1. Safety precautions

1.3.  Before electric work

 Caution:

•  Be sure to install circuit breakers. If not installed, electric shock may result.
•  For the power lines, use standard cables of sufficient capacity. Otherwise, a 

short circuit, overheating, or fire may result.

•  When installing the power lines, do not apply tension to the cables. If the 

connections are loosened, the cables can snap or break and overheating or 
fire may result.

1.4.  Before starting the test run

 Caution:

•  Turn on the main power switch more than 12 hours before starting operation. 

Starting operation just after turning on the power switch can severely damage 
the internal parts. Keep the main power switch turned on during the operation 
season.

•  Before starting operation, check that all panels, guards and other protective parts 

are correctly installed. Rotating, hot, or high voltage parts can cause injuries.

•  Be sure to ground the unit. Do not connect the ground wire to gas or water 

pipes, lighting rods, or telephone grounding lines. If the unit is not properly 
grounded, electric shock may result.

•  Use circuit breakers (ground fault interrupter, isolating switch (+B fuse), and 

molded case circuit breaker) with the specified capacity. If the circuit breaker 
capacity is larger than the specified capacity, breakdown or fire may result.

•  Do not touch any switch with wet hands. Electric shock may result.
•  Do not touch the refrigerant pipes with bare hands during operation. The 

refrigerant pipes are hot or cold depending on the condition of the flowing 
refrigerant. If you touch the pipes, burns or frostbite may result.

•  After stopping operation, be sure to wait at least five minutes before turning off 

the main power switch. Otherwise, water leakage or breakdown may result.

1.5.  Using R410A refrigerant air conditioners

 Caution:

•  Use C1220 copper phosphorus, for copper and copper alloy seamless pipes, 

to connect the refrigerant pipes. Make sure the insides of the pipes are clean 
and do not contain any harmful contaminants such as sulfuric compounds, 
oxidants, debris, or dust. Use pipes with the specified thickness. (Refer to page 
5) Note the following if reusing existing pipes that carried R22 refrigerant.

-  Replace the existing flare nuts and flare the flared sections again.
-  Do not use thin pipes. (Refer to page 5)

•  Store the pipes to be used during installation indoors and keep both ends of 

the pipes sealed until just before brazing. (Leave elbow joints, etc. in their 
packaging.) If dust, debris, or moisture enters the refrigerant lines, oil dete-
rioration or compressor breakdown may result.

•  Use ester oil, ether oil, alkylbenzene oil (small amount) as the refrigeration 

oil applied to the flared sections. If mineral oil is mixed in the refrigeration 
oil, oil deterioration may result.

•  Do not use refrigerant other than R410A refrigerant. If another refrigerant is 

used, the chlorine will cause the oil to deteriorate.

•  Use the following tools specifically designed for use with R410A refrigerant. 

The following tools are necessary to use R410A refrigerant. Contact your 
nearest dealer for any questions.

Tools (for R410A)

Gauge manifold

Flare tool

Charge hose

Size adjustment gauge

Gas leak detector

Vacuum pump adapter

Torque wrench

Electronic refrigerant charging scale

•  Be sure to use the correct tools. If dust, debris, or moisture enters the refriger-

ant lines, refrigeration oil deterioration may result.

•  Do not use a charging cylinder. If a charging cylinder is used, the composition 

of the refrigerant will change and the efficiency will be lowered.

2. Installation location

2.1. Refrigerant pipe

Refer to Fig. 4-1.

2.2.  Choosing the outdoor unit installation location

•  Avoid locations exposed to sources of heat.
•  Select a location from which noise emitted by the unit will not inconvenience neighbors.
•  Select a location permitting easy wiring and pipe access to the power source and 

indoor unit.

•  Avoid locations where combustible gases may leak, be produced, flow, or accumulate.
•  Note that water may drain from the unit during operation.
•  Select a level location that can bear the weight and vibration of the unit.

•  Avoid locations where the unit can be covered by snow. In areas where heavy snow fall 

is anticipated, special precautions such as raising the installation location or installing a 
hood on the air intake must be taken to prevent the snow from blocking the air intake or 
blowing directly against it. This can reduce the airflow and a malfunction may result.

•  Avoid locations exposed to oil, steam, or sulfuric gas.
•  Use the transportation handles of the outdoor unit to transport the unit. If the unit 

is carried from the bottom, hands or fingers may be pinched.

2.3.  Outline dimensions (Outdoor unit) (Fig. 2-1)

Constraints on indoor unit installation

You should note that indoor units that can be connected to this outdoor unit are the 
following models. 
•  Indoor units with model numbers P06-P54 (PUMY-P36 : P06-P36) can be con-

nected. Refer to the table below for possible 1-8 (PUMY-P36 : 1-6) room, indoor 
unit combinations.

Verification

The rated capacity should be determined by observing the table below. The unit’s 
quantities are limited in 1 to 8 units. For the next step, make sure that the total rated 
capacity selected will stay in a range of 50% - 130% of the outdoor unit capacity.

•  PUMY-P36 

18,000 - 46,800 Btu/h 

•  PUMY-P48 

24,000 - 62,400 Btu/h

Combinations in which the total capacity of indoor units exceeds the capacity of the 
outdoor unit will reduce the cooling capacity of each indoor unit below their rated 
cooling capacity. Thus, combine indoor units with an outdoor unit within the outdoor 
unit’s capacity, if possible.

1.6.  Precautions for salt damage–resistant model  

(“-BS” model)

Although this product (only “-BS” model) has been designed to be resistant to salt 
damage, observe the following precautions to maintain the performance of the unit.
1. Avoid installing the unit in a location where it will be exposed directly to seawater 

or sea breeze.

2. If the cover panel may become covered with salt, be sure to install the unit in a 

location where the salt will be washed away by rainwater. (If a sunshade is installed, 
it may be difficult for rainwater to clean the panel.)

Fig. 2-1

3. To ensure that water does not collect in the base of the outdoor unit, make sure 

that the base is level, not at angle. Water collecting in the base of the outdoor unit 
could cause rust.

4. If the unit is installed in a coastal area, clean the unit with water regularly to remove 

any salt build-up.

5. If the unit is damaged during installation or maintenance, be sure to repair it.
6. Be sure to check the condition of the unit regularly.
7. Be sure to install the unit in a location with good drainage.
