02 Product description
iZZi 300 ERV is an air handling unit with heat recovery
intended to ensure safe, balanced, energy-ecient and
comfort ventilation in the residential buildings. For mechanical
ventilation with heat recovery a vitiated air with odour, e.g. from
the kitchen, bathroom, WC is extracted and the same amount of
fresh air is supplied to, among others, a living room, bedroom
and children's room.
A countercurrent membrane heat and moisture exchanger
(enthalpy heat exchanger), recovering both moisture and heat
from the extracted air, is used for heat recovery in iZZI 300 ERV.
It is recommended to use humidity sensors to monitor limit
value in the rooms where the humidity level is high.
Use of enthalpy heat exchanger ensures that it is not necessary
to connect the condensate outlet to the equipment. Lack
of condensate outdropping on the heat exchanger allows
its operation also during negative temperatures outside the
building. Therefore it is not equipped with a built-in preheater.
The compact housing is made of stainless steel sheet and has
universal mounting system: under the ceiling, on the wall or on
the floor. internal cladding is made of high-quality polyethylene
foam and ensures required thermal and noise insulation. iZZi
300 ERV recuperator has two service-free energy-ecient
direct current fans (EC) ensuring high available compression.
Standard equipment includes also built-in 100% automatic
bypass of heat exchanger. The unit is factory equipped with two
pleated filters, class M5 (ePM10 75%)

02.01.1 Rating plate
The rating plate is located on the upper wall of the housing,
next to electrical service lines (figure above). It is used for
identification of the product. The information contained herein
is needed for safe use of the product and service purposes. The
nameplate should not be covered or removed from the unit.

02.02 Recuperator operation method.
The equipment has been designed and manufactured as a unit intended for ventilation of the residential rooms with areas up to 100m
and allows maximum air exchange approx. 300 m of the air per hour. The recuperator should be selected not only for the area of the
given room, but also considering air exchange demands.

OUTDOOR AIR

EXTRACT AIR
EXHAUST AIR
EXHAUST: used up air is exhausted from the rooms, that is kitchen, toiler or bathroom through AIR EXHAUST
EXHAUST VENT: air cooled down in the exchanger is extracted outside via EXHAUST VENT
INTAKE VENT: fresh air drawn from outside by a duct marked as INTAKE VENT is directed to heat exchanger
AIR SUPPLY: supplied air from outside, heated in heat exchanger is supplied to the rooms by the AIR SUPPLY
02.03 Bypass
The built-in automatic bypass allows used air to be discharged to the outside without a heat exchanger, so that heat is not released to
the supplied air. Such a solution allows using free-cooling phenomena during the summer. The bypass settings are described in item
08.07.5.
02.04 Enthalpy heat exchanger
The device is equipped with a counter-current enthalpy heat exchanger with a polymer membrane. Air removed from the building
gives the thermal energy and moisture back to the fresh air stream supplied to the building, without mixing. The membrane of heat
exchanger separates two air streams and have a thin, dense polymer barrier layer, allowing absorption of the water vapors and
penetration through it. At the same time, it blocks gases, volatile organic compounds and other pollutants. The material of the heat
exchanger ensures its high durability.

02.05 Freeze protection system
Freeze protection system protects heat exchanger against frost formation at low external temperatures. The use of specially designed
enthalpy heat exchanger, recovering the moisture in the iZZi 300 ERB recuperator, this phenomena can occur only during the very high
frosts, when the outdoor temperature drops below approx. minus 7°C. In such a case, the heat exchanger defrosting mode is activated
periodically. It is based on automatic lowering of speed of the air supply fan and activation of optional duct preheater (if connected).

05 Planning
05.01 Methods of assembly
Use of enthalpy heat exchanger, which does not the require
discharge of condensate, allows distinguishing four methods of
recuperator foundation:
05.01.1 Vertical, on the floor
Note: additional height increases on your own.
05.01.2 Horizontal, on the floor
05.01.3 On the wall
Assembly on the wall should be carried out using a special frame
from a scope of delivery (1)
05.01.4 On a ceiling
Assembly on the wall should be carried out using a special frame
from a scope of delivery (1)
05.02 Requirements for the assembly location
The iZZi 300 ERV recuperator is intended for assembly in the
rooms where the temperature does not fall below 5°C, and
relative humidity does not exceed 70%.
The prepared substrate should ensure even and stable adhesion
of the recuperator. For proper operation, the manufacturer
recommends mounting on a solid wall/ceiling or, in the absence
of such surface, on a suitably reinforced surface which does not
transmit any vibrations.
05.03 Electric connection
Electrical service lines 230V with grounding (plug socket)
should be prepared in a maximum distance of 2.5 metres from
conductor's outlet from the recuperator.
05.04 Control panel
The enclosed control panel allows flush-mounting or wall-
mounting (using the enclosed dedicated mounting box) -
according to the drawings below. Factory supplied cable of the
controller has 3 metres.

05.05 Safe area
When planning the space for the installation of the
recuperator, please consider the appropriate free
and easily accessible space in front of and above the
recuperator for service and operation purposes.
* minimum distance required for filters replacement
requires disassembly of the front cover of the
recuperator (see item 09.02)
05.06 Anti-smog filter box - option
If additional filter box is used then it is necessary to plan additional space near the recuperator (from the side of air intake vent or air
supply to the rooms).
