1.1 - Introduction
Prior to the initial start-up of the NXHP units, the
people involved should be thoroughly familiar with
these instructions and technical data for the
installation.
The instaler must conduct his own risk analysis
before starting the installation of this unit.
The NXHP outdoor systems are designed to
provide a very high level of safety and reliability
making installation, start-up, operation and
maintenance easier and more secure. They will
provide safe and reliable service when operated
within their application range.
They are designed for an operating life of 15 years
by assuming a 75% utilisation factor; that is
approximately 100,000 operating hours.
The procedures in this manual are arranged in
the sequence required for machine installation,
start-up, operation and maintenance.
Be sure you understand and follow the procedures
and safety precautions contained in the instructions
supplied with the machine, as well as those listed
in this guide, such as: protective clothing such as
gloves, safety glasses, safety shoes and
appropriate tools, and suitable qualifications
(electrical, air conditioning, local legislation).

refrigerant with domestic propane. In the event
of a leak, refrigerant and air mixture may form a
flammable atmosphere. Any ignition source, such
as open flamme, hot surfaces (Above 370°C) or
any device potentially source of electric arc
(sockets, electrical switches, static discharge, ...)
must be kept at least one meter distance from
the unit.
Take protective measures to prevent all
electrostatic discharges.
