11. NOTES

All repairs should be performed by qualified certifiers only. If you do not have a certifier that you work with,

please contact DFMZ and we can help you find a qualified certifier in your area.

Please make sure that all electrical requirements are met before connecting and using this equipment. This

equipment requires a three prong outlet. DO NOT remove the third prong in order to use an incompatible

outlet. If necessary, contact a qualified electrician to install a properly grounded three prong outlet.

Maximum weight of objects on the work surface should not exceed 23 kg or 50 lbs.

If possible, try to avoid the use of equipment that could shake or vibrate the hood (such as a centrifuge or

spiral oscillator). The vibrations given off by this type of equipment can lead to shedding of particles from the

HEPA filter, resulting in unclean work area or exposure to the operator.

NEVER USE OPEN FLAME INSIDE CABINET – open flames will disrupt the airflow and cause damage to the

filter. If high temperature sterilization is required, this should be done outside the cabinet.

HEPA filters have a limited service life up to several years but they CANNOT be cleaned. Debris accumulates on

the face of the filter, leading to pressure drops. Contact your certifier for service/HEPA filter replacement.

All sealed openings on the cabinet should not be tampered with. If a situation arises where access is required,

please contact a qualified certifier or DFMZ for assistance.

Storage period for this equipment is one year. Following any extended storage, the equipment should be
