4.3.1 LEVELING
The Qube blower system should be placed on a level, even, flat, vibration-less surface to avoid equipment
damage. The Qube blower system shall be level to 1/8” per 10 feet (this equates to a leveling tool with an
accuracy of at least 0.001”/in., readily available levels have accuracy of 0.0005”/in.). Level the unit and
adjust with shims as required.
NOTE
An un-level unit can result in improper oil level and catastrophic failure of
the unit.
4.3.2 FOUNDATION
Your Qube blower system does not need a special foundation, however it does require a solid, level floor
and adequate frame support. Bolt the blower system to the floor and seal any cracks around the perimeter.
4.4 SAFETY
DANGER
Assure that properly sized pressure relief valves and vacuum breaks/relief
valves are used on the inlet and outlet side of the blower.
WARNING
Use lock out/tag out procedures to disable the electrical energy source
before any service or work is done on the blower.
4.5 COOLING AIR INTAKE AND DISCHARGE
To minimize maintenance, supply your blower with the cleanest air possible. It is important that the air does
not contain any flammable or toxic gases, as the blower will concentrate these gases. This could result in
damage to the unit and surrounding property and lead to personal injury or death. The louvered area in the
rear of the Qube enclosure provides blower air intake (on atmospheric inlet systems) and air intake for the
cooling fan. Do not block or restrict this opening or the blower and/or motor may overheat and fail.
The supply air for the cooling fan is provided through the blower air intake louvers, located on the lower
side of the Qube enclosure. Do not block or restrict this opening or the blower and/or motor may overheat
and fail.
Likewise, the cooling air discharge, located on the upper side of the Qube enclosure, must be free from
restriction or blockage. Any ducting or louvering must not exceed .25 inches of water column (60 Pa) static
head. Excessive restriction to the discharge cooling air will cause the blower and/or motor to operate at
elevated temperatures, possibly resulting in overheating and failure. Ducting of cooling air to the unit is not
generally recommended.
WARNING
Do not use air blowers on explosive or hazardous gases. Each size
blower has limits on pressure differential, running speed, and discharge
temperature. These limits must not be exceeded. Consult the manual
of the blower model being used for details pertaining to the allowable
performance criteria.
