Generally speaking good copy; a few pages too hard contrast...
Good service and communication.

I purchased the unit from a private party and the original owners manual was not available. Having the ability to download it was extremely helpful and clarified operating the equipment immensely. This is a complicated unit and without the manual I would not have been able to maximize it's potential. Thank you.
English 19. Thermal protection
A thermal sensor in the body of the iWASH 575 EB protects the unit against overheating. The thermal sensor removes power from the lamp should the ambient temperature exceed the set maximum or if there is a lack of air flow or there is a fan malfunction.
20. Lamp circuit protection
Two timers operate simultaneously within the projector to protect the lamp ignitior and power supply against prolonged operation in non-ideal conditions. A protection device, inside the electronic ballast, impedes attempts to power up the lamp for more than 3 seconds if the lamp has failed to ignite. The device will automatically attempt to restart the lamp for a further 3 seconds in every minute. A software timer reattempts lamp ignition for a period of 20 seconds in every minute for up to 8 minutes; then it preserves the lamp circuit by not allowing high voltage to the lamp (assuming the lamp to have passed its useful life). The display will show
LAER (lamp circuit error) each time an unsuccessful attempt is made to turn on the lamp
NOTE: it is important to remove power from the fixture if the lamp has reached the end of its life and to replace the lamp.
21. Maintenance
Whilst every possible precaution has been taken to ensure the trouble-free operation of your IWASH 575 EB, the following periodic maintenance is highly recommended. All maintenance should be effected with the power to the unit switched off
Attention
Disconnect mains power prior to removing the projector housing. To gain access to the internals of the unit refer to section 17. Opening up the projector.
periodic cleaning lenses and reflectors
Even a fine layer of dust can reduce the luminous output substantially. Regularly clean all lenses and the reflector using a soft cotton cloth, dampened with a specialist lens cleaning solution.
fans and air passages
The fans and air passages must be cleaned approximately every 6 weeks; the period for this periodic cleaning will depend, of course, upon the conditions in which the projector is operating. Suitable instruments for performing this type of maintenance are a brush and a common vacuum cleaner or an air compressor.
periodic maintenance lamp
The lamp should be replaced if there is any observable damage or deformation due to heat. This will avoid the danger of the lamp exploding.
mechanicals
Periodically check all mechanical devices for wear and tear; gears, guides, belts, etc., replacing them if necessary. Periodically check the lubrication of all components, particularly the parts subject to high temperatures. If necessary, lubricate with suitable lubricant, available from your coemar distributor.
electrical components
Check all electrical components for correct earthing and proper attachment of all connectors, refastening if necessary.
fuse replacement
Locate the fuse, which protects the lamp and electronics, in the base of the iWASH 575 EB. Using a multimeter, test the condition of the fuse, replacing it with one of equivalent type if necessary.
