2-15. OPERATION OF AUXILIARY EQUIPMENT.
Generator sets must not be operated in enclosed areas unless exhaust discharge is properly vented
to the outside. Be alert at all times during operation for odors and exposure symptoms to carbon
Operating noise level of the generator set can cause hearing damage. Ear protectors, as
recommended by medical/safety personnel, must be worn working near unit.
Generator Set (Models WPES-10 and H-9518-1). Instructions for operating the generator are contained in the
applicable generator set manual (TM 5-6115-465-12 for NSN 6115-00-118-1240).
Chemicals used for operating ROWPU can kill you. The chemicals alone or in mixture can be
dangerous. ALWAYS wear protective apron, goggles and gloves and make sure area is well
Color Comparator Test Kit. Instructions to determine the pH values and chlorine residual in water are contained
in the color comparator test kit (para. 2-2m, figure 2-20). The Diethyl-P-Phenylene diamine (DPD) tablets are not
part of the test kit, but are included in the storage chest.
TDS Meter. Refer to figure 2-75. The total dissolved solids (TDS) meter is a calibrated meter that measures how
much electric current can flow through a sample of water. Pure water passes almost no current.
Description of the TDS meter:
Reads in ppm (parts per million) or in mg/l (milligrams per liter). Ppm is the same as mpl.
Has four modes:
S - Calibration mode
10 Mode - Range is from 0 to 50. Result is achieved by multiplying indication times 10.
100 Mode - Range is from 0 to 500. Result is achieved by multiplying indication times 100.
1000 Mode - Range is from 0 to 500. Result is achieved by multiplying indication times 1000.
When using range extender (in 1000 mode) range is 0 to 10,000. Result is achieved by multiplying
indication times 10,000.
