1 • Professional product
The RENSON®Endura Delta is a balanced ventilation system with heat recovery. The unit
mechanically brings fresh air into the home and mechanically extracts “polluted” air from the
home using two integrated fans.
The RENSON®Endura Delta is a professional product and must therefore be installed by a
qualified installer.
• This manual has two parts: one for the installer and one for the user.
• This installation manual contains all of the necessary information on installation, problem-
solving, and maintenance. Please read through this manual carefully before connecting or
servicing the unit.
• The user manual contains all the necessary information on using the unit, easy maintenance,
and what to do in case of error messages.
2 • Materials, packaging and the environment
Ensure that the packaging materials are disposed of in an environmentally friendly
manner after taking the unit out of the packaging. By recycling the packaging, the
use of raw materials is lessened and the waste mountain is reduced.
Disposing of the unit
Old electrical and electronic appliances often contain materials that are still valuable.
However, they also contain hazardous materials, which are necessary for the
operation and safety of the appliance. You must therefore never dispose of a
discarded appliance with the regular waste.
Please dispose of the appliance in an environmentally friendly manner, by taking it
to the appropriate recycling centre.
3 • General regulations and safety regulations
The appliance in this packaging complies with the applicable CE safety requirements.
• The Endura Delta complies with the legal requirements that are applicable to electric
appliances.
• Exposure to radio waves.
If you equip the Endura Delta with air quality sensors (slave) that communicate wirelessly with a
Master TouchDisplay, the data is sent via a high-frequency transmitter and receiver.

3.1 • General instructions
• Always comply with the safety regulations, warnings, remarks, and instructions in the manual.
Non-compliance with these safety regulations, warnings, remarks, and instructions can result in
damage to the unit or personal injury, and RENSON®NV cannot be held liable for this.
• The installation of the Endura Delta must be done in accordance with the generally and locally
applicable construction, safety, and installation regulations laid down by the municipality and
other bodies.
3.2 • Transport
• The necessary caution should be taken during transport and unpacking of the unit. Avoid
severe jostling of the unit during transport and handling. When transporting using a forklift, the
unit must be secured to the pallet at all times.
• The front panel of the unit is tempered glass. So you must exercise caution when transporting
and installing the unit. The packaging has been adapted in such a way that the unit can be
transported under normal conditions without being damaged.
• Transport and store the unit in the upright position. The unit may never be transported on its
side due to the glass front panel.

3.3 • Setup and installation
• This unit is intended for indoor use, in a domestic setting. If there is a deviation in the setup,
please contact RENSON®.
• Only recognised RENSON®installers may install, connect, start-up, and service the Endura
Delta for maintenance, unless otherwise stipulated in the user manual.
• The Endura Delta may NOT be placed in rooms where the following are present or could
occur:
− Excessively greasy atmosphere;
− Corrosive or flammable gases, liquids, or vapours;
− Room temperatures above 40°C or under 2°C (the Endura Delta must be installed in a frost-
free location!);
− Relative humidity above 90%, or installed outdoors.
• The unit, plus related components and controls, may not be used in locations where they could
potentially be exposed to jets of water.
• All cabling must be done by a qualified person.
• Ensure that the power supply is 230 V, single phase, 50 Hz.
• When installing the unit, take the conformity with the noise requirements according to the
applicable standard (Belgium: NBN S01-400-1, Section 8) into account.
• In order to bring in fresh air and extract “polluted” air, the supply and discharge of outdoor/
indoor air must take place through the roof (roof ducts) or through the wall (wall ducts). Keep in
mind that the roof ducts must be sufficiently water-repellent and that the drop in pressure is kept
to a minimum (≤ 15 Pa at 250 m³/h).
• The unit may only be used with the appropriate RENSON®accessories and controls.
• Changes may not be made to the Endura Delta.
3.4 • Operating the system
• It is the installer’s responsibility to inform the user on how the unit works and how it can be
serviced for maintenance.
• Only use the unit for the purposes for which it has been designed, as stated in the manual.
• The maintenance instructions must be followed strictly in order to prevent damage and/or wear
and tear (See Section 12: “Cleaning and maintenance”).
• We recommend signing a maintenance contract.
3.5 • Safety instructions
• The unit must have contact hazard protection. This entails, among other things, that the
resident cannot come into contact with moving parts or live electrical connections under normal
circumstances without having consciously done something, such as:
− Removing the front panel with the appropriate tools;
− Disconnecting a duct while the unit is operating.
• The unit cannot be opened without using tools. Opening the unit can cause damage to the unit
or personal injury.
• The fingers could be injured in the opening at the top, where there is access to the fan.

Extra safety measures:
• Always ensure that the unit is turned off and unplugged before starting to work on it. Do this by
unplugging the power cable from the wall socket or by switching off the fuse (always check to
see if this has actually been done!).
• Always wait at least 30 seconds before turning the power back on.
• Use the appropriate/correct tools when working on the Endura Delta.
PLEASE NOTE:
The ventilation system must continuously operate, i.e. the Endura Delta may never be
turned off (legal requirement according to NBN D50-001, Chapter 4.2 System D).
3.6 • Frost protection
The Endura Delta is equipped as standard with a frost protection mechanism (see Section
10.2.5.1.3.a) to prevent frost from forming in the heat exchanger. When frost forms, there is a
decrease in your ventilation system’s yield and the heat exchanger could be damaged.
Every Endura Delta unit is equipped with basic frost protection. In addition, you can opt to
have the unit equipped with an electric preheater to guarantee that the unit continues to operate
correctly even in very harsh winter temperatures.
The preheater cannot be installed afterwards. So please make sure you are ordering the correct
type of unit, with or without a preheater, before confirming your order.
PLEASE NOTE:
It is important that the Endura Delta is always connected to the mains voltage so that
the frost protection is guaranteed.

4 • Description of the ventilation unit
4.1 • General description of the unit
The RENSON®Endura Delta is a balanced ventilation system within integrated heat exchanger.
Fresh air is blown into the home by 2 fans, which also extract the “polluted” air from the home.
The heat in the discharged air is partially transferred to the supplied fresh air via the counter-flow
plate. In order to guarantee an optimal yield, the system must operate in a balanced manner
(supply = discharge) as much as possible.
The correct operation of the Endura Delta is only guaranteed if there are sufficient and correctly
dimensioned air openings in the home’s interior doors. A door grille or a space under the door
can be added with a minimum feedthrough of 25 m³/h at 2 Pa.
• The Endura Delta is available in the following models:
− The unit is available in a left-facing (L) model (bypass and filters positioned to the left), but
can be converted to a right-facing (R) model.
− The unit is also available with 4 upper connections (T4) or with 2 upper and 2 lower
connections (T2/B2).
− The unit is available with or without an integrated preheater (extra frost protection) (PH).
