1. Overall information
Solano heating and ventilation devices are designed to be applied in the buildings of small and medium capacity, such as: production
and warehouse halls, car showrooms and service stations, sports halls and stadiums, sacral buildings and churches, retail stores
and wholesales outlets, agricultural facilities and exhibition halls. Solano provides a dedicated solution for connection to low water
temperature sources (for example condensing boilers and industrial heat pumps). Main advantages of Solano are: high temperature
of outlet air is generated by low temperature of water supplied to a unit, maximum use of the heating coil surface - new geometry of
coil construction (enhanced ns size, lower space between ns), optimised ow rate of heated outlet air - in effect high air exhaust
temperature generated on each speed of fan.

• Before mounting read the manual carefully and adhere to the rules concerning the mounting procedures. Failure to do so, may
result in inappropriate functioning of the device and the loss of the guarantee rights.
• Pay special attention when working with electrical elements of the device.
• Any installation operations must be carried out by qualied persons with appropriate authorisations
4. Assembly
Prior to any installation procedures, take the following aspects into consideration: easy access for maintenance works, access to water
and electrical installation, appropriate air distribution in a room.
Each Solano unit is equipped with a set of 2 interchangeable colour inserts; in order to change the colour, remove the insert from the
front panel and place the desired one back in place.
It is advisable to mount the device to the wall or the ceiling on original mounting brackets, supporting mount pins (not delivered
with the device) or supporting constructions (shapes and dimensions of the supporting construction may be individually designed in
compliance with durability and strength requirements).
In case of mounting to the ceiling, pay attention to the fact that air-release/venting of the device may be difcult so it is advisable to
place vent at the highest point of the pipework.
The device may be mounted to the wall with the use of a mounting bracket at the angle of 0°, 30° or 60 °. A mounting bracket holder
is made of curved prole. It has two holes for vertical assembly. Assembly to the wall and/or to the ceiling is possible at different angles

7. Automatic control - installation
A set of automatic control may be used (powered 230V) that consists of the following:
• COMFORT panel - including room thermostat and switch for regulation of 3 speeds of fan. One COMFORT panel may regulate up to
3 pcs of Solano Eco 1, 2 and 3 units or 2 pcs of Solano Eco MAX
• 2-way water valve with actuator; valve should be installed on a return stub of the heater
• INTELLIGENT electronic control panel with an automatic speed controller, weekly program and BMS communication.
One INTELLIGENT panel may regulate up to 2 pcs of Solano Eco units or for single Solano Eco MAX
• Splitter MULTI 6 - control up to 6 pcs of Solano Eco, Solano Eco MAX units from one COMFORT or INTELLIGENT Panel
The system is ready to start once the connections between the thermostat and the valve actuator are done, 230V power is supplied to
the thermostat and the fan’s motor is powered by the revs controller.
COMFORT panel description
ON/OFF - turning ON/OFF a unit
I-II-III - switch for fan speed regulation
HEAT - thermostat sends signal for valve and actuator and fan, fan turns off when temperature in
room is achieved, valve/actuator closes water supply.
FAN - function not active, unit will not operate when FAN switch is selected
COOL - thermostat sends signal only to fan and to the servo of the valve, fan begins operation
starting from temperature which is set on thermostat (function used to air mixer Solano MIX or for
room ventilation in summer season)
8. First start
Do all the connections (electrical, water and automatic control), check for tightness of all connections done by an installer and
air-release/vent the device then start the device in the following sequence:
1. Switch on the mains,
2. Set requested speed of fan on revs controller,
3. Set requested temperature on thermostat,
The fan operates continuously irrespective of whether the heater’s valve is opened or not.
9. Turning off
To switch the device off do the following:
1. Set minimum temperature on thermostat - after 7 seconds valve will be closed and heating switched off.
2. Set main switch to the “0” position (off); fan will be switched off and the thermostat will be off the power.
10. Operation
The engine and fan used in Solano Eco and Eco MAX units are maintenance-free devices but regular check-ups are advised, especially
motor and bearing (fan’s rotor should rotate freely, free from any axial and radial throws and undesired knocks/rattles).
NOTICE!
• In case of any metallic knocks, vibration or increase in sound level check if the fan mounting/xing does not work loose contact
the installer or Smith’s Authorised Service
11. Maintenance
The heat exchanger requires systematical cleaning all with all dirt/impurities cleaned off. Before the start of the heating period the heat
ex-changer is advised to be cleaned with compressed air directed to the air outlets; there is no need for dismantling of the device. Pay
special attention when cleaning the exchanger’s n due to high possibility of damaging them. If ns are bent use a tool specically
designated to carry out such repairs. If the device has not been used for a longer period of time, unplug it before the next use.
The heat exchanger is not equipped with any frost protection device. The heat exchanger may be damaged if the room temperature
goes below 0°C.
Anti-freeze liquid must be added to the water circulation/system. Anti-freeze liquid must be appropriate for the material the exchanger
is made of (copper) as well as other elements of the hydraulic system. The liquid must be diluted with water according to the solution
recommended by the anti-freeze manufacturer.

One COMFORT panel may regulate up to:
• 3 pcs of Solano Eco 1, 2 or 3
• 2 pcs of Solano MAX
* The unit set does not consist of: a master switch, a fuse, a feeding cable
HEAT - thermostat sends signal for valve/actuator and fan, fan turns off when temperature in room is achieved, valve/actuator closes
water supply.
FAN - function not active, unit will not operate when FAN switch is selected
COOL - thermostat sends signal only to fan and the servo of the valve, fan begins operation starting from temperature which is set on
thermostat (function used to air mixer Solano MIX or for room ventilation in summer season)
Attention! You can use additional jumper on the contacts 4-5 of COMFORT Panel, in this case you may only use function of changing
speed of fan I-II-III and ON/OFF. The thermostat and switches HEAT/FAN/COOL remain not active.
Additional jumper on terminals 4-5 might be applied when for ex different (supplied by user) thermostat is used to control the system.
In that case:
- motor would be working on set speed
- thermostat open/close the servo of the valve depending on set temperature
