GENERAL DESCRIPTION

An Aro diaphragm pump equiped with the Aro Diaphragm Failure De-

tector warns of a diaphragm failure by sensing the presence of liquid in

the air chamber of the pump. This system uses a liquid sensor in each of

the two air chambers.

OPERATING INSTRUCTIONS

1. Supply voltage for the components can be through the 95087 cable

or through the 95088 adapter (see pinout information on page 2).

2. The cable can be connected to operate an output device as re-

quired (valve, buzzer, light, etc.).

3. To clean the sensors, disconnect the 96270-1 sensors from the

95088 adapter. Unthread the sensors from the air caps. Clean the

prism of the sensors with a mild detergent or water.

WARNING:

Chlorinated hydrocarbons MUST NOT BE USED for cleaning.

See note in 5 below.

4. To reassemble, apply PTFE tape or #80725 Permatex to the

threads of each sensor and thread to the air cap. NOTE: Torque the

sensors to NO MORE THAN 120 in. lbs (13.56 Nm). Reconnect the

sensors to the 95088 adapter.

5. Note: Clean the sensors every 1,000,000 cycles or every 3 months

of use.
