Isotemp vacuum oven

Our company just purchased Fisher Scientific Isotemp Vacuum Oven Model #: 282A. We will have to perform our own IOQ.

looking for any tips on performing IOQ for the oven.

Is there any unique requirement for the Vacuum capabilities?

Since it is 23"L x 26"W x 22"H, would only 10 TCs (8 for each corner, 1 center, and 1 near RTD) be required? Please advise

I assume for OQ, a empty thermal mapping is the only requirement for thermal mapping?

Thanks in advance.
