HUGFEN C31-2 - Manual (Page 4)

Health and Safety
Due regard shall be given to observing safe procedures when working with or on the equipment. It is the
responsibility of the Installer / Operator / Customer to ensure that the “Health and Safety at Work Act (1974)”
and Normal Safe Working Procedures are adhered to at all times.
With reference to the "Control of Substances Hazardous to Health Regulations 1988 (COSHH)” the following
paragraphs have been extracted from Denco’s letter responding to information requested
“However, certain substances contained within materials used in the manufacture of our units could be
hazardous when released, if the unit is misused, abused or maintained by unskilled labour.
Fumes would be released if pipework or slab foam insulation (Armaflex or similar), electrical insulation or vinyl
coatings were exposed to naked flame. It will be, therefore, that no naked flame should be applied to any of the
above mentioned substances, nor to print, rubber or plastic parts.
Light oil is applied to some bare metal parts as a protective coating and this could cause dermatic reaction to
sensitive skin.
Refrigerants contain hydrofluorocarbons (HFC’s). Glycol/water mix is used during manufacture but drained
before delivery. The quantities in use are minimal but care should be taken in disposal.
We trust that this information is sufficient but should you require further information regarding our products or
maintenance service, please contact our sales department.”
