UNIT DESIGN AND OPERATING PRINCIPLE The unit operation is as follows: warm polluted air is extracted from indoor to the unit and is cleaned by the extract filter. Then the air streams through the heat recovery core and is removed outside by the extract fan. The cold intake air from outside flows into the unit and is cleaned by the supply filter. Further the air flows through the heat recovery core and is supplied inside by the supply fan.

HRV/ERV 80/100/120/150 (R) (EC) (L) INSTALLATION AND SET-UP ALL OPERATIONS DESCRIBED IN THIS USER’S MANUAL MUST BE PERFORMED BY QUALIFIED PERSONNEL ONLY, PROPERLY TRAINED AND QUALIFIED TO INSTALL AND MAINTAIN VENTILATION EQUIPMENT. DO NOT ATTEMPT TO INSTALL THE PRODUCT YOURSELF. IT IS UNSAFE AND IMPOSSIBLE WITHOUT SPECIAL KNOWLEDGE. The units are designed for celling mounting. While installing the unit ensure convenient access for subsequent maintenance and repair.
EACH VENTILATION UNIT MUST BE CONNECTED TO AN INDIVIDUAL U-TRAP IRRESPECTIVELY OF THE VENTILATION UNIT TYPE Condensate drainage The HRV units must be connected to a condensate drain system. The ERV units are equipped with enthalpy recovery cores with no condensate buildup and require no condensate drain system. The drain pan in the heat recovery unit has a drain pipe to remove condensate outside of the unit.
HRV/ERV 80/100/120/150 (R) (EC) (L) CONNECTION TO POWER MAINS POWER OFF THE POWER SUPPLY PRIOR TO ANY OPERATIONS WITH THE UNIT. THE UNIT MUST BE CONNECTED TO POWER SUPPLY BY A QUALIFIED ELECTRICIAN. THE RATED ELECTRICAL PARAMETERS OF THE UNIT ARE GIVEN ON THE MANUFACTURER’S LABEL. ANY TAMPERING WITH THE INTERNAL CONNECTIONS IS PROHIBITED AND WILL VOID THE WARRANTY. The unit is for connection to the fixed installation and rated for connection to 120 V/60 Hz power supply source.
CONNECTION OF EXTERNAL CONTROLS The ventilation unit enables connection of maximum 5 controls. If any control unit is activated, the ventilation unit goes to high-speed mode. Connectable controls: 1. Remote control (thermostat). Remote control (thermostat) functions: • Unit on/off • Speed selection • Indoor temperature display • Scheduled operation 2. CO2 sensor. Recommended for use in office buildings and public premises.
HRV/ERV 80/100/120/150 (R) (EC) (L) UNIT CONTROL OPERATION MODES • Permanent low-speed mode or standby mode • High-speed mode The unit has a three-position speed switch. LOW or MED speed are used to set permanent operation mode or to set the STANDBY mode. The external controls switch the ventilation unit to the high-speed mode. The supply and extract fan speed is individually adjusted. The air capacity is controllable from 0 % up to 100 %.
In case of alarm the alarm message «Err» is displayed. To detect the alarm root, press the «KEY1» button and review the list of all alarm messages using the «KEY2» and «KEY3» buttons. The alarm message consists of a number (1, 2, 3) and a letter (n, Y). The number determines the alarm message type. 1: fire alarm activation. 2: temperature sensor short circuit 3: temperature sensor breakout The letter indicates no alarm (n) or available alarm (Y). Example: «1-Y»: fire alarm activation.
HRV/ERV 80/100/120/150 (R) (EC) (L) FREEZE PROTECTION OF THE HEAT RECOVERY CORE The freeze protection function prevents freezing of the heat recovery core in the cold season. This function is activated automatically and cannot be turned on or off. The ventilation unit periodically switches from rated operation mode to the special defrost mode (the extract fan runs in high speed, the supply fan is off ) and vice versa according to the signaling from the outdoor temperature sensor.
TECHNICAL MAINTENANCE WARNING – TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS, OBSERVE THE FOLLOWING: BEFORE REMOVING THE FILTERS, SWITCH OFF THE EXTERNAL AUTOMATIC CIRCUIT BREAKER AND LOCK THE SERVICE DISCONNECTING MEANS, THEN OPEN THE HINGED SERVICE PANEL AND REMOVE THE FILTERS CAREFULLY. IT IS POSSIBLE TO CLEAN FILTERS WITH A VACUUM CLEANER OR RINSE THEM WITH WATER AND DRY. MAKE SURE FILTERS ARE COMPLETELY DRY BEFORE THEY HAVE BEEN INSTALLED BACK INTO THE UNIT.
HRV/ERV 80/100/120/150 (R) (EC) (L) 2. Recovery core maintenance (once per year). Some dust may accumulate on the recovery core even in case of regular maintenance of the filters. Regular cleaning is required to maintain the high recovery efficiency. To clean the recovery core pull it out of the unit and clean it with a vacuum cleaner. Optionally cleaning with warm detergent solution is allowed.
Trouble The fan(s) do(es) not get started during activation of the unit. The unit does not get started, the indicator displays Err. Troubles and troubleshooting Possible reasons Troubleshooting Make sure the power supply line is connected correct. No power supply. Otherwise troubleshoot a connection error. Turn the unit off. Troubleshoot the motor jamming. Jammed motor, soiled impeller blades. Clean the blades. Restart the unit. System failure. Contact the product Seller.
HRV/ERV 80/100/120/150 (R) (EC) (L) STORAGE AND TRANSPORTATION REGULATIONS • • • • • • • Store the unit in the manufacturer’s original packaging box in a dry closed ventilated premise with temperature range from +4 ˚F (+5 ˚C) to +104 ˚F (+40 ˚C) and relative humidity up to 70 %. Storage environment must not contain aggressive vapors and chemical mixtures provoking corrosion, insulation, and sealing deformation.
