16 Vertical Air Handling Unit
Installation
• 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 leak-
age.
• PVC 3/4 inch(19.05mm) 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.
* 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 fin-
ishing 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 13t.
- If you are not sure with the selection of heat insulation material, coordinate with the super-
vision or HQ.
- The thickness of the above heat insulation material is based on the heat conductivity of
0.088W/m°C.

After the confirmation of the above conditions, prepare the wiring as follows:
1) Never fail to have individual power specialized for the air conditioner. As for the method
of wiring, follow by the circuit diagram posted on the inside of control box cover.
2) Provide a circuit breaker switch between power source and the unit.
3) The screws which fasten the wiring in the casing of electrical fittings are liable to come
loose from vibrations to which the unit is subjected during the course of transportation.
Check them and make sure that they are all tightly fastened. (If they are loose, it could
give rise to burn-out of the wires.)
4) Specification of power source
5) Confirm that electrical capacity is sufficient.
6) Be sure that the starting voltage is within 10% plus or minus of nameplate voltage rating.
7) Confirm that the cable thickness is as specified in the power sources specification.
(Particularly note the relation between cable length and thickness.)
8) Never fail to equip GFCI breaker when installing the air handler near wet or moist loca-
tions.
9) The following troubles would be caused by voltage drop-down.
• Vibration of a magnetic switch, damage on the contact point, fuse breaking, disturbance by the
normal function of an overload protection device.
• Proper starting power is not given to the compressor.
