Start-Up Procedure - Simpson IR61094 Instruction Manual

• DO NOT use hot water, use cold water only.
• Never turn water supply off while pressure washer motor is
running or damage to pump will result.
• DO NOT stop spraying water for more
than two minutes at a time. Pump operates
in bypass mode when spray gun trigger is
not pressed. When the temperature inside
the pump rises too high the thermal relief
valve (T) will open and release a gush of
water in an effort to lower the temperature
inside the pump. The thermal relief valve will then close. If pump
is left in bypass mode for more than two minutes internal
components of the pump can be damaged.
WARNING: Do not allow the unit to run for more than two
minutes without the gun trigger being pulled. This could cause
overheating and damage to the pump. When the temperature
inside the pump rises too high, the thermal relief valve will
open and release a spray of water from the pump to lower the
internal temperature. The valve will then close.
