3 Description
3.1 The Need for Air Purging
In order to ensure that the optical system remains clean, air must be supplied
continuously through the purge unit. Though negative pressure within a stack
may draw sufcient air through the air purge nozzle to prevent a build up of dust
and fumes, a positive pressure air supply is recommended in all installations.
Air blowers supply ltered air to protect the optical surfaces from dirt and
overheating. Optional pressure switches may be tted to indicate insufcient air
ow.
3.2 Blower unit configuration
The standard conguration of the plate-mounted blower (illustrated), comprises a
stainless steel baseplate tted with:
• Air Filter Unit
• Rain Cap (tted onto Air Filter)
• Blower Motor (as ordered)
• Interconnecting hoses
• Standard adaptor

3.4 Description - Blower Options
Y-piece
This optional Y-piece adaptor is used where a single blow
is capable of supplying sufcient air to both sides of the
instrument. The adaptor splits the blower air supply output
into two equal parts. The Y-piece adaptor is customer tted at
site. Refer to tting instructions in Section 6.
Air Pre-filter
This optional air pre-lter is used where the ambient air
(which is the source of air for the blower) has high levels of
dust or dirt particles and is too low quality for use with the
blower. The air pre-lter is customer tted at site. Refer to
tting instructions in Section 7.
Pressure Switch
This optional Pressure Switch provides a warning
indication if the purge air ow rate falls below the
recommended minimum. This would normally
indicate a lter blockage, a pipe blockage or a
power failure to the blower motor. Remedial action
should be taken when such a condition occurs.
Select the appropriate switch for single blower or
dual blower installations. (See Appendix 2)
The pressure switch assembly is customer tted
at site. Refer to tting instructions in Section 5.
Wiring instructions for connection to various LAND
instruments are given in Appendix 1.
Safety Filter
The Safety Filter is used to provide additional
protection for the optical system. The safety lter
is tted in addition to the standard air lter. The
safety lter will quickly block up if the normal
lter element is damaged and allows dust to pass
through. The resulting drop in air ow rate will
activate the pressure switch (if tted).
Refer to tting instructions in Section 8.

Weatherproof Cover
The blower unit is environmentally rated to IP 55 /
NEMA 4. Where further protection is required, up to IP
55 / NEMA 4X, then the optional Weatherproof cover
should be used and tted to the blower assembly. The
Weatherproof cover is customer tted at site. Refer to
tting instructions in Section 9.

4.1 Installation Guidelines
Surface Temperatures
Surface temperatures of the motor can reach 100 °C / 212 °F. If there is
a possibility of the accidentally touching the motor surface in the intend-
ed location, the weatherproof cover or some other guard must be tted.
Air Quality
Use only in locations where the incoming air is not corrosive, inammable or
explosive.
Rating Plate
The rating plate must be in a readable position.
Supply Requirements
For electrical supply, refer to rating plate tted to the blower motor itself.
The recommended circuit breaker (See Section 10) must be tted close to the
blower and marked for the purpose.
Air Hose lengths
If two blower units are used, these should be positioned so as to keep the air
hoses as short as practical.
If one blower unit is used, installation midway between the instruments is
recommended. In any case, equal lengths of hose must be used to connect the
blower to the two parts of the instrument.
Air Quality Requirements
CAUTION
The air temperature at the intake point must not exceed 50°C
(122°F).
The air blower intake must be at a point where the least dust,
oil or moisture accumulates.

4.2 Installation
The mountings for the air blower should be marked out in the xing position.
1) Fit the plate mounted blower to the mounting position using suitable bolts.
There are six holes available for attaching the baseplate to a at, vertical
surface. Ensure the blower is rmly secured. Refer to Installation Drawings.
770-073 DRG1 Plate-Mounted Blower Unit - Standard Assembly
770-073 DRG2 Plate-Mounted Blower Unit - Optional Accessories
It is recommended to use bolts and NOT studs as these would prevent
tting of the weatherproof cover.
2) Make the electrical connections. Refer to Sections 6-3, 6-4 and Appendix 1.

3) Check that the fan motor is running in the correct direction. The running
direction is shown on the motor and the direction of ow on the pump
housing by arrows.
CAUTION
Running the blower in the wrong direction will cause hot gases
to be sucked into the optical unit and ultimately inside the blow-
er unit. Prolonged mis-operation may result in complete unit
failure. Turn off immediately and do not use. Contact LAND for
advice
4) If the units are not to be installed immediately, protect the open ends of the
hoses against moisture.
CAUTION
Where ue gas ducts are already in use, the fans must be
switched on and the air hoses pushed on to the connection noz-
zles before tting the instruments.
Use the hose clamps supplied to secure the air hoses.

7 How to fit an Air Pre-filter
Where the ambient air quality around the blower unit contains high levels of dust
or ash, then it is recommended to t an air pre-lter.
Fitting Procedure
1) It is necessary to remove the rain cap before tting the pre-lter.
2) Loosen the clip connector around the rain cap and pull upwards until the cap
is free. The cap is no longer required.
3) Push the air pre-lter onto the pipe and secure using the clip connector.
4) Fitting is now complete.
