Attach Blowers
Connect an air blower to the air blower port on the transceiver using the air
hoses and clamps. Connect the other air blower to the air blower port on the
retro reflector using the air hoses and clamps. See Figure 2-6 for the air
blower port location.
Mounting the
Transceiver and Retro
Reflector
Install the transceiver and retro reflector according to the following procedure.
This installation procedure applies to both the transceiver and the retro
reflector. Installation dimensions and clearances are shown in Figure 2-1.
1. Power up the air-purge blowers to prevent stack particulate from
accumulating in the nipple and air-purge housing.
2. Attach the transceiver and retro reflector to the air plenum assembly by
placing them on the hinge pins (Figure 2-7).
3. Close transceiver and retro reflector and secure in place with the two
hold-down latches.
Figure 2-7. Upper and Lower
Hinge Pins
If installed location has a positive pressure the air-purge system must be used continuously
during installation to prevent process gases from contaminating optical surfaces or over
heating instrument electronics. If the system is shut off for more than momentary
interruptions, the instrument may be damaged. Failure to provide continuous air-purge may
void the warranty.
