INSTALLATION
CAUTION!
WARNING!
SEE FIGURE 1 FOR ITEM NUMBERS
MOUNTING FLANGES
Mounting flanges are identical for all whistles, single or
chime tone
Flanges are fitted with four 9/16” holes, equally spaced and
straddling center line on a 3” bolt circle. Center tapping is
provided for ½” (40 schedule) air supply pipe.
When mounting whistle on appropriate companion flange or
bracket. (Where flanges are used, insert soft gasket between
flanges). Bolt securely in place with 10 ft-lbs torque.
Connect corrosion resistant air supply line to companion
flange or directly into whistle where whistle is mounted on a
bracket. Fit air line with appropriate stop valve, air strainer,
and operation valve.
MAINTENANCE
CLEANING DIAPHRAGM AND
DIAPHRAGM HOUSING
To inspect diaphragm housing (6) and diaphragm (3), remove
back cover bolts (2) and take off back cover (1). Remove
diaphragm from back cover.
Clean all parts thoroughly. After nozzle is clean, wipe on a
very thin film of oil to lubricate.
Orifice Dowel Pin is permanently fastened to whistle
and should not be removed unless replacement is
necessary. If replacement is necessary, consult proper
drawing for reference number of correct Orifice Dowel
Pin.
Whenever a back cover is removed, it is good practice to blow
out the air lines supplying the whistle and blow out the orifice
dowel pin area.
Reassembly
Place back cover with diaphragm on diaphragm housing (6).
Replace bolts (2) and tighten bolts alternately.
WARNING!
When reassembling whistles to bases or back covers to
housings. Be sure that all joints are evenly with the
proper tightening sequence (see Fig 5) so that air
leakage will not occur.
NOTE!
DISASSEMBLING POWER CHAMBER AND
HORN
To disassemble power chamber and horn from base (11),
remove capscrews (9) and lockwashers (8) and slide horn and
power chamber from base. Take off gaskets (7). To dismantle
power chamber follow instructions above.
Reassembly
Slide horn and power chamber into base (11). Tighten
capscrews (9) in sequence (see Fig 1).
REVERSING WHISTLE
To reverse a whistle, dismantle as described in
“DISASSEMBLING POWER CHAMBER AND HORN”
section and reassemble in the opposite position. In all cases,
be sure that sufficient clearance exists between horn bells
before tightening in reverse position.
REPLACING ORIFICE DOWEL PIN
If is ever necessary to replace an orifice dowel pin, insert it
into horn with orifice facing outward and in line with rib of
horn. Prick punch horn metal around orifice dowel pin to hold
it in place.
The piping system must be adequately designed and
supported to prevent extraordinary loads to the
pressure equipment.
Injury or death can occur due to failure to completely
isolate valve from all sources of pressure before
beginning disassembly. Do not proceed until whistle
has been completely isolated from the process and
vented to atmosphere.
