A 1-12-2004 FCC INFORMATION This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation. Warning: Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: o Reorient or relocate the receiving antenna. o Increase the separation between the equipment and receiver. o Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. o Consult the dealer or an experienced radio/TV technician for help. INTRINSIC SAFETY INFORMATION The remote transmitter is Intrinsically Safe Apparatus for use in Class I, Division 1, Group D Hazardous (Classified) Locations per ANSI/UL 913 and CAN/CSA C22.2 No. 157 Securite Intrinseque: Ex ia Control Drawing # 040108A0001 1. WHEN INSTALLED AS SHOWN THE WIRELESS TRANSMITTER AND HALL SENSOR ARE INTRINSICALLY SAFE FOR HAZARDOUS LOCATION: CLASS 1, DIVISION 1, GROUP D 2. INTRINSICALLY SAFE WIRING MUST BE INSTALLED IN ACCORDANCE WITH ARTICLE 504 OF THE NEC ANSI/NFPA 70 OR IF APPLICABLE THE CANADIAN ELECTRICAL CODE. 3. WIRELESS TRANSMITTER AND HALL SENSOR SHALL BE INSTALLED IN ACCORDANCE WITH RS-228 INSTALLATION INSTRUCTIONS. 4. HALL SENSOR:: ROCHESTER GAUGES R3D SENSOR. 5. WIRELESS TRANSMITTER: ROBERTSHAW RS228 WIRELESS LP TANK LEVEL TRANSMITTER. 6. WARNING! TO REDUCE RISK OF IGNITION OF A FLAMMABLE OR EXPLOSIVE ATMOSPHERE, BATTERY MUST BE CHANGED ONLY IN A LOCATION KNOWN TO BE NON-HAZARDOUS. 7. WARNING: TO REDUCE THE RISK OF EXPLOSION, DO NOT MIX OLD BATTERIES WITH NEW BATTERIES, OR MIX BATTERIES FROM DIFFERENT MANUFACTURES. 8. WARNING! SUBSTITUTION OF COMPONENTS MAY IMPAIR INTRINSIC SAFETY. 9. WARNING! TO PREVENT IGNITION OF FLAMMABLE OR COMBUSTABLE ATMOSPHERES, DISCONNECT POWER BEFORE SERVICING. 4 RS-228IM Rev. A 1-12-2004 IMPORTANT Information Warning! – Substitution of Components May Impair Intrinsic Safety Warning! – To prevent ignition of flammable or combustible atmospheres, disconnect power before servicing. Warning! – To reduce risk of ignition of a flammable or explosive atmosphere, batteries must be changed only in a location known to be non-hazardous. Warning! – To reduce the risk of explosion, do not mix old batteries with used batteries, or mix batteries from different manufacturers. Caution! – Replace batteries only with two of each (3V total): 1. Duracell MN1500 LR6 1.5 volt AA alkaline batteries 2. Energizer 2012 L91 1.5volt AA lithium batteries 3. Novacell AM3 LR6 1.5V AA Alkaline Batteries. The following additional precautions should be observed: 1. Use only the type and size batteries specified in the user manual. 2. Do not dispose of the batteries in fire. They may explode. Check with local codes for possible special disposal instructions. 3. Do not open or mutilate the batteries. Released electrolyte is corrosive and may cause damage to the eyes, skin. It may be toxic if swallowed. 4. Exercise care in handling batteries in order not to short the battery with conducting materials such as rings, bracelets, and keys. The battery or conductor may overheat and cause burns. 5. Do not attempt to recharge the batteries identified for use with this product. The batteries may leak corrosive electrolyte or explode. 6. Do not attempt to rejuvenate the batteries identified for use with this product by heating them. Sudden release of the battery electrolyte may occur causing burns or irritation to eyes or skin. 7. When replacing batteries, all batteries should be replaced at the same time. Mixing fresh and discharged batteries could increase internal cell pressure and rupture the discharged batteries. 8. When inserting batteries into this product, the proper polarity or direction must be observed. Reverse insertion of the batteries can cause charging, and that may result in leakage or explosion. 9. Remove batteries from this product if the product will not be used for a long period of time (Several months or more) since during this time the battery could leak in the product. 10. Discard “dead” batteries as soon as possible since “dead” batteries are more likely to leak in the product. 11. Do not store this product, or the batteries identified for use with this product in high-temperature areas. Batteries that are stored in a freezer or refrigerator for the purpose of extending shelf life should be protected from condensation during storage and defrosting. Batteries should be s…
