Inspecting and Cleaning the Fan
Rebuild the sample pump once every 12–18 months, or as necessary
depending on the environment is is used in. The pump repair kit
contains instructions for rebuilding the pump. See the “ Servicing ”
chapter for a list of replacement parts. Perform the “ Leak Test ”
procedure that follows.
This leak test procedure uses a volumetric flow meter and a custom leak
check adapter. Use the following procedure to verify no leaks.
1. Place a reference volumetric flow meter (e.g., BGI Delta Cal) onto
the inlet adapter and calibrate the 5028 i so that the reference flow
meter and the 5028 i monitor read the same flow rate.
2. Install the custom leak check adapter onto the inlet adapter and
then place the reference flow meter onto the leak check adapter.
3. Record the reference volumetric flow meter reading and the instant
flow reading. If the difference between both readings is less than 0.42
L/min (±2.5%), the leak check passes.
Use the following procedure to replace the filter tape in case of breaks or
if the tape runs out.
Equipment Damage
Some internal components can be damaged by
small amounts of static electricity. A properly grounded antistatic wrist
strap must be worn while handling any internal component. For more
information about appropriate safety precautions, see the “ Servicing ”
chapter.
