2. EQUIPMENT DESCRIPTIONS AND OPERATION PRINCIPLES
2.1. Data Panel and Microprocessor
URTP devices involve one panel. The panel has a power supplier by its structure in its body and a
microprocessor to manage the control equipments belonging to the device. No extra power or control panel
is required for URTP devices.
The security equipments belonging to the system has automatic and glass insurances, motor protection
switches, phase protection relay and thermo magnetic switch within the panel. The outer door of panel is
locked and involves another cover plate in itself. No personnel without technical competence should
intervene with this part.
There is a microprocessor processing signals coming from air quality, pressure, temperature and humidity
sensors within the panel. This microprocessor performs heating, cooling, air quality, fan control, damper
control procedures. Besides, accessories out of standards could also be checked. Additional modules could
be added to the microprocessor unit as to quantity of the options.
12
Moreover, Modbus providing communication with building automation system is procured as standard.
Along with that, additional modules could be added by the use of other various building automation systems
(Bacnet MS-TP, Bacnet IP, and Lonworks).
2.2. Compressors
In URTP devices, hermetic scroll-type compressors were used.
There are lubricant pans, pan heaters and vibration absorber wedges as standard at compressors for all
models.
2.3. Lubricants
So that compressors could operate without any problems, lubricants defined at compressors’ marks should
be used. Compressors with other brands could be used according to models for these units.
They have lubricant indicators at which the amount of lubricant could be seen. Pay attention to that the
amount of lubricant should absolutely be at the middle level of the indicator.
While low amount causes that compressor works dry and gets heated up, high amount causes operational
problems by leaking into the system. Moreover, lubricant in the compressor may leak to the system when
the device leans sideward during transports, don’t let the device to lean sideward more than 15 degrees
throughout this procedure.
The device won’t need any addition or reduction of lubricant except for the case of being damage.
2.4. Condenser Coil
In URTP devices, temperature changing gas heat exchangers are used for copper tubes, aluminum fins.
These heat exchangers function only as condenser in models working as coolers, while they function as
condenser in summer, evaporator in winter in models with heat-pumps. In case requested, normal aluminum
fins or epoxy-coated aluminum finned coil could be used.
2.5. External Axial Fans
The only purpose of these fans outside of the unit is to enable air flow over condenser coils of the device and
gas temperature within the heat exchanger to change. These fans are exposed to severe air conditions
because they work at outer environments. Fans should be controlled regularly and they should be made sure
to be uncovered by no object. Objects to affect air flow negatively causes that the fan doesn’t function and
accordingly causes to disturb operation of the system.
2.6. Indoor Fans
These fans are found within the device and their purpose is to direct conditioned air needed by user to the
ambient. This is done only by using the inner air or by partially taking from the outer air. The system was
designed to produce pressure and air flow, and for this inner unit fan cycles should be adjusted according to
system requirements. For this, fans could be set into variable cycles by frequency inverter control. The
device could be adjusted to the system in an easy, fast and economic way (optional feature).
13
2.7. Thermostatic Expansion Valve
Thermostatic expansion valves are cooling system elements and have functions for the system to work
correctly. They are connected to the evaporator inlet on liquid line. They enable that right amount of
refrigerant is sent to the evaporator and lowers pressure, evaporation pressure and temperature of refrigerant.
Thermostatic expansion valves enable to have a stable superheating degree at the evaporator. Superheated
refrigerant steam not includes any liquid refrigerant, so liquid leakage risk to the compressor is eliminated.
If superheating degree at the evaporator is high then valve becomes active and opens again.
2.8. Sensors
There are up to 14 sensors according to options and accessories to be used in the system. These are found at
different sections as air and gas sides. They enable that read values are turned into 0-10 voltages by being
sent to the microprocessor and necessary data for the processor are generated.
There are high pressures prostates at both circuit 1 and circuit 2 at gas side of the system. There are also
sensors reading temperature and pressure of gas at absorption side. These are having a vital importance in
continuously monitoring the refrigerant and in that the system operates by a correct regime.
Room temperature sensor is found at the top of room control panel of the device and senses that room
conditions are suitable or not, enables that the device operates within proper capacity by giving right
commands.
Blow temperature sensor which is the sensor that found at air side of the device control temperature degree
of conditioned air.
External air temperature sensor helps control the capacity of device by continuously calculating atmosphere
temperature.
External air humidity sensor measures humidity degree of atmosphere continuously and provides a sensitive
control for free cooling/ heating operation mode.
Room air humidity sensor is found at return air section of the device and increases control sensitiveness for
free cooling/ heating operation mode.
With carbon dioxide sensor that is linked to return air duct, ambient air quality is put under control
constantly. For the desired degree, this sensor enables that the system set to the correct operation point and
to be informed for hazardous conditions.
Smoke detector measures variable air degrees and enables that the system alarms before or right at the
moment of fire.
Freeze thermostat is connected to the device in case there is additional, hot water coil in the device and gives
alarm to the system in case water temperature is decreased under 5 degrees.
High temperature thermostat is used in case an additional electric heater is used in the system and also in
order to deactivate heater in case heating surface temperature exceeds the defined temperature.
Differential pressure sensor is connected to the fan unit and pressure produced by the device and
accordingly flow rate are measured to control the flow.
Differential pressure switch is used for the filter in the system. When the defined values are exceeded,
beside giving alarm for the filter, provides variance for fan cycle continuously as to the constantly changing
filter pressure loss (optional feature).
2.9. Filters
In URTP devices, there are G4 filters as standard. This filter found at the inlet of inner unit of the device is
used with the purpose of protecting the inner equipment. Regular controls and cleanings are of great
importance so that the system operates effectively.
14
2.10. Refrigerant (R410A)
In this URTP device, R410A gas is used as cooling gas. These devices are designed according to
characteristics of this gas and shouldn’t be operated with another kind of gas in no way. Global heating
potential of R410A gas is GWP: 1975. This gas involves fluorinated greenhouse gasses within the
framework of Kyoto Protocol.
2.11. Free Cooling and Heating
In URTP models of ECO series, there are damper and control systems enabling free heating and cooling.
This system is activated in mid-seasons and when desired temperature values could be reached temperature
values of outer ambient air. The system does the necessary conditioning by only sending the outer ambient
air to the area and doesn’t activate heating or cooling systems within its body while doing it or activates
them under partial loads. This enables to reduce user costs and also to protect the environment by protecting
natural resources.
3. INSTALLATION
3.1. Transport and Conservation
Roof connector should be carried separately from the
device and conserved.
Lift the roof connector from transport points.
The isolation material within roof connection elements at
conservation area should be protected from External air
conditions and possible rodents.
Don’t drag your device to place it on assembly spot while
carrying it. Make use of transport and lifting opening at its
bottom part. The device should be no means be transported
by holding it on pipe connections, door handles or duct
connection points.
During transport, transport planks (timber bars) should be
put between ropes so that the ropes don’t damage
your device. Otherwise, ropes may damage metal
sheet details or condenser lamellas of your device.
For URTP 55/70/90/110/140, 4 transport points, for
180 and 230 models, 6 transport points should be
utilized. They are shown at figures.
The distance between timber bars and
transport point should be adjusted in balance. When
the device is seen to have no balance in test lift,
connection point should be re-determined to enable
the balance.
The distance between rope connections and
transport point should be adjusted to nearly 5 meters
(base angles between timber bar and lifting point
knot should be lower than 60C). Having this distance
lower may cause the rope to break off.
Don’t put high weights on the device to cause
permanent damage.

The device shouldn’t be inclined so to lean sideward more
than 15 degrees. This situation damages the device
compressor.
When your device is deactivated, make sure that the
dampers aren’t turned off.
The device should be kept where the relative humidity rate
doesn’t exceed 80% and ambient temperature should be
kept between -25 and 55o C.
Dust, gas, steam and chemical materials such as abrasives
shouldn’t be contacted with the device and device elements.
Roof-type air conditioners might generally get damaged
generally during transport, loading and lowering and especially in case a crane is used. Pallet truck or
forklift should be used while lifting and transporting small devices by considering device weights
determined at tables given on delivery note or size information section.
In transports with forklift, the device should be placed evenly on knives. In case it is placed under knives,
the bottom of device will get damaged.
After placing the device on roof connector, lifting legs (a quantity of four) could be taken off.
Lifting and lowering of big devices should be carried on with a crane by using suitable equipments.
Silk rope suitable to device size and weight should be used for device security and so that the device
doesn’t get damaged while lifting and lowering with the crane, additional profiles should be used to
prevent ropes from tightening on the device body and the device should be transported by considering its
weight and having taken the necessary security precautions to prevent turning over and slipping.
During lifting and transporting the device, no one should stand under the device and at movement area,
crush hazard should be paid attention to.
Before packaging, markings and warning tags showing notification values of the device should have been
placed properly. While lifting the device, the weight defined in KG at the tag should be paid attention to.
Devices should be wrapped with nylon and they should be packaged on lift feet against risks of getting
scratched, getting deflected and deformed while loading, transporting and shipping them. Palletized
boxes used against probable quakes and future damages on them while shipping devices are bigger than
the devices in size. Parts of the devices with low body endurance are supported with styropor
(polystyrene) of 1 cm and rapped with nylon.
If it needs storing for a while before install the device on its place, this storage should be a dry
environment not to get affected by External air conditions.
General device sizes according to models are defined below. (For more detailed size data, you may look
at the “Size Data” section.)

3.2. Device placement and Considerations
The device shouldn’t be unpackaged until it reaches to the installation spot so that no damage emerges.
It is also crucial that where the device will be placed be chosen carefully. Ground should have the nature
to bear weight of the device and dynamic loads to arise during operation of the device.
Necessary lightening should have been provided at the environment where the device is placed so that
maintenance works could be carried out with ease.
There should be left extra spaces at the width to let for maintenance works at the area where the device will
be placed. Spaces to be needed for placement according to device models are seen below.
If there are higher walls than the device’s height near
where the device will be placed and if condenser side of
the device faces this wall, the line between upper surface
of the device and upper surface of walls should be 60
degrees at maximum. At higher degrees, the device won’t
have the necessary air flow.
If the device cannot be taken away from walls, the linage
to the device’s condenser should be hollowed out and air
flow should be provided.
If the distance between wall and the device more than
17
scale of 2 x C, the wall doesn’t obstruct air flow.
If two devices are to work adjacent to each other and condenser and condenser surfaces are to face each
other, the distance in-between should be higher than 2 x C +300 mm.
If the device is to work on a mezzanine floor, condenser air duct slice should be at least 1.5 fold of fan inlet
diameter.
If the device is to work on a porch or
near somewhere like a porch, a distance
of at least 1.2 fold of the porch
protrusion should be lest between the
device and wall.
IF H > 1 M,
THEN B > A.
The height ‘H’ not being less than 3 meters for
semi-closed environments is very important for the
device to work effectively.
IF H < 1 M,
THEN C > A.
If the device is to work on snowy weather, a snow-shield should be put on the condenser side of the device.
The snow-shield’s surface area should be at least 1.2 fold of the condenser’s surface areas.
WARNİNG: Condenser surface of the device should absolutely be protected from snow. Snow shouldn’t be
let to cover condenser’s surface.
3.3. Installation of Unit Body and Components
18
Details about placement of the device are given at the figures below.
Necessary spaces are left on roof concrete for roof connection of the device place of which is determined. After roof
connection elements are placed o at the space left, the device is placed securely with fill material.
Outer surface of roof connector and ground should be covered with water-tight isolation material. And upper surface
of the isolation material should be put under protection.
Before the device is placed, roof connector could be placed. In such cases, falls or injuries could be prevented by
covering open spaces of roof connector with safety equipments.
The device should be put on roof connection by the help of a
crane. Isolated bottom part of the device should be placed in a
way to contact with the roof connection.
3.4. Montage of Air Ducts
Connection type of roof connection of ducts and connection type
of roof connection to the device for connection types with air
ducts are as below.
19
For air duct-connection systems from the bottom;
For air duct-connection systems from sides;
Some points should be paid attention to in movements of air ducts right after the device. If connection is to be
provided via an elbow joint (and this isn’t a preferred method), this elbow joint should absolutely have a wide curve
and shouldn’t narrow right after the section. The elbow joint should curve after at least 2 meters. This condition
applies for devices both with bottom and side connections.
Duct connections should be provided suitable to roof connector connection sections. It is crucial that the connections
be water-tight. The necessary isolation should be provided with impermeable elements against outer space effects after
connections.
In addition, regardless of which air duct is used, it should be regarded that the duct wasn’t made of inflammable or
poisonous gas materials. The inner surface should be smooth and of a nature keeping no dirt.
Isolations shouldn’t let condensations emerge on sheet metal of duct. Connections between ducts should be made in a
flexible manner and shouldn’t let vibrations/ sound formation and/ or transmissions.
20
3.5. Conservation Precautions for the Device from External Air Conditions
Suitable choice of place and placement are required so that the device doesn’t get exposed to External air conditions.
If the device is to operate at an area with high snow fall rate, it should be paid attention to that condenser side of the
device not stay under snow. For that, shelters might be built to distort air flow or precautions could be taken to prevent
snow from accumulating on the surface.
If the device is to operate at an atmosphere close to sea side or with factors to increase corrosion, the heat exchanger
surfaces should be asked to be provided with options preventing corrosion and decreasing water-trap. If this option has
been missed out, necessary precautions should be taken to protect the device from corrosion.
If the area where the device is to be used is an area with a high risk of earthquakes and to get exposed to high speed
winds, it is important that the device is placed away from sides and in the middle.
Besides, if the device has a natural gas firing unit, protecting gas connections against External air conditions and
taking precautions against natural disasters are of the responsibility of users.
Asking the absorption and blow ducts of the device to be provided with rain-proof components will prevent rain and
snow to penetrate the device in long term. Users who didn’t purchase this accessory should protect absorption and
blow ducts of the device. Penetration of snow or water through the device will lead to unwanted results.
The points of URTP device or roof connection element which contact with the ground should be isolated from liquids
according to the details mentioned in 3.3. Liquid penetrations between the device and the ground will lead to both
corrosion of the device and the liquid to reach inner spaces.
3.6. Assemble of Device Accessories
In case the device involves an additional heater (gas, liquid or electric heater), pipe and electricity connections of these
heaters are explained in details in Articles 7th, 8th and 9th. Please pay attention to explanations in the relevant articles
for these connections.
21
3.7. Drainage Connection
In drainage piping, it should be regarded that pipe diameter to be smaller than condensation pan outlet
diameter.
Connection between drainage pipe and condensation pan should be made with union flange so that dirt
occurred in the condensation pan and pipes could easily be cleaned.
Drainage pipe coming out from the condensation pipe should be connected according to the figures below
by using flusher provided with the device.
If drainage piping is long, a declination smaller than 1/50’ should be given to the drainage line.
More than one flush shouldn’t be connected to the same pipe. For these cases, instead of using pipes,
using of ducts open to the atmosphere and separate connections from the flush to this ducts are
recommended.
