WARNING
Do not turn the remote controller on or off when flammable
gas has leaked. (It could catch fire or cause explosion with
sparks released from electric contactor.)
Open windows to ventilate.
Prohibited
Do not
disassemble
Do not touch
Wet hands prohibited
Use the specified power supply and voltage.
(Use of incorrect power supply could cause fire or electric
shock.)
Do not modify or disassemble.
(It could cause fire, electric shock or injury.)
Do not apply water to the unit and remote controller.
(Electrical shock can result.)
Do not wet
Don’t operate with wet hands.
(Electrical shock can result.)
Do not poke your fingers or sticks into the air intake and
outlet while the product is operating.
(Failure to heed this warning may result in injury.)
Make sure the power supply isolator is turned off on the
power distribution panel before starting maintenance.
(It could cause electric shock or injury if it is turned on.)
The instructions
given must be
followed.
When any abnormal conditions (burning smell, or others) are
observed, stop operation, turn off the power supply isolator
on the power distribution panel and consult your dealer.
(Continuing operation under such conditions could cause
electric shock, fire, or damage.)
CAUTION
Do not place a burning appliance in a place where it is
exposed directly to the wind from Lossnay. (It could
cause an accident as a result of incomplete combustion.)
Don’t operate with the “BY-PASS” when heating the
room in winter. (Condensed water may drip from the unit
and wet the surface of ceiling.)
Prohibited
Do not use at a place where exposed to high
temperatures (40˚C or higher), naked flames, or in
environment with heavy fumes. (It could cause fire.)
Do not use in an environment such as a chemical factory,
where hazardous gases such as acidic gases, alkaline gases,
organic solvent fumes, paint fumes, or gases containing
corrosive components are generated. (It could malfunction.)
The instructions
given must be
followed.
Securely install parts after maintenance.
(It could cause injury if parts fall.)
Put on gloves during maintenance. (It could cause injury.)
Make sure the power supply isolator is turned off on the
power distribution panel when Lossnay is not used for a
long period of time. (It could cause electric shock, power
leakage, or fire as a result of deteriorated insulation.)
The appliance is not to be used by children or persons
with reduced physical, sensory or mental capabilities, or
lack of experience and knowledge, unless they have
been given supervision or instruction.
Children should be supervised to ensure that they do
not play with the appliance.

Operation
Lossnay can be connected with Lossnay remoote controllers (PZ-60DR-E,PZ-41SLB-E,PZ-52SF-E),
and other Systems (City multi,Mr.slim,Central controller(MELANS))
Following shows the use of PZ-60DR-E,Please refer to the manuals for the other systems.
For connection of a Lossnay remote controller (PZ-60DR-E)
If the Lossnay’s operation is linked with the operation of an external device such as an air conditioner, the method of use will differ, so carry out
the appropriate operation in accordance with the following table. Also, please see the installation and user’s manual for the Lossnay remote
controller (PZ-60DR-E).
<If not connected to an external device> (PZ-41SLB-E can not be used together with PZ-60DR-E)

setting
Both fresh air supply and return air pass through the energy recovery
cores. Resulting in total heat exchange. Energy recovery ventilation
makes the fresh air temperature close to the indoor temperature in
the winter and the summer season.

1. Reduces cooling load
If the air outside is cooler than the air inside the building during the
cooling season (such as early morning or at night), “By-pass”
ventilation will draw in the cooler outside air and reduce the cooling
load on the system.
2. Night purge
“By-pass” ventilation can be used to release hot air from inside the
building that has accumulated in buildings a business district during
the hot summer season.
3. Office equipment room cooling
During cold season, fresh air can be drawn in and used as is to cool
rooms where the temperature has risen due to the use of office
equipment.
In the case of “By-pass” ventilation, the supply air temperature
slightly rises more than the outside air temperature because
of the heat effect around the ducts or the unit motors.
Maintenance
(or when “FILTER” and “CLEANING” are indicated on the remote
controller)
English
Remove all dust and dirt on air filters and Lossnay cores at regular
intervals in order to prevent a deterioration in the Lossnay functions.
Guideline: Clean the air filters once a year.
Cleaning the parts
1) Air filters
Use a vacuum cleaner to remove light dust. To remove stubborn dirt
wash in a mild solution of detergent and lukewarm water. (under 40°C)
Clean the Lossnay cores once two year.
(Clean the Lossnay cores once a year If possible.)
(Frequency should be increased depending on the extent of dirt.)

The above values apply during Lossnay ventilation when the fan speed is set to high speed.
The values given in the table for the noise level reflect the levels measured at a position 1.5 meters immediately below the unit in an anechoic
chamber.
*
Noise change or increase may occur because of the Bypass-Automatic function or Automatic fan speed change by timer setting.
*
Temperature Exchange efficiency (%) are based on winter condition.
