5.5. MOUNTING

• Installation should only be performed by qualied and trained sta󰀨.

• When connecting air ducts, consider the notices indicated on the casing of the unit.

• Before connecting to the air duct system, the connection openings of ventilation unit should be closed.

• Do not connect the bends close to connection anges of the unit. The minimum distance of the straight air duct between the unit and the rst branch of the air duct in the supply air duct must be 1xD, in air exhaust duct 3xD, where D is diameter of the air duct.

• It is recommended to use the accessories-holders. This will reduce vibration transmitted by the unit to the air duct system and environment.

• Enough space must be left for opening of the maintenance door and lter covers.

• If the installed ventilation unit is adherent to the wall, it may transmit noise vibrations to the premises. Though the level of noise caused by the fans is admissible, it is recommended to mount the unit at the distance of 400 mm from the nearest wall. If it is not possible, the mounting of the unit is recommended on the wall of the room where the level of noise is not important.

• Ducts are connected to the unit in such way that they could be easily disassembled and the heater could be removed from the unit when performing service or repair works.

5.5.1. MOUNTING ON THE WALL

30 mm

a c d

Mounting on the wall:

a) To reduce the vibration stick the insulating tape on the unit‘s casing side which touches the wall before mounting the unit on the wall. b) The unit has to be mounted on the mounting brackets. c) AHU mounting drawing. d) After the unit is mounted two wall bracket tabs has to be folded to 90o angle by pliers to avoid the accident fall of the unit.

5.5.2. PLACE REQUIREMENTS FOR THE EQUIPMENT AND MOUNTING POSITIONS

1. The installation position only in the horizontal direction.

2. Install the supporting legs.

3. AmberAir Compact are assembled from separate sections.

4. They must be adjusted without a gradient.

5. Leave space in the front (2xL) that it would be su󰀩cient to open the doors and to remove or install a required component.

EN | 11SMARTY RV v2019.12

5.5.3. CONNECTION OF AIR DUCTS

• Connected air ducts must be straight and have their own xing.

• Make sure that the fans can not be accessed through air duct heads. If it is possible to access the fan, protective grid should be installed. You can choose it in our website.

• Do not reduce the diameter of the piping near air inlet or exhaust ducts. If you want to reduce the speed of air in the system, drop of pressure and noise level, you can increase the diameter.

• In order to reduce the level of the noise in the air supply system, install silencers (see chapter on their installation).

• In order to reduce air loss in the system, the air ducts and prole parts should be of class C and higher. Their catalog can be found in our

website.

• If air handling unit is installed in heated premises, outdoor and exhaust air ducts must be insulated in order to avoid heat loses and condensing. If AHU is installed outdoors, it’s recommended to insulate all the air ducts.

• It is recommended to maintain a distance of up to 8 meters between air intake and air exhaust ducts. Air supplying system should be installed further from potential air pollution sources.

• Use holders while installing air ducts next to the ventilation equipment. They suppress vibration and ensure a rm installation of various system

parts.

• Necessary holders can be found in our catalog or website.

• A common mistake is that air ducts are attached to improper airow connection. On the ventilation equipment there are signs, indicating the air

duct to be connected. Before starting the system carefully check whether the work was performed properly.

5.5.4. AIR FLOW

• Be sure the fan is disconnected from power source before performing any maintenance or repair.

• Proceed to maintenance and repair after any rotation in the fan is stopped.

• Observe sta󰀨 safety regulations during maintenance and repair.

• The motor is of heavy duty ball bearing construction. The motor is completely sealed and requires no lubrication for the life of the motor.

• Detach fan from the unit.

• Impeller should be specially checked for buil-up material or dirt which may cause an imbalance. Excessive imbalance can lead to accelerated wear on motor bearings and noise, vibration.

• Clean impeller and inner housing with mild detergent, water and damp, soft cloth.

• Do not use high pressure cleaner, abrasives, sharp instruments or caustic solvents that may scratch or damage housing and impeller.

• Do not plunge the motor into any uid while cleaning impeller.

• Make sure, that impeller ’s balance weights are not moved.

• Make sure the impeller is not hindered.

• Mount the fan back into the unit. Connect the fan to power supply source.

• If after maintenance the fan does not start or stop itself, contact the producer. Malfunction of the fan can be identied according to the pressure in the system (when pressure switches are connected). When there is a fault in fans’ motor, any separate notice is shown on the control panel.

Be sure the unit is disconnected from power source before performing any maintenance or repair.

6.5. HEATER MAINTENANCE

• Electrical heater does not need to be serviced additionally. It is compulsory to change  lters as described above.

• Heaters have 2 thermal protections: automatically self-resetting, which activates at +50°C and the manually restored, which activates at +100°C.

• After the activation of the manually restored protection, the unit must be disconnected from the power supply. Wait until the heating elements cool down and the fans stop rotating. After identifying and removing the reason of failure, to start the unit, press the “reset” button. The failure

can be identied only by a qualied professional.

• If necessary, the electric heater can be removed. Disconnect the electrical connector from the heater and remove the heater.

6.6. ROTOR MAINTENANCE

• Rotor heat exchanger must be serviced once a year.

• Ensure that the gaps of the heat exchanger are clean, the brushes are not worn, the belt drive is not worn and the clamping nodes of the rotor heat exchanger are tight.

• Rotor heat exchanger can be easily removed from the unit. The power cord of the motor of the heat exchanger is disconnected. The clamp of rotor heat exchanger section is released and raised and the heat exchanger is removed.

• The heat exchanger is cleaned using the solution of warm water and non-corrosive toward aluminum alkaline agent or the air stream. It is not recommended to apply direct stream of liquid as it can harm the device.
