Section 6
Maintenance
Warning
To reduce risk of electric shock, disconnect unit from power
source before servicing.
s
Before re-applying power, after maintenance is complete, check to ensure
that safety ground is intact and making a good connection.
Disconnect incubator from power source. Immediately clean all spilled
materials from the incubator and wipe dry. If necessary, moisten a cloth
with soap and water and clean inside and out. Do not use any harsh
chemical cleaners.
Periodic defrosting may be necessary. The time between defrosts depends
on operating temperature, ambient humidity and moisture from samples.
Time between defrosts may be from 30 days to years. Defrosting may be
necessary when operating at 50% mode as well, especially for control
temperatures less than 15.0°C.
Method I:
For control setpoint down to 10°C, this method is the least
disruptive, if samples can withstand temperature stability of ±1.5°C for 24
hours. Samples may remain in chamber during this procedure.
1. (Refer to Accessing Controller Menus) Press and hold MENU key
until CAL is displayed, then release and press MENU again until Pct is
displayed.
2. Select 50 in the Pct menu then press MENU key twice to return
control mode.
3. Allow incubator to remain in this mode for about 24 hours or until
frost disappears.
4. Use the MENU key to re-establish the previous selection for Pct (i.e.
100).
