and is not designed for independent operation.
The unit is designed to provide permanent controlled air exchange by mechanical
ventilation in houses, oces, hotels, cafés, conference halls and other residential and public premises
as well as utilization of extract air heat energy to warm up supply puried air.
The unit is for ceiling mounting.
The unit is rated for continuous operation always connected to power mains.
Operating medium must not contain any ammable or explosive mixtures, evaporation of
chemicals, coarse dust, soot and oil particles, sticky substances, brous materials, pathogens or any
other harmful substances.
The unit is not designed to be used by children, physically or mentally
disabled persons, persons with sensory disorder, persons with no appropriate
experience or expertise.

TECHNICAL DATA
SAFETY REQUIREMENTS
While operating and mounting unit fulll the requirements of the present operation manual
as well as general requirements of all applicable codes and standards valid in USA and Canada.
Ground the unit!
Before connecting the unit to power mains make sure that the unit is free of any visible
damages or any other foreign objects inside the casing that can damage the impeller blades.
Connection of the unit to power mains by duly qualied and authorized electricians only!
Do not!
• Do not operate the unit beyond the specied temperature range or in an aggressive
and explosive medium.
• Do not connect clothes dryers or similar equipment to the ventilation system.
• Do not operate the unit in the air and dust mixture environment.
Warning!
Mounting, servicing, connection and repair works of the unit are allowed after
the unit is disconnected from power mains.
The unit is designed for indoor application with the ambient temperature ranging from
+34 °F (1 °С) up to +122 °F (50 °С).
Ingress Protection rating:
IP44 for the unit motors.
IP 22 for the assembled unit connected to air ducts.
The unit net weight is 66 lbs (30 kg).
The unit series designation, basic overall and connecting dimensions are shown in fig. 1.
The unit design is regularly being improved, so some models can slightly dier from those
ones described in this manual.

STRUCTURE AND OPERATING LOGIC
The unit has the following operating logic (g. 2):
Warm stale extract air from the room ows through the air ducts to the unit, is puried
in the extract lter and is supplied to the heat recovery core and exhausted outside by exhaust fan.
Clean cold air from outside is moved by supply fans to the unit where it is puried through the supply
lter. Then clean air ows through the heat recovery core and is supplied to the room by supply fan.
Thermal energy of warm extract air is transferred to clean intake fresh air and warms it up.
The extract and intake air ows are fully separated during heat recovery which excludes any transfer
of odors and pathogens to supply air. Heat recovery minimizes thermal energy losses, energy demand
and heating costs.

Fig. 3. Ceiling unit mounting example
While mounting the unit provide enough access for the unit maintenance and servicing.
Mount the unit to ceiling with threaded rods xed inside the dowels attached to the ceiling or
by means of the belts that are rigidly xed to horizontal plane (g. 3). The unit can be installed on
mounting supports with adjustable height for connection to the drain system (g. 4).

min 4”

8Brig HRV 120 (170)
To attain the best performance of the unit while mounting provide a straight 20’’
(500 mm) duct section in front and behind the unit. The unit must be equipped with a grille with the
mesh width up to 1/2” or any other protecting device to prevent free access to the unit fans.
CONDENSATE DRAINAGE
The unit is equipped with a condensate drain hose for condensate drainage (g. 5).
Connect the drain hose (1), U-trap (3) and drain system (5) with metal, plastic or rubber pipes (2 and 4).
The pipes must be sloped down at least by 3°. Before starting operation of the unit ll the system with
water and check that U-trap is always lled with water. Make sure that the water drainage is correct,
otherwise some condensate may be accumulated inside the unit and provoke subsequent equipment
damage and water ingress to the room. The condensate drainage system is designed for operation at
the ambient temperature above 32 ºF(0 °С). If the ambient temperature is below 32 ºF(0 °С), insulate
the drain system and provide air heating.

Connection to power mains
Cut power supply o before any operations with the unit. The unit shall be
connected to power mains by a duly qualied electrician only. Rated values of the
electrical parameters are shown on the rating plate. Any modications of the internal
connections are not allowed and will void the warranty.
The unit is designed for connection to single-phase ac 120 V / 60 Hz power mains.
The unit is equipped with a power cable and a plug and can be connected to any standard
grounded outlet. The power cable is connected to the terminal X1 by default.
Connect the unit to power mains through the external automatic switch integrated into the
xed wiring system that breaks the circuit in case of short circuit or overload.
Install the circuit breaker to have a free quick access in case of need to turn the unit o
promptly.
The unit has overload protection provided by the thermal fuse which is activated in case of
overload or short circuit. To replace the thermal fuse, disconnect the unit from power mains, remove the
overload or short circuit. Remove the thermal fuse and check the unit.
Wiring diagram is shown in g. 6.
The thermostat TS1 (g. 6) provides freezing protection of the unit during cold season.
As the thermostat is activated, the supply fan stops and the heat recovery core is warmed up with extract
air stream. To adjust the thermostatic switch, rotate the control dial to required setpoint. The setpoint
depends on the operating conditions. Recommended setting of the thermostat is 37°F (+3ºС), set in the
factory by default.

UNIT CONTROL
The unit is controlled by a three-position speed switch that enables low-speed modes «Low»
and «Med» as well as «Stand by» mode which enables total air quality control (g. 7).
Up to ve external control devices may be connected to the terminals 2-11 that turn the unit
to high-speed ventilation in case of activation of any of the control devices (g. 7).
