LF-210 Manual P/N 24154 4 April, 2003
AIR SYSTEM DESIGN
Filter-regulators are
available in a variety of
sizes and types. Their
purpose is to remove
water, oil and other
foreign matter from the air
line and to maintain a
constant pressure of 60-65
PSI at the toilet. The
following steps must be
observed to assure moisture will be removed from
the airline:
1. Drain air compressor receiver regularly. Most
water tends to accumulate at this point.
2. Install drip legs with condensate drains at all
low points in air piping.
3. Whenever possible, grade all airlines back to air
receiver or drip leg assembly and drain
regularly.
4. The air supply to the toilet must be taken from
the top of the main or branch air line.
AIR COM PRESSOR
Be certain compressor crankcase has proper oil
levels. Locate the compressor in a clean, dry, well
ventilated location. Size compressor according to
Air Compressor Spec, Form 273.
INSTALLATION PROCEDURE
Read Installation
Procedures completely
regarding all
installation/start up points
prior to installation.
PRELIM INARY PROCEDURE
Remove toilet from box carefully. Install toilet seat
and flush handle before mounting toilet to floor.
Seat is not included with vitreous china models. Air
connecting kit (P/N 93086), bolt caps and closet
screws are provided with all vitreous china models.
AIR CONNECTION
Install a filter-regulator
assembly in airline. Place
the filter-regulator as close
as possible to the first
toilet and in an accessible
location. The plastic
airline (provided) from the
air source connects to the toilet at the flush
activator. On models where the flush handle is
mounted on the side of the toilet, the plastic air line
enters the toilet through the back wall or up through
the floor under the back of the toilet. Install air
shut-off valve at toilet. Fitting on toilet is 1/4"
compression fitting. Do not over-tighten fittings on
toilet. Blow any debris from airline prior to
connecting to toilet.
Regulate air pressure to 60-65 PSI constant at
the toilet for proper operation.
Where an air main is required, such as a 1/2" copper
line, the air line to the toilet should be connected to
the top of the main airline to prevent condensation
reaching the toilet.
WATER CONNECTION
Install water shut-off valve (angle
stop) at 9" off center line and 3"
above floor (see Rough-In
Dimensions). Water supply line
should be 1/2" flexible line. Fitting
on toilet is ½" NPT slip joint nut
(1/2" lavatory supply). Connect
flexible water supply line to toilet
first, then connect to angle stop.
CAUTION: Water supply connector is made of
nylon. Be careful not to cross
threads.
Water pressure must be regulated at an even
pressure between 20 to 50 PSI at the toilet for it
to operate properly.

LF-210 Manual P/N 24154 5 April, 2003
DRAIN CONNECTION
- See Rough-In Dimensions
Bottom Discharge Models: Center on floor flange
12" (standard) from finished wall with wax ring
(provided). If floor is uneven a second standard wax
ring may be added. If bottom ring of toilet hits
flange, it should be ground down for added
clearance, as any contact will break seal on hopper.
Rest toilet on its back on a padded surface (e.g.
packing from shipping box). Center wax ring on
toilet discharge flange. Turn toilet over, lifting up,
and center the horn of the wax ring into the toilet
floor flange. Compress the wax ring by applying
weight to the toilet.
REAR DISCHARGE MODELS: Discharge line
should be connections at hopper with a No-Hub
Coupling (P/N 33324, provided). Do not glue or
connect fittings until fitting alignment has been
checked. Toilet discharge line must have a rise
(trap) (see ROUGH-IN DIMENSIONS) in order to
provided water trap seal when flapper is open.
CAUTION: do not apply stress to align outlet to
waste line. This will result in eventual seal damage.
DOWNWARD DISCHARGE MODELS: Toilet
mounts to floor with 1/4" closet bolts. Install screws
with a 3/8" nut driver. Screw on bolt caps to
mounting screws.
INSTALLATION AND START UP
1. Position and mount
the Toilet to floor.
See Rough-In
Dimensions.
2. For units with

USAGE LUBRICATE
Light Every 5 years
Medium Every 2-3 years
Heavy Every year
ROUTIN E M AIN TENAN CE
Your Microflush toilet
has an air-operated
Air/Water Sequence
Valve which requires
periodic lubrication
with a silicone based
lubricant.
CLEANING
Use Micro-Clean Organic Spray Cleaner, P/N
24542. Caustic drain openers or non-biodegradable
cleaners should not be used if the toilet is connected
to a septic tank or Microphor biological sewage
treatment system. Clean as follows:
1. While depressing the flush activator, turn OFF
the water. Allow the bowl cleaner to flow into
the lower chamber. Keep the flushing activator
depressed.
2. Insert bowl brush into lower chamber and agitate
mixture.
3. Remove the bowl brush and release the flush
activator.
4. Turn the water ON and flush twice to rinse
thoroughly.
WINTERIZING
(out-of-service winter storage)
Shut OFF water to toilet. Flush toilet three times or
until water no longer flows into the bowl. Unhook
water supply at angle stop. Empty water in line into
receptacle. Shut OFF air supply to the toilet. The
unit is now prepared for freezing temperatures.
OPEN petcocks on drip legs and air receiver drain
after shutting down air compressor and isolating
airlines.
Pipe will protect flapper seal. If valve will not
operate with water off, hold flush lever down and
turn water on and off quickly to free valve action.
When the passage becomes clear, turn on the water
and press flush handle to start the flush cycle.
CLEANING BLEED-OFF PLUG
ASSEM BLY
Standard Flush:
Remove plug and clean with solvent; air blow dry.
Positive Flush:
Remove plug and clean with solvent; air blow dry;
remove and clean plug on Detent Valve.
Note: Use 5/32" or 4mm Allen wrench to remove
plugs.
CLEARING THE TOILET
If the toilet becomes plugged, shut off the water
supply, press the flush handle and hold. Flapper in
the bottom of the toilet will remain open until flush
handle is released. Check to see if the restriction
can be removed from lower portion of toilet with a
hooked wire, being careful not to damage the rubber
seal on the flapper or the mating surface on the
hopper. If obstruction can not be picked out with a
hook or tongs, use plunger by pushing in slowly and
pulling out quickly to pull object back into the
hopper. If necessary, turn air off and use a snake
inserted into a short plastic pipe placed in hopper.
Note: Bleed-off plugs on Air & Water Sequence
Valves and Detent Valves are different sizes that are
not interchangeable.

LF-210 Manual P/N 24154 7 April, 2003
TROUBLESHOOTING
Your Microflush®toilet is designed to give you years of trouble-free operation. Please check the following
before beginning any service or repair:
Water supply: 1 Is the water turned on?
2 Is the water pressure between 20 and 50 psi at the toilet for pressure water system?
3 Is there 6 feet minimum of head for gravity systems?
Fluctuating or high water pressure can cause intermittent problems with the toilet operation.
Check the water pressure at different times of the day (i.e., early morning, noon, evening) to
determine if you have fluctuating or high water pressure. A pressure-reducing valve installed on
the incoming water line will assure you have even pressure. Make sure no check valve is
installed before the Air/Water Sequence Valve.
Air system: 1 Is the air turned on?
2 Is the air pressure set at a constant 60-65 psi at the toilet?
3 Do you have any air leaks or kinks in the air system?
4Do you have water in the air system? This usually causes irregular timing.
Drain the compressor tank and check the filter regulator and drip leg(s) for water. To check for
water in Air/Water Seq. Valve, remove Bleed-Off Plug, put finger over screw opening and flush.
If water is present, it will squirt out. If water is detected, then the air cylinder and airlines must
also be drained.
Cycle time: 1 Is the flapper cycle time set correctly at 4-8 seconds?
2 Is the Bleed-Off Assembly plug blocked? (See page 6)

FLUSH ACTIVATORS
95054 - Commercial Flush Activator
95557 - Palm Button Conversion Kit
95002 - Residential Flush Activator

LF-210 Manual P/N 24154 13 April, 2003
POSITIV E FLUSH ACTIVATOR (Commercial) Remote, P/ N 95087
The Detented Positive Flush Activator has been added (as an option) to our product line. It was developed in
order to overcome the necessity for the toilet user to hold the standard flush actuator in the deflected position for
a definite time (about 2 1/2 seconds) to insure full actuation of the toilet flush cycle. This option is
recommended for high use, public facilities.
It's principle of operation is as follows:
A) Under user control, a two way valve, requiring no more than 1/32" deflection for full flow, pilots a piston
drive detented mechanism.
B) The detent force is overcome after air pressure over the piston rises to 40 psi thus driving the standard flush
actuator to the full flush position.
C) The detent is reset after the entrapped air over the piston is bled to atmosphere. The bleed rate (and thus the
length of time the flush actuator is held in the flush mode) is controlled by the head bleed plug with a fixed
orifice size.

LF-210 Manual P/N 24154 14 April, 2003
AIR WATER SEQUENCE VALVE LUBRICATION
1. Disassemble valve from bottom to top by first unscrewing the Bottom Cap from the Main Body. Then, to
unthread the piston from the spool, insert a 3/16" hex into the hex opening at top of spool. Use an adjustable
end wrench on the oblong boss on bottom of piston to unscrew piston from spool and push spool up through
valve body to remove. Remove Top Cap and Water Seal. You will need a pair of needle nose pliers to
remove the Nut and Stem from the Bottom Cap.
2. Replace parts indicated in BOLD supplied with kit. Lubricate all O-Rings with lubricant provided. A light,
complete coating is all that is required as over lubrication will clog air passages.
3. Re-assemble valve from top to bottom as shown, with the exception of the Top Cap and Water Seal which go
on last. Make sure to align the yellow timing marks on Bottom Cap, Main Body and Water Body.
4. If desired, this valve may be returned to the factory for rebuilding and lubrication.
