Fan belt and pulleys -

 Check fan belt condition and tension to 

ensure it does not slip on pulleys.
Do Not Over Tighten as bearing damage can occur. If the 
belt shows signs of excessive wear or damage, replace as 
necessary. Check to ensure pulleys are secure.

8 Drive Motor

The media drive motor is permanently lubricated and requires 
no maintenance.

8.1 Rotor Drive Belt

A spring loaded tensioner keeps the belt sufficiently 
tensioned. Check the belt for signs of excessive wear. 
Replace as necessary. If additional tension is required, simply 
move the tension spring to a more extended hole as required.

8.2 Seals

All of the high temperature seals which separate the process 
and reactivation compartments, are manufactured specifically 
for Phoenix. Normally, the seals will not require service 
or replacement. However, should damage occur, or if poor 
performance as the result of an air leak is suspected, the 
following inspection must be performed to determine whether 
the seals should be replaced:
Inspection:
1.   Turn the unit off and remove the access covers.
2.   Visually inspect for gaps between the desiccant media 

and the seals.

3.   If significant gaps, wear, or damage are observed, the 

seal needs to be replaced.

8.3 Desiccant Media

The silica gel desiccant media supplied with the dehumidifier 
will last indefinitely under ideal conditions. Due to the nature 
of desiccants they make very good filters. The life of the 
desiccant is directly related to the airborne contaminates 
passed through it. Atmospheric contaminants, exposure to 
acidic gases/or air streams, and contact with petroleum 
based airborne particles can reduce the efficiency of the 
desiccant media. Although the desiccant media is considered 
a cleanable/washable media, the preferred method of 
cleaning is to blow dust out with compressed air. Washing 
the media is not recommended as wash water impurities 
may contaminate the desiccant. Proper filtration and 
preventing contact with chemicals will greatly improve the 
life of the desiccant. Inspect the face of the media to see 
that no surface damage has occurred. If damage is noticed, 
please contact Phoenix for assistance. The rotor should turn 
smoothly upon the shaft, if not check the support bearings.

9 Dehumidifier Service 
Instructions

9.1 Removing Desiccant Rotor

Desiccant rotor removal is accomplished as follows:
1.   Shut off all power.
2.   Remove side access covers.
3.   Push tensioner to loosen belt and remove from drive 

pulley. Allow belt to hang from the rotor.

Remove drive motor pulley, drive motor, and tensioner. 

Note: The rotor may be removed from the reactivation side to 
eliminate the need to remove the drive components.

4.   Support rotor as necessary with a block of wood or 

similar device. Remove the cap screws securing the 
rotor center shaft.

5.   Pull on drive belt to slide media slightly toward the front 

(process side) of the unit. Remove the rotor shaft and 
shaft washers.

6.   Remove the rotor from the cabinet by pulling on the 

drive belt.

To re-install media, reverse the above procedure.

NOTE: Drive belt must be around perimeter of media before 
re-installing! Make sure the seal does not roll off of the 
divider during media installation. Carefully push perimeter 
seals into place (roll out on rotor panels) with a putty knife 
or similar tool. Be careful not to cut or damage seal. This can 
be assisted by rotating the rotor as the seal is smoothed into 
place.

9.2 Changing Seals

1.   Follow procedure for removing media.
2.   Remove the clamp ring holding the seal in place by 

loosening one of the clamp screws.

3.   Remove seal from media.
4.   Repeat above steps for opposite side.

9.3 Installing Seals

1.   Replacement seals as shipped from the factory require 

field fitting (cutting to length).

2.   Dry fit the seal to perimeter and divider panel length. 

Cut replacement seals to length of original seals.

3.   Ensure that the cassette face panels are clean.
4.   Apply the perimeter seal around wheel. Approximately 

1/2” of seal will extend past the face of the rotor. 
Install clamp and loosely tighten. Adjust seal and clamp 
position as required and tighten clamp screws. Repeat 
this procedure for the opposite face. (Ref. Figure A).
