READ THIS MANUAL
This manual is provided for the MS-600 dehumidifier so the user can gain a thorough
understanding of the proper set-up, operation, and maintenance. This dehumidifier is built around
tested engineering principles and has passed a thorough inspection for quality of workmanship
and function. A thorough understanding of the set-up, operation, and maintenance of this
equipment will allow it to provide maximum performance and reliability.
PRINCIPLES OF OPERATION
The MS-600 is a self-contained desiccant dehumidifier designed to efficiently remove water vapor
from the air. A portion of the desiccant rotor is exposed to the “process” air effectively adsorbing
moisture while the second portion of the rotor is exposed to heated “reactivation” air effectively
removing the adsorbed moisture. This process is done on a continuous basis, providing constant
dehumidified process air.
MACHINE SET-UP
-Carefully remove the machine from its shipping carton.
-Thoroughly inspect the machine for shipping damage. Should any damage be found, report the
damage to the freight company immediately.
-Carefully place the machine on a level surface within the space to be dried.
-Connect 10” hoses to the process inlet and outlet as required for the drying project.
-Connect 10” hoses to the reactivation inlet and outlet as required for the drying project.
CAUTION-Do not pinch or kink the hoses. Blockage of the hoses will result in reduced airflow
and moisture removal capacity.
-Check to ensure the machine is turned “off” prior to connecting power. Circuit breakers are
provided in the control enclosure. Check that they are switched “on” once power is applied.
-Connect an appropriate power cord and locking connector to the flanged inlet receptacle
provided at the rear of the machine. The cord should be connected to 220vac power with 30a
breaker or fuse with proper grounding.
-Unit is intended for indoor operation and needs to be protected from the weather
OPERATION
Machine operation is fully automatic and requires no adjustments to airflow or other primary
functions.
- 1 -

A “POWER ON” lamp is provided to indicate that power is applied to the machine.
A “RUN” lamp is provided to indicate that the unit is operational. This lamp will be illuminated
when the “ON-OFF” switch is in the “ON” position.
Switch the “ON-OFF” to the “ON” position. The machine will start operating. At this point, both
fans, reactivation heaters, and rotor drive will be operational.
If humidity control is desired to prevent over drying, a flanged receptacle is provided for a
remote humidity sensor. Connect the appropriate plug and humidity sensor with dry contacts
only-DO NOT APPLY VOLTAGE TO THIS CIRCUIT. Open the control enclosure door and
switch the “AUTO/MAN” switch to the “AUTO” position. The reactivation fan, heater, and drive
circuit will now cycle on and off from the humidistat input.
An hour meter is provided to track time of operation for to aid in scheduling inspection and
maintenance.
CONTROLS/ELECTRICAL
- 2 -

The controls in this machine are UL listed and provide for automatic operation and all required
protection of the machine components. Access to the control panel is via a hinged access cover.
Air flow is accomplished using internal motorized impellers for process and reactivation air. The
process fan will operate any time the “ON-OFF” switch is in the “ON” position.
A fractional hp gear motor drives the desiccant rotor.
Self-regulating PTC heater elements provide the “heat source” for reactivation.
MAINTENANCE
This machine is designed for minimal maintenance and years of trouble free service.
Clean the exterior of the machine with a damp cloth and mild soap if necessary.
DO NOT use a garden hose or pressure washer to clean this machine !
Occasionally inspect internal components for loose fasteners or damage from handling.
Inspect the flanged power inlet, connector, and cord for damage.
Check to ensure all access panels are in place and secure.
Air Inlet Filters (2 ea. 10x10x2” pleated)
Filter access is accomplished by removing the inlet collar plates for the process (10” collar, top)
and reactivation filter (10” collar, bottom).
Inspect filters regularly and replace if dirty. Regular air filter maintenance is critical to extending
the life of the desiccant rotor and moisture removal efficiency.
Keeping filters clean is the most important long term maintenance on this machine !
- 3 -

In dusty or dirty environments, the filter replacement interval will be greatly reduced. The hour
meter provided can be used to establish a filter replacement interval.
Motorized Impellers (blowers)
The motorized impeller motors provided in this machine require no maintenance. They are sealed
and permanently lubricated.
Desiccant rotor drive system
The rotor drive system consists of a fractional hp gear motor, timing pulley, timing belt, and spring
tensioner. The gear motor is sealed and permanently lubricated. Check the motor fasteners and
timing pulley to be secure. Inspect the timing belt for cracks, tears, or abrasion. The tensioner
should keep slack form the belt with light tension.
Rotor Seals
Periodically inspect the rotor seals for damage, tears, or gaps.
Reactivation Electrical Heaters
The heating elements are self regulating PTC type and require no maintenance.
Heating surfaces of element are “live” conductors.
DO NOT TOUCH ELEMENTS WITH POWER APPLIED !
