RLC-SVX03A-E4 9 Installation r esponsibilities Generally , the contractor must do the following when installing an R TUB/RTCA unit. • Install the units on a flat foundation, level (within 1/4" [6 mm] across the length of the unit), and strong enough to support unit loading.
10 Special Lif ting and Moving Instr uctions A specific lifting method is recommended as follows: 1 . F our lifting points are built into the unit. 2. Slings and spreader bar to be provided by rigger and at tached to the four lifting points.
11 Installation condensation coils must be protected from side winds when their speed exceeds 16 km/h. P osition the unit above the average height of snow observed in the region where it is installed.
12 Drainag e Pro vide a large-capacity drain for water vessel drain-down during shutdown or repair . The evaporator is provided with a drain connection. All local and national codes apply . The vent on the top of the evaporator water bo x is provided to prevent a vacuum, by allowing air into the evaporator for complete drainage.
13 Follow the manufacturer's instructions for the installation procedures. Flow S witch Installation 1 . Mount the switc h upright, with a minimum of 5 pipe diameters of straight horizontal run on eac h side. Do not install close to elbows, orifices, or valves.
14 Installation the values given by the pressure gauges, open one valve and close the other . Refr iger ant Saf ety V alv es Disc harge valves are an option for the R TUB.
15 Installation withstanding high temperatures without degradation. C C A A U U T T I I O O N N A defect in fixing or insulating the condensation sensors may cause incorrect adjustment and/or damage to the compressor .
16 another manufacturer's condenser in used, operation and performance may be degraded. Depending on the fan settings, malfunctioning may damage the R TUB due to instability of the high pressure.
17 Installation 1 2 Figure 1 1: Units on the same level Limitations: The distance between the two units must not exceed 60 m in reality or the equi valent of 90 m taking into account pressure drops. The height of the liquid line in relation to the unit base must be less than 5 m.
18 Installation 3 Figure 13: RTCA (or other manuf actur er's condenser) below the RTUB Limitations: The distance between the two units must not exceed 60 m in reality or the equi valent of 90 m taking into account pressure drops. The height of the liquid line in relation to the condenser base must be less than 5 m.
19 Equiv alent pressur e drops T o cor rectly determine the size of the liquid and disc harge lines for connection on site, it is first necessary to establish the equivalent pressure drops for eac h line, comprising the additional flow resistances, from bends, valves, etc.
20 V acuum pumping For this operation, use a vane pump making it possible to obtain a partial vacuum or 1 0 0 microns or less. When pumping out to create a vacuum, it is important to connect the pump to the high and low pressure sides of the system. Follow the pump manufacturer's recommendations.
21 Pr e-start chec k out Installation Checklist When installation is complete, but prior to putting the unit into service, the following pre-start procedures must be reviewed and verified: • Inspect all wiring connections to be sure they are clean and tight.
22 Oper ation motor rotation requires confirmation of the electrical phase sequence of the power supply . The motor is internally connected for cloc kwise rotation with the incoming power supply phased A-B-C. When rotation is cloc kwise, the phase sequence is usually called "ABC;" when countercloc kwise, "CBA.
23 operating load. Overheating may vary slightly on the circuit if the system load is lower , when the slide valve is moving. Overheating must stabilize at approximately 4°C when the abo ve components have stabilized. Subcooling Normal subcooling for eac h circuit ranges from 8-1 0°C, depending on the units.
24 Oper ation System Flow R ates" and "W ater - System P ressure Drop." 7 . Adjust the flow switch on the evaporator piping for proper operation. 8. Stop the water pump. The unit is now ready for startup as described in "Startup P rocedures.
25 P erform all maintenance procedures and inspections at the recommended intervals. This will prolong the life of the c hiller and minimize the possibility of costly failures.
26 For units without disc harge v alve option 1 . Shut of f the compressor and disconnect all electrical service to the compressor . 2. V acuum the refrigerant out of the circuit. 3. Remo ve the seven bolts on the oil filter cover . A pan may be necessary to catc h any oil that is released after the co ver is loosened.
27 Follow the steps listed below and refer to the notes listed in Figure 17 . 1 . T urn of f the unit. 2. Attac h the hoses and sight glass to the oil-separator Sc hrader valves, as shown in Figure 17 . Remove non-condensables. 3. After the unit has been of f for 1 0 minutes, move the sight glass up and down until the level can be seen.
28 Some symptoms of an oil under - char ged unit: • Compressor rattle or grinding sound • Lower -than-normal pressure drop through oil system • Seiz ed or W elded Compressors • Low oil-sump le.
29 The evaporator is large enough to hold all the c harge, for any unit, below the centerline of the shell. Therefore, no special precautions are required to restart the unit af ter isolating the c harge in the evaporator .
30 F actory (initial) Oil-Charging Procedur e The initial c harging procedure should be followed any time the unit is new or has had all of the oil removed. 1 . Add 0.95 liter (0.90 k g) of oil to the motor cavity or suction line prior to installing the compressor into the c hiller .
31 and oil- line shutoff valve, without the need to pull a vacuum on this small volume. If the oil has been in an open container or is otherwise contaminated, then this small volume must be subject to vacuum as well. However , the filter cavity is full of oil.
