(6) Ceiling Supension type (FDE)
(a) Selection of installation location
1) A place where good air circulation and delivery can be obtained.
Cold air throw
Models FDE36, 45, 56 type
Air throw
Conditions
(1) Installation height: 2.4 ~ 3.0 m above the floor
(2) Fan speed: Hi
(3) Location: Free space without obstacles
(4) Distance of reach indicates the horizontal distance after the wind touched down the floor.
(5) Air velocity at the throw: 0.5 ( m/sec.)
2) A place where ceiling has enough strength to support the unit.
3) A place where there is no obstruction to the return air inlet and supply air outlet ports.
4) Places exposed to oil splashes or steam (e.g. kitchens and machine plants).
Installation and use at such places will incur deteriorations in the performance or corrosion with the heat exchanger or damage
in molded synthetic resin parts.
5) A place where the space shown below may be secured.
6) This unit uses a mincrocomputer as a control device. Therefore avoid installing the unit near the equipment that generates
strong electromagnetic waves and noise.
(b) Installation preparation
1) Drilling of holes for interconnecting piping and wiring.
a) Drill a hole through the wall in accordance with the piping diameter. We recommend using a hole saw drill of 70 ~ 86 mm
diameter and the hole should be drilled on an incline from inside to outside.
b) Insert the accessory piping sleeve into the hold and cut it to the proper length in accordance with wall thickness.
2) Installation of suspension bolts
a) Use the template sheet to determine the positions of suspension bolts and refrigerant pipings. The refrigerant piping can be
routed either to the right, left, top or rear.
