Operation Checks section of this manual for final op-

erational checks and adjustments.

3.5 Normal Start-Up or RestartFor Dryers With Fixed CycleElectronic Timer Control

(Models LS60 through LS1000 only)

1. Close the Pilot Gas Filter's Bleed Valve.

2. Close any manual vent or drain valves installed in

prefilter and afterfilter assemblies.

3. Close the System Outlet Isolation Valve (customer

supplied).

4. Energize the dryer’s electrical power supply.

The following indicator lights will illuminate:

a) POWER ON

b) LEFT or RIGHT CHAMBER DRYING

Note: Should the dryer experience a power inter-

ruption during a normal cycle, the unit will return to

the same status of operation that existed at the time

of the power interruption.

5. Supply pressure to system by slowly opening the

System Inlet Isolation Valve (customer supplied).

The Right Chamber Inlet Switching Valve and Left

Chamber Purge Exhaust Switching Valve will close.

The Left Chamber will immediately begin pressurizing

to system pressure as indicated by the chamber

pressure gauge.

6. PARTIALLY open the System Outlet Isolation Valve

(customer supplied), while monitoring the outlet pres-

sure gauge. Do not permit the Dryer's Outlet Pres-

sure gauge to exceed a 5% drop in pressure while

pressurizing downstream piping.

7. Close the System Bypass Valve (if gas system has

been so-equipped).

8. Refer to Appendix A (Appendix C for -100°F pdp) of

this manual and calculate your dryer model's purge

pressure setting as instructed.

9. Locate the Purge Adjusting Valve. Slowly rotate

dryer’s Purge Adjusting Valve until the Purge Pres-

sure Indicator indicates the calculated purge pressure

setting. (See following Note).

Note: The purge pressure can only be read and ad-

justed when an off-line desiccant chamber has de-

pressurized for regeneration. (When the off-line

chamber is pressurized, the Purge Pressure Indica-

tor will read “system pressure”.)

10. The Normal Start-Up or Restart procedure for mod-

els LS60 through LS1000 is now complete. Proceed

to the Normal Operational Checks section of this

manual for final operational checks and adjust-

ments.

Dryer Models LS60 through LS1000

1. Close the Pilot Gas Filter's Bleed Valve.

2. Close any manual vent or drain valves installed in

prefilter and afterfilter assemblies.

3. Close the System Outlet Isolation Valve (customer

supplied).

4. Energize the dryer's electrical power supply.

5. Supply pressure to system by slowly opening the

System Inlet Isolation Valve (customer supplied).

Both desiccant chamber Inlet Switching Valves will

open and both Purge Exhaust Switching Valves will

close. The desiccant chambers will immediately be-

gin pressurizing to system pressure as indicated by

chamber pressure.

6. Fully open the Moisture Indicator Supply Valve.

7. The Moisture Indicator's (if dryer so-equipped) bleed

valve is installed directly into the back of the

indicator's body. Adjust the Moisture Indicator’s

Bleed Valve until a very slight, continuous gas bleed

is felt exhausting from the bleed valve’s exhaust port.

Ensure that the granular indicator crystals remain

motionless after final adjustment.
