1. Important Recommendations
• BDC air cooled condensers are intended for installation only by Quali󰘰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 Quali󰘰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 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 󰘰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), 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 󰘱ow.
a) Mounting - Vertical Air Flow
• Remove the condenser from its crate.
• Vertical air 󰘱ow condensers are shipped without legs 󰘰tted.
• 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 air󰘱ow condensers are shipped with mounting feet 󰘰tted in 󰘰nal 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 󰘰xing 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-
o󰘯 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
• Bu󰘯alo Trident condensers require low maintenance apart from regular cleaning of the 󰘰n face.
Frequency is dependent upon the operating environment of the condenser.
• It is recommended that 󰘰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.
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.
