Aligning the probe bracket and chamber thermocouple
IMPoRTANT NoTe:
Aligning the probe bracket is critical to the correct functioning of the

unit. It is strongly recommended that the probe bracket alignment jig is used when
performing this operation
.
To align the probe bracket assembly, proceed as follows (see Figure 5):
1. Be sure that the four cap screws with flat washers (23) are loose enough to allow adjustment of
the probe bracket, but there is sufficient friction between the bracket and the armature so that
the probe bracket cannot move under its own weight.
2.
a.
If using the probe alignment jig:
1. Insert the jig into the armature until it just touches the probe tips.
2. Gently push the jig towards the probe bracket while at the same time adjusting the
probe bracket until the probe tips enter the openings in the end of the alignment rods
of the jig. PERFORM THIS OPERATION WITH CARE. DO NOT BEND THE TIP OF THE
CHAMBER THERMOCOUPLE.
3. Rotate the alignment rods and at the same time finely adjust the position of the probe
bracket until the rods rotate, and slide in and out freely.
4. Using the Allen key, tighten the four cap screws with flat washers in the following
tightening pattern: upper left hand corner, bottom right hand corner, upper right hand
corner and the bottom left hand corner.
5. Recheck the alignment rods to ensure that they still rotate and slide in and out freely.
Slacken off the screws and repeat the procedure if necessary if the alignment rods are
tight.
