1.2 Machine Description and Intended Use

This machine is a hydronic air heater. The Wacker Neuson Hydronic Air Heaters

consist of trailer-mounted enclosures that house a hydronic heater, electric motors,

fixed pump(s) and plumbing, a diesel burner, a fuel tank, and a hose handling

system.

The hydronic heating system utilizes a burner that indirectly warms the HTF. The

warmed HTF is continuously circulated through a vented, closed loop hose system.

A centrifugal pump pushes the warmed HTF through heat exchangers via hoses.

The heat exchangers transfer the heat from the HTF into the air of the application

area. A low HTF level protection device shuts down the machine if the HTF level

drops below minimum operational capacity.

This machine is intended to be used as an air heater. In addition, when used with

other Wacker Neuson accessories, this machine can be used to thaw frozen

ground, cure concrete, or prevent frost and freezing. An insulated blanket may be

laid over the hoses to increase efficiency.

This machine has been designed and built strictly for the intended use(s) described

above. Using the machine for any other purpose could permanently damage the

machine or seriously injure the operator or other persons in the area. Machine

damage caused by misuse is not covered under warranty.

The following are some examples of misuse:

 Using the machine to heat anything other than what is stated above

 Using the machine to pump anything other than the factory recommended heat

transfer fluid

 Using the machine as a ladder, support, or work surface

 Using the machine to carry or transport passengers or equipment

 Using the machine to tow other machines

 Operating the machine outside of factory specifications

 Operating the machine in a manner inconsistent with all warnings found on the

machine and in the Operator’s Manual

This machine has been designed and built in accordance with the latest global

safety standards. It has been carefully engineered to eliminate hazards as far as

practicable and to increase operator safety through protective guards and labeling.

However, some risks may remain even after protective measures have been taken.

They are called residual risks. On this machine, they may include exposure to:

 Heat, noise, and exhaust from the engine or hydronic heater

 Burns from HTF or radiant heat from the hoses

 Fire hazards from improper refueling techniques

 Fuel and its fumes

 Personal injury from improper lifting of the trailer tongue

 Tripping hazards from the hoses

To protect yourself and others, make sure you thoroughly read and understand the

safety information presented in this manual before operating the machine.
