CAUTION: Never perform remote sampling

with the PhD Ultra without the sample probe

assembly. The sample probe handle contains

replaceable filters designed to block moisture

and remove particulate contaminants. If the

pump is operated without the probe assembly in

place, contaminants may cause damage to the

pump, sensors and internal components of the

PhD Ultra.

The sample draw pump includes a unique pressure

sensor designed to protect the PhD Ultra from

exposure to water or other liquids. If there is a

change in pressure in the sample draw assembly

due to fluid intake, the pump immediately shuts

down. After a few seconds audible and visual

alarms indicating a low flow condition will also be

activated.

CAUTION: Insertion of the sample draw tube

into a fluid horizontally or at a low angle may

lead to water ingress and may cause damage to

the PhD Ultra.

The pressure sensor in the sample draw pump is

designed to detect changes while the sample-draw

probe is being held in a vertical position. If the

probe is held horizontally or at a low angle when

inserted into a fluid, a pressure drop sufficient to

cause the pump to shut down may not be generated,

and water could be drawn into the pump assembly.

In order to avoid potential damage, care must be

taken to keep the probe vertical any time fluids

might be present.

2.4.2.1 Using the continuous sample draw pump

(1) Turn the PhD Ultra on.

Figure 2.4.2.1.1. Sample draw pump and probe

assembly

(2) Connect the slip-on battery operated pump with

the hose and probe assembly as shown above

in Figure 2.4.2.1.1.

pump attached

(3) Slip the pump onto the PhD Ultra as shown

above in Figure 2.4.2.1.2.

(4) Make sure the pump is securely attached. (You

should hear a solid “click” as the pump housing

catch engages with the edge of the sensor grill

cover.)

(5) The pump will turn on automatically when

properly attached to the PhD Ultra.

(6) Cover the end of the sample draw probe

assembly with a finger. If there are no leaks in

the sample draw kit components, the pump

should go into a low-flow alarm and shut down,

and the audible and visual low flow alarms

should be activated. A message screen will

identify that there is a low pump flow condition.

A second screen will advise you to remove the

blockage and press “mode” to resume

operation.

Failure to test the pump and

sample draw kit prior to each use may result in

inaccurate readings.

(7) Insert the end of the sample probe into the

location to be sampled.

(8) Wait long enough for the pump to have drawn

the sample through the entire length of hose,

and for the sensors to have stabilized. (Allow

one additional second for each foot or three

seconds for each meter of sample hose.)

Failure to correctly follow the

usage instructions for the pump sample draw kit

may lead to inaccurate readings.

(9) Note gas measurement readings
