Oven Components
Set Up
STEP 1: Remove protective covering(s).
STEP 2: Position unit for use.
Position the vacuum oven on the oor or
a work surface strong enough to carry the
oven’s weight.
Model Weight
BOV-20 60 KG / 132 LBS
BOV-50 95 KG / 210 LBS
BOV-90 145 KG / 320 LBS
Additionally, the oven requires a minimum
clearance area as shown in the diagram (left).
STEP 2a: Lock the front casters. (BOV-90 only)
Using your foot, press down on the caster’s pedal to lock the oven in place.
Lift up on the bottom of the pedal to unlock the caster to reposition or move
the oven.
STEP 3: Relieve oven chamber vacuum.
Rotate the balance hole 180Oto relieve the vacuum applied at the
factory prior to shipping. Upon relieving the applied vacuum, close
the balance hole.
STEP 4: Unlock and open door. Remove
supplied accessories.
STEP 5: Push hose onto KF-25 hose barb
and your vacuum pump or cold trap tting.
STEP 6: Assemble the KF-25 hose barb, seal
ring, and clamp to the oven’s KF-25 ange.
Attach your tting to your vacuum pump or
cold trap.
STEP 8: Plug your vacuum pump electrical
cord into the outlet on the oven and turn
the vacuum pump on. (BOV-20 & BOV-50)
For BOV-90 plug vacuum pump into nearest
electrical outlet.
STEP 7: Attach your inert gas or air hose to
the oven’s air inlet hose barb.
STEP 9: Plug the oven’s electrical cord into
appropriate outlet.
Rotate the door handle counterclockwise 90O
to unlock the door and carefully pull the
door open. Remove the supplied accessories
and shelves. Remove protective shelf covering.
If the door does not move easily, DO NOT TUG on the door.
Doing so can damage the door seal. Use your nger or a at
blade (standard) screwdriver to ick the door seal to release
the seal from the glass door.
Review the vacuum pump specications to ensure it is a
two-stage pump and has the following ow rate capacity.
BOV-20 and BOV-50: 2 liters/second (4 CFM)
BOV-90: 4 liters/second (8 CFM)
Drawing Vacuum
STEP 1: Close and lock door.
STEP 2: Ensure balance hole is closed.
STEP 4: Turn the PUMP switch on.
Rotate the PUMP switch clockwise 90O.
Vacuum pump will instantaneously turn on,
solenoid valve will open, and vacuum will be
applied to the chamber.
It will take approximately 3-4 minutes to reach
-14.7 PSI / -1 bar. Use the balance hole to lengthen
the time to reach maximum applied vacuum.
Remove the black cap from the hose barb tting.
Option 1: Leave the barb tting bare
Option 2: Push a 3/8”ID hose onto barb tting. Attach other end of hose to
your inert gas or air supply, or if neccessary, attach the hose to a cold trap.
Lift the outlet cover. Push
the vacuum pump’s power
cord into the 120 VAC, 5
Amp rated receptacle. Turn
the vacuum pump’s power
switch on.
After placing specimens on the oven
shelves, close the door and turn the door
handle clockwise 90O.
The balance hole arrow must point
between 2 and 10 o’clock for the
balance hole to be fully closed.
Use the balance hole to control
vacuum draw speed.
It must be fully closed to reach a
-14.7 PSI / -1 bar.
BOV-20 & BOV-50
STEP 4: Turn your vacuum pump on.
Rotate the PUMP switch clockwise 90O.
Solenoid valve will open and vacuum will be
applied to the chamber.
It will take approximately 3-4 minutes to reach
-14.7 PSI / -1 bar. Use the balance hole to lengthen
the time to reach maximum applied vacuum.
BOV-90
STEP 5: Turn the PUMP switch on.
It is not required to draw a vacuum to apply heat to the
specimens in the oven. However, applying a vacuum rst
will reduce the humidity in the oven and increase the speed
to reach desired temperature.
STEP 3: Turn on unit power
Push the circuit breaker’s lever
down to turn on the power to
the oven.
