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 circumstance 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 these limits. 

3.1 

Power Source:  

Check the data plate for voltage and ampere requirements before making a connection. 

If  the  requirements  match  your  power  source,  plug  the  power  cord  into  a  grounded  outlet.  VOLTAGE 
SHOULD  NOT  VARY  MORE  THAN  10%  FROM  THE  DATA  PLATE  RATING.  These  units are intended 
for  a  50/60  Hz  application.    We  recommend  a  separate  circuit  to  prevent  loss  of  product  due  to 
overloading or circuit failure. 

Electrical supply to the unit must conform to all national and local electrical codes.  

3.2

 

Location:   

When  selecting  a  site  for  the  incubator,  consider  all  conditions  that  may  affect 

performance, such  as  extreme  heat from  radiators,  stoves, ovens, autoclaves, etc.  Position the 
unit  so  the  end-user  has  access  to  the  power  plug.    Avoid  direct  sun,  fast  moving  air  currents, 
heating and cooling ducts, and high traffic areas.  To ensure air circulation around the unit, allow a 
minimum  of  30  cm  (11  13/16

”)  between  incubator  and  any  walls  or  partitions  that  may  obstruct 

free airflow and a minimum of 10 cm (4”) top clearance. 

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  lifting  or  stabilization.  The  unit  should  be 
completely restrained from tipping during lifting or 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.  Leveling feet (supplied) are to be installed in the holes 

at  the  base  of  the  oven.  Turn  them  counterclockwise  to  raise  the  level  and  clockwise  to  lower  the 
level.  If the unit must be moved, turn the leveling feet in all the way to prevent damage.   

3.5 

Cleaning:

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

if  assembled  and  clean  the  inside of the chamber thoroughly with a  disinfectant that is suitable for 
your application.  Make sure to rinse the cleaned surface with a damp cloth, using water only, and 
dry the surfaces with a clean cloth. DO NOT USE chlorine-based bleaches or abrasives as they will 
damage the stainless steel surface. 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  the  coatings.  A 
similar 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 form the electrical service when cleaning and assure all 
volatile  or  flammable  cleaners  are  evaporated  and  dry  before  reattaching  the  unit  to  the  power 
supply. 

3.6 

Burning  In:   

It is recommended that the unit go through a “burning in” process prior to operation.

 

This  is  to  eliminate  the  smoking  of  protective  coatings  on  the  element.    Read  sections  4,  5  and  6 
carefully  to  understand  operating  requirements.    To  burn  in  turn  the  Overtemperature  Safety  to 
maximum and set the digital display to 200.  Run for a minimum of one hour under ventilation until 
smoke dissipates.
