INSTALLATION OF THE DISCHARGE LAMP MSD 1200W, MSR 1800W

IP RATE - INSTALLATION OF THE DUST PROOF FILTERS

The declared IP rate of the Sirio RAY 1200/1800 comes supported at these conditions:

• the installation of the fixture on a wide and stable surface

• the air cooling input and output are located on the base of the side-shell,

The Sirio RAY 1200/1800 has a IP rate 44 without filters installed and an IP RATE 54 with filters installed.

You must use the filters in critical working conditions and, normally, when the fixture works outdoor.

You must remove the filters when the ambient temperature is over 35°C.

You must regularly clean the filters to allow the correct cooling of the fixture.

You must remove the two side protective shells. The two filters must be

assembled on the bulkheads at the bottom of the side brackets.Pay attention to the

installation: dust proof filters must stick correctly to prevent the entrance of the dust.

You must control that the two filters completely cover the overall of the air entrance.

You must operate with power

supply disconnected from the fixture.
