Ceiling concealed duct - Middle static pressure

Indoor unit

Compact

9. Installation

Indoor Units

9.5 Connection pipes to the indoor unit

1) Refrigerant piping work

please refer “REFRIGERANT PIPING WORK”.

2) Piping insulation

①

Perform heat insulation work completely on both gas and
the liquid pipe. Because improper insulation will result
due condensate formation over pipe.

②

Use the heat insulation material for the refrigerant piping
which has an excellent heat resistance (over 120°C).

③

Precautions in high humidity circumstance.

④

Refer to the insulation works.

3) Indoor unit drain piping

①

During drain piping connection, be careful not to exert
extra force on the drain port on the indoor unit.

②

The outside diameter of the drain connection on the
indoor unit is 32mm.

Piping material:

Polyvinyl chloride pipe inner diameter
Ø 25mm and pipe fitting

4) Caution for gradient of unit and drain

piping

- Without drain pump

①

Always lay the drain with downward inclination (1/50 to
1/100).
Prevent any upward flow or reverse flow in any part.

②

10mm or thicker formed thermal insulation shall always
be provided for the drain pipe.

※

U-trap is not required for low static model in which the
external static pressure is below 50 pa(5mm Aq)

Liquid pipe

Refrigerant pipe and thermal
insulation(Local supply)

Union for gas pipe

Insulation
(Local supply)

Clamp for insulation
(Local supply)

Make sure that there is no clearance here.

Overlap with
insulation

Thermal insulation for refrigerant pipe
(Local supply)

Thermal insulation for
piping(Local supply)

• Make sure to insulate any field piping all the way to the

piping connection inside the unit. Any exposed piping
may cause condensation or burns if touched.

CAUTION

1. Decline Installation of indoor unit is very important for

the drain of the duct type air conditioner.

2. Minimum thickness of the insulation for the connecting

pipe should be 5mm.

CAUTION

Attached drain hose

Bottom of unit

Downward 1/50~1/100 or more
