right chamber. Both Purge Exhaust Switching Valves will close. The desiccant chambers will im- mediately begin pressurizing to system pressure as indicated by chamber pressure gauges.

10.The Moisture Indicator’s (if dryer so-equipped) bleed valve is installed directly into the back of the indicator’s body. Close the Indicator’s Bleed Valve. FULLY open the Moisture Indicator Supply Valve.

11.Soap bubble test all external piping, fittings, and con- nections. Locate and repair all noted points of leak- age. Do not soap bubble test components lo- cated inside dryer control system's enclosure.

Note: Small leaks noted in inlet piping to the dryer will not affect operation, other than a slight loss of pressure supplied to the dryer. HOWEVER, any gas leaks, (no matter how small), detected at, or down- stream of the dryer outlet MUST BE FIXED to ensure that the dryer will provide a continuous supply of pro- cess gas at specified dew point, to intended points- of-use.

IMPORTANT: Water molecules can diffuse through a pinhole-size leak even though pressure inside the piping is several hundred PSIG. It is not uncommon to have a minute pinhole leak in a gas line cause an increase in dew point from -40°F to -10°F at a dis- tance of forty or more feet downstream of the leak.

12.SLOWLY open the System Outlet Isolation Valve (customer supplied), while monitoring the Outlet Pressure Gauge (if dryer so-equipped). DO NOT per- mit the Dryer's Outlet Pressure Gauge to exceed a 5% drop in pressure while pressurizing downstream piping.

13.Close the System Bypass Valve (if gas system has been so-equipped).

14.Open and adjust the Moisture Indicator’s Bleed Valve until a very slight, continuous gas bleed is felt ex- hausting from the bleed valve’s exhaust port. Ensure that the granular indicator crystals remain motionless after final adjustment.

15.Energize the dryer’s electrical power supply.

16.Refer to Appendix A (Appendix C for -100°F pdp) of this manual and calculate your dryer model's purge pressure setting as instructed.

17.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-stream desiccant chamber has depressurized for regeneration. (When the off- stream chamber is pressurized, the Purge Pressure Indicator will read “system pressure”.)

For dryers with the Hydrobloc Energy Management System: During operation in the Energy Manage- ment Mode, the off-stream chamber may remain pressurized (in ENERGY MANAGEMENT ACTIVE). If this condition is noted, proceed as follows to adjust purge pressure.

a)Open Dryer Control System Enclosure. Locate DIP switches on MEC CPU Board.

b)Switch DIP switch position 7 to OFF position (down). De-energize dryer’s electrical power sup- ply for approximately fifteen (15) seconds; then re-energize. Dryer is now in Fixed Cycle Opera- tion. The off-stream chamber will depressurize to atmosphere for regeneration.

c)Calculate and set purge pressure as previously instructed.

d)Return DIP switch position 7 to ON position. De-energize the dryer’s electrical power supply for approximately fifteen (15) seconds; then re- energize. Dryer should be in Compu-Save En- ergy Saver Mode.

18.The Start-Up procedure for models LS1250 and LS1500 is now complete. Proceed to the Normal Op- eration Checks section of this manual for final opera- tional checks and adjustments.

Dryer Models LS2070 and LS2580

Do not start the dryer with compressed air flow through the dryer. Close customer supplied dryer shut-off valves before beginning start-up procedure.

1.Refer to the General Arrangement drawing as neces- sary for component identification and location while conducting start-up and operational procedures.

Note: If your dryer cannot be started, or fails to start due to special installation or other problems, contact your local Deltech Sales Representative for assis- tance.

2.Remove the Pilot Gas Filter Bowl. Verify that the pi- lot gas filter cartridge is installed. Replace Filter Bowl ensuring that O-ring is properly seated. Close the filter bowl bleed valve.

3.All Prefilter and Afterfilter Assemblies are shipped WITH filter cartridges installed. Verify that prefilter and afterfilter cartridges are installed. Prefilter and Afterfilter cartridges are NOT interchangeable and must be installed in their respective assemblies ONLY. The proper filter cartridge part number is listed on each Prefilter and Afterfilter Assembly.

4.Replace and tighten filter assembly bowls. Ensure that O-rings are properly seated.
