HRV/ERV H 120(170)
CONNECTION TO POWER MAINS
CUT POWER SUPPLY OFF BEFORE ANY OPERATIONS WITH THE UNIT.
THE UNIT SHALL BE CONNECTED TO POWER MAINS BY A DULY QUALIFIED
ELECTRICIAN ONLY.
RATED VALUES OF THE ELECTRICAL PARAMETERS ARE SHOWN ON
THE RATING PLATE. ANY MODIFICATIONS OF THE INTERNAL CONNECTIONS
ARE NOT ALLOWED AND WILL VOID THE WARRANTY.
CONDENSATE DRAINAGE
The unit is equipped with a condensate drain hose for condensate drainage (fig. 5), (applicable only for HRV H 120(170). 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 fill the system with water and check that U-trap is always filled 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.

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 fixed 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 off 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 fig. 6.
The thermostat TS1 (fig. 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.
