1. Introduction

Congratulations on your Danfoss Nessie Plug&Spray

TM

 unit. To ensure 

the best performance and service life of our product, please read this 

instruction carefully and follow the recommendations how to integrate 

the Plug&Spray

TM

 unit into your system.

2. General performance

The Nessie high-pressure water products from Danfoss are designed 

to operate on clean tap or potable water and technical water with 

low conductivity (De-Mineralized, De-Ionized, Reverse Osmosis). 

Danfoss defines clean tap water as water filtered to 10 µm absolute, 

β value > than 5000. This means that the water is filtered to a level 

where 99.995% of all particles larger than10 µm have been filtered out. 

Since Nessie pumps are water lubricated and cooled, failing to meet 

the water quality specification will reduce the expected service life 

of the components and void the limited warranty. It should be noted 

that systems with high-pressure atomization nozzles require a high 

filtration degree of the water to ensure optimal performance of the 

spray nozzles.

It is the responsibility of the end-user to provide sufficient feed water.

The system must be properly bled of air to prevent the pump from 

cavitating and running dry. Improper bleeding will cause cavitation 

and damage the pump (see chapter on commissioning).

Danfoss Nessie products are manufactured to operate properly at 

water temperatures of 3°C to 50°C (37°F to 122°F). Operation outside 

this area may cause damage to the system.

The Plug&Spray

TM

 unit must be operated within the specifications 

stated in this manual. Sustained operation of components above the 

recommended limits will cause excessive wear and shorter service life.
