a. Consult local electric code and authority having jurisdiction before operation. Make sure the electrical installation is compatible with the voltage stated on the nameplate. b. Examine the vacuum cleaner system’s power cable for damage (cracking or ageing) before use. Return to manufacturer for servicing if damaged. Use only the power cable supplied with the unit or one purchased from the manufacturer.
5.0 PRECAUTIONS FOR THE RECOVERY OF HAZARDOUS MATERIALS WARNING: Model 61461 / EXP1-IT 85 EX CFE not equipped with a HEPA filter is not suitable for the recovery of hazardous materials. DANGER: If the vacuum cleaner is used to recover toxic or nuisance materials, the following safety precautions must be taken: a.
6.0 GROUNDING INSTRUCTIONS This vacuum cleaner system must be properly grounded. If it should malfunction, or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This vacuum cleaner system is equipped with a cord having an equipment-grounding conductor.
7.0 TESTING FOR GROUND CONTINUITY WARNING: Test the electrical continuity of the vacuum cleaner before use. This will ensure that any static electricity that is produced while vacuuming will be discharged to ground. WARNING: Use only original replacement parts from the manufacturer or from one of its authorized distributors.

12.0 ASSEMBLING AND REPLACING THE HEPA FILTER A HEPA filter is designed for filtration of ultra-fine particles. A clogged HEPA filter will reduce the air flow thereby reducing the vacuum’s performance thus requiring replacement. The life of the HEPA filter depends greatly on the use of the vacuum cleaner system. The best indication of a saturated HEPA filter is a noticeable drop in the performance of the vacuum cleaner system.
