The installation and initial start-up of the appliance must be performed by qualified personnel in compliance with the national regulations in force regarding installation, and in conformity with any regulations issued by local authorities and public health bodies. The water heater is supplied with a sufficient amount of R134a refrigerant for its operation. This refrigerant fluid does not damage the atmosphere’s ozone layer, is not flammable and does not cause explosions; however any maintenance activities or work on the refrigerant circuit must exclusively be carried out by authorised personnel with the suitable equipment. 3.2 Implementing the instructions WARNING! Incorrect installation can harm persons or animals and damage possessions; the manufacturer shall not be held liable for any damage in such cases. The installer is required to observe the instructions outlined in this manual. Once installation is complete, it is the installer’s duty to inform and instruct the user on how to operate the water heater and carry out the main operations correctly. 3.3 Safety regulations Refer to Paragraph 1.1 under the section GENERAL INFORMATION for the description of the symbols used in the table below.

INSTALLATION WARNING! Observe the general warnings and safety instructions listed in the previous paragraphs and strictly adhere to the indications therein contained. 4.1 Location of the appliance WARNING! Prior to starting any installation activities, ensure that the location where the water heater is to be installed satisfies the following requirements: a) In the event of water heaters without an air exhaust duct, the room of installation should have a volume of no less than 30 m 3 and must be adequately ventilated. Avoid installing the appliance in rooms which may favour frost build-up. Do not install the product in a room containing an appliance that requires air to function (e.g. an open-chamber gas boiler, open-chamber gas water heater, etc.) unless otherwise indicated by local law. The product’s safety and performance levels are not guaranteed in the event of outdoor installation. b) The appliance’s air exhaust and/or extraction duct (if present) must have access to the outside from the point where the appliance is installed. The connections for the air exhaust and aspiration ducts are located on the upper part of the appliance; c) Ensure that the installation site and the electrical and hydraulic systems to which the appliance must be connected fully comply with the regulations in force; d) The chosen site must have, or must be suitable to house, a single-phase 220-240 V ~ 50 Hz power supply socket; e) The chosen site must be suitable to house a condensate drainage outlet connected to the lateral of the appliance with a suitable siphon; f) The chosen site must ensure that the appropriate safety distances from the ceiling (par. 4.3) and wall (below pictures) can be observed. It is suggested have the distance shown in first picture.The second picture shown the main distances that allow the right operational functions and guarantee the main component maintenance. They do not allow the fan replacement, in this case it will be necessary move the product. g) that installation of the ducts allows maintenance operations on the evaporator filter (refer to par. 4.3); h) that the plan allows a perfectly vertical operating position; i) The chosen site must conform to the appliance’s IP protection rating (protection against the penetration of liquids) as specified by the regulations in force; j) The appliance must not be exposed to direct sunlight, even when windows are present; k) The appliance must not be exposed to particularly aggressive substances such as acidic vapours, dust or gas-filled environments; l) The appliance must be installed as close as possible to the points of use to limit heat dispersion along the piping; m) The air aspirated by the product must be free of dust, acicid vapours and solvents. 4.2 Positioning on the ground 1) Once the suitable installation position has been located, remove the packaging and remove the fixings visible on the pallet where the product is based. 2) Using the appropriate belt, remove the product from the pallet. 3) Fix the feet on the ground (through the appropriate holes) using suitable screws and rawlplugs; after positioning the appliance, remove the fabric belt by loosening the relative bolts.
