If the single-fuel LPG kit is installed in the K25 and the pressure relief valve 8 freezes, the following important conditions may result:
1. Antifreeze is not filled up
2. There are bubbles inside the antifreeze, which are collected at a high point, including the water circuit of the pressure reducing valve, and need to be exhausted
(Please refer to K25 for filling water and releasing bubbles)
3. Whether the circulating water pipeline 5 is unobstructed and whether the pipe diameter can guarantee the flow
4. The height of the water pipe is too high, and the flow of water to the high place is very small
5. Whether the heavy load operation is performed directly after idling or immediately after starting, resulting in the water temperature not increasing, but the pressure reducing valve cooling too much.
Especially in some northern regions and cold winter areas, it is necessary to run at idle speed to normal water temperature before performing forklift operation.
This situation is more obvious if the forklift is equipped with a heater.
6. The thermostat will limit a certain amount of water flow, and it may freeze when exposed, resulting in the water flow not being smooth after the hot car. Consider removing this part
