INSTALLATION & MAINTENANCE INSTRUCTIONS
Series 342 Stainless Steel Filter Regulator (Compact) size: 1/4"
corresponds to the product's classification.
Check Nameplate for correct catalog number,
pressure, temperature and service. Never apply
incompatible fluids or exceed pressure rating of the
regulator.
The installer must install the air filter regulator at the
user's location in accordance with the requirements
specified in Directive 99/92/EC.
POSITIONING
d For optimum life and performance, the FR should be mounted
vertically upright (Max. Inclination 5°).
PIPING
Connect piping to valve according to markings on FR
body. Apply pipe compound sparingly to male pipe
threads only. If applied to FR threads, the compound
may enter the FR and cause functional difficulty. Avoid
pipe strain by properly supporting and aligning piping.
When tightening the pipe, do not use the FR as a lever.
Locate wrenches applied to piping as close as possible
to connection point. Direct Frontal mounting or mounting
with brackets possible.
MAINTENANCE
NOTE: Ensure the air supply is completely stopped. It
is not necessary to remove the FR from the pipeline
for repairs.
CLEANING
All FRs should be cleaned periodically. The time between
cleanings will vary depending on the medium and service
conditions. The most common part that requires cleaning
is the filter element.
Use running water for regular cleaning or a mild
detergent for cleaning the filter element. Do not use
diluted acids, strong detergents or corrosive chemicals.
For auto drain version clean the filter ring periodically
CAUSES OF IMPROPER OPERATION
Incorrect pressure: Check upstream pressure.
Pressure to FR must be within range specified on
nameplate.
Excessive Leakage: Disassemble FR and clean
all parts. If parts are worn or damaged, install a
complete ASCO Spare Parts kit.
MANUAL DRAIN OPERATION
Hold the knurling face of drain with fingers & rotate
it to the anti clockwise direction looking from top to
unscrew the manual drain to purge out the water that
accumulated in the bowl. After draining out, screw the
manual drain back to its original position & ensure proper
working of AFR.
AUTOMATIC DRAINING
ASCO SS-AFR auto drain provides hassle free draining
of equipment which purge out the water accumulated in
the bowl automatically. Flexible tube (Barb connection)/
Hard piping (Adapter1/8"NPT-optional) can be used for
collecting the condensate. It also provides manual drain
feature integrated with automatic drain. Use spanner to
operate the same with the flat provided on it.

VALVE DISASSEMBLY
1. Disassemble valve in an orderly fashion using
exploded views for identification and placement of
parts. Refer to Figure 1.
2. Remove bowl by unscrewing the fasteners and the
bowl seal.
3. Unscrew the filter sub-assembly by hand itself.
4. For normal maintenance (cleaning) it is not
necessary to remove the valve seat. However, if
valve seat removal is required, just pull it out of the
body.
5. Remove the manual drain/auto drain from the bowl.
6. Remove bonnet screws, valve bonnet, top springs
and diaphragm assembly.
7. All parts are now accessible to clean or replacement.
If parts are worn or damaged, install a complete
ASCO Spare Parts kit.
d Use Metal Pipes only for IN and OUT connection. For Non
– Metallic / Non – conductive pipes requires EARTHING OR
GROUNDING that can be given in any one of front side M5 mounting
hole shown as
in the assembly drawing on page 2
-- Service Notice--
When installing a new ASCO Spare Parts kit, the
parts supplied are shown in Figure 1. The parts
supplied are new and a direct replacement for the
present parts provided all new parts are installed.

VALVE REASSEMBLY
1. Lubricate all gaskets with MOLYKOTE
111 lubricant
®
or an equivalent low temperature silicone fluid.
2. Add a layer of NEVERSEEZ NS-160 on all screw
threads.
3. If removed, install poppet valve seat in body. Apply a
small amount of NEVERSEEZ NS-160 to Filter sub
assembly threads. Hand tight the assembly as far as

d WARNING! To prevent the possibility of personal injury
or property damage, ensure below mentioned testing has been
completed before returning to service of FR. Perform internal seat
and external leakage tests with a nonhazardous, noncombustible
fluid. Wrong assembly will invalidate the approval. In case of
replacement of parts by the user, the traceability of the final
product cannot be guaranteed by ASCO and must be ensured
by the user.
5. Restore line pressure to FR.
6. After maintenance is completed, operate the FR
a few times to be sure of proper operation and
installation.
