Drain old fl uid from FYRITE and rinse all parts in clean, lukewarm water.
NOTE: FYRITE fl uid is corrosive to skin, clothing, some met-
als, and painted or lacquered surfaces. Dispose of these fl uids
in accordance with Local, State and Federal Laws. If draining
into a porcelain sink is permitted, keep water faucet turned on
while draining and fl ush for at least 1/2 minute afterwards.
NOTE: Examine top gasket for warpage, if distorted as shown
in Figure 22, replace gasket with part # 11-0143 before proceed-
ing.
Drain all parts of excess water. Stand FYRITE Body upright to center replacement
Top Gasket in recess provided in top fl ange of body.

gas (Figure 21) or be prompt in reassembling Top Cap to prevent excessive fl uid con-
tact with air.
Uncap FYRITE fl uid bottle, invert FYRITE and place over the bottle. Invert both
FYRITE and bottle (Figure 21a) so that FYRITE comes to an upright position and the
fl uid is fi lling the unit. Immediately install plastic Top Cap Assembly and metal Top
Cap Ring without delay.

FYRITEs: Make certain that Top Cap Ring Gasket (11-0109, Figure 33) is in
place between metal Top Cap Ring and plastic Top Cap. Draw the 4 machine screws
down with light screwdriver force.
Then, going from one screw to the next, draw down 1/4 turn until all are fi rmly tight-
ened. Avoid excessive force in tightening which may damage plastic parts.
6.4 Inspection of FYRITE for Fluid Leakage
Gradual loss of fl uid, moisture or dried encrustation around Plunger Valve does not
indicate fl uid leakage. Gas enters and leaves unit during sampling with considerable
velocity and some fl uid vapor is carried out during normal sampling. To check Top As-
sembly for fl uid leakage in upright position, depress Plunger Valve and release.
Note the scale reading at top of fl uid column, and then stand FYRITE upside down
overnight in glass or porcelain test dish (See Figure 23). Then, return FYRITE to up-
right position and, after allowing 5 minutes for drainage, depress and release Plunger
Valve. Leakage will be evidenced by lower scale reading. Extreme leakage will be ap-
parent by presence of fl uid in test dish.
Follow the same procedure to check fl uid leakage from Bottom Cap Assembly with
FYRITE stood overnight in the upright position.
When leakage is proven, examine plastic and rubber parts for deterioration to deter-
