1. Be sure the ceiling height is no less than the Figures in above table B column (page 35).
2. Unit must not be installed close to boiler flues.
3. Do not install pipes as indicated below to avoid excessive pressure drop.
4. Exessive use of flex-duct and long flex-duct runs should be avoided.
5. Fire dampers must be fitted as per national and local fire regulations.
6. Unit must not be exposed to ambient temperature above 40° C and should not face an open fire.
7. Take action to avoid dew and frost.
As shown by drawing below, unit will produce dew or frost when saturation curve is formed from A to C. Use pre-heater to
ensure conditions are kept to right of the curve (B to B' , to move C to C) to prevent condensation or frost formation.
If this situation arises, pre-heat the fresh air to pass from B to B' , and bring C to C' . This will prevent the formation of conden-
sate and ice.
8. To avoid the outdoor exhaust air cycling back to indoor, the distance between the two vents installed on the
outside wall should be over 1000 mm.

Loose or incorrect wiring conection can cause explosion or fire when the unit starts to work. Use only rated power voltage.
Don't install, move or re-install the unit by yourself. Improper action may cause unit instability, electric shock or fire.
Running the unit continuosly in an abnormal status may cause failure, electric shock or fire.
Don't put fingers or objects into vents of fresh air or exhaust air supply. Injury may be caused by the rotation of the impel-ler.
Don't change, disassemble or repair the unit by yourself. Improper action may cause electric shock or fire.
Switch off the power and breaker when you clean the exchanger.
Isolate power during extended off periods. Isolate power and take care when cleaning unit (electrocution).
Clean the filter regularly. A blocked filter may result in poor indoor air quality.
