INSTALLATION (CONTINUED)

The lamp head assembly can also be placed on a shelf type structure, supporting the unit by
its bottom outside edges. For this type of mounting, a windowed hole must be cut in the shelf,
which would provide adequate clearance for the unit’s bottom-side light exposure opening,
and also for the cooling air exhaust holes.
2.3 Shielding
All installations should incorporate adequate shielding of radiated UV light, in order to prevent
eye and skin burn of the operator or others passing through the work area (refer to UV Safety
Warning in the following Safety Considerations section of the manual). The supplied UV1428
closed headrest or UV0539 headrest / curing chamber can be used with the PortaRay to
minimize the amount of stray UV light scattering in the work area. Custom shielding may be
constructed using sheet metal, welding curtains, UV blocking acrylic or polycarbonate to
prevent operator exposure to UV radiation.
WARNING:
To prevent risk of eye or skin burn, all personnel must be protected from
direct or indirect exposure to the UV light produced by the PortaRay curing system.
Extreme care should be used when designing custom UV shielding to insure
personnel will not be exposed to harmful UV radiation. Additionally, UV protective
glasses and protective clothing should be used at all times while working in the vicinity
of the UV curing system.
