1. Important Recommendations

• VB Series air cooled condensers are intended for installation only by Qualifi ed Refrigeration Personnel and are to be installed in accordance with the guidelines mentioned in this manual.

• All electrical work is to be carried out by Qualifi ed Electrical Personnel and to be in accordance with local electrical regulations.

2. Safety Recommendations

• Condensers are supplied with a Nitrogen Holding Charge. (Release pressure fully before accessing the connection points).

• Electrical power to be isolated prior to the commencement of any electrical work. • During normal operation Pressurised Refrigerant is contained within the condenser. • Extreme care should be taken to avoid leakage, as personal injury may occur. (Avoid the use of sharp

objects in close proximity to refrigeration piping).• Extensive gas loss in enclosed area may result in asphyxiation.• Contact with refrigerant may cause personal injury. (Freeze Burns).

• Normal operating conditions involve hot surfaces within the condenser. Extreme care should be taken to avoid contact

• Avoid contact with condenser fi ns as sharp edges may cause personal injury.• Insertion of any object into condenser fans is to be avoided as this may result in personal injury and/or

equipment damage.• Operating sound pressure levels may cause discomfort. Refer to catalogue for calculated sound levels.

3. Application Ranges• These condensers are intended for use in Commercial Refrigeration systems with a maximum operating

ambient temperature of approximately +60°C. (Special designs available on application)• Recommended refrigerants: HFCs, HCFCs. (Also suitable for CFCs)• This series of condenser is not suitable for use with NH3. (Ammonia), r744 (CO2). • Standard condensers are not to be installed in hazardous/combustible environments. (Special designs

available on application)

Recommended Clearances (table 3)

Please note:A clearance at each end of the condenser for practical purposes is recommended, a minimum distance of 750mm. For alternative condenser deck arrangements, please contact BITZER Australia.

Lifting

Lifting lugs are fi tted to each condenser and each have a Working Load Limit (W.L.L.) of 900kg as per Certifi cate of Test and Examnination, Certifi cate No. 45479. For Dimensions please refer to Table 4 as per below.

• Remove the condenser from its crate or skid using an appropriate lifting device (refer Figure 3 for recommended lifting methods)

• Place the condenser into the installation position and secure using the mounting holes as per Figure 1 or 2.

• Please Note: Minimum diameter of fi xing bolts is to be 9.525mm (⅜”)• The use of lifting devices during installation is recommended where applicable.• Observe recommended condenser mounting locations as per Figure 1 or 2.• Ensure the condenser is installed level, to avoid liquid locking within the condenser.• Refrigeration piping connections should be carried out in accordance with the current “Refrigeration Code

of Good Practice”*. (Beware of HOT surfaces present during the welding procedure).• Refer to Figure 1 or Figure 2 for refrigeration piping connection points.

7. Electrical Connections

• Fan motors comply with DIN EN 60 043-1 (VDE 0530 Part 1) and suitable for 3PH 400 Volt ±10%,∆ /Y 50 Hz. Operation.

• All three phase motors are pre-wired for high speed operation to an independent isolation switch within an IP56 rated electrical junction box mounted on the condenser.

• Please see FIG. 4 for High Speed / ∆-Delta connection.• Please see FIG. 5 for Low-Speed / Y-Star connection.

Please refer to the following fan manufacturer’s recommendations:

“The temperature monitors (TB) or PTC resistors built into the winding serve as the motor protection and must be connected to a manual reset device to prevent automatic restart after thermal excursion. Motor damage caused by excessive temperature in the fan motor due to not connected thermal contacts is not covered under warranty.

Axial fans are suitable for operation with frequency inverters when the following points are complied with:• Between the inverter and the motor, sinusoidal fi lters should be incorporated which are eff ective for all

phases (sinusoidal output voltage, phase against phase, phase against protective conductor) as off ered by manufacturers.

• du/dt fi lters (also called motor or suppression fi lters) cannot be used in place of sinusoidal fi lters.• In case of speed control by voltage reduction (phase cutting), increased noise may be caused by

resonance depending on the mounting position and location. We recommend the additional installation of a noise fi lter.

• We cannot guarantee that competitive makers of voltage control devices and frequency converters will function properly and not damage the motors when used for rotational-speed control of our Fans.

• The operation with frequency inverter is limited to 50 Hz on 400Volt supply. Operation above these limits may cause a reduction in fan motor effi ciency and an increase of internal motor temperature which may aff ect performance and motor life.

• For further fan information please refer to the enclosed Fan Operating instructions or contact BITZER Australia.

EC-BLUE Single and 3 Phase Fan Motor(s) & Controls

Setting of fan conditions using “AM-CONFIG”

AM-CONFIG is the “plug and play” controller available to suit the EC-Blue. As default the fans are supplied to receive a 0-10V input signal and operate to 0-1100rpm. Common setup features are accessible using this device. See manufacturer’s operating instructions for more information.

8. COMMISSIONING INSTRUCTIONS

• Leak testing should be carried out in accordance with the current “Refrigeration Code of Good Practice”*.

• Following leak testing, the system should be evacuated using accepted refrigeration practices. The vacuum pump should be connected to both the high and low pressure sides of the system with all shut-off valves open. Refrigerant charging should be carried out in accordance with the current “Refrigeration Code of Good Practice”*

• Extreme care should be taken to avoid direct contact with liquid refrigerant. (Freeze Burns)• Ensure the electrical wiring is in accordance with local electrical regulations and ensure fan motor direction

is correct.

9. MAINTENANCE INSTRUCTIONS

• Buff alo Trident condensers require low maintenance, apart from regular cleaning of the fi n face. Frequency is dependent upon the operating environment of the condenser.

• It is recommended that fi n surfaces are cleaned using a soft bristle brush and/or low pressure water, taking care to avoid all electrical components. (Electrical power must be isolated prior to cleaning)

All fan motors contain bearings and are maintenance free.

10. DE-COMMISSIONING INSTRUCTIONS

• Pump down refrigeration system into the receiver or suitable container. (As per “Refrigeration Code of Good Practice” *)

• Isolate power and remove electrical wiring (remove earth wire last) and associated components where necessary.

• Disconnect refrigeration piping and seal both the system and condenser connections. (Ensure that positive/negative pressure does not exist in condenser prior to disconnection)

• Condenser can now be removed from location. (The use of lifting devices during removal is recommended where applicable)
