Application Information

Outdoor Clearance

If the condensing unit is operated in an atmosphere containing oils (including machine

oils), salt (coastal area), sulphide gas (near hot spring, oil refi nery plant), such as

substances may lead to failure of the unit.

• Where a wall or order obstacle is in the path of outdoor unit’s intake or exhaust airfl ow, follow the
installation guidelines below.

• For any of the below installation patterns, the wall height on the exhaust side should be 1200mm or less.

Application Information

Refrigerant Piping

Piping Length and Elevation

When the pipe length becomes too long, both the capacity and reliability drop. As the number of bends increases,
system piping resistance to the refrigerant fl ow increases, thus lowering the cooling capacity, and as the result
the compressor may become defective. Always choose the shortest path and follow the recommendation as
tabulated below:

Additional Charge

• The refrigerant gas is charged in the outdoor unit and, if the piping length is 7.5m, additional charge of the
refrigerant after vacuuming is not necessary.

• When the piping length is more than 7.5m, additional refrigerant charge (g) per additional 1m length as
tabulated:

Additional charge [g/m] 20

Example:

A5WMY10S & A5LCY10F with 15m piping length, additional piping length is 7.5m. Thus,
Additional charge = 7.5m x [20g/m]
= 150 [g]

Solution:

Based on the Performance Table,

1. Refer to the Indoor DB column,

- 25°C is located between 24°C & 27°C for 16°C WB.

- 25°C is located between 24°C & 27°C for 19°C WB.

- Thus, Interpolation needs to be applied.

2. Refer to the Indoor WB column,

- 17°C is located between 16°C & 19°C for 25°C DB.

- Thus, Interpolation needs to be applied.

3. Refer to the Outdoor DB column,

- 37°C is located between 35°C & 40°C.

- Thus, Interpolation needs to be applied.

Service & Maintenance

Service & Maintenance

• Disconnect from main supply before servicing the air conditioner.

• The unit is designed to give long life operation with minimum maintenance required. However, it should be regularly
checked and the following items should be given due attention.

Components Maintenance Procedures Period

Air Filter
(Indoor Unit)

1. Remove any dust adhering to the fi lter by using a vacuum cleaner
or wash in lukewarm water (below 40˚C) with a neutral cleaning
detergent.

2. Rinse the fi lter well and dry before placing it back onto the unit.

3. Note: Never use gasoline, volatile substances or chemicals to
clean the fi lter.

At least once every 2
weeks.
More frequently if
necessary.

Indoor Unit

1. Clean any dirt or dust on the grille or panel by wiping it with a
soft cloth soaked in lukewarm water (below 40˚C) and a neutral
detergent solution.

2. Note: Never use gasoline, volatile substances or chemicals to
clean the indoor unit.

At least once every 2
weeks.
More frequently if
necessary.

Condense Drain
Pan & Pipe

1. Check the cleanliness and clean it if necessary.

2. Check the condensate water fl ow.

Every 3 months.

Indoor Fan Check if there is any abnormal noise. If necessary.

Indoor / Outdoor
Coil

1. Check and remove the dirt between the fi ns.

2. Check and remove any obstacles which hinder air fl ow through
the indoor or outdoor.

Every month.

Power Supply

1. Check the running current and voltage for indoor and outdoor
unit.

2. Check the electrical wiring and tighten the wire onto the terminal
block if necessary.

Every 2 months.

Every year.

Compressor

No maintenance needed if refrigerant circuit remains sealed. How­ever, check for refrigerant leak at joint and fi tting.

Every 6 months.

Indoor Models

1. Open the front panel

• Hold the panel at the recesses on the main unit
(2 recesses on right and left sides) and lift it until
it stops.

2. Remove the front panel

• While lifting the front panel further, slide it to the
right and pull it to the front side. The left rotating
shaft is detached. Slide the right rotating shaft to
the left and pull it to the front side to remove it.

3. Attach the front panel

• Align the right and left rotating shafts of the front
panel with the grooves and push them all the
way in.

• Gently close the front panel. (Push both ends
and the center on the front panel.)

Rotating
shaft

Recess on
main unit

• Don’t touch the metal parts of the indoor unit. It may cause an injury.

• When removing or attaching the front panel, use a robust and stable stool and watch your steps carefully.

• When removing or attaching the front panel, support the panel securely with hand to prevent from it falling.

• For cleansing, do no use hot water above 40°C, benzene, gasoline, thinner, nor other volatile oils, polishing
compound, scrubbing brushes, nor other hand stuff .

• After cleaning, make sure that the front panel is securely fi xed.

28

Service & Maintenance

Pre Start Up Maintenance

(After Extended Shutdown)

 Inspect thoroughly and clean indoor and outdoor units.
 Clean or replace air fi lters.
 Clean condensates drain line.
 Clean clogged indoor and outdoor coils.
 Check fan imbalance before operation.
 Tighten all wiring connections and panels.
 Check for refrigerant leakage.

Outdoor Models

The design of the A5LCY-F/C outdoor series allows servicing to be carried out easily. The removal of the top,
front and side panels makes almost every part accessible.

Under normal circumstances, these outdoor units only require a check and cleaning of air intake coil surface
once every 3 months. However, if a unit is installed in areas subjected to much oil mist and dust, the coils must
be regularly cleaned by qualifi ed Air Conditioner Service Technicians to ensure suffi cient heat exchange and
proper operation. Otherwise, the systems life span may be shortened.

• Do not charge OXYGEN, ACETYLENE OR OTHER FLAMMABLE and poisonous gases into the unit when

performing a leakage test or an airtight test. These gases could cause severe explosion and damage if exposed to

high temperature and pressure.

• It is recommended that only nitrogen or refrigerant be charged when performing the leakage or airtight test.
