1. Introduction
Congratulations on your Danfoss Nessie Plug&Spray
the best performance and service life of our product, please read this
instruction carefully and follow the recommendations how to integrate
the Plug&Spray
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.
