INSTALLATION

 

Local city, county, or other ordinances may govern the use of this equipment.  If you have any questions about 
local  requirements,  please  contact  the  appropriate  local  agency.    Installation  may  be  performed  by  the  end 
user.  

Under normal circumstances this unit is intended for use indoors, at room temperatures between 5

 and 40

C, 

at no greater than 80% Relative Humidity ( at 25

C) and with a supply voltage that does not vary by more than 

10%.  Customer service should be contacted for operating conditions outside of these limits. 

3.1 

Power:

 The power source must match the voltage, cycle, phase and ampere requirements listed on 

the data plate (located just above the power cord on the back side of the oven).  The unit is intended 
for  50/60  HZ  application.  Make  sure  your  power  supply  matches  that  shown  on  the  data  plate. 
VOLTAGE SHOULD NOT VARY MORE THAN 10% FROM THE DATA PLATE RATING.  A separate 
circuit is recommended to preclude loss of product due to overloading or circuit failure.  Note that the 
electrical supply to the unit must conform to all national and local electrical codes. 

3.2 

Location:

 When selecting a site for the oven, consider conditions that may affect performance, such 

as heat or cold from air vents, fast moving air currents, other ovens, autoclaves, direct sun, etc.  Avoid 
high traffic areas that may reduce accessibility to the oven and allow at least  20cm between the unit 
and surrounding walls or partitions that might obstruct free airflow. 

3.3 

Lifting/Handling:

 These units are heavy and care should be taken to use appropriate lifting devices 

that  are  sufficiently  rated  for  these  loads.    Units  should  only  be  lifted  from  their  bottom  surfaces.  
Doors, handles, and knobs are not adequate for lifting or stabilization.  The unit should be completely 
restrained from tipping during lifting and transport.  All moving parts, such as shelves and trays should 
be  removed  and  doors  need  to  be  positively  locked  in  the  closed  position  during  transfer  to  prevent 
shifting and damage. 

3.4 

Leveling: 

The unit must sit level and solidly.  The oven is equipped with non-adjustable rubber feet to 

raise  it  off  the  counter  and  prevent  sliding;  however,  the  counter  must  be  level  to  provide  optimum 
working and safety conditions. 

3.5 

Cleaning:

  The oven was cleaned at the factory, but not sterilized.  Remove all interior parts, including 

shelves  and  shelf  clips.    If  assembled  and  clean  the  inside  of  the  chamber  thoroughly  with  a 
disinfectant that is appropriate for your application. DO NOT USE chlorine-based bleaches or abrasive 
cleaners,  as  they  will  damage  the  ovens  interior  surfaces.    DO  NOT  USE  spray  cleaners  that  might 
leak  through  openings  and  cracks  and  get  on  electrical  parts  or  that  may  contain  solvents  that  will 
harm coatings.  A regular periodic cleaning is recommended. 

WARNING: 

Never  clean  the  unit  with  alcohol  or  flammable  cleaners  with  the  unit  connected  to  the 

electrical supply.  Always disconnect the unit from the electrical service when cleaning and assure all 
volatile or flammable cleaners are evaporated and dry before reattaching the unit to the power supply.
