CAUTION
• Select a duct heater in compliance with local and national
laws, ordinances, and standards.
Select a duct heater that meets adequate standard in each
country.
• 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 fire.)
• 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 2.2 yd (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 configured, and then
always check operation by trial operation.
• For the duct heater output, see function setting SW5-6.

(when a sensor or other equipment is connected)
Using a field supply sensor, etc., make connection by inserting the
optional remote display adaptor (PAC-SA88HA-E or PAC-725AD) in
the connector CN17 (Red) as shown by the figure.
Lossnay will operate the fan speed following the table below,
regardless of the remote controller setting.

Use this in such a way that it ventilates at low fan speed normally,
and when the external sensor detects contamination of indoor air,
it changes to high fan speed operation.
