Dear valued customers:

Low temperatures and rain/snow weather have arrived. In some areas, daytime or nighttime temperatures have dropped significantly to 0°C or below. Failure to drain water from the high-pressure pump can lead to freezing. Water remaining in the pump head and plunger can freeze, expanding and cracking the pump housing. Starting the pump before the ice has completely thawed can also cause plunger breakage and deformation of related parts. Therefore, please pay attention to the impact of ice formation on the equipment.

To ensure the safe and normal operation of the high-pressure pump and prevent damage caused by low temperatures and freezing weather, the following measures for preventing and thawing high-pressure cleaning equipment are proposed:

1. Add insulation measures to the high-pressure cleaning vehicle to prevent the high-pressure pump, water pipes, and water lines from freezing.

2.  When not using the high-pressure cleaning vehicle, store the high-pressure cleaning equipment indoors at a temperature above 0°C to prevent freezing.

3.  It is recommended that before stopping the use of the high-pressure pump, inject a non-corrosive antifreeze solution into the water inlet to protect the pump head and high-pressure pipes from freezing damage.

4. Drain any unused pumps on the high-pressure cleaning vehicle, and drain the water from the water tank, water pipes, and other water lines. The specific operation process for draining the high-pressure pump is as follows: Close the high-pressure water inlet (to prevent water in the tank from entering the high-pressure pump) → Remove the nozzle from the reel → Start the high-pressure pump (running at idle speed) → Observe the reel hose until no more water comes out → Stop and turn off the high-pressure pump → Open the three plugs below the hydraulic end (pump head) of the high-pressure pump, and use a thin rod about 15-20 cm long to push upwards from the circular hole where the plugs are installed until a spring is felt, and a small amount of water will flow out. Repeat this several times until no more water flows out.

5. When the outside temperature drops to 0°C, the water in the water tank will become a mixture of ice and water (appearing as a flocculent substance). When using the high-pressure pump at this time, the ice-water mixture will adhere to the filter screen when passing through the filter system of the water inlet pipe, resulting in insufficient water supply. The hose may shake when the high-pressure pump is used. Inspection and troubleshooting should be carried out in advance to avoid hose shaking.

6.  Freezing of the high-pressure cleaning equipment will damage the seals in the high-pressure pump, reducing sealing performance.

7.  If ice is found in the water inlet pipe, high-pressure pump, or water outlet pipe before using the high-pressure cleaning vehicle, do not start the high-pressure pump, and do not use hot water to pour or rinse to thaw, to prevent excessive temperature difference from causing cracks in the equipment and causing losses. Warm water can be used to thaw, or the high-pressure cleaning equipment can be placed at room temperature for natural thawing.

8. Operate only after the high-pressure cleaning pump and accessories are completely thawed. Refer to the above antifreeze measures when stopping use.

9.  The antifreeze and thawing of the high-pressure pipe can refer to the antifreeze and thawing measures for the high-pressure cleaning pump.

10.  If the high-pressure cleaning equipment is frozen and forcibly started, the springs, valve covers, and other working components in the hydraulic end of the high-pressure pump will be deformed and damaged, resulting in hose shaking. In severe cases, it can lead to serious consequences such as cracking of the high-pressure pump power end.

Damage to the pump and its accessories caused by failure to drain water and starting the pump with ice is due to natural factors and human operation, not a product quality problem, and is not covered by free maintenance. Please pay attention and take protective measures to avoid property losses.
