AAF International PRU - Manual (Page 2)

NOTE
The AAF Recirculation Unit (RU) and Pressurization and Recirculation
Unit (PRU) filter systems and filters are similar in most respects. For
ease of reading, this manual will refer only to the Recirculation Unit
(RU). Unless specifically stated otherwise, all references to the
Recirculation Unit (RU) will apply equally to the Pressurization and
Recirculation Unit (PRU). A detailed description of both systems can
be found in section 2.0, Principles of Operation.
1.2 Packaging and Shipping, Receiving and Inspection, Handling
and Storage
1.2.1 Packaging and Shipping: Unless otherwise defined in the
purchase order and agreed by AAF, the RU filter housing and filters
are packaged for domestic transit and shipped FOB the AAF
factory. The method of shipment will be as specified in the
customer’s purchase order to AAF.
1.2.2 Receiving and Inspection: Obtain a copy of the purchase
order, the product drawing that was submitted by AAF in
association with the order, and a copy of the bill of lading, along
with any other shipping papers. Upon receipt of the equipment, or
any part thereof, these documents shall be used to ensure that the
correct product has been received.
For maximum protection, complete the following steps upon receipt
of the RU and filters:
– Inspect the shipment and all associated documentation. Notify
the carrier immediately if there is any visible damage to the
packaging or the equipment, or a discrepancy in the shipping
papers. If necessary, file an immediate claim with the carrier
against such damage or discrepancy.
– Confirm that the equipment received agrees with the contents
of the shipping papers.
– Confirm that the shipping documents agree with the purchase
order. Refer to the product drawing submitted for the order as
necessary.
– If it is determined that any equipment ordered on the purchase
order has not been delivered and is not accounted for in the
shipping papers, contact AAF International immediately by calling
1-800-477-1214. Reference the AAF control number which will
be listed on the shipping papers.
Each shipment may include:
- One or more individually packaged RUs.
- Packaged particulate filters.
- Packaged gas-phase chemical filter cassettes.
Note that the RU and the particulate and gas-phase filters may
ship from different locations and be received at different times.
1.2.3 Handling and Storage: Following receipt, inspection, and
acceptance of the equipment, and prior to installation, the RU and
the particulate and gas-phase filters shall be handled with great
care. The RU may ship mounted vertically or horizontally on a pallet
for protection during shipping and handling. It is recommended that
it remains on its pallet until it has been moved to its final installation
location. Only personnel experienced in rigging and handling
equipment shall be employed for this task. In most cases, the RU
may be moved using a forklift. A suggestion for rigging horizontally
shipped equipment is shown in Figure 1. Rig the housing using
straps or a sling. Fasten the strapping under the skid on which the
RU ships. To prevent damage to the exterior surface of the RU, use
spreader bars at all times. Position the spreader bars to keep the
cables from rubbing against any part of the housing. Before
hoisting, make sure that the load is properly balanced.
! WARNING: The housing top (when shipped vertically) or the top-side
(when shipped horizontally) will not support the weight of the unit. Any
attempt to support the housing from these surfaces may result in serious
equipment damage and severe personal injury. Do not walk on the top or
the top-side of the unit, or use these surfaces for storage of materials.
The components shall be retained and stored in their protective
packaging until immediately prior to installation. Care shall be taken
to ensure that the packages are not dropped or subjected to any
impact loads.
At all times the equipment shall be protected from exposure to
weather. The equipment shall be stored in a clean, dry, temperature
controlled environment. All items shall be stored on pallets so that
they are elevated above grade. Recirculation Units (RU) shall not be
