The flowmeter and humidifier column must be checked daily to insure

proper flow, and corrected as necessary. Refer to Section 2.2:

Humidifier

and 4.4:

Throttle Valve

5.2 Cell Electrolyte Level5.2 Cell Electrolyte Level

5.2 Cell Electrolyte Level

The level of electrolyte in the cell must be checked daily and adjusted

as necessary. Refer to Section 4.2.3:

Cell Installation

. The proper level for

the electrolyte is when the bottom edge of the sensor screen is wetted but not

immersed. Approximately 3/32 " of the silver electrode should extend into the

pool of electrolyte.

5.3 Reservoir5.3 Reservoir

5.3 Reservoir

The water level in the reservoir should be checked at least every two

weeks. Follow this procedure:

a) Remove the cap from the filler spout.

b) Obtain a clean glass tube about 4 to 5 inches long and about ¼ "

outer diameter.

c) Lower the tube into the tank through the filler spout until it

touches bottom.

d) Place a finger over the end of the tube, and withdraw the tube

from the tank. The height of water in the tube is the height

of the water level in the tank.

e) If the water level in the reservoir is below 1 "1 "

1 "1 "

1 ", add a quart of

distilled water.

f) Replace the filler spout cap securely after verifying that the O-

ring seal is in good condition.
