4.3.1  Cleaning 

Regular and thorough cleaning will help to ensure best performance. 

 

Clean the chamber and machine compartment drain pans and drain lines regularly.  

 

Clean the lamps regularly for maximum lighting efficiency.  

 

Clean the internal walls regularly for maximum reflectance.  

 

On air-cooled, self-contained chambers inspect to ensure the air-cooled condenser fins 
are free of dust and debris, use a fine brush and vacuum to clean the fins or use 
nitrogen or compressed air to clean the fins. 

 

Avoid using high-pressure washers or high-pressure gases as this could cause damage 
to the aluminum fins. Use maximum pressure 60 psi (4.14 bar). 

 

 

 

Electrical power remains at the main terminals. Use extreme caution during 
maintenance procedures to prevent injury. 
Controller may come equipped with an optional Uninterrupted Power Supply (UPS) 
such that power will remain live for a period of time even if the main power supply is 
disrupted or turned OFF. 
Use extreme caution to prevent injury. If your unit comes equipped with a UPS, it will 
be located inside the control panel. 

DO NOT service the control panel without using proper ESD procedures, including the 
use of a grounding strap and/or anti-static mat. 

Use only original replacement parts when maintaining and servicing the equipment.
