of use for a long period of time, operate the
pump for a few minutes with the suction tube immersed in a tank with clean
water to remove fertilizer residues from the pump, preventing them solidifying in
the pump.
- If there is a fear of frost, and the temperature falling below 4°C (39ºF), empty
the water from the pump. To do this, close the entry and exit valves securely.
Open and dismantle record nut that connects the suction pipe. Press the
backflow prevention valve using a finger or a thin rod, allowing all the water that
has collected in the pump to drain out while pressing the air-release valve at the
top of the pump.
- It is advisable to carry out the maintenance of the pump body whenever soluble
products are used. To carry out the maintenance, remove the pump body and
wash it thoroughly with plenty of clean water. When finished and before
reassembly onto the motor body, lubricate the seal with silicone.
