What Is An Evapco Cooling Tower Manual​

An EVAPCO cooling tower manual usually refers to the Installation, Operation & Maintenance (IOM / O&M) Manual that is model-specific. EVAPCO does not publish one single universal manual—each tower type has its own.

Below is how EVAPCO manuals are structured, where to get the correct one, and what each section covers.

1. Common EVAPCO cooling tower manuals (by model)

EVAPCO manuals are issued by tower family, for example:

* AT Series – Induced draft counterflow cooling towers

* LST / LSTE Series – Low sound cooling towers

* ATWB Series – Closed circuit cooling towers

* Eco-AT / Eco-LST – Evapco eco cooling towers

* Forced Draft Towers

* Plume Abatement Towers

⚠️ Using the wrong manual can lead to incorrect oil, fan pitch, or startup procedure.

2. What an EVAPCO cooling tower manual includes

A standard EVAPCO O&M manual contains:

A. Installation

* Foundation & anchoring requirements

* Rigging and lifting instructions

* Piping connections & basin layout

* Electrical motor wiring

* Vibration switch installation

B. Startup procedure

* Pre-start inspection checklist

* Fan rotation check

* Gearbox oil verification

* Initial water chemistry guidelines

* First 24-hour inspection

C. Operation

* Normal operating limits

* Fan cycling and VFD operation

* Cold-weather operation

* Shutdown procedures

 D. Maintenance

* Daily / monthly / annual maintenance

* Fan blade pitch settings

3. How to get the correct EVAPCO manual

You will need one of the following:

1. EVAPCO model number (e.g. AT-19-821)

2. Serial number (on tower nameplate)

3. Order number (if available)

Official sources

* EVAPCO local representative

* EVAPCO Aftermarket / Service department

* EVAPCO customer portal (for registered owners)

OEM manuals are usually provided free in PDF for existing equipment.

4. Important notes (very common mistakes)

❌ Using Marley oil recommendations on EVAPCO gearboxes

❌ Copying fan pitch settings from another tower

❌ Ignoring EVAPCO cold-weather basin protection guidance

❌ Skipping first 500-hour gearbox oil change
