Equipment Placement.
Make sure the instrument
is placed on a firm, level table in an area with
adequate ventilation or in a hood. The unit may be
leveled by making minor turning adjustments to
the feet located at the base of the unit. Please
note that Koehler does not supply a level with this
equipment.
Environmental Conditions:
The instrument
environment must comply with the following
conditions for proper setup:
No / Low Dust
No direct sunlight
Not near heating or AC ventilation ducts
No Vibrations
Clearance from other instruments
Temperature Range: 5 to 40°C
Elevation to 2000 meters
Relative Humidity: < 80%
Ventilation.
A fume hood or exhaust system is
required for expending any fumes or vapors that
have been generated while operating the unit.
Flammable vapors and/or steam are generated
during operation and must not be permitted to
accumulate. A canopy-style hood may be used if
the height from the top of the unit to the canopy is
5 feet or less. The exhaust blower should have a
rating of 1000 C.F.M. or greater.
NOTE:
Adjust the exhaust blower rate so
that it removes generated vapors / steam,
however be sure that the exhaust system does not
create a draft large enough to remove vapors from
the test cup area or blow out the test flame as this
will affect results of the test.
Gas Supply.
Connect the gas inlet to a regulated
low pressure gas supply (0.5 to 1.0 psi). Use only
propane, LPG,
or
natural gas
. Do not use direct
unregulated pressure from an
LPG
tank.
NOTE:
Be sure Flame Control Switch
(Figure 1, Item 3) is in the OFF position when Test
Flame Applicator is not in use.
Power.
Connect the line cords to properly fused
and grounded receptacles with the correct voltage
as indicated in section 1.3 or on the back of the
unit.
WARNING:
For safety, disconnect the
power when performing any maintenance and/or
cleaning..
