pressurized for regeneration. (When the off-line chamber is pressurized, the Purge Pressure Indica- tor will read “system pressure”.)

13.The Normal Start-Up or Restart procedure for mod- els LS2070 through LS2580 is now complete. Pro- ceed to the Normal Operational Checks section of this manual for final operational checks and adjust- ments.

3.7Normal Operational Checks

1.Ensure that the dryer is being operated at the correct inlet pressure, flow rate, and inlet temperature, as specified on the Dryer Specification Label (located on inside cover of dryer system control enclosure).

2.If the prefilter utilizes any automatic drain device, en- sure that it is draining and functioning properly.

3.Ensure that the Purge Pressure Indicator (gauge) in- dicates the pressure setting calculated during start- up.

4.After an off-stream desiccant chamber has depressur- ized for regeneration, a flow of purge gas should be felt exiting the purge exhaust muffler. The regenerat- ing chamber’s pressure gauge MUST indicate zero (0) PSIG throughout the purging period.

5a. The dryer controller should automatically switch the system from left to right and right to left chamber dry- ing on a fixed time cycle. If the system fails to switch drying chambers twice within its designated NEMA Cycle, refer to the TROUBLESHOOTING GUIDE.

5b. If a Hydrobloc Compu-Save Energy Management System Control indicates a High Humidity Warning upon start-up, it should automatically shift to EN- ERGY MANAGEMENT ACTIVE within twenty-four

(24)hours of start-up. If system fails to shift to EN- ERGY MANAGEMENT ACTIVE within this time pe- riod, refer to the TROUBLESHOOTING GUIDE and conduct checks listed for HIGH HUMIDITY WARN- ING (See following Note.)

Note: The system will operate in a fixed cycle ac- companied by a HIGH HUMIDITY WARNING until the desiccant beds have been regenerated to the extent necessary to provide a process gas supply at the dryer’s rated dew point. The control system will then automatically shift to ENERGY MANAGEMENT AC- TIVE. During normal dryer operation (ENERGY MAN- AGEMENT ACTIVE), the off-stream desiccant cham- ber will depressurize and begin regenerating (purging) ONLY when the need for a regeneration cycle is sensed by the chamber’s Compu-Save Humidity Sensor. Otherwise, the off-stream chamber will re- main pressurized.

6.If the dryer has a Moisture Indicator and the Indicator’s granular indicating gel is pink at the time of dryer start-up, a color change to blue should be noted within twenty-four (24) hours. Ensure that the indicator’s bleed valve has been adjusted as in- structed in the start-up procedure.

7.Ensure that the System Inlet and Outlet Isolation Valves (customer supplied) have been fully opened.

8.Ensure that the dryer control system’s enclosure cover is closed with all latches tightened to prevent entrance of moisture, dust, dirt, etc.

9.SHUTDOWN AND DEPRESSURIZE DRYER follow- ing two (2) to three (3) weeks of initial operation. In- spect desiccant beds through fill ports, for settling. If settling has occurred, refill chambers as necessary to bring desiccant levels to bottom of each desiccant retaining screen. Do Not Tamp or Ram Desiccant.

3.8Dryer Shutdown

1.De-energize the dryer’s electrical supply. When the dryer’s power supply is de-energized, both desiccant chambers will be automatically placed on-stream.

2.Close the System Outlet Isolation Valve (customer supplied).

3.Close the System Inlet Isolation Valve (customer sup- plied).

IMPORTANT: Inlet and Outlet Isolation Valves MUST be closed to prevent moisture overloading of desiccant beds, due to continuous flow without regen- eration.

4.Close the Moisture Indicator Supply Valve (if dryer has been so-equipped). This MUST be done to prevent depressurization of the pilot gas supply, which in turn, will eventually result in dryer depressurization.

5.Shutdown is now complete. The dryer may be left pressurized during periods of non-use, if desired. However, if any servicing or maintenance is to be per- formed, ensure that the dryer is depressurized BE- FORE beginning work. Proceed to Step 6 for depres- surization instructions.

WARNING!

Ensure that the system is de-energized, valve isolated, and fully depressurized before attempt- ing to remove or disassemble any component or subassembly. Failure to do so may result in se- rious personal injury and/or equipment damage.

6.To depressurize dryer, proceed as follows:

a)Open customer-supplied System Bypass Valve (if gas system has been so-equipped).
