This advice only needs to be followed in freezing conditions.
Make sure that the steam generator, hose and black box have been emptied of all water. Wherever possible bring the Hay Steamer into somewhere warmer where it can’t freeze.
Can you put a small heater into a tack room?
Is taking it home to use in a garage or warm space an option just while it’s freezing? If you can’t follow any of the steps above can you get a bucket of boiling/ hot water and put the plastic hose in prior to use to allow it to defrost also pour the water over the pipe work inside the box. Another option would be to take the steam generator and hose home overnight and wrap some rugs or insulation around the box to prevent it freezing.
Remember do not use the hay steamer if the hose or pipework is frozen as the steam escaping from the steam generator will not be able to escape and the pressure will back up inside the steam generator.
Another Handy tip is to always make sure that the pressure release valve at the top on the back of your hay steamer is clear of any hay or other dust and dirt. This is essential to ensure that the pressure valve is working as it should, always do this when the steam generator is unplugged and cold.
