3.Piping length and the elevation

Install the branch pipe so that pipe length and difference between high and low will not exceed below SPEC.

	L2	Branch	Spec.
	L3	Pipe Length(m)
		Total(Main+Branch)	110
		Main Pipe(L1)	50

		Indoor-Indoor_(b)	10
	Main (L1)

•When installing the branch pipe, direction and angle of installation is not limited.

•Take care so that burrs and foreign material may not enter into the cutting surface when connecting.

•Connect a gas pipe of Ø19.05 by using the socket in the indoor unit and connect remaining those by cutting or direct insertion to the diameter of pipe.

•Don’t use the liquid pipe by too bending or twisting.

4. Refrigerant Additional Charging Method

There is not additional charging of refrigerant by main pipe of 30m below.

For additional charging method, see below table.

Single	Refrigerant=(L1-30)*0.05
Double	Refrigerant=(L1-30)*0.05+(L2+L3-20)*0.03
Triple	Refrigerant=(L1-30)*0.05+(L2+L3+L4-20)*0.03
D/Twin	Refrigerant=(L1-30)*0.05+(L2+L3+L4+L5-20)*0.03

<Ref. Addition charging method>

(L1=Main Pipe, L2~L5 : Branch Pipe

CAUTION:

•Rated performance for refrigerant line length of:7.5m

•Capacity is based on standard length and maximum allowance length is on the basis of reliability.

•Improper refrigerant charge may result in abnormal cycle.

•Oil trap should be installed every 10 meters.

	• During the installation, care should be
	taken not to damage electric wires.

NOTICE

•Thoroughly study the following installation locations:

1.In such places as restaurants and kitchens, considerable amount of oil steam and flour adhere to the turbo fan, the fin of the heat exchanger and the drain pump, resulting in heat exchange reduction, spraying, dispersing of water drops, drain pump malfunction, etc.

In these cases, take the following actions:

•Make sure that the ventilation fan for smoke-collecting hood on a cooking table has sufficient capacity so that it draws oily steam which should not flow into the suction of the air conditioner.

•Make enough distance from a cooking room to install the air conditioner in such a place where it may not suck in oily steam.

Air conditioner

Take enough distance

Use the ventilation fan for smoke-collecting hood with sufficient capacity.

Cooking table

2.Avoid installing air conditioner in such circumstances where cutting oil mist or iron powder is in suspension in factories, etc.

3.Avoid places where inflammable gas is generated, flows in, is stored or vented.

4.Avoid places where sulfurous acid gas or corrosive gas is generated.

5.Avoid places near high frequency generators.
