Curtain Assembly Replacement
Dymax recommends that you check the ZIP Shutter curtain for wear each time you change the lamp. If it
shows any signs of wear, replace it. Additional curtain assembly replacements can be purchased through
Dymax Customer Service.
CAUTION! SHARP EDGES!
The edge of the stainless steel curtain is extremely
sharp. To prevent injuries, always wear gloves that are resistant to cuts when handling or
installing equipment. We recommend, at a minimum, CE Cut Level 5 gloves (included with
kit).
