OPERATION
1. Determine criteria for your testing from NFPA or ISO publications, or other
authority.
2. Connect Test Kit swivel inlet to hydrant or other fixed 2 1/2" discharge
device. (For best results, the test kit should be preceded by minimum 3
foot long straight, open 2 1/2" waterway.)
3. Loosen thumbscrews and rotate pitot blade out of stream
position.
4. Select from the Discharge Table, the preferred tip diameter for the expected
flow. Install the tip as follows:
a. Unscrew lock ring.
b. Pull out gray tip. (Caution: do not use tools which may damage water-
way).
c. Insert proper size tip completely until retaining ring is snug against noz-
zle body.
d. Screw on lock ring clockwise until tight.
FAILURE TO REPLACE LOCK RING MAY ALLOW TIP TO
BLOW OUT, CAUSING DAMAGE OR INJURY.
5a. Hydrant: Open hydrant and flush rocks, etc. Rotate blade back into center
of stream and tighten thumbscrew. Record pressure reading.
5b. Pumper: After warm-up, bring pump up to desired speed and close throt-
tling valve(s) to set discharge pressure at required rating. Rotate pitot blade
into stream center and tighten thumbscrew. Record pressure reading.
6. When hydrant or pumper must continue to operate (e.g. endurance test),
rotate blade out of stream between readings to reduce wear and avoid
damage.
7. Read flow at intersection of tip size and pressure in Table. DO NOT apply
additional hydrant coefficients since the nozzle tip replaces the hydrant
outlet as the orifice.
8. After use, open bleeder valve and drain any water in the pitot air chamber.
Draining is especially important in freezing weather.
