2. The filter at the intake for the reactivation air can be cleaned and reused. The filter
is held in place by screws and an access panel (R05), or behind a hinged access
panel (R10 and R15). Remove/lift the access panel and remove the filter.
3. Wash the filter using mild soap and water. Allow the filter to air-dry, or use
compressed air. When the filter is dry, reinstall it.
Do not use any kind of filter coating on the reactivation inlet filter.
This filter is located just upstream of the electric heating
elements. Some filter coatings give off volatile chemicals, which
could be pulled into the heating elements. This could create a
fire hazard. (It is OK to use filter coating on the filter for the
process air, since this air is not pulled through the heating
elements.)
6.5 REMOVING AND REPLACING THE HONEYCOMBE
®
WHEEL
It is important to work carefully when removing and replacing the wheel. The
HoneyCombe
®
section in the center of the wheel can be damaged if it is handled
roughly. Some units have been provided with chain drive mechanisms, while others
have Munters traditional belt drive system.
1. Turn off the unit. Switch off the power supply to the unit and employ lock out/ tag
out procedures.
2. Remove the access panel on the front of the unit. If there is space behind the rear
panel, remove this panel also.
3. At the front of the machine, remove the tensioning spring and press down on the
idler sprocket. See
Figure 6-1 and Figure 6-2 . This will release the tension on the
chain drive. Remove the chain from the drive sprocket, or the belt from the sheave.
4. On the R05 it will be necessary to remove the rear roller wheels in order for the
chain sprocket to clear the roof of the enclosure. Do this while the wheel is
supported by the front rollers. Support the wheel with a block of wood, so that it
cannot roll backward.
The wheel can be heavy, especially on a larger unit. Allowing
the wheel to roll forward suddenly could result in personal injury.
5. If possible, work from the rear of the unit. Remove any braces which run across the
wheel opening. Find a strong board which can be used as a ramp for the wheel.
Set this in place at the rear of the machine.
Be sure the board is strong enough to support the wheel. Be
sure the board is fitted firmly in place.
6. Now it is possible to remove the HoneyCombe
®
wheel. Roll the wheel out of the
rear of the machine.
Be careful to avoid damage to the seals. Until the wheel is clear
of the seals, pull the wheel straight out of the machine. If there
is room, place a helper on the opposite side of the machine to
guide the wheel and push the seals back. Be especially careful
when replacing the wheel.
