Warning: Hot water bottles can cause burns. Avoid prolonged direct contact with the skin. This hot water bottle is made of natural rubber. When filling this hot water bottle, do not use boiling water and fill to a maximum of two-thirds capacity or less. Do not overfill as this might cause the bottle to burst. Hold the bottle by the neck in an upright position and fill slowly to avoid hot water splashing back. Expel air from the bottle by lowering it carefully onto a flat surface until water appears at the opening. Screw the stopper sufficiently tight to ensure that there is no leakage. Finger-tight should be adequate. Finally, make sure the funnel is empty. If there is a possibility that prolonged contact with the skin could occur, an adequate cover should be used to prevent burns. Even with cover, do not allow contact with one area of the body for a prolonged period of time. Under no circumstance should the hot water bottle be used as a cushion and be sat or laid on. Do not fill using water from the domestic hot water system as this can considerably shorten the life of the hot water bottle. Prevent contact with hot surfaces. Prevent contact with oil, grease and pointed/sharp objects. When not in use, drain completely and keep, with the stopper removed, in a cool, dry, dark place. Prevent exposure to sunlight. Do not place anything on top of the bottle during storage. Check the bottle and stopper for wear and damage prior to every use and replace if necessary. Please retain these instructions for future reference. We recommend that the hot water bottle should always be used with the cover provided. Not suitable for children under 3 years. Use under adult supervision only, do not leave children unattended with bottle. Please use common sense. This is not a toy. Keep away from fire and naked flame.
