CAUTION
• When the supply air is set twice as much as the exhaust air or
more by airow function, the Lossnay body indoor side must be
put additional insulation. Without additional insulation, it could
cause condensation and water drop from the unit.
• When on-site commissioning is planned, a straight duct
length more than 10xD (D=duct diameter) 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 measurement 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.
• 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.
• For LGH-160RVX3-E and LGH-200RVX3-E, thermistors are
built only in the lower unit. Lossnay unit controls its operation
according to the lower unit detecting temperature. Even when
actual return air temperature between the upper and the lower
unit is di󰀨erent, Lossnay operates according to the lower unit
temperature.
• Do not carry out the following types of duct construction.
(Doing so could cause a drop in the air volume and generate
abnormal noises.)

The duct should have a slope of 1/30 toward the outdoors, and the length of the duct at the slope should be longer than
required (see Standard installation examples section). Do not make a U-trap on the duct.
Otherwise, rainwater might be collected and it cause bad smells or broken of the unit by weight.
When installing vertically, do not install elbow duct facing the oor near the RA suction port of the unit. When installing a
downward bending duct or a damper on the RA, please install it at least 3 m away from the product so as not to generate
turbulence in the RA duct.
Otherwise, the unit may not work properly.
Do not connect the eld supply booster fan to the unit so that the air volume exceeds the maximum air volume of the unit
P-Q curve.
Otherwise, the unit may not work properly.
Make traps of su󰀩cient height to the power and communication cables so that water running along the wires does not
enter the circuit box.
If not, there is a risk of product broken, malfunctions, smoke or re.
When wiring communication cable, make sure to seal the gap created at rubber bush on the side plate of the control box
due to passing through the cable to prevent from insects or small animals comes into the box (The seal is local supply).
If not, it might cause the re.
Do not lean on or put your weight on the product.
There is a risk of product deformation or injury.
When inserting or removing Lossnay cores, securely hold the handle until the end and insert or remove them one by one.
Otherwise, some parts might be damaged.
The specications of the unit are value in case of horizontal installation.
Be sure to install the DX coil unit (GUG-SL-E series) horizontally even if Lossnay unit is vertically oriented. Dripping of
drain water and deformation of the product will occur.
