8.10.1 Benchmark 5000 & 6000 Long Term Blower Storage
Benchmark 5000 and 6000 blowers can be damaged if they are left in long term storage
(exceeding 30 days after receipt of equipment). If a Benchmark 5000 and 6000 blower is kept in
storage for more than 30 days, you must complete the instructions below.
Benchmark 5000 & 6000
Long Term Blower Storage Instructions
1. Select a suitable storage site:
•
Level, well-drained, firm surface, in clean, dry and warm location. Minimum temperature
of 50°F (10°C).
•
Isolated from possibility of physical damage from construction vehicles, erection
equipment, etc.
•
Accessible for periodical inspection and maintenance.
2.
The blower should be supported under each corner of its base to allow it to “breath”. Supports
(2 x 4’s, timbers, or railroad ties) should be placed diagonally under each corner.
3.
If the equipment is to be stored for more than three (3) months, the entire blower assembly
must be loosely covered with plastic, but not tightly wrapped.
4.
Storage Maintenance:
NOTE:
A periodic inspection and maintenance log, by date and action taken, must be developed
and maintained for each blower. See example below. Each item must be checked monthly.

1
Re-inspect units to insure any protective devices
used are functioning properly. Check for scratches
in the finish which will allow corrosion or rust to
form
2
Rotate wheel a minimum of 10 full revolutions to
keep the motor bearing grease from separating
and drying out.
(THIS STEP IS CRITICAL!)
5.
General Motor Procedure:
If the motor is not put into service immediately, the motor must be stored in a clean, dry,
warm location. Minimum temperature of 50°F. (10°C,). Several precautionary steps must be
performed to avoid motor damage during storage.
a)
Use a “Megger” each month to ensure that integrity of the winding insulation has been
maintained. Record the Megger readings. Immediately investigate any significant drop
in insulation resistance.
b) DO NOT lubricate the motor bearings during storage. Motor bearings are packed with
grease at the factory.
c) If the storage location is damp or humid, the motor windings must be protected from
moisture. This can be done by applying power to the motor’s space heaters, (IF
AVAILABLE) while the motor is in storage. If the motor does not have space heaters,
