a. Avoid structures liable to vibration, e.g. crane gantries, which could otherwise adversely affect lamp life. b. The lamps are designed to operate within 5° of the horizontal plane. It is very important to ensure that the heater is mounted horizontally, otherwise the operating life of the lamp could be impaired. c. Ensure appliance is mounted the correct way up so that it can be tilted down but not up. d. WARNING – THESE HEATERS ARE DESIGNED TO BE WALL MOUNTED, BRACKET MOUNTED, OR SUSPENDED MOUNTED – THEY MUST NOT BE CEILING MOUNTED. THEY MUST NOT BE MOUNTED IN A ROOM CONTAINING A BATH OR SHOWER. DO NOT MOUNT HEATERS CLOSER THAN 3.5 METRES FROM CURTAINS OR SIMILAR SOFT FURNISHINGS. Electrical Wiring to the heater must be installed in compliance with the requirement of the IEE Regulations and any local or insurance regulations. All heaters are suitable for use on 230-240V single phase supplies. Wiring between the heater and the spur outlet or isolation switch must be in a heat resisting cable with a temperature rating of T150. Sufficient slack cable must be left to allow for angular adjustment of the heater body. An all-pole isolating switch with a minimum separation of 3mm in each pole must be fitted adjacent to the heater to facilitate local isolation. If miniature circuit breakers are to be used to avoid ‘nuisance tripping’ due to the high in rush at switch on, a type ‘C’ MCB with a tripping coefficient of 7-10 times rated current should be used. Any other switching device should be Tungsten lamp load rated. Always ensure that the cable grip is tightened. IMPORTANT Ensure the electrical supply cable is routed and restrained to prevent contact with the external surfaces of the heater and is not positioned in the direct heat beam. When heater is close to a ceiling the reflectors must be rotated to avoid the heat beam from directly overheating it. The reflector must point down at more than 30° from the horizontal. Always ensure that the heat beam is parallel to or angled away from a side wall when mounted close to and end wall to avoid overheating wall surfaces. The minimum distance to an end wall is 1.0m. It is important that the user is instructed not to stack inflammable material in the direct heat beam. Maintenance Since the Dimplex Vector Heater contains no moving parts little maintenance is required beyond cleaning and lamp replacement. It is however essential that the heater is not operated with accumulation of dust or dirt on the lamp(s) or reflector(s) as this can cause a build up of heat and eventual damage . For this reason the heater must be inspected regularly, depending upon conditions and at least at yearly intervals. Before undertaking any maintenance work on the heater due attention must be paid to the following, 1. Always disconnect the heater from the electricity supply before attempting to work on or near it. 2. Always ensure a safe means of access using an access tower or properly supported ladder. 3. Some types of quartz lamps run with an internal pressure in excess of atmospheric and while construction is very strong there is a slight risk of shattering. If it is necessary to examine a bare lamp whilst in operation then a protective screen must be used. 4. Allow adequate time for the lamps and body casing to cool before attempting to work on the heater. Inspection and Cleaning 1. Check that all the lamps are functioning. If any thermostatic or time controls are fitted ensure that the supply is ‘off’ before checking lamps. Any failed lamps should be replaced (see lamp replacement). Remove any accumulated dirt and check wiring and connections. 2. Clean the lamp(s) and reflector(s) using a mild detergent solution and soft cloth. Do not use any abrasive or caustic cleaners. Dry with a soft cloth. Avoid touching either the quartz lamp sleeve or the aluminium reflector with bare fingers. If they are accidentally touched remove any finger prints using a soft cloth moistened with methylated spirit. 3. Check that the lamp(s) are properly located in the spring retaining clips and that they have not been disturbed by cleaning. The lamps should be pushed fully back into the clips by applying light pressure on the end caps only. Safety in Operation The heater is operated by simply switching on the electrical supply, or, if used in conjunction with a control system, then the supplier’s instructions must be observed. ALWAYS disconnect the heater from the supply before attempting to work on or near it. NEVER operate the heater with a high accumulation of dust or dirt on the lamp(s) or reflector or with a damaged or corroded reflector. NEVER use the heater where flammable dusts, gases or vapours, etc., are likely to be present in the atmosphere. NEVER operate the heater in close proximity to the skin or eyes. NEVER allow materials which could be damaged or ignited by the radiated heat to be placed in close proximity to the heater. NEVER cover the heater – even when it is switched off. ALWAYS refer to...
