SELECTION PROCEDURE  
1. Model Selection (With actual examples)  
First step, to select the approximate model:  
Based on the cooling load and the cooling capacity listed in the capacity table, select the applicable model.  
Second step, to select the model:  
To select the model, the following conditions must be known:  
(1) Total cooling load or sensible cooling load  
(2) Indoor conditioned temperature (WB*1, DB)  
(3) Designed outdoor temperature (DB)*2  
(4) Designed air flow  
(5) Designed external static pressure (= Wind pressure loss of air duct)*3  
Notes:  
*1. The correct WB is required since it has a serious effect on the capacity.  
*2. The cooling capacity decreases as the outdoor temperature increases. Therefore, the estimated highest  
temperature during an air conditioning time frame is the "designed outdoor temperature". However, it is  
recommended that the abnormal outdoor temperature which may occur once or twice a year be excluded from  
the calculation to avoid selection of an excessively large capacity model.  
*3. The wind pressure loss of an air duct should be calculated correctly. If a value having an excessive allowance  
is used, an excessively large model will be selected. Moreover, an excessively high air flow will be induced  
during actual operation causing the generation of high operating sounds and carry-over of condensed water.  
(Step-1) Confirmation of operation range  
Confirm that the conditions given above for the model to be selected are within the  
operation range listed on Page 36.  
(Step-2) Calculation of actual air flow, external static pressure, and fan motor input  
Based on the designed air flow and external static pressure, obtain the actual air flow,  
actual external static pressure, and fan motor power input from the fan performance  
table for the model selected. For an explanation of how to use the fan performance  
table, see the following examples.  
Example: PE-8MYC, 50Hz  
Example 1. (To operate with values near to the designed air flow and external static pressure.)  
Condition : Designed air flow 70CMM  
Designed external static pressure 60Pa  
Calculation : The designed point is A. Therefore, duct resistance line passing A is

actual air flow obtained in Step-2, obtain the gross capacity from the gross capacity tables (pages  
16~35). Then, calculate the net capacity from the formula below by using the fan motor input obtained  
in Step-2.  
Net capacity (kW) = Gross capacity (kW) - Fan motor input (kW)

At 26ËšCDB, 19ËšCWB of Indoor,  
Q = 21.3, SHC = 16.3, T/I = 8.3  
Therefore, when air flow is 77(CMM)  
Q = 21.3 ✕ (1+(1.025 - 1.0) ✕ 7/10*) 21.7(kW)  
SHC = 16.3 ✕ (1+(1.044 - 1.0) ✕ 7/10*) 16.8(kW)  
T/I = 8.3 ✕ (1+(1.009-1.0))✕ 7/10*) 8.4(kW)  
Note * : 7/10 = (77-70)/(80-70)  
Therfore, the net capacity is,  
Net total cooling capacity = 21.7 (kw) - 0.6(kW)  
= 21.1 (kW)  
Net sensible cooling capacity = 16.8 (kW) - 0.6 (kW)  
= 16.2 (kW)

Lifting method.  
When the unit is to be lifted and moved, attach ropes to the suspension plates(3 p.c.s)  
provided on the top of the unit.  
When the unit is lifted, it 's center of gravity tends to shift the unit one side and so balance,  
such as that in the figure below, should be attained.  
The angles at which the ropes suspend the unit should be at least 60 at the compressor end  
and at least 45 at the condenser end. Care should be taken to avoid contact with the main unit  
while carrying.  
It is necessary to protect the unit with the blanket so that the ropes should not injure the unit.

Warning.  
Please follow the following procedures, during the piping connection work is carried out.  
If the procedures are not followed properly, the refrigerant and valve sheet might gush out from the ball valve.  
It might cause the injury.  
In case of Brazing type  
1. Open the ball valve cap before removing the by-pass tube.  
Then, turn the knob of the ball valve from ’close’ to ’open’  
position.  
2. Please repeat to close and open the ball valve of gas and liquid side at the same time (3 times or more).  
And finally make sure the ball valve is at close position.  
CLOSE  
OPEN  
3. Cut part A (two places) of the by-pass tube as shown in figure below.  
Caution

4. Make sure that the ball valve is wrapped with enough wet cloth, during the brazing of the by-pass tube  
(for cooling purpose). Make sure the temperature of ball valve is below 100 degree centigrade. (If the  
temperature of the ball valve is over 100 degree centigrade, the refrigerant and valve sheet might gush  
out from the ball valve. It might cause the injury.)  
enough wet  
cloth  
5. Please make sure the ball valve is cool enough when removing the by-pass tube. Wait for a while for  
further cooling of the ball valve, before the piping connection work begins.  
6. When the piping connection begins. Again, make sure that the ball valve is wrapped with enough wet  
cloth, during the brazing for cooling the ball valve. Make sure the temperature of ball valve is below 100  
degree centigrade. (If the temperature of the ball valve is over 100 degree centigrade, the refrigerant and  
valve sheet might gush out from the ball valve. It might cause the injury.)  
7. Before charging the refrigerant, vacuum the pipes to clear all the air and water.  
8. Charge the additional amount of refrigerant according to the table.  
9.Turn the knob of the ball valve to ’open’ position after leak check.  
10. Finally, put the cap back to the ball valve.

Refrigerant piping.  
4.  
Extension piping and installation parts are field supply.  
Perform the work only after carefully reading the  
appropriate instructions.  
A
Install the unit where the refrigerant piping is shortest,  
the difference between the indoor unit and outdoor unit  
is smallest.  
When the outdoor unit is lower.  
As pipes purchased in the market may contain  
dust, below them off with dry inlet gas.  
Take care not to allow dust and water content to enter  
the piping during pipe processing or installing.  
Minimize the number of bends, and make the bending  
radius as long as possible.  
B
Always observe the restriction(allowable length, height  
difference, pipe diameter) on the refrigerant piping.  
For soldering & brazing, use high-quality materials.  
When the outdoor unit is higher.  
Never purge air with a refrigerant. Always use a vacuum pump for purging.  
Provide proper insulation to the piping . Insufficient insulation cause poor cooling/heating  
performance or condensation drip, leading to unexpected trouble.  
Do not insulate gas or low pressure pipe and liquid or high pressure pipe together.  
For the connection of the refrigerant piping, leave the valve of the outdoor unit fully closed  
(as set before shipment), and no operate it until the connection between the indoor/outdoor  
units and refrigerant piping, refrigerant leak test and evacuation work have been completed.  
The maximum permissible values are shown below.  
Remove the cover (grommet) attached sheet metal at exit of heat exchanger pipe of indoor  
unit before connecting the local piping.  
(This cover is protect the pipe from sheet metal edge at unit transportation.)  
Please insulate liquid pipe & gas pipe (two places for each) with an insulated pipe of the  
attachment after connecting piping.
