pressure. Units are shipped without export crating unless
crating has been specified on the Sales Order.
If the unit is to be put into storage, prior to installation, the
following precautions should be observed:
Ensure that the unit is not exposed to rain.
Ensure that all openings, such as water connections, are
securely capped.
The unit should be stored in a location where there is
minimal activity to limit the risk of accidental physical
damage.
To prevent inadvertent operation of the pressure relief
devices the unit must NOT be hot water or steam cleaned.
It is recommended to let the functionary on the storage
site keep the key of the control board.
It is recommended that the unit be periodically inspected
during storage.
If the unit is stored longer than six months, the relative
requirements for Long-Term Storage (50.20-NM9 /50.20-
CL9 / 50.20-NM1) must be followed.
3.2 INSPECTION
The unit shipment should be checked on arrival to see that
all major pieces, boxes and crates are received. Each unit
should be checked on the trailer or rail car when received,
before unloading, for any visible signs of damage. Any
damage of signs of possible damage must be reported to the
transportation company immediately for their inspection.
When received at the job site,all containers should be
opened and the contents checked against the packing list.
Any material shortage should be reported to YORK
immediately.
3.3 RIGGING
Each unit has four lifting holes(two on each end) in the end
sheets which should be used to lift the unit. Care should be
taken at all times during rigging and handling to avoid
damage to the unit and its external connections. Lift only
using holes shown in Figure 3-1.
If optional shipping skids are used, remove them before
lowering the unit to its mounting position. Rig the uni to its
final location on the floor or mounting pad by lifting the
unit (or shell assembly) with an overhead lift and lower the
unit to its mounting position.
Don't move the unit on rollers, nor lift it by forklift.
