Upon start-up all Quincy Lab Bench Ovens will display the current 

chamaber temperature (green LEDs) and begin the heating process to 

the factory default temperature set-point (orange LEDs) which varies 

depending on your oven’s model.  

To change the factory default set temperature simply do the following:

Turn  the  power/recirc.  fan  switch  to  the  up  position.  

  

The blower will begin to circulate chamber air and the temperature controller will power ON. 

Turn heater switch to the up position (heat).

Units heat elements will activate and begin heating. 

If heater switch is not in the ON position the unit will not heat.

     

Digital Controller Set-point Temperature. 

The controller will begin its normal process to reach the factory default temperature set-point. The heat cycle indicator 

light on the controller will activate and cycle on and off with the heaters to reach and maintain the set temperature. 

Each  shelf  will  support a distributed  load  of  100  lbs.  maximum. 

Do not exceed a combined total of 300 lbs. within the oven at one 

time. Avoid placing articles on the oven floor. Instead, use  a shelf 

at the lowest adjustable position.

Install adjustable shelf by first placing the shelf bracket rivets into the 

corresponding keyhole supports located on each inner side of the oven.  

Orientate the bracket in the "down" or " L" position. This position guides 

the shelf in and out and protects the side wall from being scratched.The 

bracket may also be placed in the "up"  or "      " position if slightly more 

interior clearance is needed.  Place the shelf on the brackets as shown.  

(FIG. 3)

Care should be taken when removing articles from the oven.    

Don't  pull  the  shelf  out  when  removing  heavy  loads. 

The  shelf  

is  not  secured  and loads can tip and fall forward.

All control parameters and other control variables have already been factory set for your model's temperature range and 

capacity to provide heating and performance characteristics for a broad range of applications.  Your Bench Series ER oven 

is ready for operation.

Typically,  the  oven  will  need  to  cycle  at  the  set  temperature  for  a  minimum  of  20  minutes  before  it  will  

achieve  equilibrium  and  becomes  stable

  (see  stability  specs. on page 1).
