Before the electrical work has not been completed, connect a convex joint in the drain pipe connection to provide a
water inlet . Then, check if water leaks from the piping system and that drain flows through the drain pipe normally .
Air Duct
lnstallation work for air outlet ducts
Calculate the draft and external static pressure and select the length, shape and blowout .
A Blowout duct
2-spot, 3-spot and 4-spot with Ø 200 type duct are the standard specifications
Note:
(1) Shield the central blowout hole for 2-spot .
(2) Shield the blowout hole around the center for 3-spot .
Limit the difference in length between spots at less than 2:1 .
Reduce the length of duct as much as possible .
Reduce the number of bends as much as possible . (Corner R should be as larger as possible .)
Use a band . etc . to connect the main unit and the blowout duct flange .
Conduct the duct installation work before finishing the ceiling .
Connection of suction, exhaust ducts
a. Fresh air inlet
lnlet can be selected from the side or rear faces depending on the working conditions .
Use the rear fresh air inlet when the simultaneous intake and exhaust is conducted . (Side inlet cannot be used .)
b. Exhaust (Make sure to use also the suction.)
