Figure 5.9.1. Drainage system 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 filled up with at least 0.5 l of water (pipe loop (3) must be always filled with water), also check if water reaches sewerage
system! In other case premise can be flooded 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 (offered as an accessory).
DRAINAGE SYSTEM INSTALLATION SMARTY 3XV/4XV F2
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

• The connected air ducts must not be bent and have separate fixing.
• Make sure that the fans can not be accessed through air duct heads. Otherwise, protective grid should be installed. You may choose the grid
from the range of products provided in our website.
• Do not reduce the diameter of the piping near air inlet or exhaust ducts. If you want to reduce the airflow speed 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 dampers (see the chapter on air supply system installation).
• In order to reduce air loss in the system, the air ducts and profile components should be of class C and higher. The catalog on the above-men-
tioned items can be found in our website.
• External air and exhaust system piping should be isolated in order to prevent heat loss and condensation.
• Maintaining the distance of up to 8 meters between air intake and air exhaust ducts is recommended. Air supplying system 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 catalog or website.
• Air ducts are often mistakenly connected in inappropriate location. The ventilation units bear the labels indicating the correct air duct connection
layout. Before starting up the system, carefully check if all related works have been performed properly.
