ELTA FANS Mori HR Installation Manual

Introduction

MORI HR is a continuously running, alternate flow supply and extract fan with heat retention for use in
habitable rooms such as; living rooms, bedrooms, dining rooms basements and hallways. It is designed to
ensure adequate ventilation in enclosed environments. It is recommended that two units are installed in a
pair: when one unit is pulling, the other is pushing.
A pair of units can be installed in the same room or in different rooms (i.e. living room and bedroom).
The unit is suitable for installation on an outside wall.

Read this manual carefully before using the product and keep it in a safe place for reference.
This product was constructed up to standard and in compliance with regulations relating to electrical equipment and must be installed by technically
qualified personnel.
The manufacturer assumes no responsibility for damage to persons or property resulting from failure to observe the regulations contained in this
booklet.

PRECAUTIONS FOR INSTALLATION, USE AND MAINTENANCE

G

To achieve the best possible ventilation the unit should operate continuously, and only stopped for maintenance or service.

When heat exchange is not useful (for example in mid-seasons when indoor and outdoor temperatures are similar) it is

recommended to set the unit in “extract-only” or “intake-only” mode and not switch the fan off.

Every 70 seconds the unit alternates between being a supply fan and an extract fan. During the extract mode the units high efficiency heat
exchanger collects and retains heat from the extracted air, it then transfers the majority of this heat to the incoming air during supply mode,
recovering most of thermal energy which would be otherwise lost in the ventilation process.
The unit can be run continuously at a set speed by adding an internal link, or controlled via the dedicated controller, 149-SEN-CTRLS which
allows speed selection and triggering of free cooling mode.

S3 switch activates the “Free cooling “ (Bypass) mode , which stops alternate flow and keeps the fan in “extract-only” or “intake-only” mode, to
avoid the heat exchange when necessary. To set the extract-only” mode or “intake-only”, place the integral jumpers as per Fig.20A or Fig.20B).
The front cover LED indicates when the Free cooling mode is on.
An automatic “Boost”mode can be achieved through a dedicated switch.
Wiring configurations:

1. Constant run with alternate flow and heat retention on Speed 1 only – See diagram 18A.

2. Constant run with alternate flow and heat retention on Speed 2 only – See diagram 18B.

3. Constant run with alternate flow and heat retention on Speed 3 only – See diagram 18C.

4. Constant run with alternate flow and heat retention on Speed 1 with boost to Speed 3 triggered by external switching device (ordered
separately if required) – See diagram 18D.

5. Constant run with alternate flow and heat retention on Speed 2 with boost to Speed 3 triggered by external switching device (ordered
separately if required) – See diagram 18E.

6. Operation using controller 149-SEN-CTRLS (ordered separately if required) – See diagram 18F.
(a) Off.
(b) Constant run with alternate flow and heat retention on Speed 1.
(c) Constant run with alternate flow and heat retention on Speed 2.
(c) Constant run with alternate flow and heat retention on Speed 3.
(d) Constant run on selected speed in extract or supply mode only (supply or extract selectable at installation stage).
Please note that this switch can control one or two units to work in harmony i.e. when one unit is extracting the other is supplying which can
improve further the ventilation in a room or home. Wiring diagram for 2 units, diagram 18G.

OPERATION

any type of combustion unit. It must expel air outside via its own special duct.

• Operating temperature: -20°C up to +50 °C.

• The device is designed to extract clean air only, i.e. without grease, soot, chemical or corrosive agents, or flammable or explosive mixtures.

• Do not leave the device exposed to atmospheric agents (rain, sun, snow, etc.).

• Do not immerse the device or its parts in water or other liquids.

• Turn off the main switch whenever a malfunction is detected or when cleaning.

• For installation an omnipolar switch should be incorporated in the fixed wiring, in accordance with the wiring regulations, to provide a full
disconnection under overvoltage category III conditions (contact opening distance equal to or greater than 3mm).

• If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard.

• Do not obstruct the fan or exhaust grille to ensure optimum air passage.

• Ensure adequate air return/discharge into/from the room in compliance with existing regulations in order to ensure proper device operation.

• If the environment in which the product is installed also houses a fuel-operating device (water heater, methane stove etc., that is not a “sealed
chamber” type), it is essential to ensure adequate air intake, to ensure good combustion and proper equipment operation.

STANDARD

External grille in high quality, impact and UV-resistant ABS colour RAL 9010.

WARNING:

Ensure that the electric wiring to L and N is done correctly; an incorrect connection will lead to malfunction or permanent

damage of the fan.

Two or more units can operate at a fixed speed in a synchronised way (one unit extracts, the other supplies, and viceversa). Wiring diagrams: Fig
18 A-B-C.
The initial starting air direction is achieved by setting the dedicated jumper (Fig. 20A-20B)

RESET OF THE SYNCHRONISATION

Maintenance can be carried out by the user as indicated at page 14
Service must be perfmormed only by technically qualified personnel in accordance with local rules and regulations. Make sure that the mains
supply to the unit is disconnected (page 15).
Cleaning of the heat exchanger can be performed from outside as well.

MAINTENANCE AND SERVICE

Integral jumper set in position A (Fig.20A) means “extract” mode.
Intergal jumper set in position B (Fig.20B) means “intake” mode.
The jumper position defines both the air-flow direction when the unit is activated for the first time (for the synchronisation) and the air-flow
direction of the free-cooling mode.

JUMPER POSITION

If two or more units are controlled by means of the same controller (149-SEN-CTRLS or similar), they always operate in a synchronised way.

switched first OFF and then ON to reactivate (fig.31)
OPTION 2
If two or more units are not connected under the same main switch, to reset the synchronisation, press at the same time the black pin of each
unit (fig.33) at least 3 seconds.
