• Page 6 - English - : 5 COMMISSIONING 1 Checks on the electrical installation should include earth continuity and insulation tests and must be undertaken by a competent person 2 Ensure that all the electrical connections at the lamps and the terminal rails have been made correctly that they are tight and that there is no loose or frayed wire 3 Replace and secure the terminal cover and replace and secure the front panel 4 Check that the mounting bracket is securely xed in the vertical position such that the lamps remain in a horizontal plane at all angles of heater displacement 5 Roughly align the heaters and tighten the adjusters 6 Switch on the heaters and check that the lamps are all operating If time or temperature controls are tted check these for correct and safe operation by reference to the suppliers instructions 7 Make any adjustments that are necessary to give an even spread of heat over the required area This may be done simply by perception of the heating effect or by using the distribution of visible light either at night or by darkening the room Hand over Hand over these instructions and make sure the user is familiar with all aspects of operation and safety including the need for regular cleaning and an annual inspection In the event of the premises being unoccupied then leave heaters switched off and isolated from the electrical supply Leave instructions adjacent to the electricity meter 6 MAINTENANCE Since the Dimplex Quartz 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 lamps or reectors 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 pressure 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 7 LAMP REPLACEMENT WARNING BEFORE UNDERTAKING THIS TASK ENSURE THE HEATER IS DISCONNECTED FROM THE ELECTRICITY SUPPLY 1 Detach heater from its mounting position 2 Unscrew the front panel by loosening the corner xing screws and then lift front panel clear 3 Disconnect the wires to the old lamp by removing the lock nuts retaining the terminal ends adjacent to the lamp clips Do not slacken the screws as this could disturb the internal wiring 4 Remove the lamp by gently releasing the ends from the spring clips Keep the lamp secure and do not twist the ends or apply undue force IMPORTANT Release and retain the high temperature cable ties from the element wires These must not be substituted 5 Before removing the new lamps from its protective packing it is important to be aware that quartz lamps are fragile and must be handled with care at all times Avoid touching the surface of the quartz sleeve with bare ngers If the sleeve is accidentally touched remove the nger print with a soft cloth moistened with methylated spirit 6 Hold the lamp rmly but gently at each end and offer up to the spring mounting clips The wire leads should face towards the front of the heater Push the lamp fully into the clips taking care to keep it square Do not twist the ends or apply undue force If either end of the lamp will not easily engage in the spring clips remove the lamp and gently ease the spring 7 The wire from each end of the lamp must be connected to the threaded connector ON THE SAME CLIP AS THE LAMP END With the outside not loosened insert the spade between the two outside nuts and tighten rmly 8 When the lamp has been tted check that the electrical connections have been correctly made Reuse the same cable tie to tether the element wires in place Ret the front panel checking that wires are not trapped
• Page 7 - English - : INSPECTION AND CLEANING 1 Check that all the lamps are functioning If any thermostatic or time controls are tted ensure that the supply is on before checking lamps Any failed lamps should be replaced see lamp replacement Remove any accumulated dirt and check wiring and connections 2 Clean the lamps and reectors 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 reector with bare ngers If they are accidentally touched remove any nger prints using a soft cloth moistened with methylated spirit 3 Check that the lamps 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 for 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 suppliers 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 lamps or reector or with a damaged or corroded reector NEVER use the heater outside or in contact with water NEVER use the heater where ammable 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 these instructions before attempting to dismantle the heater AFTER SALES SERVICE Your Dimplex Quartz Heater is guaranteed for one year from the date of purchace We undertake to exchange or repair free of charge within this period any part found to be defective due to a manufacturing fault Should you require after sales service please get in touch with the supplier through whom you purchased the appliance or the contact number on your Warranty leaet Please do not initially return a faulty appliance or part of an appliance as this may result in transit damage andor delay in providing service Let us know your difculty quoting the model number and series letter of the appliance We will then take the appropriate action
