Microcool Bighorn - Starting the System

System Preparation for Startup

Includes system flush, checking water/drain valves, and turning on power to the module.

Pump Operation Initiation

Steps for starting the pump, VFD speed increase, and confirming pump is running.

Pressurizing the System

Install Drain Valves

Install automatic drain valves or plugs into open ends of atomization lines, using Teflon tape on NPT threads.

MAN;OFF;AUTO Switch and Regulator

Select AUTO for external controllers; MAN for manual. Do not adjust the pressure regulator.

Change oil after first 50 hours, then every 500 hours. Recommended: 75w-90 gear oil.

Inlet Water Filter Maintenance

Inspect filter cartridge regularly; change at least annually or when outlet gauge shows pressure drop.

Guidelines for Location and Installation of Atomization Line

Installation Environment and Supports

Covers airflow, supports, nozzle angle/direction, ceilings, hot surfaces, and line drainage.

Line Routing and Drainage Details

Guidelines for venting, twists/kinks, support/routing, and ensuring proper drainage gradients.

Installation of Flexible Atomization & Manifold Line Fittings

Use of Reusable Hose Fittings

Use Teflon tape on male threads for liquid-tight seals, but NOT on the stem component of reusable fittings.

Installation of Reusable Hose Fittings

Assembly Tools and Steps

Detailed steps for assembling reusable hose fittings using tools, ferrules, stems, and silicone.
