use.
Refrigeration Module Operation
Under a no-load condition, the FreeZone Single Stage Freeze Dry
System can achieve a collector temperature of –50°C or lower
when the system is under vacuum, within 30 minutes when the
vacuum pump is running, depending on ambient temperature and
humidity.
If any repairs are required on the refrigeration module, contact
your local laboratory supply dealer. If your laboratory supply
dealer is unable to provide assistance, please call Labconco.
Repairs should only be undertaken by a competent refrigeration
technician or through an authorized Labconco service agency.
