Ultro-flow continuous operation fan
Installation guide and technical data
Description
The Ultro-flow continuous operation fan provides continuous ventilation
to kitchens, bathrooms, utility rooms and cloakrooms. The unit has 3 speed
settings: trickle, comfort boost (automatically activated by the integral humidity sensor) and full boost
which is activated manually by switch or integral pull cord. The uniot has an adjustable boost run on timer
which is only triggered when boost has been activated for over 60 seconds to prevent unintentional boost
run on. The unit does not have a high dependency on background ventilators for operation and can work in
combination with Ultro-flow heat retention fans installed in bedrooms and living rooms.
General
Read this document before installing and using the Ultro-flow continuous operation fan. Keep the
document in a safe place for future reference. Ultro-flow fans are manufactured to comply with electrical
equipment regulations and must be installed by a technically qualified person. The manufacturer assumes
no responsibility for damage to persons or property resulting from failure to observe the regulations or
instructions contained in this document.

Installation, use and maintenance
The unit should not be used for applications other than those specified in this document.
Following removal of the product from the packaging the condition of the product should be checked and
any damage reported immediately. If in doubt consult a qualified technician.
Do not leave the packaging within the reach of small children or other vulnerable persons.
Do not touch the product with wet hands or feet.
Do not use the product in the presence of inflammable vapours, insecticides or petroleum products.
If any abnormalities in operation are detected, disconnect the unit from the mains supply and contact a
qualified technician immediately. Only use genuine parts for repairs.
The electrical system to which the unit is connected must comply with regulations.
Before connecting the unit to the power supply or the power outlet, ensure the data plate (voltage and
frequency) correspond to those of the electrical mains and the electrical power supply/socket is adequate
for maximum unit power. If not, contact a qualified technician.
The unit should not be used as an activator for water heaters, stoves etc., nor should it discharge into hot
air/fume vent ducts deriving from any type of combustion unit. It must expel air outside via the supplied
duct.
Operating temperature: 00C up to +500C.
The unit is designed to extract clean air only (air not containing grease, soot, chemical or corrosive agents,
or flammable or explosive mixtures).
Do not leave the unit exposed to atmospheric agents (rain, snow, sun etc.).
Do not immerse the unit 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
electrical regulations, to provide a full disconnection under the overvoltage category 111 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 risk or hazard.
Do not obstruct the fan or exhaust grill to ensure optimum air passage.
Ensure adequate air return/discharge into/from the room in compliance with regulations in order to ensure
proper unit operation.
If the environment into which the unit 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 the impeller is not accessible from the air outlet side as verified by contact with the
‘Test Finger’ (test probe ‘B’ of the norm EN61032) in compliance with the current safety regulations.
Ceiling installation
In order to guarantee the IPX4 degree of protection against moisture, the ceiling mounting kit (supplied
separately) MUST be used. Use only the rear entry hole for supply cables. If there is a possibility of
condensation along the air discharge duct, provide a drainage system to prevent condensation from
discharging into the environment through the fan.
Window installation
The window mounting kit (supplied separately) MUST be used.
Operation
The fan includes an adjustable humidity sensor and adjustable timer. The humidity threshold is adjustable
from 50% to 95% relative humidity via a dedicated trimmer. The timer is adjustable from 0 - 30 minutes via
a dedicated trimmer (figure 17B). The fan operates at the selected trickle speed (or off) and can be boosted
using the integrated pull cord switch or light switch. Once the boost switch is turned off the fan will
continue to run at the boost speed for the set period of time before reverting back to the trickle speed.
There is also a comfort boost triggered by a humidity level above the set threshold. The comfort boost flow
rate is approximately half way between the pre-set trickle and boost flow rate. Once the humidity level is
below the set point the fan will continue for a factory set period of time before returning to trickle speed.
The humidistat function can be deactivated by turning the HY trimmer completely anti-clockwise.

Pull cord operation –The pull cord works as the boost switch. Wire up as per figure 16G.
External switch operation –To boost the unit with an external switch such as a light switch the pull cord
should be disabled. To do this the pull cord should simply be cut when in the off position. The plastic caps
on the wiring terminals will need to be removed to allow the switch wires to be secured. Wire up as per
figure 16H.
External switch and pull cord operation –If the fan needs to be boosted via an external switch and pull
cord, the switch must be a double pole switch to prevent any interference between the fan and light. Wire
up as per figure 16H.
Installation type settings
Installation type can be selected using the JUMPERS among different options (figure 18).
Trickle speed settings
Trickle speed can be selected using the JUMPERS among different options (figure 18) Trickle speed can also
be set to off.
