Types of reservoirs
Interval of the level check
The liquid level of the cooling system must be checked on a regular basis. This must be done by a trained and qualified technician.
The interval depends on the size of the reservoir.
It must be checked before fi rst use of the projector! Once the projector has been used before, the cooling liquid level must be
checked on every lamp change or every three months (small container) or every six months (big container) , whatever comes
first. If the liquid level is not within the specifications, cooling liquid must be added.
