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.
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 18.
(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 and fan motor
power from the fan performance table for the model input selected. For an explanation of how to
use the fan performance table, see the following examples.
Example: PRHG-10, 50Hz
Example 1. (To operate with values near to the designed air flow and external static pressure.)
Condition : Designed air flow 100CMM
Designed external static pressure 60Pa
Calculation : The designed point is A. Therefore, duct
resistance line passing A is dotted line.
Therefore, actual point is B for
fan speed 1088rpm.
(Select a pulley near A point to fan speed.)
Actual air flow = 110CMM
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

At 26˚CDB, 19˚CWB of Indoor,
Q = 28.3, SHC = 22.6, W = 9.6
Therefore, when Air flow is 110 (CMM)
Q = 28.3 ✕ 1.012 28.6 (kW)
SHC = 22.6
W = 9.6 Note * : crrection factors of air flow
(Step-3) Calculation of net capacity
Example: PRHG-10, 50Hz cooling
Condition:
Indoor conditioned temp. : 26˚CDB, 19˚CWB
Designed outdoor temp. : 40˚CDB
Actual air flow : 110CMM
Indoor fan motor input : 1.9kW (See P.6, 17)
Outdoor fan motor input : 0.5kW (See P.6)
Calculation :
The sections of the gross capacity table applicable
for the above conditions are shown right.
Therfore, the net capacity is,
Net total cooling capacity = 28.6 (kw) - 1.9 (kW)
= 26.7 (kW)
Net sensible cooling capacity = 22.9 (kW) - 1.9 (kW)
= 21.0 (kW)
• Refrigerant cycle energy efficienty
(1) COP =
(2) EER =
• System energy efficienty
(1) COP =
(2) EER =
Notes:
1. COP : Coefficient of performance
2. EER : Energy efficiency ratio
3. Temperature condition of COP, EER (ARI Standard Ratings)
Indoor entering air temp. : 80˚FDB (=27˚CDB), 66˚FWB(=19˚CWB)
Outdoor entering air temp. : 95˚FDB (=35˚CDB)
4. Total input = Compressor input + Indoor fan motor input (page 17) + Outdoor fan motor input (page 6).

2. Efficiency Calculation
Based on the indoor conditioned temperature (WB,DB), designed outdoor temperature (DB), and the
actual air flow obtained in Step-2, obtain the gross capacity from the gross capacity tables (pages
9~16). 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)

All series of air conditioners are designed for outdoor installations and are to be placed on a slab or rooftop, however if the
air conditioner is to be installed in a plant room application, please contact your equipment supplier prior to installation.
Access for both service and installation must be provided to the compressors, control wiring and fans as shown below.
(1) Care must be taken to prevent recirculation air.
To stabilize compressor, condensing pressures it is
recommended that wherever possible the condenser air
inlet side be faced away from prevailing winds.
(2) For rooftop installation, the type of mounting base
depends on the roof construction.
A built-up roof may not support the weight of the unit and
so it may be necessary to support the unit by adding
structural members below it.
(3) The units are equipped with hoisting plates for rigging
and hoisting of the unit.
The hoisting plates are located on the top of the unit.
When hoisting the unit with a crane, spreader bars must
be used to prevent damage to side panels by the
supporting cables.
(1) The figure shows the use of the roof curb available for
mounting these units.
(2) The curb should be sealed and fixed to the roof by
weather stripping. A suggested means of sealing the unit
and roof curb is shown below.

The rain water come down from joint part.
So prevent rain water from entering the building.
(1) Series PRHG side flow units are equipped with horizontal supply and
return air openings. Duct connection to the unit should be made with duct
flanges and secured directly to the air openings with flexible duct
connectors to avoid normal noise transmission.
(2) For vertical air supply, a field supply plenum should be used.
The figure below shows the recommended method for duct connection.
(3) Series PRHG down flow units are equipped with vertical supply and return
air openings. Duct connection to the unit should be made with duct
flanges to avoid normal noise transmission.
(4) To prevent air leakage, all duct seams should be taped.
Ducts run in air spaces that are not air-conditioned must be insulated and
provided with a vapor barrier.
Ducts exposed to the outside must be weather proofed.
For quiet operation, we recommend that the insulation on the supply duct
be placed inside, lining the duct.
(5) Where ducts from the outside enter a building, the duct openings in the
building should be sealed with weather stripping to prevent rain, duct,
sand, etc. from entering the building.
(6) Fans will not accept any external resistance to airflow and what provision
is available if ductwork is to be fitted to the external fans.
(7) Correctly sized filters must be fitted and there is no provision within the
unit, however the filters may be installed in the return air.
(8) Duct earth wiring must be connected, refer to term 4 (outline drawing)
about earth point.
In case of down flow, we must use accessory screw attached on control
box cover.
When the unit is to be lifted and moved, attach ropes to the suspension
plates (4 pcs) provided on the top of the unit.
When the unit is lifted, it is 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.
An additional charge is unnecessary.
The table below shows the amount of the charge when the factory is shipped.
(1) The condensate drain fitting (R 1) is provided. The drain pipe can be led
out at the right side.
(2) The drain pipe must be provided with a trap on the outside of the unit and
also installed at an incline for proper drainage, as shown below.
(3) To prevent condensate formation and leakage, provide the drain pipe with
insulation to safeguard against sweating.
(4) Upon completion of the piping work, check that there is no leakage and
that the water drains off properly.

5. Before starting the trial run
Please execute the following confirmations to prevent wrong connection.
If there is wrong connection, it may damage fan controller, but also damage the unit.
Confirmation
Please intercept the power supply without fail, and secure safety when you execute detaching wiring, the connector,
and the measurement machine to the following work.
Step
Step 1
Confirmation matter Check Correspondence
Connected confirmation
Step 1-1 Is fan controller's power supply input wiring position connected correctly as
shown in installed manual?
Step 1-2 Is the phase of the connection of fan controller power supply input (TB IN)
accurate?
Step 1-3 Is the phase of the connection of fan controller output (TB OUT) accurate?
Step 1-4 Is the phase of connection of fan controller output wiring to fan motor accurate?
Step 2
Drive confirmation
Step 2-1 Does the fan rotate in a correct direction, when the unit is driven ?
Step 2-2 The thermistor for the condensing temperature detection is removed to CN01.
Drive to the cooling operation.
(The unit stops abnormally when the cooling operation drive is continued for a
long time occasionally. - High pressure switch off)
Whether LED01 has blinked is confirmed.
When the unit is in operation, the fan controller output voltage measured
in TB OUT, and checked whether the output of about 200V.
There is a problem when it is an output of about 300V.
Step 2-3 The thermistor for the condensing temperature detection is surely connected
with CN01 as before.
Step 2-4
Step 1-5 Is the thermistor for the condensing temperature detection of the attachment
connected with CN01?
Step 1-6 Is the thermistor for the condensing temperature detection accurately installed
in the unit?
Step 1-7 In case of the heat pump model, the wiring for full load input is connected with
CN04?
In case of the heat pump model and the heating drive is possible, the heating
drive is executed and the voltage of CN04 is input AC198V - 264V.
In that case, the fan must be full load drive.
(The output of the power-supply voltage is confirmed in TB OUT. )
When heating cannot be driven, step 1-7, step 1-8 is executed again.
In case of the heat pump model, the wiring for full load input is connected
accurately in control box?
