Filling The AirPrep Air Dryer System With Deliquescent/Desiccant
7.1.1. The AirPrep System must be completely depressurized before filling can begin. Follow
the depressurizing procedure in Section 6.2.
Airborne particles and loud noise hazards from blowdown exhaust air can cause serious
injury and loss of hearing. Wear approved eye and ear protection. Stay clear of
blowdown air path. DO NOT place hands or other body parts in the blowdown air path.
Make sure no personnel are in the blowdown air path.
7.1.2. Open the pre-filter drain ball valve (#7) to check for air flow. No air flow indicates that
the AirPrep System is depressurized. See Figure 7.1.
7.1.3.
Remove the handway cover (#10) at the top of the separator tank (#20).
7.1.4.
Check inside the separator tank for looseness of the deliquescent/desiccant tablets (#14).
Extended exposure to moisture will fuse the tablets together and can possibly block or
restrict air flow. Break apart fused tablets with a long rod or similar device. Fill with
tablets to the top of the separator tank (#20).
7.1.5.
Re-install the handway cover and gasket (#10). See Section 6.3 for installation
procedure.
7.1.6.
Only after completing all the pre-operation procedures in Section 6.0 and 7.1, and the
AirPrep System is then pressurized per Section 7.2, check the handway(s) (#10) for
leaks. Periodically check the handway(s) for leaks thereafter.
