• Refrigerants have a narcotic effect when inhaled in high concentrations. • I f unavoidable work is required in the presence of a high concentration of refrigerant, breathing apparatus must be worn. This does not mean simple filter masks. Comply with breathing protection data sheet. • Do not eat, drink or smoke at work. • Warning against intentional misuse. • It is absolutely essential to comply with the first aid measures if accidents occur. • R efrigerants containing FCs contribute to the global warming and with this to climate changes.

Page 7: Duties Of The Operator
The operator is responsible for the execution. The operator must ensure that all maintenance, inspection and assembly work is carried out by authorised and qualified specialist staff who have made an in-depth study of the operating instructions. independent conversion and manufacture of replacement parts The system may only be converted or modified after consultation with STULZ. Original replacement parts and replacement parts/accessories authorised by STULZ are an aid to safety. © STULZ GmbH – all rights reserved EN/06.2018/G42...
Page 8: Transport / Storage
• You receive the consignment papers with the delivery of the chiller unit. • The shipment is made ex works, in case of shipment damages, please assert your claim towards the carrier. 2.2 Storage If you put the unit into intermediate storage before the installation, the following measures have to be carried out to protect the unit from damage and corrosion: • t he storage point must not be exposed to direct sunlight. Observe the storage conditions in the chapter “Application limits“. • store the unit packaged to avoid the risk of corrosion. • m ake sure that the water connections are provided with protective hoods.

HP switch (high pressure limiter) When the HP limiter triggers, the compressor is switched off without delay. Before the restart and after the elimination of the error, the HP switch must be reset by pressing the red reset button. A check of the tripping function of the high pressure limiter (e.g. by cutting down the condenser fan and forc- ing a high pressure) is not possible without difficulties, as there are, on behalf of the C7000 controller, further monitoring functions via the high pressure sensor, which intervene in the compressor control (high pressure management). LP switch Check the correct function of the low pressure switch by stepwise closing the expansion valve of one refriger- ant circuit using the manual mode of the C7000 controller, while the compressor is running. Check by means of a pressure gauge connected at the low pressure side in the compressor section, whether the low pressure switch trips at 3 bar. When the LP switch trips, the compressor is switched off without delay. After the compressor pause (default setting: 180 sec.) has elapsed the compressor is restarted. During the evaluation delay (default setting: 120 sec., possibly raise on 300 sec.) you can stepwise open the expansion valve in manual mode, until you reach a suction pressure of 6 bar (check by suction pressure gauge). © STULZ GmbH – all rights reserved EN/06.2018/G42...

The interaction between ester oil and water results in the formation of acid. Owing to a hyperacidity, corrosive processes take place inside the compressor. • In this case exchange the ester oil. Oil level During unit idleness the oil level should not be below the lower quarter (bottom line) and not rise above the upper line during operation. Oil type: ICI Emkarate RL 32-3MAF (factory filling) ICI Emkarate RL 32 CF • C heck the oil level by looking at the sight glass in the oil compensation line (for size 3/4 directly on the compressor). Crankcase heater Check the crankcase heater function by measuring the ohmic resistance at the terminals of the auxiliary con- tactor in the electric cabinet. For the 140W heater the ohmic resistance should approximately be 1,1 kOhm, 1,3 kOhm for the 120W heater and 1,8 kOhm for the 90W heater. EN/06.2018/G42 © STULZ GmbH – all rights reserved...

The detergent "Snowclean marine SP" is highly concentrated and must be diluted with water. This detergent is aggressive towards painted, varnished and anodized aluminium surfaces! For coated finned heat exchangers and microchannel coils, we recommend a cleaning with just warm water without using chemicals. The detergent "Snowclean marine SP" would damage the coating. Procedure • first clean the coil with a vacuum cleaner and soft nozzle. • rinse from the inside out and from bottom to top. • direct the jet of water always vertically on the fins, to not distort the fins. • allow the detergent to react on the debris about 1-5 minutes, but do not let it dry. For rinsing, we recommend to use a high pressure washer with hot water of 50-80 °C. Rinsing with cold water is less effective. • rinse all wetted surfaces thoroughly. • rinse the debris from the inside out and from bottom to top, until the exiting water is completely clean. • d rain the water which has accumulated between the coils (sizes 5-7) by removing the plugs at the bottom plate. We accept no liability for consequential damages and improper application. © STULZ GmbH – all rights reserved EN/06.2018/G42...
Page 70 The electronics housing can get hot. The fans have an operation delay after the unit is stopped ! You need an appropriate secured access (e.g. working platform) to the chiller top, to dismount a condenser fan for each heat exchanger element. • open the centrally located cable duct on top of the chiller. The duct is divided into a part for the power lines and a narrower part for control lines. The fan is connected by a screwed plug connection in the power line part and two screwed plug connections in the control line part. • disconnect the electrical connections and protect them against damage and humidity. • completely unscrew the 4 Torx screws of the fan grille • lift the fan (weight: approx. 30 kg) with another person and place it upside down on a fan next to it.

Another possibility to verify this consists in the comparison of the chilled water outlet temperature with the saturated evaporation temperature (by measuring the suction pressure at the low pressure side of the com- pressor). If this difference exceeds 7 K, the evaporator is probably polluted. In this case the evaporator has to be cleaned chemically. Frost protection sensor Flow sensor Water outlet temperature sensor Water inlet temperature sensor Chilled water sensors Pump (option) The pump is equipped with permanently lubricated bearings. According to the manufacturer's instructions, the bearings have an expected durability of 20,000 operating hours. • check the pump for audible and visible wearing. • replace the bearings with noticeable wearing. • f or instructions on how to replace the bearing see QR-code on the pump or instruction sheet in the e Stulz area. © STULZ GmbH – all rights reserved EN/06.2018/G42...

At the fan contactor, dangerous voltages occur. Do not open the unit within the first 5 minutes after disconnection of all phases. Due to the EC fans dangerous charges of >50µC can occur for a short time between AC line terminals and PE after disconnection. Electrical box • c heck the connection terminals for tight fixation when the unit is installed and once again after an operation time of 30 days. CAUTiOn The power contactors of the compressors must be checked on smooth operation and worn contacts every 10 years. Unit interior Clean pipes simplify the search for leaks. Vibrations of pipes and circuit components can result in leaks. • check the pipes for a tight seat. Condensing air humidity on cold water pipes means a loss of cooling capacity. • check the insulation of the water piping. EN/06.2018/G42 © STULZ GmbH – all rights reserved...
