Warranty
System description
It is important for any warranty claims is that the customer or his accepting representative fully complete the warranty registra­tion card and commissioning report which is included with the system at the time when it is purchased and commissioned and that these documents are returned to REMKO GmbH & Co. KG. The warranty conditions are detailed in the "Gen­eral terms and conditions". Only the parties to a contract can negoti­ate any special agreements beyond these conditions. In this case, con­tact the contractual partner.
Transport and packaging
The system is shipped in sturdy transport packaging. Immediately check the system on delivery and make note of any damage or miss­ing parts on the delivery note and inform the forwarding agent and your contractual partner.
Warranty claims at a later date will not be accepted.
In cooling mode, the unit (an air to water chiller) takes heat out of the operating medium to be cooled, water or a mixture of water and glycol, within a closed medium cycle in the evaporator (plate heat exchanger) and gives it off to the closed cooling cycle. Through the heat exchange, the medium cools and the refrigerant in the cooling cycle vaporises under low pressure. The vaporised refrigerant passes into an electrically driven compres­sor (rotary piston or scroll design), which increases the refrigerants pressure and temperature. The vaporise refrigerant passes into a finned condenser, which, as a con­sequence of the heat exchange, condenses the refrigerant under high pressure to a liquid. The air that passes through the condenser heats the surrounding area. The liquid refrigerant is returned by means of a thermal expansion valve back to the evaporator where the process starts again.
In heating mode, a chilled water system with heat pump functions (HP-function) can take up heat from the ambient air in the finned condenser and give it off to the operating medium. A reversing valve switches the cooling cycle.
A independent return temperature regulator, which ensures the safety functions of the system controls the cooling and heating. A re­mote Enabling switch provides for remote on/off.
The system is designed for out­door installation. Under certain circumstances, it can also be used indoors. The system’s cooling cycle comprises of: an evaporator, a compressor with a crankcase heater, a thermal expansion valve, condenser, condenser fan, fan speed system and high and low pressure switches. Systems with heat pump function also have a reversing valve and a refrigerant tank. The medium cycle comprises a circulation pump, expansion vessel, safety valve, medium storage tank and a flow switch. Accessories in­clude: Cabled remote control, vib­ration dampers, glycol concentrate and a technical acceptance test.
Intended use
Depending on the model and the equipment, the system is only intended to be used as a chilled water system for the cooling or warming of the operating medium water or a water-glycol mixture within a closed cycle. Any other use or use in a way that dose not conform with the defini­tion above is considered an incor­rect use. The manufacturer/supplier as­sumes no liability for damages aris­ing from the incorrect use of the system or any part of it. The user dose so at their own risk. Using the system correctly means working in accordance with the operating manual, installation instructions and complying with the mainte­nance requirements.

The medium can be circulated to the room to be cooled via the floor, or via the ceiling depending on where the unit is mounted. For each of the different systems, a minimum flow volume and a mini­mum medium volume is needed for safe operation.
NOTE
The escape of refrigerant con­tributes to climatic change. In the event of escape, refrigerant with a low greenhouse poten­tial has a lesser impact on glo­bal warming than those with a high greenhouse potential. This device contains refrige­rant with a greenhouse poten­tial of 1975. That means the escape of 1 kg of this refrige­rant has an effect on global warming that is 1975 times greater than 1 kg CO2, based on 100 years. Do not conduct any work on the refrigerant circuit or dismantle the de­vice - always enlist the help of qualified experts.
Operation
The system can be easily operated via the fully automatic controller μC2SE. If due to local conditions programming via the internal con­trol course difficulties, the system can also be programmed via a ca­bled remote controller (accessory) or an external ON/OFF-Switch.
A centralised fault contact, part of the standard equipment, can be

Installation instructions for qualified personnel
Important information before installing
To install the system it is impor­tant to follow the installation instructions for both the chiller and the chilled water system (indoor system) or heating system when installing the entire system.
The indoor system and the
chiller work independently. A connection between the two is not necessary.
Transport the unit in its original packaging as close as possible to the installation location to avoid damage.
The units may only be moved upright (installed position) using appropriate transport equipment (Figure 1). Secure against tipping!
Lift the unit only at intended lifting points. Never stress the medium or refrigerant pipings.
The medium connection lines, valves and connections must be insulated against vapour density. If necessary, also insu­late the condensate line (only units with HP-function). In dual systems with cooling and heating modes, the requirements of the current or other local law (EnEV) are to be complied with.
Seal off open lines against dirt and never kink or crimp the lines.
Avoid unnecessary bending.
Establish all electrical connec­tions connections in accordance with the relevant DIN- and VDE or other local standards.
In the selection of the installa­tion site, pay attention to the site itself and to any possible noise reflexion from the sur­roundings.
To avoid the transmission of vibrations the units must be installed on vibration absorbing material or on vibration iso­lated foundations. In doing so, make sure that the lines are also vibration isolated.
If the installation site must fulfil special noise emission require­ments, this must be done on site where appropriate adjust­ments can be made. In this cases, please consult a noise level expert.
2 Correct way to lift
Lifting point
The unit must be kept upright when transporting to a higher elevation (Figure 2).
Check that the packaged con­tents are complete and inspect the system for any visible signs of transport damage. Report any damage immediate­ly to your contract partner and the shipping company.
Select an installation location with free air movement both for the inlet and outlet. See section “Minimum clearances”.
Do not install the unit in the immediate vicinity of devices with intensive thermal radia­tion, this will reduce the cooling capacity.
Always fasten electric wiring properly to the terminals, otherwise there is a risk of fire.
Comply with all regulations governing structural and build­ing requirements and conditions with regard to the installation site.
1 Correct way to move

Wall openings
Installation inside buildings
We recommend that the inside of the opening be padded or lined for example with a PVC pipe to prevent damage to the pipe lines
After installation, the wall
.
opening should be sealed off with a suitable sealant. Do not use materials containing cement or lime!
Installation material
The system is secured on vibration absorbers (accessories) to the floor by means of bolts. The carrying ca­pacity of the console and the wall must be taken into account when fastening to the wall.
Selection of the installation location
The unit is designed for horizontal installation on a base in outdoor areas. The installation site must be level and firm. The unit should be secured to prevent toppling. The unit can be installed outside as well as inside a building.
In the case of outdoor installation, please follow the instructions given below to protect the unit against the weather.
Exposure to sunlight further in­creases the temperature of the fins and reduces the heat released by the finned heat exchanger.
The unit should, whenever pos­sible, be installed on the north side of the building.
If necessary, take measures to pro­vide sufficient shade (responsibility of customer).
This can be done by building a small roof covering.
However, the discharging warm air flow must not be affected by this.
Wind
If the system is being installed where it is windy, care must be taken that the discharged warm air (cooling mode) is carried off in the prevailing wind direction. If this is not possible, it may be necessa­ry to install a windbreak on-site (Figure 3).
Ensure that the windbreak does not adversely affect the air intake­to the unit.
Snow
The system should be wall-mounted in areas where there is heavy snow­fall. Mounting should be at least 20 cm above the expected snow level to prevent snow from getting into the system (Figure 4).
Ensure that heat can dissipate adequately when placing the outdoor unit in cellars, attics, adjoining rooms or halls (Figure 5).
Install an additional fan with the same air flow as that of the outdoor unit being installed in the room which can compen­sate any additional pressure losses. (Figure 5, Page 20).
Ensure a continuous and unob­structed air flow from outside, preferably using sufficiently large air openings (Figure 5, Page 20).
NOTE
Cooling or heating perform­ance changes as a conse­quence of the ambient condi­tions influenced by rain, sun, wind, and snow.
Rain
The unit should be at least 10 cm off the ground when mounted on the roof or ground.
For cooling and heating systems (only HP-function) elevated instal­lation increases the heating capacity.
Sun
The finned condenser gives off heat in the cooling mode.

Connection of the medium lines
The connection of the lines on-site takes place on the front side of the unit.
For the purpose of servicing,
connections must be equipped with shut-off valves and valves for hydronic balancing.
Additional automatic bleed valves are to be provided in the supply and return at the instal­lation's highest point.
The medium lines must not
exert any structural load on the unit.
The line connections may not
generate any thermal or mechanical stress on the unit. If necessary, the lines should be independently supported.
If the unit is at first to be operated
with only a part of the entire system, the medium flow volume for the missing system components are to be simulated using the volume control valve.
The pipe size must not restrict
the minimum medium flow.

Minimum/maximum medium flow
The circulating pump generates a constant medium flow; the result is a loss of pressure in the system and in the chiller. The flow switch in the chiller measures the medium pressure loss over the evaporator and switches the unit off if the minimum medium flow is to low. The medium flow limit may not be exceeded (maximum medium flow). A Three-way-valve with bypass and a hydraulic switch to establish a primary and secondary cycle or a volume dependent bypass is nec­essary to ensure a constant flow volume.

A minimum medium volume in the system may not fall below
3.5 l/kW per power stage.

Pressure gauge and thermometer
The pressure gauge and thermom­eter to be installed on-site at the intake and outlet serve to set the medium flow. The display should mean shut down In the system there are temperature sensors in the medium intake and medium outlet. The temperature at the probes can be seen on the controller.
! CAUTION
During use and disposal, product and safety data sheets for the glycol type being used as well as applicable local regulations (e.g. Water Resources Law) must be observed.
! CAUTION
Use the required type and mixture to set the antifreeze setpoint.
Medium lines
Medium lines can be made of cop­per, steel or plastic. To minimise pressure losses, only straight flow through fittings should be used. When designing the layout it must be taken into account, the large flow volumes in the systems, high pressure losses in connection with water-glycol mixtures and the chiller’s minimum medium flow. The lines are to be insulated against vapour density and the current Energy- Savings-Regu­lations (EnEV) or other local law must be observed. UV resistance material must be used outdoors.
Valve for hydronic balancing
The calculated individual pressure losses in the pipeline network layout for each individual unit are adjusted to the entire system with the valves for hydronic balancing to be provided on-site. The nominal flow volumes for the medium adjust to the necessary values as a consequence of the pressure loss.
NOTE
To regulate the circulation pump we recommend a main valve for hydraulic balancing near the unit.
Frost protection (accessories)
As a medium for a chilled water system, a water-glycol mixture is used as a rule. Depending on the use to which the glycol type and quantity is put, the viscos­ity changes, the loss in pressure increases and the unit’s cooling or heating capacity reduces. All sys­tem components must be suitable for use with glycol. As a rule, the addition to the water of ethylene glycol, in a proportion of 34%, with inhibitors for corro­sion protection is recommended.
23
REMKO RVS...H (INOX)
This mixture ensures frost protec­tion to –20°C; at lower tempera­tures, an ice porridge forms which has no more expansion effect. The toxicologically harmless propylene glycol should be used if there is a risk that the medium can come into contact with drinking water or food stuffs. To maintain the expansion effects, a proportion of 38% is necessary as a rule

Air bleeding valves
The unit has manual air bleeding valves. The unit can be vented separately after the system has been filled. Automatic air bleeder must also be installed at the highest point in the collective lines.
Shut-off valves
As a rule, in such systems, shut­off valves (ball valve) with open passages should be used. For the purpose of servicing, medium intake and medium outlet must be equipped with shut-off valves (if necessary safety valves).
! CAUTION
Glycol suitable valves are necessary when using medium that contain glycol.
Fill and drain connection
A connection should be provided in an area safe from frost for the draining of the pipe lines (especial­ly if water is used as a medium). Applicable local disposal regula­tions must be observed if glycol is used.
Dirt trap
A self cleaning dirt trap must be installed on the intake side of the unit. The mesh size should not be less than 10 mesh/cm². Shutoff valves should be installed on both sides of the dirt trap.
! CAUTION
Improperly installed or missing dirt traps can cause fouling of the plate heat exchanger.
External medium storage tank
If, for example, the necessary ca­pacity of the appliance indoor unit is significantly less than the cooling capacity of the chiller, an increase in the medium content is recom­mended. Either the medium lines can be oversized or an additional storage tank installed. A storage tank should, as a rule, be provided if the minimum me­dium volume of the system is not reached.
! CAUTION
A minimum medium volume in the system may mot fall below
3.5l/kW per power stage.
Condensate draining and ensured discharge
Condensate connection
If the temperature falls below the dew point, condensation will form on the finned condenser during heating operation.
A condensate drip pan should be installed on the underside of the unit to drain any condensate.
The condensate drain pipe to be installed on-site must be in­stalled with a in cline of at least 2 % for good drainage. If necessary, fit vapour density insulation.
When operating the system at outdoor temperatures below 4 °C, care must be taken that the condensate line is frost protected. The lower part of the housing and condensate pan are to be kept frost free in order to ensure permanent drainage of the condensate. If necessary, fit supplementary pipe heating.
After completed installation, check that the condensate drainage is unobstructed and ensure that the line is leak tight.

Phase sequence relay FCR (only RVS 100H / RVS 150H)
The phase sequence relay controls the phase sequence of the power supply. The relay will not be acti­vated if the sequence is incorrect.
Fan speed control board A2
To keep noise level to minimum the fans speed can be regulated by adjusting the current. The controller μC2SE calculates the temperature in the condenser over the TR 1 tranceducer. The target value is then adjusted over the fan speed controll board A2.
Probe medium intake B 1
The probe is located at the unit’s medium intake (system return). It serves to monitor the medium tem­perature to regulate the target value.
Probe medium output B 2
The probe is located at the unit’s medium output (system supply). It serves to monitor the medium temperature and regulate the anti­freeze protection temperature.
Probe Condenser B 3
The probe is located at the unit’s condenser. It serves to monitor the condenser’s temperature.

Before
Leak testing
Commissioning
Leak testing is carried out after all the pipes and fittings have been connected.
1. Flush the system twice with water.
2. Clean the sieve insert of the dirt trap provided by customer.
3. Fill the system with water again and vent the system at the manual air bleeder.
4. Adjust the test pressure to 250 kPa (2.5 bar).
5. Check the connections after a pe­riod of 24 hrs for leaking water. If water is visible, the connection has not been secured. Tighten the connection or make a new connection.
6. After a successful leak test, re­move the excess pressure from the medium line. If a water­glycol mixture is used, adjust the non circulating pressure as required.
9 Unit preliminary pressure
Filling the system
The system is filled on-site at the filling and draining connection.
Frost protection for the medium
If a water-glycol mixture is used, it is to be pre-mixed before being put in the system. The desired con­centration is then to be checked.
Unit preliminary pressure for the medium
The preliminary pressure of the medium (without operation of the circulation pump) varies within the system. From the highest point, the pressure increases by approx.10 kPa (0.1bar) per metre difference in altitude (geodetic al­titude). The value measured at the highest point is identified as the none circulating pressure.
The position of the unit in the system is decisive in the calculation of the unit’s preliminary pressure (pressure of the manometer on the unit installed by the customer). The pressure is to be set to at least 70 kPa (0.7 bar).
If the unit is positioned at the lowest point in the system, the unit preliminary pressure (=non-circulating pressure + geodetic system altitude) must be set to at least 70 kPa (0.7
bar) + 10 kPa (0.1bar) x geo­detic altitude.
If the unit is positioned at the highest point in the system, the unit preliminary pressure (=non-circulating pressure) must be set to at least 70 kPa
(0.7 bar).
Please note that the system’s pressure at the lowest point is increased by the geodetic altitude!
Bleeding the system
Air may still be in the pipe lines after the leak test. This is carried during operation of the circulation pump to the next highest point or to the cold water drain. Here it is necessary to vent again (Figure 10).
Also bleed the pump if necessary.
The non-circulating pressure must then be adjusted to the required system pressure.

Expansion vessel
Additional checks
NOTE
The preliminary pressure for the diaphragm expansion vessel must be adjusted individually to the system layout, the volume of the medium and the installed position.
If necessary, change the installed.
For this, the manufacturer’s au-
thorisation is required.
For the cooling and heating
systems, the volume and the
preliminary pressure for the
diaphragm expansion vessel must
be adjusted to both operating
modes; integrate an additional
diaphragm expansion vessel in
the system if necessary.
Valve for hydronic balancing
The pressure in the pipe system
of the individual cold water
outlets can be adjusted at the
valves.
Safety valve
The safety valves must be
checked that they are working
correctly.
The drain line for the valves
are to be checked that they are
clear and leak tight.
General checks
Checking that minimum clear­ances are correct.
Check the outlet possibility of the cooling and heating, for the cold and hot water outlet (indoor unit).
Electrical checks
Checking electrical connections for correct phase sequencing.
Check that the operating contact cooling mode/heating mode works (option).
Check that the enabling contact on / stand-by works (option).
Checking the medium cycle
Check the circulating pump for free flow.
Check that all valves are open.
Check the medium cycle.
Set the circulation pump’s flow volume.
Checking the cooling cycle
The systems are equipped with a phase sequence relay which prevents the operation of the controller if the phrase sequence for the electric mains connection is wrong. The phrase sequence must be corrected if the controller is not activated during commissioning.
NOTE
During manual bleeding, es­caped glycol mixtures must be disposed of separately.
If necessary, change the in-
stalled position.
For this, the manufacturer’s
authorisation is required.
Checking the cooling cycle for adequate oil/coolant.
Check the cooling cycle for leaks.

Commissioning
NOTE
Commissioning should only be Carried out by trained person­nel and after certification to be documented.
Observe the manuals for the
system and all other compo­nents when commissioning the entire system.
Working test for cooling mode
1. Switch the power supply on.
2. Open all shut-off valves if necessary.
3. Switch the system and the cor­responding circulating pump on to the highest stage. The outlet temperature must lie between +4 and +18°C.
4. Switch the unit on and select the cooling operating mode. If the return temperature is warmer than the setting, the compressor display will blink and the compressor will begin to work after approx. 3 to 5 minutes.
5. Please note that the supply temperature at the nominal medium flow lies approx. 5 K below the return temperature.
- If the supply temperature falls below the factory setting of 4°C, a fault signal is triggers. If this is the case, a higher target temperature must be selected. If the spread is too great or too small, the medium flow must be checked.
- The circulation pump starts and the controller checks the medium flow over the flow switch. If the flow is insufficient, a fault shut-down will be carried out and the cooling cycle will not work.
6. Measure and record all the required values in the commis­sioning report and check the safety functions.
7. Check the system control using the functions described in the "Operation" chapter.
Working test for heating mode (only units with HP-function)
1. Switch the power supply on.
2. Open all shut-off valves if nec­essary.
3. Switch the chilled water system and the corresponding circulat­ing pump to the highest stage. The outlet temperature must lie between +35 and +45°C.
4. Switch the unit on and select the heating operating mode. If the return temperature is colder than the setting, the compressor display will blink and the compressor will begin to work after approx. 3 min­utes.
5. Please note that the supply temperature at the nominal medium flow lies approx. 5 K above the intake temperature.
- The circulation pump starts and the controller checks the medium flow over the flow switch. If the flow is insufficient, a fault shut-down will be carried out and the cooling cycle will not work.
6. Measure and record all the required values in the commis­sioning report and check the safety functions.
7. Check the system control using the functions described in the "Operation" chapter.
Final tasks
Reassemble all disassembled parts.
Familiarise the operator with the system.
NOTE
The system is delivered from the factory with all parameters set. If during commissioning it is necessary to change a param­eter it can only be done by authorised personnel.
! CAUTION
During the initialization of the controller (after starting the unit and displaying the soft­ware version, e.g. “H 99”) do not push the key-pad “Prg” to avoid reprogramming the controller!

Ice forms on the fins in heating mode as a consequence of the heat absorption. The amount of ice depends on the percentage of humidity in the ambient air. Under certain cycles and temperature conditions, defrosting cycles are run through in which no heat capacity can be generated. The following reduction fac­tors for the defrosting cycles must be taken into account even when planning the layout:
