3. SAFETY INSTRUCTIONS AND PRECAUTIONS
Read these instructions very carefully before installing and using this equipment. Installation, connection and maintenance should be carried out
by a qualied technician and in accordance with local regulations and legislation.
The company shall take no responsibility for the injuries or damaged property if the safety requirements are not followed, or the device is modied
without the permission of the manufacturer.
Main safety rules
Danger
• Before carrying out any electrical or maintenance works, make sure that the device is disconnected from the mains and that all moving
parts of the device have stopped.
• Make sure that the fans are not accessible through air ducts or branch openings.
• If any liquids on electric parts or connections that bear voltage are noticed, stop the operation of the device.
• Do not plug the device into the mains that di󰀨er from the one indicated on the label or on the housing.
• Voltage of the mains should comply with the electrotechnical parameters indicated on the label.
• The device should be earthed in accordance with the regulations on the installation of electric devices. Turning on and using an un-
earthed device is not allowed. Follow the requirements specied on the device’s labels that indicate danger.
Warnings
• Connection of electricity and maintenance of the device should be performed by qualied personnel only and in accordance with the
manufacturer’s instructions and safety requirements.
• In order to reduce the risk during installation and maintenance, suitable protective clothing must be worn.
• Beware of sharp angles while carrying out installation and maintenance works.
• Do not touch heating elements until they haven’t cooled down.
• Some devices are heavy, you should be very careful while transporting and installing them. Use suitable lifting equipment.
• When connecting electricity to the mains, a circuit breaker of suitable size must be used.
Warning!
• If the device is installed in a cold environment, make sure that all connections and tubes are properly isolated. Intake and discharge air
ducts should be isolated in all cases.
• Openings of the ducts should be covered during transportation and installation.
• Make sure not to damage the heater when connecting the piping of the water heater. For tightening up, use a wrench/spanner.
Before starting up the device
• Make sure, that there are no strange objects inside the device;
• Manually check fans to make sure they are not stuck or blocked;
• If rotary heat exchanger is installed in the device, make sure that it is not stuck or blocked;
• Check the earthling;
• Make sure that all components and accessories are connected in accordance with the wiring diagram or provided instructions.
Danger: Fumes
Salda Antifrost system uses dis-balancing of an airow and it may cause negative pressure in premises. Care must be taken when using
the device in the premises together with another heating appliance that depends on the air in the premises. Such appliances include
gas, oil, wood or coal-red boilers and heaters, replaces, continuous ow or other water heaters, gas hobs, cookers or ovens that draw
the air in from the room and the duct-exhaust gases out through chimney or extraction ducting. The heating appliance can be starved of
oxygen, impairing combustion. In exceptional cases, harmful gases could be drawn out of the chimney or extraction ducting back into
the room. In such case we strictly recommend to turn o󰀨 Salda Antifrost and use an external preheater for heat exchanger anti-frost
protection (see Salda Antifrost function in the Remote Controller Operation Manual).

5.5. MOUNTING
• Installation works should be carried out by qualied and trained sta󰀨 only.
• When connecting air ducts, consider the labels on the casing of the unit.
• Before connecting to the air duct system, the connection openings of the ventilation unit should be closed.
• When connecting the ducts, the air-ow direction indicated on the device housing should be observed.
• Do not connect the bends close to the 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 and exhaust air ducts must be 3xD, where D is the diameter of the air duct.
• It is recommended to use brackets (accessories). This will reduce the vibration transmitted by the unit to the air duct system and environment.
• Su󰀩cient space must be provided for opening of the manhole and lter covers.
• If the ventilation unit is a wall-mounted device, it may transmit noise vibrations to the premises. Though the level of noise generated by the fans is
admissible, we recommend mounting the unit at a distance of 400 mm from the nearest wall. Where this is not possible, we recommend mounting
the unit on the wall of the room where the level of noise is not signicant.
• Ducts are connected to the unit in such a way that they could be easily disassembled,and the coil could be removed from the unit when carrying
out maintenance, service and/or repair works.
The protective lm is used to protect the unit during transportation. It is recommended to remove the lm; otherwise, oxidation
signs may occur.
The condensate tube must be lled with water as indicated during the rst start-up before every heating season!

5.7.2. DRAINAGE
• After installing the air unit, the condensate drainage system should be connected: screw up the hose (3) with the attached fastener (2) to the
condensate trap (1) of the heat recovery unit, insert the hose into the siphon (4) (shown at the bottom of the picture).
• The siphon (4) is connected with the sewage system via a pipe (5).
• It should have a gradient of at least 3° (a meter of the pipe should descend by min 55 mm)!
• Prior to starting the recovery unit, the system should be lled with 00.5 litre or more water (the siphon (4) should always be lled up) and make
sure that water goes to the sewage system)!
• Otherwise, the room may be ooded when operating the recovery unit!
• The condensate drainage system should be operated on the premises with an ambient temperature above 0 °C to prevent freezing!
• Otherwise, the drainage system must be insulated and must be provided with a heating cable and thermostat!

The condensate tube must be lled with water as indicated during the rst start-up before every heating season!
5.8. CONNECTION OF THE AIR DUCT
• The connected air ducts must not be bent and must be xed separately.
• Make sure that the fans may not be accessed through air duct heads. Otherwise, a protective grid should be installed. You may choose the grid
from the range of products provided on our website https://select.salda.lt.
• Do not reduce the diameter of the piping near the air inlet or exhaust ducts. If you want to reduce the airow speed in the system, also to reduce
pressure and noise level, you can increase the diameter.
• In order to reduce the level of noise in the air supply system, install silencers (see the chapter on air supply system installation).
• In order to reduce air loss in the system, the air ducts and prole components should be of class C or higher. The catalogue of the above-men-
tioned items can be found on our website https://select.salda.lt.
• External air and exhaust system piping should be isolated in order to prevent heat loss and condensation.
• We recommend to maintain a distance of up to 8 meters between air intake and air exhaust ducts. The air intake point should be installed away
from potential air pollution sources.
• When installing air ducts next to the ventilation equipment, brackets must be used. They suppress vibration and assure secure installation of the
various system parts. The necessary brackets can be found in our catalogue or on our website https://select.salda.lt.
• Air ducts are often mistakenly connected in an inappropriate location. The ventilation units bear the labels indicating the correct air duct connec-
tion layout. Before starting up the system, carefully check if all related works have been performed properly.
For ange diameters see chapter "DIMENSIONS AND WEIGHT".
5.9. CONNECTION OF THE UNIT TO THE ELECTRIC NETWORK
