14.1.1 Air Flow Check
It is essential that proper airflow is maintained within the DPU. There is one (1) fan system,
accessible via the top hatch of the DPU, which provides an air intake and exhaust.
The air intake fan located at the top corner of the DPU draws air into the unit to cool internal
components. This fan intake should be cleaned at least once every three (3) months. Similarly,
the fan exhaust is located opposite the intake fan and expels warm air away from the unit.
14.1.2 FRM Maintenance
It is necessary to visually inspect the FRM unit in order to ensure it has not been tampered with
and has maintained integrity. As a minimum, follow the steps provided below during visual
inspection:
1. Ensure the capsule is undamaged in any way.
2. Check to ensure the integrity of the securing brackets. There should be no signs of
tampering.
3. Check to ensure the exterior paint and labelling are fully visible and in excellent condition.
There should be no signs of chipping or flaking.
