>> Installation Precautions for Ceiling Type

1. When installing the product, check the level of the floor and then install it horizontally.
2. When installing the product, be sure to provide a minimum slope (1/80–1/100) for the drain pipe.
3. When installing the product, ensure that there is space to remove the filter and space for maintenance purposes.
(Foldable and soft frame filters are optional depending on the site conditions.)
4. To facilitate easy maintenance of the product, be sure to install an inspection port (400 X 400 – 600 X 600) in the direction where the piping is installed.
5. When installing the product, consider ensuring that the air intake area is equal to or larger than the discharge area.
6. Ensure proper connection by designating the lower header of the heat exchanger as (SUPPLY) and the upper header as (RETURN).
7. Piping Precautions
A. Perform on-site insulation and taping on each connection part of the pipe to prevent water leakage and condensation in the pipe area.
B. Install manual valves to allow for locking when the system will not be in operation for an extended period.
C. Ensure that the drain hose is installed without any twists or bends.
D. After completing the piping work, remove any foreign substances from the pipes and perform a pressure test.
8. Separate ducts and diffusers can be connected.
(However, performance may decrease depending on the external static pressure. Select either high-pressure or ceiling concealed type according to site conditions.)
9. The standard rotary provided is delivered separately and must be installed on site.
10. Fan coil units can be connected in multiple/parallel with one standard rotary switch.
(However, when it is the same product, when the wind speed is fixed to either strong, medium, or weak, and when the total operating current of the connected
products is less than 3 A)
