• All units are packed in the factory to withstand regular conditions of transportation.
• Upon unpacking, check the unit for any damages caused during transportation. It is forbidden to install damaged units!!!
• The package is only for protection purpose!
While unloading and storing the units, use suitable lifting equipment to avoid damages and injuries. Do not lift units by holding on power supply cables,
connection boxes, air extract or exhaust anges. Avoid hits and shock overloads. Before installation units must be stored in a dry room with the rela-
tive air humidity not exceeding 70% (at +20 °C) and with the average ambient temperature ranging between +5 °C and +30 °C. The place of storage
must be protected against dirt and water.
• The units must be transported to the storage or installation site using forklifts.
• The storage is not recommended for a period longer than one year. In case of storage longer than one year, before the installation it is necessary
to verify whether the bearings of fans and motor rotate easily (turn the impeller by hand) and if the electric circuit insulation is not damaged or the
moisture is accumulated.

Unplug unit from mains before opening the door (discon-
nect the power plug from the outlet or if there is a two-pole
automatic circuit breaker installed – disconnect it as well.
It is necessary to ensure that it won’t be turned on by third
parties) and wait until the full stop of the fans (for about 2
min.).
Changing lters, lters reload timer control. Description
of remote control panel functions is provided in the remote
control panel technical documentation or on the website
www.salda.lt.
Allowed to operate the unit without lters!
It is recommended to change the lters every 3-4
months, or in accordance to lter timer.
Smarty 2R VE Smarty 2R VE plus
Dirt increases air resistance in the lter, therefore less air is supplied into the premises.
Taking o󰀨 the lters:
• Open cover.
• Remove the lter.
• Use lters of M5 panel lter for Smarty 2R VE / pocket ler for Smarty 2R VE plus.
• Unit is designed to operate only indoors.
• It is forbidden to use the unit in potentially explosive environment.
• Unit is designed to supply/extract only clean air (free of chemical compounds causing metal corrosion, of substances aggressive to zinc, plastic and
rubber, and of particles of solid, adhesive and bred materials).
Outdoor air - temperature min./max.* [°C] -20 / +40
- humidity [%] 90 Extract air - temperature min./max.* [°C] +15 / +40 - max. humidity [%] 60
* Can be used at temperatures below -20 °C with pre-heater, the power of which is over 600W.

• Maintenance should be performed only by experienced and trained sta󰀨.
• The fan should be inspected and cleaned at least once a year.
• 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.

• 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.

• The maintenance side can be changed for the ventilation unit, i.e. it can be mounted with the left ambient air inlet or the right ambient air inlet. That
can be implemented by switching over the back door and the front door. The default version of the ventilation unit is right.

• 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 recom-
mended to apply direct stream of liquid as it can harm the device.
• While cleaning, protect the motor of heat exchanger from entry of moisture and uids.
• After reinstalling the heat exchanger, fasten the heat exchanger section with the clamp. Connect the heat exchanger motor.
CAUTION: the heat exchanger can not be used when
the lters are removed!

• 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 recom-
mended 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.
