Air handling unit SMARTY 3X VE with plate heat exchanger (temperature efciency up to 90 %) is designed to clean and supply fresh air. The unit
takes heat from exhausted air and transmits it to supply air.
MAIN FEATURES
Air ow ranges:
• Building protection 60 m³/h;
• Minimal 95 m³/h;
• Nominal 233 m³/h
• Maximal 333 m³/h
• Counter ow heat exchanger is made from aluminum and has the following dimensions: (WxHxD) 271 x 496 x 350 mm. Spacing between the plates
is 2 mm;
• Efcient and silent EC fans - type R3G190RC05-03 Sound Power Level LW 45 dB(A) (ISO 9614-2 or ISO3744);
• Low SFP (Specic Fan Power) level: ≤ 0.35 W/(h/m³);
• Housing is made of galvanized steel. Outer side of the housing - white powder coating - RAL 9016. Inner corners of the body separating the air ows
are sealed with a sealant material.
• 30mm acoustic and thermal mineral wool insulation of external walls; to maintain low leakage level the doors are covered by special sealing material
from foam.
• Integrated control automation, Plug & Play function;
• SMARTY 3X VE can be controlled with FLEX or Stouch control panels;
• Filter type corresponds to the requirements of LST EN 779:2013:
Extract – panel M5 (WxHxD) 435 x 175 x 25 mm
Supply – panel F7 (WxHxD) 435 x 175 x 25 mm
• Outdoor exploitation temperature +5 °C to +40 °C.
Not suitable for swimming pools, saunas and other similar facilities.
• All units are packed in the factory to withstand regular conditions of transportation.
• The unit can be lifted using metal rods (Pic. 1). Rod diameter - 35 - 40 mm.
• 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 relative 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.

- Do not use the unit for purposes other than its’ intended.
- Do not disassemble or modify the unit in any way which may lead to mechanical failure or injury.
- Use special clothing and be careful while performing maintenance and repair jobs – the unit’s and its components’ edges may be sharp and cutting.
- Do not wear loose clothing that could be entangled in to operating unit.
- Do not place ngers or other foreign objects through inlet or exhaust guards or into connected duct. If a foreign object enters the unit, immediately disconnect
power source. Before removing object, make sure that any mechanical motion has stopped, the heater has cooled down and the restart is not possible.
- Do not connect to any other power source than indicated on the model label.
- Do not place or operate unit on unsteady surfaces and mounting frames.
- Mount the unit rmly to ensure safe operating.
- Never use this unit in any explosive or aggressive elements containing environment.
- Do not use the unit if external connections are broken or damaged. If there are any defects, stop operating the unit and replace the damaged parts
immediately. That can be performed only by qualied electrician.
- Do not use water or another liquid to clean electrical parts or connections.
- If you notice water on electrical parts or connections, stop operating the unit.
• 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).

Unplug unit from mains before opening the door (disconnect 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.).
Dirt increases air resistance in the lter, therefore less air
is supplied into the premises.
It is recommended to change the lters
every 3-4 months, or in accordance to lter
timer.
• Maintenance should be performed only by experienced and trained staff.
• 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 staff 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 vibration.
• Clean impeller and inside 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 identied according to the pressure in the
system (when pressure switches are connected). When there is a folt in fans’ motor, any separate notice is shown on the control panel.
After changing the lters reset the lter ti-
mer on the control panel. How to that is des-
cribed in 13 (24 p.) paragraph.

• Proceed to maintenance and repair after any rotation in the fan stopped.
• Clean the heat exchanger once a year.
• Firstly take out heat exchanger cassette carefully. Submerge it into a bath and wash with warm soapy water (do not use soda). Then rinse it with
weak hot water stream (too strong stream can fold the plates). Place back the heat exchanger only when it is completely dry.
