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.
An air inlet, impurity or chemical damage to a seal can interrupt the dosing function.
It is recommended to periodically check that the solution is being correctly drawn up
into the MixRite.
Change the suction tube as soon as it seems damaged by the chemical.
It is advised to relieve the pressure after use.
