The voltage tolerance for each model is shown on the respective wiring diagram in this Manual. . The dryer must be fully isolated from the supply BEFORE maintenance work is started. . The dryer MUST NOT be used on other supplies without prior approval from the manufacturer. . The dryer should only be used in a SAFE (i.e. non- hazardous) area. . Observe any electrical safety labels fitted to various parts of the dryer. . Solenoid coils should not be removed from valve stem until they have been electrically disconnected. Refrigerant Safety Data Reactivity Data Stability Unstable Conditions to Avoid Use in presence of naked flames, red-hot surfaces. High moisture levels Stable YES Incompatibility (Materials and Conditions to Avoid) May react violently with sodium, potassium, barium or other alkali or alkaline earth materials. Magnesium and alloys containing more than 2% magnesium. All finely divided metals. Hazardous Decomposition Products Halogen acids formed by thermal decomposition. Fire and Explosion Hazard Data Flash Point (oC) Method ---- Auto- ignition Temperature (oC) --Flammable Limits (% by Vol. in Air) Lower Upper Non Flammable ---- Would any material saturated Materials: with this product be subject to spontaneous combustion? No Fire Extinguishing Data Non flammable, not combustible. Special Fire Fighting Procedures Fire exposed containers should be kept cool with water sprays. Usual Fire and Explosion Hazards Will decompose in contact with high temperature sources, i.e. flames, electric arcs, etc. to produce irritating and highly toxic acidic products. Breathing apparatus should be worn if refrigerant is exposed to fire conditions. Containers may burst if overheated. Precautions in Handling and Use General Precautions Atmospheric levels should be minimised and kept as low as reasonably practicable below hygiene standard. Avoid inhalation of high concentrations of vapour. Heavy vapour collects at low levels. Ventilate by extraction at lowest level. Decomposes in flames, arcs and at red heat to toxic acid by-products. Avoid contact between liquid and skin or eyes. Ventilation Requirements Respiratory Protection Ventilation may be required to achieve a sufficiently Where doubt exists on atmospheric concentration and low exposure level. Extract at lowest level. Vapour particularly in confined spaces, self-contained collects in pits, trenches, basements, sewers and in breathing apparatus should be considered. Breathing confined spaces and vessels. apparatus should always be worn in a fire situation. Protective Clothes Where liquid splash is a possibility gloves suitable for use in low temperatures should be worn e.g. chlorobutyl rubber with cotton liners. Overalls. Eye Protection Goggles. Storage Containers should be stored in a cool dry place away from fire risk and sources of heat. They should not be exposed to direct radiation from sources of heat such as steam or electric radiators. Do not heat containers beyond 45oC. Health Hazard Data and First Aid Short term effects of over exposure when: In contact with skin: Liquid splashes may cause freeze burns. No information found on irritancy or sensitisation. There is no known hazard due to absorption through the skin. In contact with eyes: Liquid splashes or vapour spray may result in freezing of tissue or eye fluids. Inhaled: Very high concentrations may produce anaesthetic effects and can act as an asphyxiant by limiting available oxygen. They also may prove suddenly fatal (cardiac sensitisation). 10 min effective concentration 50 28% (Rat) 15 min lethal concentration 50 > 80% (Rat) 4 hr lethal concentration 50 > 50% (Rat) Threshold for cardiac sensitisation 7.5% 5 min (Dog) Ingested: Extremely unlikely to occur under normal industrial use. Should this occur freeze burns will result. Long term effects of over exposure: No effects have been seen in rats exposed to ...
