EIP CS90E Industrial Dehumidifier

INTRODUCTION

Designed for a wide range of applications, the CS90E dehumidifier is a rugged, industrial unit which utilizes an energy-efficient compressor and a compact portable design to provide easy efficient drying. The CS90E has a number of special features:

• Compact Size
• High-efficiency rotary compressor
• Ebac’s “Hot Gas” defrost system
• Exterior epoxy powder-coated finish
• Provision for permanent drainage
• Extra long power cord
• Integral condensate pump
• Electronic humidity controller

The fan draws the moist air through the cold evaporator coil, which cools the air below its dew point. Moisture forms on the evaporator coil and is collected in the condensate tray, which is equipped with a permanent drain. The cooled air then passes through the hot condenser coil where it is reheated using the same energy removed during the cooling phase, plus the additional heat generated by the compressor. The air is, therefore, discharged from the dehumidifier at a slightly higher temperature with a lower absolute humidity than that which entered. Continuous circulation of air through the dehumidifier gradually reduces the relative humidity within the area. The CS90E controls consist of an electronic humidity controller, incorporating Bluetooth connectivity and Real Time Clock, allowing the unit to interface with Android and IOS smartphones and provide additional control and data logging features. The respective apps are available for free download through the normal channels Smartphone App The Smartphone interface allows the following additional functions

1. Real-time monitoring of the relay status and room conditions
2. Adjustment of Control and set point (To allow this functionality, the link fitted to J3 on the main controller board, will need removing)
3. Data logging of, Time, Temperature, Humidity, Relay Status, Control and Alarm Set points
4. Adjusting the data Logging Interval
5. Resetting the data log
6. Downloading logged data
7. Emailing logged data in RAW or CSV formats (Allowing importing into Excel)

Download the app from apps.ebacusa.com The CS90E dehumidifier is a rugged, reliable drying unit designed to operate effectively over a broad range of temperature and humidity conditions. An active hot gas defrosts system, controlled by an electronic timer, guarantees positive de- icing, thereby optimizing operation at low temperatures. The unit incorporates a welded and galvanized steel chassis and is finished in an epoxy coating for resilience to damage caused by rough handling.

“This product contains fluorinated greenhouse gases covered by the Kyoto Protocol. The refrigeration system is hermetically sealed. The Global Warming Potential (GWP) of refrigerants used in products manufactured by Ebac Industrial Products Ltd is as follows R134a – 1300 R407c – 1610 For type and weight of refrigerant contained in this unit, please refer to the product data label”

INSTALLATION

Position the dehumidifier unit in the center of the room to be conditioned if at all possible. However if a damp patch is particularly apparent the outlet grille should be pointed towards it.

NOTE: Both inlet grille and outlet grille of the dehumidifier unit must have clear space around them and not be obstructed in anyway. For correct installation and operation the unit must have a clearance of 0.5M from all adjacent surfaces and or structures

WIRING:
Connect the power mains cable to a designated circuit breaker as follows:- For Models without plugs:-

• Brown Live
• Blue Neutral
• Green/Yellow Earth (ground)

If the SUPPLY CORD is damaged, it must be replaced by the manufacturer, its service agent or a similarly qualified person in order to avoid hazards.

DRAINAGE:
The CS90E has an integral water pump fitted as standard. This condensate pump is capable of discharging the condensate water 4.3m vertical lift away from the unit & 30m horizontal. The water can, therefore, be discharged into a drain some distance away. Please attach a suitable hose to the outlet of the unit.

OPERATION

The following procedures should be followed to test the CS90E for correct operation:

1. After unpacking, examine all external features to confirm damage-free shipment. Report all defects and damage at once. Connect the power cable to a grounded 13 Amp electrical outlet.
2. Setting the humidistat
3. Turn fully clockwise
4. Check the dehumidification process as follows:
5. Place unit on a level surface.
6. Start up unit by turning the ON/OFF switch to ON
7. Check that the compressor is running.
8. Leave the machine running for 15 minutes.
9. Observe the evaporator coils through the rear upper grill, to confirm frost operation.
10. If the air temperature is below 80° F, an even coating of frost should cover the entire evaporator coil
11. If the air temperature is above 80° F, frost and/or droplets of condensed water should cover the entire evaporator coil.
12. After a continuous running time of approximately 55 minutes, the unit will enter “Hot Gas” defrost mode for 5 minutes and then automatically return to normal operation.

If, after carrying out the above procedures, the unit does not appear to function properly, refer to the Trouble Shooting section, which follows, or contact the Factory Service Center. TO ENSURE CONTINUED FULL EFFICIENCY OF THE DEHUMIDIFIER, MAINTENANCE PROCEDURES SHOULD BE PERFORMED AS FOLLOWS:

CAUTION:
ONCE THE UNIT HAS BEEN SWITCHED OFF, WAIT AT LEAST FIVE MINUTES BEFORE RESTARTING

ROUTINE SERVICE

WARNING:
ENSURE THAT THE POWER CORD TO THE MACHINE HAS BEEN DISCONNECTED BEFORE CARRYING OUT ROUTINE SERVICE. THE SERVICING AND REPAIR OF THIS UNIT SHOULD ONLY BE CARRIED OUT BY A SUITABLY QUALIFIED PERSON.  To ensure continued full efficiency of the dehumidifier, service procedures should be performed as follows:

1. Clean the surface of the evaporator and condenser coils by blowing the dirt out from behind the fins with compressed air. Hold the nozzle of the air hose away from the coil to avoid damaging the fins. Alternatively, vacuum cleans the coils.
2. Check that the fan rotates freely. The fan motor is sealed for life and therefore does not need oiling.
3. To check the refrigerant charge, run the unit for 15 minutes and briefly remove the top cover. The evaporator coil should be evenly frost coated across its surface. At temperatures above 80°F, the coil may be covered with droplets of water rather than frost. Partial frosting accompanied by a frosting of the thin capillary tubes, indicates loss of refrigerant gas or low charge.
4. Check all wiring connections.
5. in order to check the defrost operation, the unit needs to be operated in an ambient temperature of less than 15°C for at least 1 hour. When operated In this condition the unit should defrost at least once every hour. The defrost mode can be monitored by observing the ice melting on the coil face, prior to defrost the face will show a white coating of frost, which should clear during defrost

IF ANY OF THE PRECEDING PROBLEMS OCCUR, CONTACT THE EBAC SERVICE CENTER PRIOR TO CONTINUED OPERATION OF THE UNIT TO PREVENT PERMANENT DAMAGE.

REPAIRS

1. Should an electrical component fail, consult the Factory Service Center to obtain the proper replacement part.

2. If refrigerant gas is lost from the machine, it will be necessary to use a refrigeration technician to correct the fault. Contact the Factory Service Center prior to initiating this action.
   Any competent refrigeration technician will be able to service the equipment. The following procedure must be used:

3. The source of the leak must be determined and corrected.

4. The machine should be thoroughly evacuated before recharging.

5. The unit must be recharged with refrigerant measured accurately by weight.

6. For evacuation and recharging of the machine, use the crimped and brazed charging stub attached to the side of the refrigerant compressor. The charging stub should be crimped and rebrazed after servicing. NEVER allow permanent service valves to be fitted to any part of the circuit. Service valves may leak causing further loss of refrigerant gas.

7. The refrigerant compressor fitted to the dehumidifier is a durable unit that should give many years of service. Compressor failure can result from the machine losing its refrigerant gas. The compressor can be replaced by a competent refrigeration technician. Failure of the compressor can be confirmed by the following procedure:

8. Establish that power is present at the compressor terminals using a voltmeter.

9. With the power disconnected, check the continuity of the internal winding by using meter across the compressor terminals. An open circuit indicates that the compressor should be replaced.

10. Check that the compressor is not grounded by establishing that a circuit does not exist between the compressor terminals and the shell of the compressor.
