BDC Series Air Cooled Condensers

Models: BDC 152 (2F) (V) BDC 152 (2F) (H) BDC 456 (6F) BDC 228 (3F) (V) BDC 228 (3F) (H) BDC 608 (8F) BDC 304 (4F) (V) BDC 304 (4F) (H) BDC 760 (10F) BDC 380 (5F) (V) BDC 380 (5F) (H)

1. Important Recommendations

• BDC air cooled condensers are intended for installation only by Qualified 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 Qualified 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 is 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 fins 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), R410a or R744 (CO2).• Standard condensers are not to be installed in hazardous/combustible environments.

4. Installation Guide The BDC Series of Air Cooled Condensers are suitable for Vertical and Horizontal air flow.

a) Mounting - Vertical Air Flow

• Remove the condenser from its crate.• Vertical air flow condensers are shipped without legs fitted.• Legs are supplied within each BDC Series condenser crate.• Using an appropriate lifting device (refer Figure 1 for recommended lifting methods), attach the legs to the condenser using the bolt kit supplied.• Place the condenser into the installation position and secure using the mounting holes located in the legs.

b) Mounting - Horizontal Air Flow

• Remove the condenser from its crate.• Horizontal airflow condensers are shipped with mounting feet fitted in final position.• Using an appropriate lifting device (refer Figure 2 for recommended lifting methods).• Place the condenser into the installation position and secure using the mounting holes located in the feet.

NOTE:

• Minimum diameter of fixing bolts is to be 12.70mm (½”)• The use of lifting devices during installation is recommended where applicable• Observe recommended condenser mounting locations as per Figure 2.1, parts 1 and 2• Remove the transport brackets from the BDC Series condensers (vertical only)• 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).

* Avoid horizontal air discharge installation where prevailing wind would create additional static load on fans, especially at low fan speeds (< 680 RPM)

5. Electrical Connections

• EC Fan motors are suitable for 400 Volt ±10%, 50 Hz operation.• All three phase motors are pre-wired to an independent isolation switch within an IP56 rated electrical

junction box mounted on the condenser.• These motors are to be wired in accordance with Fig. 3 (wiring diagram R55000117 shown over the page).

7. 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.

8. Maintenance Instructions

• Buffalo Trident condensers require low maintenance apart from regular cleaning of the fin face. Frequency is dependent upon the operating environment of the condenser.

• It is recommended that fin 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.

9. 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).

* Code of Good Practice produced in conjunction with AFCAM.
