MODEL 841 TEST KIT
BASIC OPERATING INSTRUCTIONS
1. Connect hoses to test connections - red high pressure
hose upstream; green low pressure hose downstream.
2. Open valves on device being tested, and read differential
(or flow).
3. Upon completion of test, close valves, disconnect hoses
and store them in test kit case.
NOTE: The 841 Test Kit is equipped with filters near the ends
of the hoses. If the gauge responds slowly to changes in diffe-
rential pressure, the filter elements may be partially plugged.
To remedy this, unscrew the two halves of the filter housing
and remove the brass filter element. It may be cleaned by
flushing with a mild detergent and water. If, after reassembly,
this has not satisfactorily improved the response time, replac-
ement filter element kits (#98008) should be installed.
Please see back page for standard materials of construction,
maximum safe working pressure, temperature limitations,
replacement parts information, etc.
