Model 5030 SHARP Monitor Instruction Manual
The "Installation" chapter covers detailed installation instructions. After
proper installation, it is recommended to check the weather-proof
installation at all interfaces exposed to ambient conditions. Ensure that the
condition of the roof flange and silicone caulking will prevent any
precipitation from entering the shelter and possibly damaging the
instrument's electronics.
The leak check of the 5030 SHARP is conducted by first placing the
factory-supplied leak check adapter (Thermo part number 110524-00) on
top of the inlet adapter. Afther the leak check adapter (LCA) is installed,
attach a flow meter on top of the LCA. The addition of the LCA and the
flow meter can cause the instrument to automatically change the filter spot.
Allow the flow rate to stabilize and then document the flow meter reading.
The next step is to remove the LCA and reconnect the flow meter onto the
inlet adapter. Allow the flow rate to stabilize and document the value from
the flow meter. Compare the volumetric flow rate of the flow meter before
and after the use of the LCA and calculate the difference.
It is normal for the 5030 to have a lower flow rate approximately 0.8 alpm
when the LCA is attached compared to without the LCA. If the difference is
less than 0.80 L/min (80 ml/min) the the leack check passes. If it is greater
than 0.8 alpm, check for leaks in the system by checking the various fittings
upstream of the measurement head. If the source of the leak cannot be
found, the instrument requires service by a trained technician.
