TIPS FOR SAVING ENERGY |
|
|
|
Here are some tips that will help you minimize the power consumption |
|
when you use the air conditioner. You can use your air conditioner |
|
more efficiently by referring to the instructions below: |
|
|
•Do not cool excessively indoors. This may be harmful for your health and may consume more electricity.
•Block sunlight with blinds or curtains while you are operating the air conditioner.
•Keep doors or windows closed tightly while you are operating the air conditioner.
•Adjust the direction of the air flow vertically or horizontally to circulate indoor air.
•Speed up the fan to cool or warm indoor air quickly, in a short period of time.

Preheat the compress for more than 6 hours.
Run each indoor unit in turn to make sure the pipe work has been fitted correctly
Explain the use of the system as clearly as possible to your customer an make sure all relevant documentation is in order
!CAUTION
•The above list indicates the order in which the individual work operations are normally carried out but this order may be varied where local conditions warrants such change.
•The thickness of the piping should comply with the relevant local and national regulations for the designed pressure 3.8MPa(551.1psi).
•Since R410A is a mixed refrigerant, the required additional refrigerant must be charged in its liquid state.(If the refrigerant is charged in its gaseous state, its composition changes and the system will not work properly.)
OUTDOOR UNITS INFORMATION
!CAUTION
•Ratio of the connectable Indoor Units to the Outdoor: 50 ~ 160%
•Ratio of running Indoor Units to the Outdoor: 10 ~ 100%
•A combination operation over 100% cause to reduce each indoor unit capacity.
ALTERNATIVE REFRIGERANT R410A
The refrigerant R410A has the property of higher operating pressure in comparison with R22. Therefore, all materials have the characteristics of higher resisting pressure than R22 ones and this characteristic should be also considered during the installation. R410A is an azeotrope of R32 and R125 mixed at 50:50, so the ozone depletion potential (ODP) of R410A is 0.
!CAUTION
•The wall thickness of the piping should comply with the relevant local and national regulations for the designed pressure 3.8MPa(551.1psi).
•Since R410A is a mixed refrigerant, the required additional refrigerant must be charged in its liquid state.
If the refrigerant is charged in its gaseous state, its composition changes and the system will not work properly.
•Do not place the refrigerant container under the direct rays of the sun to prevent it from exploding.
•For high-pressure refrigerant, any unapproved pipe must not be used.
•Do not heat pipes more than necessary to prevent them from softening.
•Be careful not to install wrongly to minimize economic loss because it is expensive in comparison with R22.
SELECT THE BEST LOCATION
Select space for installing outdoor unit, which will meet the following conditions:
•No direct thermal radiation from other heat sources
•No possibility of annoying neighbors by noise from unit
•No exposition to strong wind
•With strength which bears weight of unit
•Note that drain flows out of unit when heating
•With space for air passage and service work shown next
•Because of the possibility of fire, do not install unit to the space where generation, inflow, stagnation, and leakage of combustible gas is expected.
•Avoid unit installation in a place where acidic solution and spray (sulfur) are often used.
•Do not use unit under any special environment where oil, steam and sulfuric gas exist.
•It is recommended to fence round the outdoor unit in order to prevent any person or animal from accessing the outdoor unit.
•If installation site is area of heavy snowfall, then the following directions should be observed.
-Make the foundation as high as possible.

Seasonal wind and cautions in winter
•Install correctly with the prospect of snow or cold temperatures in mind.
•Install the outdoor unit ideally not to come into contact with snow directly. If snow piles up it will freeze to the heat exchanger, and the system will malfunction. Attach a snow hood to prevent any issues.
•The raised support platform must be high enough to allow the unit to remain above possible snow drifts, and must be higher than the maximum anticipated snowfall for the location.
•Remove any snow that piles higher than 100mm on the top of the unit.
-In areas of high wind, do not install the units heat exchanger or discharge fan perpendicular to the wind direction.

Foundation for Installation
•Fix the unit tightly with bolts as shown below so that unit will not fall down due to earthquake or gust.
•Use the H-beam support as a base support
•Noise and vibration may occur from the floor or wall since vibration is transferred through the installation part depending on installation status. Thus, use anti-vibration materials (cushion pad) fully (The base pad shall be more than 200 mm(7-7/8 inch)).
At least 200mm (7-7/8 inch)
The corner part must be fixed firmly. Otherwise, the support for the installation may be bent.
Get and use M10 Anchor bolt.
Put Cushion Pad between the outdoor unit and ground support for the vibration protection in wide area.

Preparation of Piping |
|
Main cause of gas leakage is defect in flaring work. Carry out correct |
|
flaring work in the following procedure. |
|
-Use the accessory piping kit or the pipes purchased locally.
-Measure the distance between the indoor and the outdoor unit.
-Cut the pipes a little longer than measured distance.
-Cut the cable 1500mm(59-1/16inch) longer than the pipe length.

!CAUTION
•Always use a charge hose for service port connection.
•After tightening the cap, check that no refrigerant leaks are present.
•When loosening a flare nut, always use two wrenches in combination, When connecting the piping,
always use a spanner and torque wrench
in combination to tighten the flare nut.
Union
• When connecting a flare nut, coat the flare(inner and outer faces) with oil for R410A(PVE) and hand tighten the nut
3 to 4 turns as the initial tightening.
Plumbing materials and storage methods
Pipe must be able to obtain the specified thickness and should be used with low impurities.
Also when handling storage, pipe must be careful to prevent a fracture, deformity and wound.
Should not be mixed with contaminations such as dust, moisture.
Opening shutoff valve
1Remove the cap and turn the valve counter clockwise with the hexagon wrench.
2Turn it until the shaft stops.
Do not apply excessive force to the shutoff valve. Doing so may break the valve body, as the valve is not a backseat type. Always use the special tool.
3 Make sure to tighten the cap securely.
Closing shutoff valve
1 Remove the cap and turn the valve clockwise with the hexagon wrench. 2 Securely tighten the valve until the shaft contacts the main body seal.
3Make sure to tighten the cap securely.
* For the tightening torque, refer to the table on the below.

Insulation of shutoff valve
1Use the heat insulation material for the refrigerant piping which has an excellent heat-resistance (over 120°C).
2Precautions in high humidity circumstance:
This air conditioner has been tested according to the "ISO Conditions with Mist" and confirmed that there is not any default. However, if it is operated for a long time in high humid atmosphere (dew point temperature: more than 23°C), water drops are liable to fall. In this case, add heat insulation material according to the following procedure:
-Heat insulation material to be prepared... EPDM (Ethylene Propylene Diene Methylene)-over 120°C the heat-resistance temperature.
-Add the insulation over 10mm thickness at high humidity environment.

Nitrogen substitution method
Welding, as when heating without nitrogen substitution a large amount of the oxide film is formed on the internal piping.
The oxide film is a caused by clogging EEV, Capillary, oil hole of accumulator and suction hole of oil pump in compressor.
It prevents normal operation of the compressor.
In order to avoid this problem, Welding should be done after replacing air by nitrogen gas.
When welding plumbing pipe, the work is required.
Welding Point
Oxide scale
Note) should not block the outlet side. When the internal pressure in pipe is abo ve the atmospheric pressure, pinhole is o ccurred and it is a leakage cause.
