Sullair ES-6, 24KT Technical Manual – 78 Pages of Factory Specs

If you’re wrenching on a Sullair ES-6 or 24KT compressor, you don’t need theory. You need the exact lubricant spec, the torque for the separator cover, and the right sequence to bleed the system. This Technical Manual is the factory document – 78 pages of OEM instructions in Spanish. No aftermarket rewrite, no missing pages, no “close enough” numbers. I’ve seen guys try to service a 24KT with a generic compressor manual. That’s how you cook a separator. This manual gives you the actual fluid viscosity, the exact pressure settings for the control system, and the torque values for critical fasteners. It’s the same binder the dealer techs pull off the shelf.

Safety First: 10 Sections You Skip at Your Own Risk

Chapter 1 is all safety: pressure release, hot surfaces, moving parts, electrical hazards. Page 1 covers the mandatory PPE and lockout procedures. If you’ve ever had a 200-psi line whip loose or a fan blade catch a sleeve, you’ll respect those pages. The manual covers everything from Liberación de la Presión (pressure release) to Personas Encerradas (confined-space entry). Don’t skip section 1.3 – that’s the procedure to safely vent the system before pulling a filter. I tag that page in every manual I hand to a helper.

What’s Inside the Sullair ES-6, 24KT Technical Manual?

Seven chapters, each built for a specific job. Chapter 2 (Descripción) walks through the integrated compressor, cooling system, air intake, control system, and all the gauges. Chapter 3 (Características) gives the technical specs for the ES-6 and the dedicated 24KT lubrication guide – that’s where you’ll find the approved fluids and change intervals. Chapter 4 (Instalación) covers location, ventilation, piping, fluid level checks, motor rotation, and electrical prep. Chapter 5 (Funcionamiento) is the startup and shutdown sequence – first start, subsequent starts, and emergency stop. Chapter 6 (Mantenimiento) is the thickest section: daily use, motor bearing lubrication, fluid filter maintenance, cooler cleaning, and detailed procedures for replacing the separator cartridge, adjusting the control system, calibrating the pressure switch differential, and servicing the discharge solenoid. The troubleshooting guide in 6.7 is worth the price alone – it lists fifteen common faults and the corrective actions. Chapter 7 has the illustrations and parts lists – 18 exploded-view diagrams covering the fluid control system, intake filter, shaft seal, motor, cooler, compressor assembly, admission control, electrical cabinet, and wiring schematics for star-delta, single-phase, and dual-voltage setups.

7 Major Systems Covered

Here’s what you get: (1) Safety systems and interlocks, (2) Fluid control – standard and 24KT, (3) Air intake and filtration, (4) Cooling system, (5) Control system with pressure switches and solenoid valves, (6) Electrical power and motor control, (7) Separator and condensate management. Each system has its own chapter or subsection. Need the wiring diagram for a 200-230V single-phase motor? That’s in Chapter 7. The Esquema Eléctrico Doble Mando sections show you the exact wire colors and terminal numbers. No guessing.

Get the Right Torque Data from the Parts List

Every bolt that matters shows up in the parts diagrams with a reference number. Then you cross-reference that number to the torque spec table – if it’s not printed on the diagram itself, it’s in the maintenance procedure. For example, the separator cover bolts: the manual tells you the tightening sequence and torque in foot-pounds. Copy that into your log book. The fluid filter housing also gets a specific torque – overtighten it and you crack the plastic, undertighten and you get a leak. The manual doesn’t leave room for interpretation.

Lubrication Guide: 24KT vs Standard Fluid

Section 3.2 covers the standard compressor lubricant; section 3.3 is exclusively for the 24KT system. The 24KT uses a special fluid that requires different change intervals and viscosity checks. Running standard oil in a 24KT voids the warranty and will score the rotors. The manual lists the Guía de Lubricación with ambient temperature ranges and recommended oils. It also explains the optional fluid alternatives in 3.4. I keep a copy of that page in my service truck.

FAQ

Is this manual in English?

No. It is the original Spanish OEM document.

Can I use this to service a 24KT compressor?

Yes. The manual includes a dedicated lubrication guide for 24KT fluid, separator replacement steps, and control system adjustments. Unlike aftermarket PDFs, this is scans of the original factory booklet – every torque spec came from Sullair’s engineering. You’ll find the 24KT-specific lubricant change procedure in Chapter 3, and the maintenance intervals in Chapter 6. If you’re troubleshooting a 24KT that’s overheating or losing pressure, the fault-finding guide on page 24 walks you through five common failure modes. This is the same binder the dealer techs used.

For a deeper look at rotary screw compressor operation, the Manual Transmission analogy can help understand gear ratios, and the Manual Transmission basics cover clutch engagement – both apply to understanding compressor drive train loads. But when it comes to the Sullair ES-6 and 24KT, stick to this factory Technical Manual. Access the Factory Manual now and keep it on your shop tablet or print it for the binder. You’ll reach for it every time a pressure switch acts up or a separator needs changing.
