If you are in any doubt about following the procedure below, please contact us for technical assistance. The mains power should
be disconnected before any attempts are made to replace the lamp. The following should be carried out with compliance to
latest IEE regulations. Please read the notes on the previous page with regards to handling and buying a replacement emitter
before proceeding.
1. Ensure the heater, emitter and on models with lights the bulbs are cool and the power supply is disconnected by removing the plug(s)
from the socket outlet.
2. Providing there is reasonable access and you are standing on a safe and stable platform, the emitter can be replaced with the heater
still mounted. Otherwise, remove the heater from its mounting and work on a safe, flat surface.
3. Remove the screws from the terminal box (Fig. 1) and lift off the cover.

6. Slide out the side covers from both ends and slide out the guard from either end (Fig. 3 & 4 shows side covers with lenses for models
with lights).

It is very important that your replacement light bulbs are exactly the same as the ones it was supplied with. These bulbs have been
designed to withstand high temperatures so failure to fit the exact same type could cause the unit to fail or even become dangerous.
Please contact Tansun Limited to purchase your replacement light bulbs and state the model number of the heater you wish to fit the light
bulbs to.

Your new emitter should not be handled with bare hands.
Remove finger marks with a soft cloth and methylated spirits or alcohol. Finger marks will burn into quartz causing premature lamp failure.

7. Firstly remove the two screws as highlighted on the right of Fig. 5 to remove the side reflector. If your heater is a model with lights models
you should then remove the two screws holding the bulb plate as highlighted on the left of Fig. 5 to allow the bulb plate to be lifted. Repeat at
opposite end.

8. Starting at the end where the emitter wires are fed through the gasket into the terminal box, if the heater has lights hold the bulb plate out
of the way (Fig. 6) or if it is a heater only the wires will be clearly visible, gently pull the lamp wires through the body of the heater so the
wires exit the terminal box (Fig 6).

9. At the opposite end of the heater, if the heater has lights hold the bulb plate out of the way (Fig. 7) or if it is a heater only the wire will be
clearly visible in the feeder tube, gently pull the lamp wire out of the tube.
10. Pull the emitter wires through the side reflector bracket and then one at a time pull the spring clips back and lift up the ceramic caps of
the emitter to remove it from the heater.
11. The emitter should now be removed from the heater. Refit the new emitter in reverse order ensuring the ceramic caps are correctly
seated in the lamp holders, no wires are trapped and all screws are fully tightened.
