5 OPERATION CHECK & ADJUSTMENT

5.1 PRE-OPERATION CHECK

Danger!

The operator of the system must ensure that all personnel who are involved with installation, operation and maintenance of the machine have read the “1 Safety” sections of

this manual.

1. Inspect and clean the inside of the unit from foreign objects such as rags, tools, particles of metal, and such, that may pose damage to the inside of the unit.

2. If tted, ensure that both air balance dampers are fully open and check that the air paths of the duct work are not obstructed in any way.

3. Check that the lters are securely in place.

4. Conrm both motor overload protectors are set to Start/On position.

5. If tted with condenser or cooler, install a water trap.

6. Conrm thermostat and overheat protection settings are in accordance with table shown “11 Technical data”.

7. Conrm the incoming electrical power cable is secure and ensure that live wires are securely located in the correct terminals. Ensure the earth wire is securely

located onto the earth strap or earth terminal provided.

8. Check that the rating of the electrical supply fuses is correct, see wiring diagram.

5.2 START-UP TEST AND ADJUSTMENT

1. Close and secure all access doors

2. Switch the main switch to “I” and check the supply voltage is correct.

3. Briey start the unit and then turn it o󰀨. Promptly check if the process fan and regeneration fan is rotating in the correct direction. If incorrect check “9

Troubleshooting”. See “6 Operating” on “Start” and “Stop”.

4. If tted, balance the airows, using the dampers in the duct work or adjust the frequency of each frequency converter to obtain the required values.

5. Check the operation of fault alarms by temporarily reducing the setpoints of alarm giving thermostats and motor protectors. Do not forget to reset to the original

settings according to technical data and electrical diagram.

6. Measure the current on both fans and compare with the electrical specications printed on the fan motor casing. If the current is too high, reduce the airow slightly

by closing down on the respective balance damper.

7. If connected, check remote control operation.

8. If connected, check remote alarm function (see 5 above).

9. If connected, check humidistat/electronic humidity controller function.
