Thermal Relief Valve; Pre-Start Inspection Procedures - A&I Products PW-1500E Manual Del Operador

INSTALLATION & PREPARATION

THERMAL RELIEF VALVE:

To ensure the bypass water temperature does not exceed acceptable levels,
never allow the pressure washer to operate in the bypass mode (with the unit
running and the trigger closed) for more than three minutes.
A thermal relief valve has been added to this unit to protect the pump. It may begin
to open and release water if the water temperature in the pump has exceeded
40° F. This will allow fresh, cool water to enter the system, therefore preventing
premature failure of pump packings.

PRE-START INSPECTION PROCEDURES:

Before starting the unit, perform the following procedures:
. Check the oil level in the pump.
2. Inspect the inlet water strainer. Clean or replace if necessary. See "Water
Supply", #2, pg. 11.
3. Check all hose connections to ensure they are securely tightened. See
"Water Supply", #3, pg. 11.
4. Inspect for system water leaks and oil leaks. Be sure that all damaged
parts are replaced and that the mechanical problems are corrected prior
to operation of the unit. If service is needed, contact Customer Service.
5. Inspect high pressure hose for kinking, cuts or leaks. If a cut or leak is found,
DO NOT USE HOSE! Replace hose before starting unit. See "Miscellaneous
Safety Precautions" #6, pg. 6. Be sure that all damaged parts are replaced
and that the mechanical problems are corrected prior to operation of the
unit. If you need service, contact Customer Service.
6. Inspect electrical cord for cuts. If a cut is found, DO NOT TOUCH OR USE
ELECTRICAL CORD! Replace cord before starting the unit.
