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 fins size, lower space between fins), optimised flow rate of heated outlet air – in effect high air exhaust temperature generated on each speed of fan.

General information

Solano heating and ventilation devices are manufactured in compliance with standards concerning quality, ecology, utility and work comfort. Solano devices are delivered ready-to-use in a cardboard package that is to protect from mechanical damages damage during transit. The package consists of: the device, wall mounting bracket, the Manual (Operation and Maintenance Documentation) and Guarantee. If the optional automatic control ordered, it shall be delivered in a separate package. Make sure all the aforementioned elements are in the package immediately after the delivery. In the absence of any element, please advise Smith’s immediately.
ATTENTION!

• 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 qualified persons with appropriate authorisations

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 difficult 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 profile. It has two holes for vertical assembly. Assembly to the wall and/or to the ceiling is possible at different angles but it requires making necessary holes in the holder.

Mounting bracket to the Solano
The bracket set consist of: a holder, two sleeves, two M8 screws and washers.
In order to mount the bracket, drill two @12-13mm holes in places visibly marked on the casing.
Insert sleeves into drilled holes and place the bracket in. The included holder must be screwed with MB screws with washers.

Installation of mounting pins
‘To mount the heater to the ceiling, use M3 mounting pins.
Drill two @8-9mm holes in places visibly marked on the casing.
Mounting pins may be screwed into the frame not deeper than 20mm.

ATTENTION!

* While drilling the holes in marked places be careful not to damage the coil by going deeper than 20mm!

Assembly cf Solane MIX air mixer
To mount Solano MIX aar maxer to the ceding, use MB mounting pans. Oril two @8-9men holes in places vsibly marked on the casing.
Mounting pins may be screwed into the frame of a heat exchanger to the maximum depth of 20mm. Mounting pans and connecting elements are not included with the unit.
NOTICE!

• To sustain proper functioning of the device keep a safe distance – 200 mm from its sides and 300 mm from its backside to the fan

Electrical installation

The electrical installation and connection to power supply must be done in compliance with the existing regulations and standards for building industry.
The fan’s engine is equipped with the internal temperature limit fuse protecting the engine from its overheating.
The unit set does not consist of: a feeding cable, a master switch (see diagram)
The electrical installation must be done by an authorised person, acquainted with the Manual. The connection of the feeding cable and master switch must be done in compliance with electnical diagram (with or without the automatic control, depending on the option chosen). Any and all damages incurred as a result of the aforementioned causes are not provided with the Guarantee and the user will be charged with any costs of the device exchange. The connection of the automatic control should be carried out in accordance with the electrical diagram.
In case of any doubts or problems, unplug the device and contact the device’s installer or Smith’s Authorised Service.

Water installation

The installation of the unit should be done in a way enabling maintenance service; on both stub pipes manual closing valves should be installed in order to cut off the device. Feeding cables of the heater shall be connected in accordance with the symbols/marking on the casing (inlet/outlet). In case of electromagnetic valve (with the option of the automatic control) it should be installed on the outlet as it may be damaged otherwise. When the pipework is being connected to the exchanger, secure the connections of the heater from oscillating torque (see figure) that may cause leakage in the exchanger.

Heating medium
The connector pipes are at the back of the device.
When connecting the hydraulic pipes/connections, make sure you secure the connector pipes against rotational torque.
Notice that the connector pipes are not strained by the pipes.
The valve of heating medium is on the supply pipe and the vent is on the return pipe.

Use flexible connections to allow the heater to be turned to the sides. Depending on the flexible connections, the maximum turn is 70° – for Solano Eco MAX, 78° – for Solano Eco 1, 2 and 3 to both sides. Figure shows maximum angle to one side and 50° to the other with minimal distance left for connections.

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)

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.

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.

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/fixing does not work loose contact the installer or Smith’s Authorised Service

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 fin due to high possibility of damaging them. If fins are bent use a tool specifically 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.
