Hydraulic Connection
The flow connection will always remain in the upper part of the pump from where the tube goes to the system to be
treated. The suction fitting therefore will always be in the lower part of the pump, where the tube with the filter will be mounted
that goes to the container of the liquid to be metered.
1. Remove the seal on the nut (2)
2. Insert the pipe through nut (2) and
the bushing (3)
3. Push the end of the tube (1) on the
conical spout of the nozzle (4)
4. Pull the nozzle (4) on the connector
(5)
5. Tighten the nut (2) on the connector
(5)
To prime the pump, connect the discharge tubing and follow the sequence shown in Figure 5.
If you are experiencing difficulty in priming the pump, then with a syringe withdraw the additive from the bleed nipple
reducing the number of impulses delivered by the device.
