III. Safety Precautions and
Operating Guidelines
• Read and follow all instructions in this manual. If you have
any questions, consult your Spencer Representative.
• Use appropriately rated lifting equipment for installation,
removal, or disassembly of heavy components.
• Remove inlet and discharge covers, silica gel bags and
crating materials prior to blower installation.
• Inspect all openings for tools and foreign matter before
connecting accessories or piping.
• Perform all installing and operating procedures with care,
following sound practices to avoid accidents and damage.
• Avoid climbing on or over the blower; use proper staging
and ladders for exterior machine access.
• Be sure isolation pads are correctly located beneath the
blower base. See page 5.
• Confirm that the blower is level so that oil level readings will
be accurate.
• Install flexible connectors on inlet and discharge flanges to
isolate piping loads from the blower.
• Ensure that piping, machine guards and accessories such
as filters or valves are properly installed and fastened.
• Fill oilers of oil-lubricated blower bearings with recommended
type of fresh oil as instructed on page 7.
• Install a filter on the inlet when the blower is used in pressure
service and keep it clean.
• Allow only qualified electricians to work on electrical equip-
ment.
• Lock electrical circuits open and tag them during servicing
of equipment.
• Align the coupling as instructed on page 6.
• Remove alignment tools and replace coupling guard before
restarting blower.
• Turn the blower shaft by hand to verify free rotation without
rubbing or noise.
• Check motor rotation as instructed on page 7.
• Do not operate the blower where there is an ambient tem-
perature above 104 °F (40 °C), unless it has been designed
for such conditions.
• Operate blower with sufficient restriction at all times (via
connected piping system or throttled butterfly valve) to
avoid motor overloading.
• Do not allow blower operation in surge (unstable low flow)
or damage may result.
• Rotate shaft of stored or inactive blowers a few times by
hand every week.
• Use only genuine Spencer parts for repairs and service.
IV. Handling and Storage
Each Spencer blower is carefully balanced and tested at the
factory. For optimum performance, it must be handled with
care during unloading and installation.
Check the shipment for damage upon arrival; file any claims
with the shipper and notify Spencer.
Lifting and Moving
Moving of this equipment is the customer’s responsibility and
should be performed or directed by experienced riggers using
accepted rigging practices and safety precautions. The blower/
motor assembly can be lifted and relocated with an overhead
crane or hoist. Always use lifting equipment rated for the loads
involved–see accompanying table of approximate machine
weights.
CAuTIOn: use of alternative lifting methods such as a
forklift is not recommended, due to risk of equipment
damage or misalignment.
