Fill-Rite TS06 LPG Precision Meter - Manual (Page 13)

 Inspect the slide valve. Remove and build–up of salts or
dirt which may cause the valve to stick. The valve
should slide freely without any signs of sticking. There
should be no scratches or burrs on the valve assembly.
Replace if there are signs of damage.
 Inspect all seals, and replace if damaged or brittle.
 Re-assemble the meter in the opposite direction making
sure all bolts are torqued to the proper specifications.
Differential Valve Service (see page 11):
 Remove the outlet piping flange.
 Remove the connecting tube between the differential
valve and the vapor eliminator.
 Remove the Screws (1) securing the cover (2) from the
valve body (4).
 Remove the differential valve piston assembly (8) and
spring (7).
 Inspect the valve body and cover for damage. Clean all
surfaces of dirt or deposits using a fine (200 grit) emery
cloth if necessary. If damage is more than superficial,
replace the valve.
 Inspect all seals and replace any brittle or damaged
seals. It is recommended that all seals be replaced
during service.
 Replace the U-Cup seals (8a). Note proper position of
the seals. Use a small amount of Teflon lubricant to
help install the seals.
 Replace the square cut seal (8b). Use thread sealer
(Locktite Blue) when installing the fastener (7e).
 Re-assemble the valve in the opposite manner.

Inlet Check Valve Service: (Optional component)
 Disconnect the outlet piping from the meter assembly at
the differential valve outlet flange.
 Remove the meter as detailed in the METER DISAS-
SEMBLY section.
 Remove the back check valve assembly (11).
 Manually open and close the valve to assure proper
operations.
 Inspect for dirt of salt build-up and clean if necessary.
 Inspect the seals for wear or damage. Replace worn or
brittle seals.
 Reassemble the valve and install in the strainer hous-
ing. This valve is optional and will not retrofit into strain-
er housing not originally supplied with the valve.
 Reassemble the system making sure bolts are torqued
to the proper specifications
Strainer Service: (See page 8)

Remove the four bolts (37) from the rear cover and re-
move the cover (7).
 Inspect the seal (12) and replace if damaged or brittle
 Remove the strainer (10). Clean the strainer with low
pressure air, blowing out all loose sediment. Wash the
strainer with solvent.
 Inspect the strainer for holes or other damage and re-
place if necessary.
 Re-assemble making sure the bolts are torqued to the
proper specifications.
Vapor Eliminator Service: (See pages 8 & 11)
 Disconnect the vapor return line flange and the differen-
tial valve tubing.
 Remove the five bolts (3) from the vapor eliminator
housing.
 Remove the cover (4) from the vapor eliminator hous-
ing.
 Remove the float and valve assembly (34) from the
cover for inspection.
 Inspect the float for damage or leakage. A crack will
allow the float to fill with liquid and sink thus prevent the
valve form closing. A collapsed float is an indication of
over pressure or hammer and these operation condi-
tions must be corrected before reusing the meter.
