4.12Purge and Outlet Check Valve Maintenance

(Models LS60 through LS760)

WARNING!

Ensure that the dryer is de-energized, valve isolated, and fully depressurized before attempting to remove or disassemble any dryer component or subassem- bly. Failure to do so may result in serious personal injury and/or equipment damage.

Note: The purge orifice [15] is specifically sized and drilled for your dryer. If the purge orifice [5] is lost or damaged, contact your local Deltech Sales Representative for the correct replacement.

Note: Do Not remove shoulder bolts [1] from the valve body [13] unless wear or damage necessitates replace- ment. If replacement is required, apply Loctite™ RC-680 to threads upon reassembly.

1.Clean and inspect all valve hardware upon disassem- bly. Replace all software and any hardware which appears damaged or abnormally worn. Closely in- spect valve poppets [12], check balls [11], purge ad- justing valve [7] and associated mating-sealing sur- faces for any faults which could prevent positive seal- ing.

2.Apply an ultra-thin film of O-ring lubricant to items [3], [5], [9], and [10]. Do not apply lubricant to check balls [11] or valve poppets [12].
