INSTRUCTIONS

This oven has been designed to operate at class 100 standards. It is not shipped

clean room ready and the instructions below must be followed for proper

installation. See Figure 2

6.1 BURN-IN OF THE HEPA FILTER

Before using this oven, it is important that the filter be burnt-in properly.

During burn-in, the Hepa filter will off gas. Because of this the intake and

exhaust ports must be open, with the exhaust ports being ducted outside.

A material safety data sheet is included with your operation literature for

reference. Note that you should read Section 7.0 and have a clear

understanding of how to operate the unit prior to following this procedure.

A. To burn in filter:

1. Set oven at: 125°C for 1 hour;

150°C for 4 hours;

175°C for 1 hour;

200°C for 1 hour.

2. If operating temperature is higher than 200°C, continue the

cycle of one hour at 25° increments until the operating

temperature is achieved.

B. After burn-in, the interior must be disassembled and cleaned.

Make sure unit is unplugged and cooled down before disassembly.

When disassembling, use an 8/32 nut driver for removing all the

cap nuts. Remove the bottom liner insert before removing the liner

side inserts. Do not remove the Hepa filter cover. After burn-in, the

filter is very delicate (like the mantel of a lantern) and will fall apart.

The casing should only be removed when replacing the filter.

6.2 CONTROL AREA EXHAUST

As part of this design the control compartment is sealed and requires a

minimum of 30 CFM (Cubic Feet Per Minute) to be drawn from the control

compartment exhaust port. This is required to limit the control
