5. Installation

This pump is designed for horizontal mounting and can be oriented in any direction that allows for accessible hose connections. The pump head cannot be flipped, but the entire pump unit can be mounted in different directions to suit your pressure washer's configuration.

General Installation Steps:

1. Preparation: Ensure your pressure washer unit is turned off, unplugged (if electric), and depressurized. Disconnect all hoses.
2. Remove Old Pump: Carefully detach the old pump from the engine/motor. Note the mounting bolt locations and shaft connection.
3. Inspect Shaft: Ensure the engine shaft is clean and free of debris.
4. Mount New Pump: Align the new Himore pump with the engine shaft and mounting holes. Secure it using the appropriate bolts. The 4-bolt pattern is 2 5/8" center to center between outer holes.
5. Connect Hoses: Connect the standard garden hose to the inlet and the 22mm male high-pressure hose to the outlet. Ensure all connections are tight to prevent leaks.
6. Chemical Injector: Connect the chemical injector hose if you plan to use detergents.
7. Thermal Release Valve: Ensure the thermal release valve is properly installed and clear.

Refer to your pressure washer's original manual for specific instructions on pump replacement if available.

6. Operation

Once the pump is correctly installed and all connections are secure, you can begin operating your pressure washer. Always follow the safety guidelines outlined in Section 2.

Starting the Pressure Washer:

1. Water Supply: Connect a garden hose to the pump's inlet and ensure the water supply is turned on fully.
2. Purge Air: Squeeze the trigger on the spray gun to purge air from the pump and hose until a steady stream of water emerges.
3. Start Engine/Motor: Start your pressure washer's engine or turn on the electric motor according to its manufacturer's instructions.
4. Begin Cleaning: Release the trigger to allow the pump to build pressure, then squeeze the trigger to begin cleaning.

Using the Chemical Injector:

If using detergents, ensure the chemical injector hose is submerged in the detergent solution. The chemical injector typically operates at low pressure. To apply detergent, switch to a low-pressure nozzle or adjust the spray gun as per your pressure washer's instructions.

7. Maintenance

Regular maintenance is essential to ensure the longevity and optimal performance of your Himore pressure washer pump.

After Each Use:

• Flush System: Run clean water through the pump to flush out any remaining detergent or debris.
• Drain Water: Disconnect the water supply and squeeze the spray gun trigger to drain any remaining water from the pump and hoses.
• Clean Exterior: Wipe down the pump's exterior to remove dirt and grime.

Seasonal/Storage Maintenance:

• Winterization: If storing in freezing temperatures, use a pump saver or non-toxic antifreeze solution to protect the pump from freezing and corrosion.
• Inspect: Periodically inspect hoses, connections, and the pump for any signs of wear, damage, or leaks. Replace worn parts as necessary.

8. Troubleshooting

This section provides solutions to common issues you might encounter with your pressure washer pump.

Common Issues and Solutions:

• No Pressure or Low Pressure:
  • Check water supply: Ensure the garden hose is fully connected and the water tap is completely open.
  • Air in system: Purge air from the pump by squeezing the spray gun trigger until a steady stream of water flows.
