INTRODUCTIONThis manual provides information for the followingQR-25 Series, Model 350 (Record of Change 105)compressor versions:

P Control Version Pplain head assembly & no controls

L Control Version Lhead assembly with 2 unloader towers &a hydraulic unloader

S Control Version Shead assembly with 2 unloader towers &a pilot valve

LS Control Version LShead assembly with 2 unloader towers,a hydraulic unloader, & a pilot valvewith a check valve assembly

LVD Control Version LVDhead assembly with 2 unloader towers,a hydraulic unloader, & a pilot valvewith a lockout & check valve

These compressors are aircooled, two stage, twocylinder, pressure lubricated compressors, with upto 200 p.s.i. continuous pressure capability (201 to350 p.s.i. intermittant pressure capability with properconfiguration; consult factory). The Model 350 has a6" low pressure piston bore and a 3.25" high pressurepiston bore and a 3.5" stroke and can be run at 400-940 r.p.m.

Available options included in this manual:

-high pressure rated cylinder and head-spin-on oil filter-hooded air filter-hooded air filter / silencer

CHANGESsince previous printing dated February 1999:

Added maintenance parts to high pressure con-necting rod and piston group: piston assemblies,with and without side sealer piston ring sets.

Changed pipe tee on head assembly from a castfitting to a brass fitting.

WARNING !

SUCTION VALVEUNLOADER ASSEMBLIESDescriptionDescriptionDescriptionDescriptionDescriptionThe Quincy suction valve unloader assembly con-sists of unloading arrangements on the suction valves,having a plunger to contact the suction valve discand an unloader pilot valve (part no.s 110832-***,and 111422-*** & 111423-***) to automatically regu-late the passing of receiver pressure to the unload-ing arrangement.

ApplicationApplicationApplicationApplicationApplicationSuction valve unloader assemblies are recommendedfor use on Quincy compressors where the compres-sor is to run continuously and a constant pressure isto be maintained. The purpose is to automaticallyunseat the suction valve of the compressor when theair supply is greater than the demand.

OperationOperationOperationOperationOperationUnloading occurs when receiver pressure is suffi-cient to overcome pilot valve spring pressure. Thecheck ball is then unseated, allowing receiver pres-sure to pass to the unloading arrangements. Thecompressor will run unloaded until the receiverpressure drops to a predetermined level. At thistime, the action of the ball is reversed, shutting offreceiver pressure to the unloader arrangement andventing the unloader to atmosphere. This allows thecompressor to load. The drive, either electric motoror combustion engine, runs continuously and mustbe started and stopped manually.

Pilot valve 111423-*** can be locked out, formodels equipped with dual control, to provide auto-matic start/stop operation. The knurled knob at thetop of the pilot can be turned clockwise, until it stops,to lock it out. A pressure switch is required to stopthe motor. Failure to use a pressure switch, with thepilot valve locked out, could result in unsafe condi-tions.

A pressure switch must be incorporated whenever pilotvalve 111423-*** is employed as part of the control system.

The compressor will operate in the continous runmode if the knurled knob is turned counterclockwiseuntil it stops.

InstallationInstallationInstallationInstallationInstallationThe pilot valve is to be connected to the air receiverusing a minimum of 3/8" o.d. copper tube. Compres-sors in the field, not equipped with a suction valve

unloader assembly, can be converted to constantspeed. Consult your local Quincy Compressor Dis-tributor for assistance with conversion procedures.

ServiceServiceServiceServiceServicePeriodically check the filter & screens in the inlet ofthe pilot valve to make sure they are free of obstruc-tions. If they become clogged, remove and clean orreplace. Inspect the "o"ring located in the oppositeend of the pilot valve body for wear or damage;replace if necessary.

AdjustmentAdjustmentAdjustmentAdjustmentAdjustmentThe unloading pressure is adjustable and is regu-lated by turning the hex nut (marked "unload adj."in cross sectional illustrations of pilot valves). Turnthe hex nut clockwise to increase and counterclock-wise to decrease the unloading pressure.

The differential (difference between unloadingand loading pressure) is set by turning the hex nut(marked "differential adj." in the cross sectionalillustrations of the pilot valves). Increase the differ-ential pressure by turning the hex nut clockwise -decrease by turning counterclockwise. Tighten thelocknuts after adjustment.
