6. MAINTENANCE
DANGER
The blower and parts may contain hazardous media. Assure that blower
and parts are evacuated of hazardous media prior to servicing.
CAUTION
The electrical service must be isolated and de-energized prior to
maintenance. Apply appropriate procedures to assure electrical supply is
de-energized and cannot be inadvertently energized during maintenance.
Assure piping and product is isolated prior to maintenance of blower. Apply
appropriate procedures to assure piping and product is isolated and that
inadvertent opening of valves cannot occur during maintenance.
CAUTION
During routine maintenance, inspect and assure that guards are in place
and secure.
NOTE
Current regulations require Material Safety Data Sheet to be completed and
forwarded to Tuthill Corporation on any unit being returned for any reason
which has been handling or involved with hazardous gases or materials.
This is for the protection of the employees of Tuthill Corporation who are
required to perform service on this equipment. Failure to do so will result
in service delays.
6.1 OIL INDICATOR, FILL AND DRAIN
The Qube oil can be completely serviced from the front of the machine, see Figure 4. An indicator is
provided to show minimum and maximum oil levels. The oil can be drained by removing the drain cap. Oil
can be added via the clear plastic reservoir. Check oil level only when the machine is shut-down.
6.2 AIR FILTER
Your Qube is equipped with an air filter (except closed-loop systems) designed for minimum pressure loss
and proper filtration of atmospheric inlet air. The air filter element is a disposable pleated paper, radial fin
type. We recommend regular replacement of the filter when pressure loss exceeds 15 inches (38 cm) of
water column pressure loss.
Optional filter elements (felt, wire mesh, polyester) are available, consult factory.
NOTE
DO NOT USE COMPRESSED AIR TO CLEAN THE FILTER ELEMENT.
This can result in damage to the filter media and reduce its filtration
effectiveness. NEVER operate your Qube without adequate inlet air
filtration or unwarrantable damage to the blower can occur.
Remove and replace filter element as follows:
1. Turn off and lock out power to your Qube.
2. Remove top panel door. (5/16” hex head wrench required).
3.
Remove the filter retainer housing nut and washer.
4.
Remove the filter cover housing off the threaded stud.
5.
Remove the element off the filter base plate.
