POWER SUPPLY MUST BE SWITCHED OFF BEFORE STARTING WORK IN THE ELECTRIC CONTROL BOX 1. GENERAL RECOMMENDATIONS The purpose of this Manual is to provide users with instructions for installing, commissioning, using and maintaining the units. It does not contain the complete description of all the maintenance operations guaranteeing the unit’s long life and reliability. Only the services of a qualified technician can guarantee the unit’s safe operation over a long service life.
4 SYSHRW English 1.3. EQUIPMENT SAFETY DATA Safety Data R407C Toxicity Low In contact with skin Liquid splashes or sprays may cause freeze burns. Unlikely to be hazardous by skin absorption. However, R407C may be slightly irritant and, if liquid, it has a strong degreasing effect. Flush contaminated skin areas with running water. If it comes into contact with fabrics, the liquid refrigerant will cause them to freeze and adhere to the skin.
2. INSPECTION AND STORAGE At the time of receiving the equipment carefully cross check all the elements against the shipping documents in order to ensure that all the crates and boxes have been received. Inspect all the units for any visible or hidden damage. In the event of shipping damage, write precise details of the damage on the shipper’s delivery note and send immediately a registered letter to the shipper within 48 hours, clearly stating the damage caused.

12. HYDRAULIC CONNECTIONS 12.1. RECOMMENDATIONS FOR HYDRAULIC CONNECTIONS 1. t is recommended that all units are connected to a water supply and return pipe system of the Tickelman Loop type. The Tickelman Loop system is self-balancing and thus only requires manual balancing if a large number of units with different flow and pressure loss characteristics are connected to a single hydraulic loop.
English 16 SYSHRW 7. Use steel, copper or P.V.C. pipes for the condensates drainage pipe. Each unit is supplied with a connector for condensates drainage. 8. The condensates drainage line must comprise a siphon and run from the unit on a downward slope of at least 2%. Generally, the siphon is connected directly to the unit’s condensates drainage outlet. A length of plastic pipe can be used between the siphon and the condensates drainage line. A complete condensates drainage system with copper or P.V.C.
4. Formerly, sodium tri-phosphate used to be recommended as a cleaning agent for flushing. However, nowadays numerous countries forbid the introduction of phosphates into their wastewater networks. Therefore, it is now recommended that the system is flushed out with hot water (30 °C). 5. Fill the system again with clean water. Test the water acidity level (litmus paper), and treat as required to obtain a slightly alkaline water quality (pH 7.5 to 8.5).
18 SYSHRW English 12.4. WATER QUALITY The water must be analyzed; the hydraulic network system installed must include all elements necessary for water treatment: filters, additives, intermediate exchangers, drain valves, vents, check valves, etc., according to the results of the analysis. Caution The SYSHRW must not run on a network with open loops, likely to cause incidents related to oxygenation, or with non treated table water.

15.2. ELECTRICAL CONNECTIONS 15.2.1. RCX The RCX control module must be connected in accordance with the diagram below. Use screened twisted pair telephone wire with a section of between 0.12 and 0.5 mm²for wiring the control modules.
24 SYSHRW English 15.2.2. µBMS The µBMS control module must be connected in accordance with the diagram below. Use screened twisted pair telephone wire with a section of between 0.12 and 0.5 mm²for wiring the control modules. Refer to the following chapter for detail of the appliances’ addressing. Caution The use of the µBMS recall command is not compatible with the modbus communication. The same terminals and addressing DIPs are used in both connection cases.

26 SYSHRW English 15.4. RETURN AIR TEMPERATURE MEASUREMENT If the RCX control module is not sited in the air-conditioned premises or is sited at a distance for various reasons, we recommend the use of the Return sensor (RT) located on the appliance itself. To activate the Return sensor (RT) located on the appliance, you just have to cut off the jumper J5 located on of the STORM2 circuit board (Refer to previous paragraph).
SYSHRW 27 English 15.7. RCX ONLY 6 appliances can be connected to a single RCX remote control module. The maximum distance between the RCX and the first unit is 30 metres. The maximum distance between the RCX and the furthest unit is 100 metres. 100 m maximum between the 100m MAXI RCX and the last appliance.
28 SYSHRW English 15.9. MODBUS Caution The Modbus interface, used to communicate with a GTC, is available as an option, factory assembled or with a kit. The MODBUS supervision can be connected to a maximum of 123 appliances. ²²The maximum distance between the RCX and the first unit is 30 metres. ²²The maximum distance between the RCX and the furthest unit is 100 metres. Caution The use of the µBMS recall command is not compatible with the modbus communication.
SYSHRW 29 Caution BEFORE STARTING THE ADDRESSING PROCEDURE YOU MUST MAKE SURE THAT THE UNIT IS SWITCHED OFF AND THAT THERE IS NO POSSIBILITY OF IT STARTING UP UNEXPECTEDLY. Each machine connected to a µBMS central supervision unit or a MODBUS system must receive an address according to the procedure below. Each unit address is selected via the DIP switch SW2 (with 8 selectors).
30 SYSHRW English 15.11. µBMS SUPERVISION MODULE The number of addresses is limited to 15 with a µBMS central supervision unit. The addressing will be performed using only DIP switches 1, 2, 3 and 4. The addressing carried out according to the table below means that all the units located in the same area will receive the same settings.
16. FINAL TASKS Place the plugs back on the valves and check that they are properly tightened. If needed, fix the cables and the pipes on the wall with clamping collars. Operate the air conditioner in the presence of the user and explain all functions. Show him how to remove, clean and place back the filters. 17. STARTING - RECOMMENDATIONS - SETTINGS 1. Check that all the water valves are open and that water circulates in the appliance before making any demand for heating or cooling. 2.
32 SYSHRW English 17.1. COMMISSIONING After performing all the above-mentioned checks, proceed with creating a demand for Cooling and Heating or vice versa. 17.2. DEMAND FOR COOLING and then set the minimum 1. With the MODE key on the RCX control module, select COOL mode temperature with the UP and DOWN arrows. The ambient temperature should be within the operating limits (Refer to "Operating limits").
18. MAINTENANCE AND SERVICING 1. Normal maintenance of the appliances is generally limited to replacing filters. 2. The filters must be changed at regular intervals. The frequency is dependent on the specific application conditions. Certain installations, for example in hotels where there large amounts of fluff due to the frequent bedding changes and the presence of fitted carpets, require more frequent filter changes.
34 SYSHRW English 18.1.3. INSUFFICIENT COOLING OR HEATING PRODUCTION 1. Check that the thermostat is properly located in the zone to be heated or cooled and that it is not near to a source of cold or heat that may influence the reading. 2. Check the proper operation of the Return Air Temperature (RT) sensor, located on the fin exchanger. 3. Airflow is insufficient. Check for clogged filters. Clean and replace as required. 4. The cycle inversion valve may be defective and be creating a refrigerant by-pass.
