Overview

1. SYSTEM OVERVIEW
UTC KENINGAU
The air conditioning systems used in UTC Keningau are:
1) VRV air cooled system
2) Air cooled split unit system
One VRV systems are provided for each government department. Split unit
systems are used in the Lower ground floor and in special requirement areas within the
building. Daikin products are used for all the cooling equipment in the building. Refer to
the appendix for details of the nearest dealer and the contact details of Daikin Malaysia
Sdn Bhd in Sabah.
A. AIR CONDITIONING SYSTEM (VRV)
1.. The system comprises of the following equipment and materials: -
( i) 7 sets of VRV IV Daikin Outdoor Unit at Level 2
(ii) Wall Mounted and Cassette Type Indoor Units in Each department.
(iii) 7 nos of Control Panel in the A/C room at Level 2
(iv) 7 sets of Insulated Refrigerant Piping from indoor to outdoor units
(v) 7 sets of Signal Cable from indoor to outdoor units
2 VRV Overview
VRFs are typically installed with an Air conditioner inverter which adds a DC inverter to the compressor
to support variable motor speed and thus variable refrigerant flow rather than simply perform on/off
operation. By operating at varying speeds, VRF units work only at the needed rate allowing for substantial
energy savings at partial-load conditions. Energy savings of up to 55% are predicted over comparable
unitary equipment. This also results in greater control of the building's interior temperature by the
building's occupants.
VRFs in UTC Keningau come in two pipe system format, a liquid line and a gas line. The main pipes are
insulated with metal jackets and the branch pipes are insulation by conventional rubber nitrite insulation.
Refnet joints are used to branch out the refrigerant pipes from the main pipes to each indoor unit.
The picture in the next page shows the components of the VRV system

Safety Considerations
[Place of Installation]
•• Make sure that the air conditioner is located in a
sufficiently ventilated place not surrounded by
obstacles.
•• Do not use the air conditioner in the following places.
a. Places with a mist of mineral oil, such as cutting oil.
b. Locations such as coastal areas where there is a lot of
salt in the air.
c. Locations such as hot springs resorts where there is a
lot of sulfur in the air.
d. Locations such as factories where the power voltage
varies a lot.
e. In cars, boats, and other vehicles.
f. Locations such as kitchens where oil may splatter or
there is steam in the air.
g. Locations where equipment that produces
electromagnetic waves is found.
h. Places with an acid or alkaline mist.
i. Places where fallen leaves are accumulated or weeds
grow close together.
•• Take snow protection measures.
Contact your local dealer for the details of snow protection
measures, such as the use of a snow protection hood.
[Electrical Work]
•• Do not attempt to conduct electrical work or
grounding work unless you are licensed to do so.
Consult with your local dealer for electrical work and
grounding work.
•• Use a dedicated circuit for the air conditioner.
[Pay Attention to Operating Sound]
•• Be sure to use the following places.
a. Places that can sufficiently withstand the weight of the
air conditioner and suppress the operating sound and
vibration of the air conditioner.
b. Places where warm air from the air outlet of the outside
unit or the operating sound of the outside unit does not
annoy neighbors.
•• Make sure that there are no obstacles close to the
outside unit.
Obstacles close to the outside unit may drop the
performance of the outside unit or an increase in the
operating sound of the outside unit.
•• Consult your local dealer if the air conditioner in
operation generates unusual noise.
[Drainage through Drainpipe]
•• Make sure that the drainpipe is installed properly to
drain water.
If no water is discharged from the drainpipe while the air
conditioner is cooling operation, the drainpipe may be
clogged with dust or dirt and water leakage from the indoor
units may result.
Stop operating the air conditioner and consult your local
dealer.

Precautions for Group Control System or Two Remote Controller Control System
This system provides two other control systems beside individual control (one remote controller controls one indoor unit) system.
Confirm which type of your unit is the following system.
•• Group control system
One remote controller controls up to 16 indoor units. All indoor units are equally set.
•• Two remote controller control system
Two remote controllers control one indoor unit (in case of group control system, one group of indoor units). The unit is
individually operated.
Note
•• Contact your local dealer in case of changing the combination or setting of group control and two remote controller control systems.
01_EN_3P362438_2C.indd 7 2014/02/18 14:26:18

Optimum Operation
Observe the following precautions to ensure the system operates properly.
•• Prevent direct sunlight from entering a room during cooling operation by using curtains or blinds.
•• Do not leave doors and windows open. If the doors and windows remain open, air will flow out of your room causing a
decrease in the cooling or heating effect.
•• Do not use other heating devices directly beneath the indoor unit.
If you do, they might get deformed by the heat.
•• Never place objects near the air inlet or the air outlet of the unit. It may cause deterioration in the effect or stop the operation.
•• Adjust the room temperature properly for a comfortable environment. Avoid excessive heating or cooling.
•• Ventilate often.
Extended use requires special attention to ventilation.
•• Keep the indoor unit and remote controller at least 3.5 ft. away from televisions, radios, stereos, and other similar equipment.
Failing to do so may cause static or distorted pictures.
•• Turn off the main power supply switch to the unit when the unit is not used for longer periods of time. If the switch is on, it uses
electricity. Before restarting the unit, turn on the main power supply switch 6 hours before operation to ensure smooth running.
(Refer to the chapter “Maintenance” in the indoor unit manual.)
•• Fully use the function of air flow direction adjust.
Cold air gathers on the floor, and warm air gathers in the ceiling.
Set the air flow direction parallel during cooling or dry operation, and set it downwards during heating operation.
Do not let the air blow directly to a person.
•• It takes time for the room temperature to reach the set temperature.
We recommend starting the operation in advance using schedule operation.
Seasonal Maintenance
Caution
•• Do not touch the air inlets or aluminum fins of the outside or indoor units.
Touching them may result in injury.
•• Do not wash the outside or indoor units with water.
An electric shock or fire may result.
•• Watch your steps at the time of air filter cleaning etc.
If the scaffold is unstable, you may fall or topple down, thus causing injury.
•• Be sure to stop the operation, and turn the breaker off before cleaning.
This may cause electric shock and injury.
•• Consult with the dealer for cleaning the interior of the indoor units.
Incorrect cleaning may damage the plastic parts and cause failures, such as water leakage, and an electric shock may result.

01_EN_3P362438_2C.indd 8 2014/02/18 14:26:18

Following Symptoms are not Air Conditioner Troubles

The system does not operate
•• The air conditioner does not start immediately when restarting or changing the operation mode.
If the operation lamp lights, the system is in normal condition.
To prevent overloading of the compressor motor, the air conditioner starts 5 minutes after it is turned ON again in case it was turned OFF just
before.
CENTRAL
•• If “ CONTROL ” is displayed on the remote controller and pressing the operation button causes the display to blink for a few
seconds.
This indicates that the central device is controlling the unit.
The blinking display indicates that the remote control cannot be used.
•• The system does not start immediately after the power supply is turned on.
Wait 1 minute until the micro computer is prepared for operation.
stops sometimes
It
•• The remote controller display reads “U4” or “U5” and stops but then restarts after a few minutes.
This is because the remote control is intercepting noise from electrical appliances other than the air conditioner, and this prevents communication
between the units, causing them to stop.
Operation automatically restarts when the noise goes away.

Cool/heat cannot be changed over
MASTER
•• When the display shows “ CONTROLLED ”.
It shows that this is a slave remote controller.
Refer to “Setting the Cool/Heat Change over Master”.
MASTER
•• When the Cool/Heat selector switch is installed and the display shows “ CONTROLLED ”.
This is because COOL/HEAT changeover is controlled by the Cool/Heat selector. Ask your local dealer where the remote control switch is
installed.

Fan operation is possible, but cooling and heating do not work
•• Immediately after the power is turned on.
The micro computer is getting ready to operate. Wait 10 minutes.

The fan speed does not correspond to the setting
•• The fan speed does not change even if the fan speed control button is pressed.
During heating operation, when the room temperature reaches the set temperature, the outside unit goes off and the indoor unit changes to
whisper the fan speed.
This is to prevent cold air blowing directly on occupants of the room.
The fan speed will not change even if the button is pressed, when another indoor unit is in heating operation.

The fan direction does not correspond to the setting
•• The fan direction does not correspond to the remote control display.
The fan direction does not swing.
This is because the unit is being controlled by the micro computer.
01_EN_3P362438_2C.indd 9 2014/02/18 14:26:18

Following Symptoms are not Air Conditioner Troubles

White mist comes out of the unit
Indoor unit
•• When humidity is high during cooling operation.
If the interior of indoor unit is extremely contaminated, the temperature distribution inside a room becomes uneven. It is necessary to clean the
interior of the indoor unit. Ask your local dealer for details on cleaning the unit. This operation requires a qualified service person.
•• Immediately after the cooling operation stops and if the room temperature and humidity are low.
This is because warm refrigerant gas flows back into the indoor unit and generates steam.
Outside unit
•• When the system is changed over to heating operation after defrost operation.
Moisture generated by defrost becomes steam and is exhausted.

Noise of air conditioners
Indoor unit
•• A “zeen” sound is heard immediately after the power supply is turned on.
The electronic expansion valve inside an indoor unit starts working and makes the noise. Its volume will reduce in about 1 minute.
•• A continuous low hissing sound like flowing water is heard when the system is in cooling operation or at a stop.
When the drain pump (an optional accessory) is in operation, this noise is heard.
•• A squeaking sound is heard when the system stops after heating operation.
Expansion and contraction of plastic parts caused by temperature change make this noise.
•• A low sound like dripping water is heard while the indoor unit is stopped.
When the other indoor unit is in operation, this noise is heard. In order to prevent oil and refrigerant from remaining in the system, a small amount
of refrigerant is kept flowing.
Outside unit
•• When the tone of operating noise changes.
This noise is caused by the change of frequency.
Indoor unit, outside unit
•• A continuous low hissing sound is heard when the system is in cooling or defrost operation.
This is the sound of refrigerant gas flowing through both indoor and outside units.
•• A hissing sound which is heard at the start or immediately after stopping operation or defrost operation.
This is the noise of refrigerant caused by flow stop or flow change.

Dust comes out of the unit
•• When the unit is used after stopping for a long time.
This is because dust has gotten into the unit.

The units can give off odors
•• During operation.
The unit can absorb the smell of rooms, furniture, cigarettes, etc., and then emit it again.

The outside unit fan does not rotate
•• During operation.
The speed of the fan is controlled in order to optimize product operation.

The compressor or fan in the outside unit does not stop
•• This is to prevent oil and refrigerant from remaining in the compressor. The unit will stop after 5 to 10 minutes.

The inside of outside unit is warm even when the unit has stopped
•• This is because the crankcase heater is warming the compressor so that the compressor can start smoothly.

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 flow 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:

Example:
FTK10TV1 & RK10FV1 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.
3. Refer to the Outdoor DB column,
-- 37°C is located between 35°C & 40°C.
