Installing Glycerine Solution in Product Simulation Bottle -
Required
ATTENTION INSTALLER
§It is imperative that the top/bottom probe bottle be lled with a solution
that your facility uses to ensure proper operation of unit.
§Units are equipped with a third-party monitor installation port.
Customers are required to refer to CDC Vaccine and Handling Toolkit
(cdc.gov) for proper placement of the probe within the cabinet to
ensure proper performance.
§NSF 456 requires the temperature display probe (P4-RTD1 in
REF12, REF20/25, FZR20/25, and REF45 models) to be replaced or
recalibrated. Follett recommends replacement/recalibration 12 months
from the original date of calibration on the Certicate of Traceability
supplied with your equipment at the time of purchase. Recalibration
or purchasing a new calibrated probe is not covered by the original
equipment warranty. To purchase a new Probe with Certicate of
Traceability, please contact our Parts Department @ 1-877-612-5086 or
[e-mail]
