Preparing System for Priming
Preparing System for Priming
Risk of bodily injury or property damage.
•
Do not over torque the plug. If leaking occurs shut off the water supply, remove the plug and reapply
PTFE tape to the plug as required before re-installation and air bleeding.
Risk of damage to equipment.
•
Do not apply power to the system until the pump is primed.
•
Do not run the pump dry, which can cause overheating and damage to the unit. This will void the
warranty.
•
Never loosen the air bleed plug while the pump is on.
Do not apply power to the system until priming the pump as directed.
•
There is an internal check valve built into the unit that needs to open during priming.
•
The design requires that the priming water has an
incoming pressure of 1.5 psi (0.1 bar) minimum. This is
especially important if the application involves boost-
ing water out of a shallow cistern.
There are two ways to accomplish this in the suction plumbing:
IMPORTANT: Do not completely remove the air bleed plug. A
maximum of 2 total turns should allow proper bleeding.
Normal Priming
1.
Pour water through a 3 feet (91 cm) vertical water column
to achieve 1.5 psi (0.1 bar) on the inlet.
2. Keep the inlet valve closed and unscrew the air bleed plug
slowly allowing air to escape until all air is purged from the
unit.
3. Close the air bleed plug.
Insert Priming
1.
Connect a working garden hose to a fitting on the inlet side
of the pump.
2. Keep the inlet valve closed, slowly turn on the garden hose
water supply
3. Carefully unscrew the air bleed plug until all air is purged
from unit.
4. Re-tighten the air bleed plug.
