5. The system is now isolated.
A. The hose can quick disconnect from the pump and remain
with the system being tested, if necessary, so that the
pump can be used to test another system or stored.
WARNING: Protect the pump from freezing. Store and
transport in a warm place. Or use food grade propylene
glycol in the pump to guard against freezing.
Safety and Precautionary Instructions:
• Do not use a damaged or worn High Pressure Hose.
• Do not run the pump without a water supply.
• Before storing the pump, flush it with clean water and
then operate it with a solution of water and food grade
propylene glycol to protect and lubricate the internal parts.

TROUBLESHOOTING

Pump Loses Pressure: Do not run the pump without the washer
screen #98180 in the intake. Debris may cause damage to the
pump or may cause the pump to loose pressure. If the pump does
not build pressure, there may be debris lodge in the check valves.
There are two check valves under each end cap. Remove the end
caps using a 5mm hex wrench and inspect the check valves. If the
issue is not solved, the pump seals may have to be replaced using
Seal Kit #48181.

PERIODIC MAINTENANCE:

Every 100 hours, inspect and lubricate the piston and bearing.
This is behind the front cover plate of the pump. To access this
area, remove the four screws and take off the cover plate. Do not
remove the front cover plate while the pump is plugged in or run-
ning. Never run a pump without reinstalling the front cover plate.
Lubricate with a water resistant, all-purpose lithium grease.
