Please refer to the manuals for the other systems. For connection of a Lossnay remote controller (PZ-62DR-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 manual for the Lossnay remote controller (PZ-62DR-E). <Not connected to an external device> Example of System Lossnay Remote Controller (Optional parts) (PZ-62DR-E) Operation Run using the remote controller.

Energy recovery ventilation makes the fresh air temperature close to the indoor temperature in the winter and the summer season.

The following shows the effect "By-pass" ventilation will have under various conditions. 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. CAUTION l 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. l When set to auto ventilation mode while using the pre-heater function, the outdoor temperature may be detected as higher and the mode may change to by-pass mode, even in winter. Maintenance 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. (or when are indicated on the remote controller) 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.) 3) Air filters After pulling out the Lossnay cores, undo filter guides, then remove the air filters, located at the bottom left and right of the Lossnay cores, as below. Filter stopper Removing the parts 1) Maintenance cover 1. Remove the black screw. 2. Slide the fix piece to out side. 3. Open hinge wire. Maintenance cover Fix piece Filter guide Models LGH-F300 to F600RVX2-E: 2 cores, 4 filters Models LGH-F940 and F1200RVX2-E: 4 cores, 8 filters CAUTION l Bow filter stoppers a little to remove them from filter guide. l Take filter stoppers careful not to break them. Black screw Hinge wire Models LGH-F940 and LGH-F1200RVX2-E have 2 fix pieces. 2) Lossnay cores Take hold of the handle and draw the Lossnay cores out from the main unit. 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 104°F(40°C)) Vacuum cleaner Air filter Handle Lossnay core Handle Main unit Main unit Lossnay core Air filter Air filter Models LGH-F300 to F600RVX2-E Models LGH-F940 and F1200RVX2-E CAUTION l Never wash the filters in very hot water and never wash them by rubbing them. l Do not dry the filters by exposing them to a flame. Eng-3 Maintenance (continued) 2) Lossnay cores Use a vacuum cleaner to suck up the dust and dirt on the exposed surfaces of the Lossnay cores. Use a soft brush only to clean exposed surface areas. Do NOT wash in water. Vacuum cleaner (with brush attachment) Lossnay core CAUTION l Do not use the hard nozzle of the vacuum cleaner. It may damage the exposed surfaces of the Lossnay cores. l Under no circumstances should the Lossnay cores be washed in water. Assembly after maintenance Bearing in mind the following points, assemble the parts following the sequence for their removal in reverse. l Arrange the Lossnay core with the air filter side downward. l The filter has front and back side. Set the "FRONT" (printed) side of the filter on the outer side. Note l If are indicated on the remote controller, turn off the indication, after maintenance.

If the measuring point is close to sources of turbulence like bends, contractions and dampers etc, it is difficult to measure air volume correctly. A straight duct length more than 10D (D=duct diameter) from the source of turbulence is recommended for correct measurement. On-site measurement should therefore be measured in accordance with BSRIA guideline (Commissioning Air System. Application procedures for buildings AG3/89.3(2001)) After-sales servicing Consult with your dealer about the after-sales services provided for this Lossnay product. If you hear strange sounds, if no air is blown out or if some other trouble occurs, switch off the power and contact your dealer. Consult with your dealer concerning the cost of inspection or repair work. Recommended inspection and maintenance After several years of use, the following might occur. We recommend inspection and maintenance by a professional. - Entry of dust due to deterioration of filters - Abnormal noise or vibration due to the motor reaching the end of its service life - Air leakage due to the Lossnay core reaching the end of its service life The following are consumables: Motor / Supply air filter / Exhaust air filter / Lossnay core / Circuit board / Thermistor Repair costs include technical fee, cost of parts, (and business trip charges), etc. Attentive inspection Inspect your unit of good service! Fan do not run when the unit is turned on. Abnormal noises or vibrations while the unit is running. Have you Retarded or irregular rotations. noticed? (Motors are component which requires maintenance.) Burnt odor. Corroded or damaged installation section. Turn off the unit.
