VENTO A50 / A50-1 / A50 S / A50-1 S
We are happy to offer your attention a new high-quality single-room
reversible unit with heat and humidity recovery
VENTO A50 / VENTO A50-1
.
The solid team of high-qualified professionals with many years of working
experience, technological innovations in design and production, high-
quality components and materials from the top worldwide producers have
become the precondition for the best energy saving unit in its class.
INTRODUCTION
The present operation manual contains technical description, technical
data sheets, operation and mounting guidelines, safety precautions and
warnings for safe and correct operation of the unit.
GENERAL
The single-room unit is designed for efficient energy saving supply and
exhaust ventilation of flats, houses, cottages and other small premises.
The heat recovery technology is used to minimize ventilation heat losses.
The unit is equipped with a high-tech ceramic heat accumulator
(regenerator) that provides utilization of extract air heat energy for warming
up of filtered supply air flow. The heat regeneration efficiency is up to 91%.
The unit is designed for indoor application with the ambient temperature
ranging from -20 °C up to +50 °C and relative humidity up to 80%.
The unit is designed for external through-the-wall installation.
The unit is designed for continuous operation always connected to power
mains.
The unit is allowed for operation only after final mounting, that includes
installation of protecting devices in compliance with DIN EN ISO 13875 (DIN
EN OSI 12100) as well as other construction safety equipment.
The unit design is regularly improved, so some models may slightly differ
from those ones described in this operation manual.
SAFETY RULES
The unit complies with the requirements according to the EU norms
and directives, to the relevant EU-Low Voltage Equipment Directives, EU-
Directives on Electromagnetic Compatibility.
All operations related to the electrical connection of the unit, like servicing
and repair works are allowed only after the disconnection from power mains.
All mounting and servicing operations are allowed for duly qualified
electricians with valid electrical work permit for electric operations at the
units up to 1000 V after careful study of the present operation manual.
The unit must be grounded!
Please follow the safety regulations and working instructions (DIN EN 50
110, IEC 364).
Make sure the impeller and the casing are not damaged before
connecting the unit to power mains. The casing internals must be free of any
foreign objects which can damage the impeller blades.
Disconnect the unit from power mains prior to any operations related to
the unit servicing and repair works.
Misuse of the unit or any unauthorized modification are not allowed.
The unit is designed for connection to AC single-phase power mains, see
the Technical Data. The unit is rated for permanent operation during non-
stop power supply.
Take steps to prevent ingress of smoke, carbon monoxide and other
combustion products into the room through open chimney flues or other
fire-protection devices. Sufficient air supply must be provided for proper
combustion and exhaust of gases through the chimney of fuel burning
equipment to prevent back drafting. The maximum permitted pressure
difference per living units is 4 Pa.
The transported air must not contain any dust or other solid impurities,
sticky substances or fibrous materials.
The unit is not designed for use in an inflammable and explosive medium.
Do not close or block the unit intake or exhaust vent not to disturb the
normal air passage.
Do not sit on the unit and do not put objects on the unit.
In case of unusual sounds, smoke disconnect the unit from power supply
and contact the service centre.
Follow the manual guidelines to ensure trouble-free operation and long
service life of the product.
Hazardous parts access and water ingress protection standard IP24.
STORAGE AND TRANSPORTATION RULES
Transportation of the unit is allowed by any vehicle provided the unit is
transported in the original package and is protected against weather and
mechanical damages.
Use hoist machinery for handling and transportation to prevent possible
mechanical damages of the unit. Fulfil the requirements for transportation of
the specified cargo type during cargo-handling operations.
Store the unit in a dry and cool place in the original packing.
The storage environment must not be subjected to any aggressive and/
or chemical evaporations, admixtures, foreign objects that may provoke
corrosion and damage connection tightness.
Store the unit in an environment with minimized risk of mechanical
damages, temperature and humidity fluctuations.
Do not expose the unit to the temperatures below +10°C and above +40 °C .
Connection of the unit to power mains is allowed after the unit has been
kept indoor for minimum two hours.
