Product Overview Features 1. Fresh air function This product is provided with two AC high static pressure forward centrifugal fans. One brings fresh oxygen-enriched air to the room, and the other one discharges stale air from the room. 2. Air purification function This product adopts the high efficiency and low resistance filter of a world famous brand. 3.
Use Conditions 1. Outdoor air conditions The temperature range is –10°C to 40°C and the relative humidity is 85% or lower. If the temperature is lower than –10°C, it is recommended to configure a pre-heating function section separately. 2. Indoor air conditions The temperature range is 0°C to 40°C, and the relative humidity is 85% or lower. 3. Installation requirement It is the same as the indoor environment (the indoor environment here is the environment in an air conditioned living room).
For any exception or failure occurring during the operation, contact the technical service center. Do not try to operate or repair device by yourself. During normal operation, make sure that nobody can touch the live parts of the machine and the operating unit. If the device drops or is hit violently, please contact our service center immediately.

Controller Basic model - double control switch 1) Power-on/off OFF: Power off the unit ON: Power on the unit 2) Fan speed regulation LOW: The unit operates at the low speed HIGH: The unit operates at the high speed Upgraded version - LCD controller 1) Power-on/off Press to start the unit. Press again to shut down the unit. 2) Fan speed regulation Press ▲ and ▼ to stop the fan or make the fan operate at the low speed or high speed.
"1023" indicates the filter has worked for 1,023 hours. Hold down for more than 5s to reset the work duration of the filter. High configuration version - Intelligent controller 1) Power-on/off Press to start the unit. Press again to shut down the unit. 2) Fan speed regulation Press ▲ and ▼ to stop the fan or make the fan operate at the low speed or high speed.
change the value. Press again to switch to PM2.5 concentration setting. The position displaying the CO2 and PM2.5 concentration originally will display the set value and blink. Press ▲ and ▼ to change the value. If no keystroke operation is performed within 10s, the controller automatically saves the settings and returns to the normal operating state. 5) Filter reset After startup, hold down for 5s to set the work duration threshold for the filter.
Installation General instructions The user should entrust professional HVAC engineers with engineering design and engage an experienced company with construction qualifications to complete engineering construction. Design and construction should be implemented according to the relevant codes and regulations of the state. Otherwise, the unit may fail to work normally. For the after-sales service of this unit, TICA will charge a fee..
Note: Note to prevent gases from flowing back to the room. Preparations before installation 1. Unpack the unit before installation, and check whether the unit appearance is in good condition and whether unit is not deformed. Check whether accessories are complete according to the packing list. For any problems found, contact the local distributor immediately. 2. Prepare connection wires according to the electrical principle diagram, route the wires through sleeves, and bury them in the wall.
Installation 1. Follow instructions in this operation manual to install the product. Refer to the figure below. Return air pipeline Lifting bolt Fresh air pipe insulation material RA (return air) Pipe cover SA (supply air) OA (outdoor fresh air) Thermal insulation material for Air supply discharge duct grille EA (discharge air) Return air grille Figure 3 Installation reference diagram 2.
3. Install the ducts. Use elbow as less as possible in the pipeline, and design the bending part of the elbow in an arc shape (90° right angle bending should be avoided). See Figure 5.
and the return air inlet is far, or the air outlet is far and the return air inlet is near. The interval between the discharge air outlet and the fresh air outlet should be about 2 m, preventing stale indoor air from returning to the room.

Electrical Installation 1. Wire layout Install the wires according to the national standard; The power cord should be fixed reliably lest the connecting terminal would be stressed. Do not pull the power cord forcibly; The 1.5 mm2 wire harness is recommended for the power cord.
1. Running water pipe; 2. gas pipe; 3. sewage pipe; 4. other unreliable places in the point of professionals' view. Warning: Before installing and maintaining the system, cut off the power supply to prevent the motor from damaging people. Configure wires according to the requirements. Otherwise, the unit may fail and electric shock or fire may occur. Special Notice TICA will not bear any responsibility for the outcomes resulting from reconstructing the electric control system without prior permission.
Operation and Maintenance Check the connection line after the installation work is completed, and make sure to perform trial operation. Check before trial operation 1. Pipeline system check Check whether the duct direction is correct, whether the equipment suspension is firm, and whether the hanging bracket is coated with antirust paint; check whether sundries or installation tools are left behind in and on the duct and equipment; check whether the air outlet is installed firmly. 2.
Observe the air inlet/outlet status of each indoor/outdoor air port. If the air flow and direction of the indoor air port can be adjusted, adjust it to a proper status. Carefully check whether there is any abnormal noise in the ventilation system, and observe whether the screws at the joints of all parts get loose and whether the sealing effect of sealing strip is good. If no exception is found when the machine operates, it can be used normally.
Removing and installing related parts falls into the scope of maintenance operations and must be completed by professionals. Cleaning and replacing the filter The ventilator (heat recovery fresh air handling unit) contains one air filter. It is recommended to check it every one to two months, or determine the replacement cycle independently according to the power-on time or the decrease degree of air flow. Replace the filter every three to six months according to the air pollution (dust, smog, etc.
