The JABC-1 is primarily used for coolin beer cellars. Cold air is drawn from outside by the fan throu h the washable air filter and
distributed into the cellar space. The unit consists of a fan motor, washable filter, controllers, air damper, a pre-wired electrical
control box all housed within a powder coated steel casin . Operation is via two electronic temperature controls – one an ambient
controller and the other a cellar controller. Each controller has one temperature probe – the ambient probe bein positioned outside
by the air intake rille and the cellar probe bein positioned in a suitable position within the cellar space (ideally by the main cellar
cooler temperature sensor). This uideline enables users to ensure correct and safe installation, operation and maintenance of this
product.

6. Operation
The JABC unit is desi ned to operate when the external ambient temperature is 8°C or below and the cellar temperature rises
above its setpoint of 10°C. The JABC fan motor will draw external cool air into the cellar – passin throu h the air filter and coolin
the space until the set temperature of 10°C is reached. If the cellar temperature continues to rise with the JABC unit runnin , at 13°C
the main cellar cooler unit will cut in and run alon with the JABC to provide additional coolin until the setpoint temperature is
reached. At this point, both the JABC and the main cellar cooler will cut off. The JABC unit will not operate if the external ambient
temperature is above 8°C. At external ambient temperatures of above 8°C, only the main cellar cooler system will operate.
The JABC unit is desi ned to be the main control for the cellar temperature, utilizin both external air when available and the main
cellar cooler as required. The main cellar cooler controller should be set to the same operatin temperature as the JABC unit.
An inbuilt timer within the controller allows the main cellar cooler to run for one hour every 24 hours. This ensures that the main cellar
cooler will still run durin winter periods.

8. Air Flow Calculations
For effective operation, the cellar will require between 6 to 10 air chan es per hour. To calculate the fan speed settin needed to
achieve the required air chan e:
•Calculate room volume in m³ (L x W x H)
•Multiply the resultin room volume by a value between 6 and 10 (air chan es/hour) to achieve a required fi ure in m³/h.
•Check the fi ure a ainst the airflow values (m³/h) for the fan iven in Section 4 on pa e 4 and select the fan speed which
best matches this.
The JABC unit comes with a rear entry air inlet connection for direct attachment to an external facin wall (throu h-wall installation).
If an external facin wall is unavailable, the JABC unit can be mounted in a suitable location, with the air inlet connection chan ed to
bottom entry. This is done by exchan in the rear inlet spi ot with the bottom entry sealin plate for ductin purpose. Please see
pa e 7 for instructions on how to chan e the inlet spi ot position.
When connectin ductin to the JABC unit, it is recommended that any increase in pressure resistance should be limited as follows:
Fan Speed
Maximum Pressure Resistance (Pascals)
4
90
3
118
2
114
1
60
For 150mm nominal diameter li htwei ht ductin , the followin standard industry values can be used to calculate the pressure
resistance for the proposed ductin run:
150mm Circular Duct
Pressure Resistance (Pascals)
1 metre strai ht len th
7
1no. 90 de ree bend
15
1no. 45 de ree bend
7.5
Example calculation:
Room volume is 6m x 5m x 2.4m (72m³). Multiply this fi ure by 8 (air chan es/hour). This ives a required fi ure of 576m³/h. Either
fan speed 3 or 4 will ive the required airflow to achieve 8 air chan es per hour.
Installation requires: 6m of strai ht ductin , 2no. 90 de ree bends and 2no. 45 de ree bends
Calculation: (6 x 7 Pascals) + (2 x 15 Pascals) + (2 x 7.5 Pascals) = 87 Pascals
Assessment: 87 Pascals resistance is within the limits of the fan at either fan speed 3 or fan speed 4.
lease Note:
Fan speed 1 should only be used for throu h-wall applications with small room sizes. For extended ductin application, we do not
recommend usin the unit with fan speed 1. Re ardless of room size, please select either fan speed 2, 3 or 4 only.
