A. The hose can quick disconnect from the pump
and left 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.
• Do not use the pump to fill the system to be tested with
water. Fill the system prior to attaching the pump, then
attach the pump and pressurize the system.
• 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.
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.
