Do not tamper with or replace parts of the unit without the specific consent of the manufacturer. These interventions re
-
lease the manufacturer from any civil or legal responsibility.
Using components, consumables or spare parts that do not correspond to those recommended by the manufacturer and/or
listed in this manual may be dangerous for the operators and/or damage the unit.
The operator’s workplace has to be kept clean, tidy and clear of objects that may hinder free movement. Appropriate
lighting of the work place shall be provided so as to allow the operator to carry out the required operations safely. Poor or
excessive lighting can cause risks.
Ensure that work places are always adequately ventilated and that the extraction systems are working, in good condition
and in compliance with the requirements of the laws in force.
In the design phase, the indications contained in UNI EN ISO 14738 regarding workstations on the machinery were followed
and the lifting limits imposed by UNI ISO 11228-1 were evaluated.
Make sure to maintain, during the installation and maintenance of the unit, a posture that does not cause fatigue. Check the
weight, before moving any component.
The unit works with R32 refrigerant, which is included in the list of greenhouse gases (GWP 675) which are subject to the requirements in EU
regulation n. 517/2014 called “F-GAS” (mandatory in the European zone). Among the provisions of this regulation, it sets forth that operators
working on systems running with greenhouse gases be in possession of a certification, issued or acknowledged by the competent authorities,
attesting that they have passed a test authorising them to perform this work. In particular
•
Up to 3kg total refrigerant in the appliance: category 2 certification.
•
3 kg e and more total refrigerant in the appliance: category 1 certification.
The gaseous form of R32 refrigerant is heavier than air and if released into the environment, most of it tends to concentrate in poorly ventilated
areas. Inhaling it can cause dizziness and sensations of suffocation and can develop lethal gas if in contact with naked flames or hot objects (see
the refrigerant’s safety data sheet).
Pay attention to the fact that refrigerant fluids can be odourless
For any operation on the heat pump system:
Wear the appropriate PPE (specifically gloves and goggles).
Make sure that the workplace is well ventilated. Do not work in closed environments or ditches with little air circulation.
Do not operate on the refrigerant in the vicinity of hot parts or naked flames.
Do not release the refrigerant into the environment and pay special attention to accidental leakage from pipes and/or fit
-
tings even after having emptied the plant.
Make sure there is a fire extinguisher near the unit.
