When a Hotpack is new it will required longer soaking than normal and will absorb up to three times its own volume of water. Place the hotpacks in the heating unit. Make sure that the water covers the body of the hotpack and bring to the boil. Allow to simmer for at least half an hour. Once the hotpack has been soaked it will need only about 10 minutes to prepare it for use. Fold a heavy turkish towel into four or six folds and place on the area to be treated. Carefully remove the hotpack from the water by the loops, wrap it in another towel and place on top of the folded towel.
The steam will penetrate the towel layers and provide effective moist heat for about 30 minutes. To minimise heat loss upwards, cover the application with another towel. If too much heat is being received increase the number of layers of towel between the hotpack and the treatment area. As the heat subsides, reduce the number of layers.
The unit is made of stainless steel and supplied with a basket and support hooks for standard hotpack bags, it is fitted with a safety thermostat.
During normal operation the hotpack heater will become hot. Precautions must be taken to avoid accidental burns. It is recommended that suitable protective wear is issued to the user to minimise the risk of scalds or contact with drips from hot hotpacks.
Do not allow the heater to run dry or boil continuously. Turn the heater off when not in use.
