PRECAUTIONS FOR INSTALLATION, USE AND MAINTENANCE
Fig. 1
Introduction
The Elta SANO PIV WALL is a positive input ventilation unit suitable for installation on a wall for
dwellings without a loft space. It continuously supplies fresh air through a discharge diffuser, that
should be situated in the central hallway or landing. The unit has multiple options for the inlet spigot;
on both sides and the back of the unit allowing multiple installation options. The unit can also be
configured to discharge air from the left or right hand side.
The power consumption shown is Normal mode.

• Do not immerse the device or its parts in water or other liquids.
• Turn off the main switch whenever a malfunction is detected or in case of cleaning/maintenance.
• For installation an omnipolar switch should be incorporated in the xed 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).
• Do not obstruct the fan or exhaust grille to ensure optimum air passage.
• Ensure adequate air supply into 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.
• Install the product so that the impeller is not accessible from the air outlet side as veried by contact with the Test Finger (test probe “B” of the
norm EN61032) in compliance with the current safety regulations.
Unit Setting
The SANO PIV WALL unit runs continuously a low ventilation level supplying fresh clean air into your home. This fresh air dilutes the stale and humid
air in your home and is a great way to prevent and even cure condensation dampness and mould problems.
The unit setting is selected by the installer to suit the size, layout, thermal properties and moisture production in the home. Getting this setting right
is very important and is often based on the experience of the installer. It is as important not to over ventilate as it is to under ventilate a home. Elta
Fans Residential team has much experience in setting PIV units and can be contacted anytime for advice.
The unit has numerous automatic speed adjustments to optimise ventilation and energy use.
Normal Mode
The unit will run in this mode for the vast majority of its time supplying until the unit’s integral temperature sensor switches it to “Standby” mode,
or the “Override Boost” mode (if connected via a suitable switch) is activated by the occupants.
This rate is set via 3 RATE dip switches shown in the wiring diagram, when leaving the factory this is set to 21l/s.
Energy Saving Mode
When the temperature of air being brought into the home is above an adjustable temperature the unit will automatically switch to a lower speed.
This lower speed will reduce the energy used by the ventilation unit and the amount of uncomfortably warm air being brought in. This temperature
can be selected for conditions where condensation is less likely to occur such as the summer months.
This trigger temperature is adjustable between 15-25°C, via V1 trimmer (shown in the wiring diagram). The default when leaving the factory is
19°C. It is usually adjusted to 1°C above the temperature the home is heated to
The fan speed is adjustable between via the HY trimmerand can be set to between -50% and 50% of the trickle speed.
FOR EXAMPLE: The trickle is set at 21l/s, HY trimmer set to -20%: when triggered the boost will be 21+(-4.2)=16.8l/s.
It is recommended that the Heat Recovery Mode (boost above 0%) is not used for the WALL mounted PIV and the boost increase is set at or below
0% (default).
Summer Standby Mode
The summer shutdown function limits the chance of the house overheating when temperatures outside reach a level that is uncomfortable. The unit
will essentially switch off when the temperature reaches a “Standby” trigger temperature to save energy and prevent undesirable warm air being
introduced unnecessarily in to the home.
Some customers wish to have their unit operating all year round e.g. for Radon Gas control or pollen ltration during summer. That’s why an
adjustable trigger temperature has been incorporated.
This temperature set point is adjustable via V2 trimmer (shown in the wiring diagram) between 20° and 40°C, the default when leaving the factory
is 26°C.
Override Boost Mode
The unit’s automatic controls can be overridden to operate the unit at its maximum airow by means of a user switch.
The override boost can be triggered via a dedicated external volt free switch connecting GND and S3 terminals (shown in diagram). Purge operation
overrides any other speed settings.
This function can be incorporated at installation stage or later. The unit will function automatically with or without it.
To prevent excessively warm air being supplied to the home and to protect the components of the unit, the purge will not operate above 40°C.
OPERATION

MAINTENANCE
Make sure the mains supply of the unit is disconnected before performing any maintenance. The maintenance must be carried out by a qualied
technician and in accordance with local rules and regulations.
Filters of the unit require changing according to the lter change period. When the lters are dirty less air will be supplied by the unit and impact the
effectiveness of the unit. In areas of high pollution e.g. beside main roads more regular replacement may be required. Filters can be supplied by Elta Fans.
Filters should be checked annually or if a drop in ventilation rates are noticed.
The lter should be checked regularly to determine if it needs cleaning or replacement. External environmental conditions will determine how often
the lter will need to be cleaned or replaced. Reduced airow, perhaps accompanied by an increase in noise level, may provide indication that the
lter needs to be cleaned or replaced. The lter should be inspected and cleaned or replaced as required at intervals not exceeding 2 years
and always replaced at intervals not exceeding 5 years.

DIMENSIONS (mm)
Duct work should be kept as simple as possible minimising duct length and the number of bends. This will optimise the Units effectiveness.
Ducting from the external to the unit should be kept as short as possible as condensation can form on the cold ductwork if it is not insulated.
The unit comes tted with round 100mm spigots for easy tment of round rigid ducting. If rectangular 110x54 ducting is required a rectangular to
round adaptor can be tted directly to the spigot. To do this the spigot must be cut to 25mm length.
Enough room needs to be allowed to access the side screws for maintenance. Allen Keys are supplied with every unit to minimise the space
requirement.
The blades of internal grilles tted in the central hallway should be pointing upwards to better spread the fresh air.
The unit should be connected to a smoke alarm to stop the unit in the event of a re to stop the spread of smoke and prevent evacuation. Guidance
should be sort from Approved Document B (Fire Safety).
When the ducting is passed through re boundaries adequate re protection should be incorporated. Guidance should be sort from Approved
Document B (Fire Safety).

WALL MOUNTING
Before mounting ensure the desired location leaves enough room for access and maintenance. There are multiple mounting congurations make
sure you have decided on the most suitable before drilling any holes.
The back panel can be removed and offered up to the wall ensuring that is level. The mounting hole positions can now be marked and rear duct
entry if required.
Drill the marked holes and insert the supplied wall plugs.
Double check the holes line up with the rear panel and reassemble the unit in the desired conguration.
Lift the unit up and align the mounting holes with the wall plugs.
The supplied screws can then be screwed in securing the unit to the wall.
