Page 6: Installation
III. Installation Line Sizing Contact Haskris for help: Haskris is available to review pipe runs, pressure drop, etc. and make recommendations for individual sites. Approach to line sizing • Size all interconnecting hose and piping equal to or larger than the connections on the unit. - Page 7 • If the total straight pipe length is less than 200 ft (61.0 m) use 2” nominal pipe size (ID). • If the total straight pipe length is less than 510 ft (155.4 m) use 2-1/2” nominal pipe size (ID).

Page 10: Filling The Reservoir
• Make sure additional water is on hand when the unit is started up to top off the liquid level as the external piping is filled. • Note: Some units are designed for compatibility with other fluids. Contact Haskris if you are unsure what fluids are compatible with your unit. -
Page 11: Startup
Operation: Toggle the switch to the ON position to make the unit run. Toggle the switch to the OFF position to make the unit stop. If a fault occurs, toggling the switch to OFF and then back ON will reset the fault. ON/OFF switch examples Phone: 001 847 956 6420 Email: service@haskris.com Page 11 of 25... -
Page 12: Pump Priming
Pump Priming Purpose: All fluid is removed from the pump head prior to shipment from Haskris. When starting the pump, it needs to be filled with fluid. This process is called priming the pump. When the reservoir is full, the pump suction line is “flooded”. In most cases, this flooded suction will automatically prime the pump. -

Page 23: Maintenance
Maintenance: Record the pump’s running fluid pressure at the completion of startup when the filter is clean. Replace the filter when the pressure increases 5psi to 6 psi (0.3bar to 0.4 bar) above the startup running pressure. Replacement filters are available from Haskris.

Page 24: Wye Strainer
10 psi (0.7 bar) or more. Phone: 001 847 956 6420 Email: service@haskris.com Page 24 of 25... -
Page 25: Liquid Level And Water Quality
Glycol: If biological growth persists even after regularly changing the water and flushing the system, use laboratory/food grade (99% pure) propylene glycol to create a 10% mixture. Haskris recommends that additives be used only as a means of last resort.
