DESIGN AND OPERATING PRINCIPLE

The ventilator consists of an air duct, a ventilation unit and an outer ventilation hood. Two filters, a regenerator, a distance ring and two air flow rectifiers are installed in the air duct.
The air filters are designed to purify supply air and prevent foreign object ingress into the regenerator and the fan.
The regenerator utilises extract air heat energy to warm up supply air flow. The regenerator is heat insulated with a specially designed insulating material.
The indoor unit with the fan is installed on the inner side of the wall.
The ventilation hood must be installed on the outer side of the wall. It is used for directed air discharge and prevention of ingress of water and other objects to the ventilator.

The ventilator operates in two cycles, 60 seconds each.
CYCLE I. As warm stale extract air flows through the regenerator, which gradually absorbs heat and humidity. In 60 seconds as the regenerator gets warmed up the ventilator is switched to the supply mode.
CYCLE II. Fresh intake air from outside flows through the regenerator, absorbs accumulated moisture and is heated to a room temperature due to the heat accumulated in the regenerator. In 60 seconds as the ceramic regenerator gets cooled down, the ventilator is switched to the air exhaust mode and the cycle is renewed.

MOUNTING AND SET-UP

READ THE USER’S MANUAL BEFORE INSTALLING THE UNIT.
BEFORE INSTALLING ADDITIONAL EXTERNAL DEVICES, READ THE RELEVANT USER MANUALS

DO NOT BLOCK THE AIR DUCT OF THE INSTALLED VENTILATOR WITH DUST ACCUMULATING MATERIALS, SUCH AS CURTAINS, CLOTH SHUTTERS, ETC.
AS IT PREVENTS AIR CIRCULATION IN THE ROOM.

To install an external ventilation hood or grille, it is necessary to have access to the outer wall surface at the installation site.

1. Prepare a round core hole in the outer wall. The hole diameter depends on the specific model of the ventilator and is indicated in the table of overall dimensions in the “Technical data” section.
   

2. Install the air duct into the hole so that its cuts are aligned with the outside and inside surface of the wall. For ease of installation use the foam wedges included in the delivery.
   
   While mounting the air duct be sure to provide the minimum slope of 3 mm downwards from outside.
   The air duct can be cut by calculating preliminary the required length or after fixing the air duct on the wall (in this case, it is necessary to have access to the outside part of the wall).

3. Install the assembled regenerator and the limit ring into the air duct.
   In Solo RA1-35-9 R and Solo RA1-35-9 R V.2 models, the limit ring is connected to the regenerator.
   In Solo RA1-50-9 R V.2 and Solo RA1-60-9 R V.2 models the limit ring is inserted separately.
   

4. Use a screwdriver to unscrew the self-tapping screw from the casing and remove the front part of the indoor unit.
   

5. Attach the mounting plate and mark holes for the dowels with a pencil or marker. Drill the holes and insert the dowels. Then install the mounting plate on the wall and the rear part of the indoor unit in the duct. Fasten the rear part of the indoor unit with the screws on the mounting plate.
   

6. Install the front part of the indoor unit to its original position and fix it with a screw using a screwdriver.
   

7. Install the outer ventilation hood or the grille.

Controlling the Solo A35 S4 Pro R ventilator using a pull cord switch
The ventilator is connected to power mains using a cord with a plug with a switch on the wire. Switching from the first speed to the second is carried out only by a standard pull cord switch.

ALL THE COMPONENTS OF THE UNIT ARE ITS INTEGRAL PARTS.
MAINTAINING THE FACTORY CONFIGURATION AND FORM FACTOR IS ABSOLUTELY ESSENTIAL FOR THE PROPER AND CONSISTENT FUNCTIONING OF THE UNIT.
ANY UNAUTHORISED ALTERATIONS TO THE UNIT FORM FACTOR OR FAILURE TO ADHERE TO THE ELECTRICAL CONNECTIONS DIAGRAM SHALL RELIEVE THE MANUFACTURER FROM LIABILITY FOR ANY RESULTING MALFUNCTIONS AND VOID THE UNIT WARRANTY.

Controlling the Solo A35 S4 Pro R V.2, Solo A50 S4 Pro R V.2, Solo A60 S4 Pro R V.2 ventilator using the remote control The ventilator is connected to power mains using a cord with a plug.
The functions of the remote control buttons are shown in the figure below.
The speed at which the ventilator is currently operating is indicated by a coloured LED on the front panel of the indoor unit. The first (lower) speed corresponds to the green colour, the second (higher) speed corresponds to the blue colour of the LED.
The passage of remote control commands is confirmed by a short-term decrease in the brightness of the LED on the front panel of the indoor unit.

When switched on using the On/Off button on the remote control, the ventilator starts to operate at the speed at which it was switched off.
When switched on using buttons I or II, the ventilator starts to operate at the corresponding speed.
If the humidity sensor is switched on, then when the humidity exceeds the preset level, the ventilator switches to the second (higher) speed.
At high outdoor air humidity, the ventilator can switch to the second (higher) speed as a result of the humidity sensor triggering.
If such switching is undesirable, then temporarily turn off the humidity sensor using the remote control.
You can adjust the operating threshold of the humidity sensor by turning the potentiometer regulator using a special plastic screwdriver.

DO NOT USE A METAL SCREWDRIVER, KNIFE, ETC. FOR ADJUSTMENT OPERATIONS NOT TO DAMAGE THE CIRCUIT BOARD.

When turning on the night mode, the ventilator will operate at the first (lower) speed for 8 hours. At this time, the brightness of the LED decreases and the ventilator does not respond to speed switching and triggering of the humidity sensor. After the end of this time period, the ventilator will return to the previous operating mode. The night mode can be turned off at any time using the corresponding button on the remote control.
