INSTALLATION
ENGLISH
* Note 1) General location: When the pipe passes through indoors in which the indoor unit is
operated
- Apartment, classroom, office, mall, hospital, office-tel etc.
Note 2) Special location
1. When the location is air conditioned but has severe temperature/humidity difference
due to high ceiling
- Church, auditorium, theater, lobby etc.
2. When the location is air conditioned but the internal temperature/humidity of the
ceiling finishing is high
- Bathroom/swimming pool locker room etc. (Building with roof ceiling of sandwich
assembly type)
Note 3) General location: When the pipe passes indoors where the indoor unit is not operated
- Hall way etc. (Dormitory, school, office-tel)
Note 4) Negative condition: When below conditions 1 and 2 are met.
1. When the pipe passes indoors where the indoor unit is not operated
2. When the humidity is high, regionally, and there is no air flow in the pipe passing
area
- When installing the outside unit within the outside pipe tray or at a location where it
is ok to have freezes, apply 13 t.
- If you are not sure with the selection of heat insulation material, coordinate with the
supervision or HQ.
- The thickness of the above heat insulation material is based on the heat conductivity
of 0.088 W/m°C.
Condensate Drain
- The drainage performance has to be optimized by installing both primary and secondary drain
lines along with properly sized condensate traps in order to prevent property damage.
- Care should be taken to avoid the blocking of filter access panel while connecting condensate
drain lines. The primary and secondary condensate traps has to be primed after connecting to
the drain pan.
- A field supplied external condensate pan has to be installed underneath the entire unit if the
unit is above the living space . Other wise damage may result due to condensate over flow.
Also a additional external condensate line should run from unit in to the pan.
- The entire condensate should be drained from the external condensate pan to some noticeable
area. It is advised to install traps in condensate lines as near to the coil as possible. The outlet
of each trap should be below its connection to the condensate pan avert condensate from
overflowing drain pan.
- If located above the living area then all traps should be prime and insulated and also tested for
leakage.
- PVC 3/4 inch(19.05 mm) male pipe thread fitting is advised to use at condensate pan with
gentle tight.
- For easy drain flow the drain hose has to be pointed downward.
- Care should be taken to not use pipe joint connection or PVC/CPVC for units drain line
connection. Use only Teflon tape.
- For preventing winter freeze up on condensate line special means should be provided for
drainage.
