CHAPTER 6

SERVICE AND MAINTENANCE

The following sections are included to illustrate the proper procedure for servicing and maintaining the AccuFlow 

system. This chapter also includes instructions for disassembling the AccuFlow Vortex cooler for cleaning and 
storage.

DISCHARGING THE ACCUFLOW™ SYSTEM

The AccuFlow system must be discharged of all anhydrous ammonia and the system must be completely shut 

down before the implement can be transported.

The following procedure outlines the proper method for discharging NH

3

 from the AccuFlow system and 

preparing the system for transport, service, or maintenance.

NOTE:

Personal protective equipment such as a respirator, goggles, face shield, clothing that fully covers 

bare skin, protective suit, and gloves are required when working with anhydrous ammonia products.

NOTE:

Refer to Figure 1 and table on page 63 when referencing component locations for discharging the 

Accuflow System.

 

DANGER

Anhydrous ammonia can cause severe burning, 

blindness, or death. Refer to 

Discharging the 

AccuFlow™ System

 section on page 5 opage 61 

and follow the procedure for bleeding the 

AccuFlow system before beginning maintenance.

 

DANGER

DO NOT transport the AccuFlow system while it 

is charged with anhydrous ammonia. The 

AccuFlow Vortex cooler and product lines must 

be completely discharged before transporting 

the implement.

 

DANGER

Use extreme caution when opening a previously 

pressurized system. Exposure to anhydrous 

ammonia can cause severe burning, blindness, or 

death. To avoid injury or death, always wear 

proper personal protective equipment.
