CAUTION
• When on-site commissioning is planned, a straight duct
length more than 10xD (D=duct diameter or equivalent)
from the source of turbulence like bends, contractions and
dampers etc, to the measurement point is recommended for
correct measurement.
In the United Kingdam, on-site measurment should
therefore be measured in accordance with BSRIA guideline
(Commissioning Air System. Application procedures for
buildings AG3/89.3(2001))
•
Before attaching the ducts, check that no (debris or any other)
foreign matter (scraps of paper, vinyl, etc.) has found its way
inside the ducts.
• Do not touch the damper plate inside Lossnay unit when
connecting the ducts. (When the rectangular duct is secured
with screws, check that the screws are not collided to the
damper plate.)
• If it is expected that the ambient temperature around the place
where the Lossnay unit is installed will be high during the
summer air conditioning season, it is recommended that the
indoor duct work be covered with insulation material.
• Do not place the auxiliary blower to the exhaust side air
passage.
Do not carry out the following types of duct construction. (Doing so
could cause a drop in the air volume and generate abnormal noises.)
• Extremely
sharp bends
• Multiple bends • Bends right next
to the outlet
• Extreme reduction in
the diameter of the
connected ducts

CAUTION
• Select a duct heater in compliance with local and national
laws, ordinances, and standards.
Select a duct heater that has obtained the CE mark.
• Always select a heater that is equipped with a non-self-
resetting safety device.
Do not directly supply power from the Lossnay unit to the
duct heater.
(Doing so could cause re.)
• Install a circuit breaker for the duct heater in compliance with
all applicable laws, ordinances, and standards.
• Install the duct heater separated from the product by a
distance of 2 m or more.
(Failure to do so may result in equipment damage due to the
transmission of residual heat from the heater.)
• When using a heater without a temperature control function,
select a heater with a capacity that is matched to the air
volume.
• Do not use the heater outside the set air volume.
(If the heater’s capacity is too larger, this may result in the
heater frequently turning ON/OFF.)
(If the heater’s capacity is too small, this may result an
inability to heat.)
• Ensure that the duct heater and Lossnay are wired and that
the Lossnay function settings have been congured, and then
always check operation by trial operation.
• For the duct heater output, see function setting SW5-6.
