2. ASSEMBLY
2.1. Required exploitation conditions
The unit and ducts should be assembled in rooms with temperature 5°C - 30C and heat-separated
form surroundings.
Not following above conditions will cause liquefaction of condensate and cumulate it inside and outside
of the unit which may cause dampness in the room or damage to the unit.
2.2. Pre-assembly requirements
While planning the assembly of the unit consider:
- ensuring the expliotation conditions of the unit
- possibility of bringing about ventilation pipes to the device
- possibility of siphonning of steam condensate
- possility of bringing about electric energy
- easy access to maintenance and repairs
2
WARNING!
1. Ventilation installation and other belonging elements must be in accordance with Polish Norms
referring to ventilation in residential and public utility buildings.
2. The unit is not destined for drying the unseasoned houses.
3. In case of damage to elements arising from not following the above instructions,
they will be not repaired under warranty.
4. Due to design reasons there is a possibility of mixing the air inside the unit with amount
not exceeding 2%.
Prior to connecting the unit check elements condition, including casing and wiring. In order to avoid any damage,
the unit should be kept in safe place in original packaging.
2.3. Unit location
The unit is destined for assembly under dry roofed rooms with basements (attics, utility room).
The unit should be assembled in a way to allow free drain condensate from the tub.
WARNING!
Manufacturer does not include assembly elements with the unit. Buyer should purchase elements separately.
After unit is placed, it shoud be leveled. It has an essential meaning for proper work of the condensate
drainage system.

rev:12.07.17
2.4. Assembly of condensaation dreinage system
Steam condensation can be observed during unit's work. It is completely normal and it is not an abnormality
in working. In order to siphon out condensate the unit is equipped with stub pipe placed on the right side.
It is essental to properly connect the pipe siphoning out the condensate.
Exemplary way of conneting the pipe is shown below. The pipe should have adequate diameter to the stub-
pipe (1/2"). It shoud be bent into letter "U" and suffused with water until stabilizing its level.
Shipon should be palced around 150 mm from the unit and radius should not be less than R=30 mm.
Given measures should be taken as minimal.

Inner stub-pipes diameters are 198mm and are fitted to standard Termoflex ducts 200 mm.
Ventilation ducts should be assembled carefully with the use of OZ duct clip (4 pcs).
In case of assembly in temparature below 12°C and above 32°C it is recommended to insulate ventilation
ducts with mineral wool of min. thickenss 30 mm. Such operation will assure efficient work
of the ventilation system.

- may results in injuries!)
8. Turn off the unit using control panel
9. Unplug power cord from grid
10. Disconnect control panel from unit
11. Mount the unit in ventilation system
12. Lead control panel's cord from unit to destined mounting place
13. Mount control panel
14. Connect unit to control panel

Properly mounted Optimal does not require any special maintenance during use. Maintenance is the
replacement of air filters. Visual indication informs about filter replacement.
3.4. Usage and maintenance
Filter exchaange in steps:
1. Disconnect connection cord from power grid
2. Disconnect control panel from the unit
3. Dismount the casing by unscrewing butterfly screws
4. Carefully take out used filters and replace with new ones
5. Mount back the casing and screw with butterfly screws
6. Connect power cord and control panel
7. Connect unit to power grid
8. Reset the timer
WARNING!!!
Unit should not work without filters. It is only recommended for testing, but no longer than 10 minutes.

3.5. Summer mode
During unit's work heat recovery is only needed to temperature of around 18°C. Cold recovery is neecessary
in ventilated rooms if temperature is above 26°C. When outter temperature is between 15-26°C
it is required to use by-pass, which results in ommision of warming the air. For this purpose Optimal 400 by-
pass/600 b-pass ar equipped with automatic by-pass.
The moment when by-pass is opened hear exchange does not take place. By-pass is used for cooling
ventilated rooms with the use of cool air for example from GWC.
Switch, presented on the picture below in position By-Pass Manual means opening the actuator.
It closes when outter temperature falls below 10℃. Switching to By-Pass Auto means automated work
of actuator.

3.6. Working with carbon monoxide sensor (option)
OPTIMAL unit is designed to work with carbon monoxide sensor. Basic function of this sensor it detection
of carbon monoxide and generating alarm when excessive amount of it is detected. Sensor decreases
risk of carbon monoxide poisoning and allows to take action in life-threatening situations.
Carnon monoxide sensor should be installed in:
- room with fireplace or tiled stove
- room with gas burners
- bathroom with warm water gas heaters
- boiler house
- garage or workshops
Unit working with carbon monoxide sensor results in exhaust and intake fans to work on maximum
speed. Decrease of carbon monoxide in air allows unit to return to normal operation mode.
Detailed description of carbon monoxide sensor can be found in manual.

źNecessity of filter replacement is signaled by countdown timer via visual warning.
The filter cartridge made of polyester fabrics cannot be cleaned and must be replaced with a new one if
necessary. New filters should be ordered from the device supplier.
The time indicator of contamination of the filter counts down the time remaining until the next filter
change.
To start the countdown for the first time, press and hold the RESET button for 3 seconds.
The need to replace the filter is signaled by audible and visual signals - after the countdown is over, the digits
00 00 00 are displayed on the screen.
The signal must be reset by pressing the RESET button.
The device is equipped with a magnet and CR1130 battery.
Fan check-up
Despite of required maintenance work (cleaninf/filer exchange) dust and grase can be slowly embed inside
the fan, which can decrese its effecitivity. Fan can be cleand with cloth or soft brush. Keep caution while
cleaning not to damage fan's impeller. Do not clean with water, do not put in water! Solid dirt can be cleaned
with denaturated alcohol. Prior to placing back - dry well.
Control of condensate's stub-pipe
Stub-pipe can become dirty overtime by fixed particles brought by air. It is recommended to periodically
check (by flushing with water) stub-pipe patency. Clean if needed.
ź
ź
4. Exploitation Recommendation
ź
Unit is a part of a whole system. the system supplies fresh air and launches used air through ducts
and intake/exhaust diffusers. Air diffusers are installed in ceilings, walls, bathrooms and rooms.
They should be periodically cleaned with warm water and soap, if needed. If they were dismounted
for cleaning they should be put in the same places - they cannot be changed.
źControl of fresh air inlet and launcher
Pollution as leafs, insects, dust, etc.) can clog air inlet which causes air flow throttling.
Check and clean air inlet at least twice a year.
Launcher installed on wall must be checked (cleaned if needed) at least once a year.
źDuct check-up (every 5 years)
Dust and grease particles will pile up in duct despite of recommended maintenance which can decrease
effectivity of installation. Due to that fact, ducts should be cleaned/exchanged when needed.
Cleaning intake and exhaust

ź5. Electrical connection - automation module
Optimal unit has a separated automation module, in which electrical connections are led.
For service purposes the module can be demounted as whole and examined on separate service desk.
1. Disconnect connection cord from power grid
2. Disconnect panel control's connection cord from automation module
3. Dismount the casing by unscrewing butterfly screws
4. Unscew screws holding module inside the unit (6 pcs)
5. Remove module from the casing
6. Disconnect fans, temperature sensor and bypass
Assembly is performed in reversed order. Once performed start unit.
Connections in automation module are carried in accordance with scheme attached to this document.
WARNING!!!
Disassembled module can be connected by authorized person on prepared test stand only.
Module is equipped with elements under 230VAC which can cause damage to health when carried out by
unqualified person.

WARNING:
Electric equipment is not a household waste. Once exploitation time is over it should be disassembled
by hand with use of wrench, screwdrivers and pliers). Electric motors, automation, power supply,
steel elements and those made out of plastics should be recycled. Information where to recycle is available
at local administration offices.
