HOW TO USE THE PARTS AND COMPONENTS ILLUSTRATED PARTS LISTING Disassembly Order System The disassembly order system used in the parts list shows the relationship of one part to another. For a given item, replaceable parts making up the top assembly or subassembly depicts the relationship of the item to the associated next higher assembly. Indenture is not used in this illustrated parts list due to the relative simplicity of these units. Number Column (No.) This column contains the callout or index number of a part on the exploded view assembly drawing. Each number corresponds to a specific part on the drawing. When a triple dash (---) is shown, the part is either the top assembly for the drawing, or the part is not illustrated and therefore not called out. The illustrated parts list does not list or illustrate parts which lose their identity by being permanently welded or riveted to other pieces. Description Column (Description) This column lists the noun name of the item followed by any descriptor (Example: GAUGE, LOW SIDE). In this case “GAUGE” is the noun, and “LOW SIDE” is the descriptor. Units Per Assembly (Qty) The Qty column shows the total number of numbers required per assembly, per subassembly, and per sub-subassembly as applicable. For bulk items, the letters AR indicate “as required”. The letters REF, if used, indicate the item is listed for reference purposes. Part Number Column (Part No.) This column contains the part number of the item listed in the Description column. The letters RNS, REF, or the abbreviated Ref. Only, if used, indicate the item is listed for reference purposes, but is not available for purchase. A Robinair part number assigned a part is five or six digit drawing number. Part numbers beginning with RA are “Replacement Assembly” numbers. These numbers depict a kit of parts or assemblies used to repair or replace certain parts of the end item. Effectivity Column (Effectivity) Reference letters (A through Z except I and 0) are assigned to the Effectivity column to each top assembly in each IPL figure. The reference letter of the applicable top assembly is also shown in the Effectivity column for each detail part and subassembly. When no reference letter is shown for detail parts and subassemblies, the item is used on all top assemblies. Parts Replacement Data The interchangeability relationship between parts is identified in the Description column of the parts list. A list of the terms used to show interchangeability and their definition is shown in the table following. 89 Downloaded from www.Manualslib.com manuals search engine P ar ts and C o m p o n e n t s PARTS LIST TERM ABBREVIATION Optional OPT Supersedes SUPSDS Superseded SUPSD BY Replaced By REPLD BY Replaces REPLS 34788 (Basic) Service Manual DEFINITION This part is interchangeable with other parts in the same Item number variant group or other item number if designated The part in the part number column replaces and is not interchangeable with the item number shown in the notation.

Technical Service Bulletin (TSB) Incorporation Except as indicated below, assemblies, subassemblies and detail parts subject to modification, deletion, addition or replacement by an issued service bulletin are annotated to show both pre and post service bulletin configuration. The term (PRE SB GGGG) in the Description column designates the original configuration, and the term (POST SB GGGG) identifies assemblies and parts after the service bulletin modification has been completed. Subassemblies and detail parts used on assemblies bearing the pre- or post-service bulletin notation will not carry the same notation themselves if the use code(s) assigned to them clearly reflect(s) their pre- or post-service bulletin status. Items Not Illustrated Items not illustrated are indicated by a (Not shown.) notation in the Description column. Alpha Variant Item Numbers Alpha variants A through Z (except I and O) are assigned to an existing item number when necessary to show: } Added items } Technical Service bulletin modifications } Configuration differences } Optional parts } Product improvement parts (non service bulletin) Alpha variant item numbers are not shown on the exploded view when the appearance and location of the alpha variant item is the same as the basic item.

BOTTLE, OIL DRAIN — Recovers the used oil during the oil drain process. BOTTLE, OIL INJECT — Stores oil for injection into the A/C system. Not used on all models. BREAKER, CIRCUIT — Protects the unit from drawing too much current. If blown, unit is completely inoperative. CALIBRATION BALL — Calibration standard that attaches to magnet under scale assembly. Used to verify scale calibration. CASTER — 5” x 2” wheels used for maneuvering unit. HIGH PRESSURE CUTOUT SWITCH — Switch opens at 435 ± 10 psi (2999 ± 69 kPa) and resets at 320 ± 20 psi (2066 ± 137 kPa). If pressure in the high side of the system exceeds 435 psi (2999 kPa), the switch opens stopping all functions. INTERNAL STORAGE VESSEL (ISV) — Storage tank where the recovered and recycled refrigerant is stored. Vapor, liquid, and air purge access is on-top of tank. KEYPAD — Touch-pad cover for the front of the control board. MANIFOLD BLOCK ASSEMBLY — Internal block assembly that contains solenoids, check valves and switches. Refrigerant will flow through the manifold assembly for proper distribution. CHECK VALVE — Allows flow in one direction only. MUFFLER, AIR EXHAUST — Disperses excessive air from the ISV. Provides effective reduction of objectionable air exhaust noise. COMPRESSOR — Moves refrigerant from the A/C system being serviced into the ISV on the unit. ORIFICE, UNION — Fitting used to reduce the flow rate. COMPRESSOR CAPACITOR — Used for starting the compressor. Helps reduce the initial high current demand required by the compressor on start-up. POWER CORD — Supplies main power to the unit. COMPRESSOR OIL SEPARATOR — Removes the compressor oil from the refrigerant leaving the compressor. New oil is returned to the compressor when the oil return solenoid receives power. PRESSURE RELIEF VALVE, 450 PSI — Spring loaded safety valve use to releases pressure from internal tank assembly if pressure exceeds 450 psi. RELAY BOARD — Relay control for all electrical components. DISPLAY/CONTROL BOARD — Front display panel and main control of the unit. SCALE ASSEMBLY — Measures the amount of refrigerant being charged and recovered. DOOR LATCH KIT — Used to replace spring-loaded latch, retainer, and door latch receptacle. SD CARD PCB ASSEMBLY — Used to read information from Secure Digital (SD) memory cards. FAN — Keeps the compressor’s electrical components cool. SIGHTGLASS – Used to view vacuum pump oil level. FILTER DRIER, SPIN-ON — Used to remove moisture and particles from refrigerant. Must be changed every time 150 lbs of refrigerant is recovered. SOLENOID (1), NORMAL DISCHARGE — When energized, allows refrigerant flow from the compressor to the system oil separator, then to the internal storage vessel. GAUGE, HIGH SIDE — Monitor high-side pressure of the vehicle being serviced. SOLENOID (2), HIGH-SIDE CLEAR — Energized during the high-side clearing process. GAUGE, LOW SIDE — Monitors low-side pressure of the vehicle being serviced. SOLENOID (3), OIL INJECT — Energized during the Oil Inject process to allow A/C system oil to be replenished. Not used on all models. HEAD ASSEMBLY — User interface panel for controlling refrigerant recovery, recycling and recharging. SOLENOID (4), DEEP RECOVER — When energized, uses vacuum pump to perform “deep” recovery of 127 Downloaded from www.Manualslib.com manuals search engine P ar ts and C o m p o n e n t s refrigerant from the system being serviced. SOLENOID (5), HIGH-SIDE CHARGE — When energized, allows refrigerant from ISV to enter highside of system being serviced. SOLENOID (6), LOW-SIDE CHARGE — When energized, allows refrigerant from ISV to enter low-side of system being serviced. SOLENOID (7), HIGH-SIDE INLET — Allows an open “pathway” for refrigerant flow and vacuum between the A/C system high side and the 34788 unit. This solenoid is powered during the Recover, Vacuum, and Leak Check process. SOLENOID (8), VACUUM — When energized, allows a vacuum or deep recovery to be pulled on the A/C system being serviced. SOLENOID (9), LOW-SIDE INLET — Allows an open “pathway” for refrigerant flow and vacuum between the A/C system low side and the unit. This solenoid is powered during the Recover, Vacuum and Flush process. SOLENOID (10), RECOVERY — When energized, provides the primary pathway of removing refrigerant from the system being serviced. This solenoid is also powered during the Flush process. 34788 (Basic) Service Manual tor to the compressor and equalizes the pressure on the high and low side of the compressor. SOLENOID (14), OIL DRAIN — Energized at the end of the Recover process to drain oil. SOLENOID (15), AIR PURGE — Energized to allow excessive air to be removed from the ISV. SWITCH ON/OFF — Allows the unit to be turned ON and OFF. SYSTEM OIL SEPARATOR — Heat exchanger with high-side coils that provide internal heat to the canister causing saturated vapor and accumulated liquid refrigerants to evaporate. This process prevents liquid refrigerant from entering the compressor and separates the refrigerant oil. TEMPERATURE PROBE — Monitors the temperature inside the ISV. TRANSDUCER, ACCUM (SYSTEM OIL SEPARATOR) — Measures the pressure within the system oil separator. TRANSDUCER, AIR PURGE — Measures the pressure within the ISV. SOLENOID (11), TANK FILL — When energized during the Tank Fill process, allows refrigerant to flow from the external supply tank to the ISV. TRANSDUCER, LOW-/HIGH-SIDE — Measures the pressure of incoming refrigerant from the A/C system. Pressure readings are then relayed to the control board. SOLENOID (12), POWER CHARGE/FEEDBACK — Provides “feedback” pressure to assist the oil drain operation. Also, increases tank pressure to assist the charging function. VACUUM PUMP — Pump designed to remove moisture and air from an A/C system. Also aids in the recovery process by performing a deep recovery of A/C system. SOLENOID (13), OIL RETURN — When energized, it returns compressor oil from the compressor oil separa- WHEEL, PNEUMATIC 10” — Transport wheels. 128 Downloaded from www.Manualslib.com manuals search engine Pa rt s and Co mp o n ents 34788 (Basic) Service Manual ALPHABETICAL PARTS LIST ALPHABETICAL PARTS LIST Description No. Qty Part No. ACCUMULATOR TRANSDUCER AGLE BALL, MANIFOLD PLUG BASE BASE ASSEMBLY BASE ASSEMBLY BEZEL (PART OF RA20001.)
