Pump Unit

The pump unit is housed in a red plastic case. A GX-7 type male
quick connect fitting is located on one end of the pump unit.
This is the inlet fitting to the pump unit. The GX-7 quick connect
is installed in a removable clear plastic filter holder. A cotton
dust filter is inside the filter holder. The filter holder may be
removed by turning it counterclockwise and pulling it away
from the pump unit. Two flat membrane disk hydrophobic
filters and a wire mesh disk are located in the pump unit on the
filter holder end.

The battery compartment is located on the other end of the
pump unit. One AA alkaline battery is installed in the battery
compartment and held in place by a black plastic battery cap.
The battery cap may be removed for access to the battery by
pushing it down, turning it 1/4 turn counterclockwise, and
pulling it away from the pump unit.

The exhaust fitting is located under the battery cap tab.
A POWER button, a power indication LED, and a low flow LED

are located along the middle front of the pump unit. The power
LED is on when the pump unit is on. The low flow LED flashes
when the pump is experiencing a low flow condition.

An instrument release indicator and an instrument lock
indicator are located on the front left of the pump unit. The
indicator tab on the battery cap indicates the current position of
the battery cap.

Inside the pump unit case are the circuit board and diaphragm
pump. There are no user serviceable components inside the
pump unit case except for the battery accessible through the
battery cap and the wire mesh and hydrophobic disk filters
accessible through the filter holder.

The pump unit is configured to mate with the sensor face of the
GX-2009. Retaining tabs on the top of the RP-2009 snap onto the
sensor face of the GX-2009. The GX-2009 must be ins talled so the
front of the instrument is facing the front of the RP-2009. When
installed, the RP-2009 seals to the GX-2009’s sensor face with a
