• Voltage of the mains should comply with the electrotechnical parameters indicated on the label.
• The device should be earthed in accordance with the rules of installation of electric appliances. It is forbidden to turn on and use un-
earthed device. Follow the requirements of the device’s labels that indicate Danger.
Warnings
• Connection of electricity and maintenance of the device should be performed only by a qualied personnel, in accordance with the
manufacturer’s instructions and valid safety requirements.
• In order to reduce the risk during installation and maintenance, suitable protective clothes should be worn.
• Beware of sharp angles while performing installation and maintenance tasks.
• Do not touch heating elements until they haven’t cooled down.
• Some devices are heavy, thus one should be very careful while transporting and installing. Use suitable lifting equipment.
• While connecting electricity to the mains a circuit breaker of suitable size is necessary.
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.

Danger: Fumes
Salda Antifrost system uses dis-balancing of the air ow and it may cause negative pressure in premises. Great care should be taken
when using at the same time in premises as another heating appliance what depend on the air in 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 which
draw air in from the room and duct exhaust gases out through a 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 this case we strictly recommend to turn o󰀨 Salda Antifrost and use an external preheater for heat exchanger anti-frost
protection (see Salda Antifrost function on the Remote controller manual).

5.5. MOUNTING
• Installation should only be performed by qualied and trained sta󰀨.
• When connecting air ducts, consider the labels on the casing of the unit.
• Before connecting to the air duct system, the connection openings of ventilation unit should be closed.
• When connecting the ducts , you should pay attention to the air ow direction indicated on the device housing.
• 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 attached to a 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 per-
forming service or repair works
The protective lm is intended to protect the unit during transportation. It is recommended to remove the lm because other-
wise oxidation signs may occur.
Before every heating season the condensate tube shall be lled with water as indicated during the rst startup!

DRAINAGE INSTALLATION SMARTY 2XV
øD
Figure 5.9.1. drainage installation (øD=150 mm)
It’s required to connect condensate drainage system after hanging or placing of air handling unit. Insert condensate draining into AHU. Condensate
draining must be lubricated with a sealant (I-VII) and connected to a condensate removal system.
Remove the sticker on the bottom of the unit, which covers a drainage hole. Then open the unit cover (II) and take out the heat exchanger. Put
condensate outlet pipe to EPP casing through intended hole (V), use silicon gasket (IV). Place from the bottom side gasket and screw a brass nut
on (VII). Screw the nut by holding the pipe with a hand in order prevent spinning (it’s possible to hold with a screwdriver or 1 Euro coin by putting
it in the notch on the pipe). Screw the nut with a wrench (No. 27) until a top part presses in the EPP casing (level with a surface or slightly enters
into it). Attention: Screwing force may not exceed 2 Nm.
Pipe (3) (metal pipe should be connected with G3/8 elbow, plastic pipe – with G3/8 elbow or rubber hose – with strap if the unit is placed on the
legs, in other cases condensate hose can be connected in any direction) should be connected by following order: AHU (1), pipe (2), and drainage
system. Pipes (3) should be bended not less than 3° degrees (1 meter of pipe must be bended 60 mm downwards)! Before turning on AHU (1) the
draining system should be lled up with at least 0.5 l of water (pipe loop (3) must be always lled with water), also check if water reaches sewerage
system! In other case premise can be ooded during AHU operation!
Draining system must be installed in the premise where the temperature is not lower than 1°C. If temperature falls below 0°C the draining system
should be isolated with thermal isolation. The pipe loop 2) not necessarily must be mounted below the AHU (1), but below the AHU (1) level.
Note. If the collector is situated upstream, install a system with a condensate pump (o󰀨ered as an accessory).
DRAINAGE INSTALLATION SMARTY 3XV/4XV
1.Connect the drain couplings (ZPGGM056) part A (G ½ male) to drainage connection into the unit, by turning it clockwise by hand. Do not use
any tools (I-III)!
2. Connect drain couplings part B(G ½ male) to condensate syphon or looped sanitary hose(IV-V).
3.Connect drain couplings A and B parts. Hold back the part A with the key during connection (VI).
5.10. CONNECTION OF THE AIR DUCT
D2 dimensions depend on unit.
• Connected air ducts must be straight and have their own xing.
• Make sure that the fans can not be entered through air duct heads. If it is possible to enter 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

EN | 13SMARTY XV v2020.2
and noise level, you can increase the diameter.
• In order to reduce the level of the noise in the air supply system, install dampers (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.
• Outside air and exhaust system piping should be isolated in order to prevent heat loss and condensation.
• 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 assure 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 connected in inappropriate place. 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.
Right side connection Left side connection
5.11. CONNECTION OF THE UNIT TO ELECTRIC NETWORK
• Supply voltage to the unit must be connected by a qualied specialist following the manufacturer’s instructions and e󰀨ective safety instructions.
• The unit’s power network voltage must correspond to electrotechnical parameters of the unit indicated in the technical decal.
• The unit’s voltage, power and other technical parameters are provided in the unit’s technical decal (on the unit casing). The unit must be connect-
ed to the voltage plug socket of the grounded power network in compliance with the e󰀨ective requirements.
• The unit must be earthed according to the rules on installing electrical equipment.
• It is prohibited to use extension wires (cables) and power network plug socket distribution devices.
• Prior to carrying out any ventilation unit installation and connection activities (until its hand-over to the customer), the unit must be disconnected
from the power network.
