Product Features
The JABC-1 is primarily used for cooling beer cellars. Cold
air is drawn from outside by the fan through the washable
air filter and distributed into the cellar space. The unit
consists of a fan motor, washable filter, controllers, air
damper, and a pre-wired electrical control box all housed
within a powder coated steel casing.
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
being positioned outside by the air intake grille and the
cellar probe being positioned in a suitable position within
the cellar space (ideally by the main cellar cooler
temperature sensor).
Details of the product:
•Refrigerant free –environmentally conscious
•Washable/reusable air filter
•EBM fan motor with multi-speed capability –can be
adjusted to suit room size
•Interchangeable air inlet damper location –either rear
or base mounting
•Uses standard 150mm diameter ducting
•Fully pre-set controllers
•Inbuilt timer to allow cellar cooler to run for 1 hour per
day (winter operation)
•Switching relay allows operation with all types of
cellar coolers

Operation
The JABC unit is designed 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 –passing
through the air filter and cooling the space until the set
temperature of 10°C is reached. If the cellar temperature
continues to rise with the JABC unit running, at 13°C the
main cellar cooler unit will cut in and run along with the
JABC to provide additional cooling 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 designed to be the main control for the
cellar temperature, utilizing both external air when
available and the main cellar cooler as required. The main
cellar cooler controller should be set to the same operating
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 during
winter periods.

Health and Safety
General information
Before Installation
•On receipt of the product, all items should be visually
inspected, and any damage or shortage should be
advised to the supplier immediately.
•Ensure that the correct voltage supply is available for
the unit requirement. Damage to electrical components
within the unit will occur if this is not observed.
•Check that the proposed equipment location is suitable
and provides adequate support for the weight of the
unit.
•Check the proposed equipment location for mains
services (gas, electric water etc.) before drilling holes
for ventilation duct and unit fixings.
•If using external ducting arrangement, ensure ducting
route will fall within the limitation of pressure resistance
as listed in Table 5.
During Installation and subsequent maintenance
•Installation and maintenance are to be performed only
by qualified personnel who are familiar with local
codes and regulations and experienced with this type
of equipment.
•If lifting equipment is required, ensure that it is suitable
for purpose, certificated and that the operatives are
qualified to use it.
•Safe working methods are identified, and operators
have suitable Personal Protective Equipment (PPE).
•Ensure the working area is clear of obstructions.
•The units contain moving parts and electrical power
hazards, which may cause severe injury or death.
Disconnect and shut off power before installation or
service of the equipment.
•Units must be earthed.
•The electrical covers and fan guards must remain fitted
all the time.
•Use of the units outside of the design conditions and the
application for which the units were intended may be
unsafe and be detrimental to the units, regardless of
short- or long-term operation.
•The units are not designed to withstand loads or stress
from other equipment or personnel. Such extraneous
loads or stress may cause failure or injury.
Air Flow Calculations
For effective operation, the cellar will require between 6 to
10 air changes per hour. To calculate the fan speed setting
needed to achieve the required air change:
•Calculate room volume in m³ (L x W x H)
•Multiply the resulting room volume by a value between
6 and 10 (air changes/hour) to achieve a required
figure in m³/h.
•Check the figure against the airflow values (m³/h) for
the fan given in Table 1 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 facing wall (through-
wall installation). If an external facing wall is unavailable,
the JABC unit can be mounted in a suitable location, with
the air inlet connection changed to bottom entry. This is
done by exchanging the rear inlet spigot with the bottom
entry sealing plate for ducting purpose. Refer Page 3for
instructions on how to change the inlet spigot position.
When connecting ducting to the JABC unit, it is
recommended that any increase in pressure resistance
should be limited as follows:
Table 5: Maximum Air Pressure Resistance
Fan Speed
Maximum Pressure Resistance (Pascals)

90
3
118

60
For 150mm nominal diameter lightweight ducting, the
following standard industry values could be used to
calculate the pressure resistance for the proposed ducting
run:
Table 6: Pressure Resistance for Ducting
150mm Circular Duct
Pressure Resistance (Pascals)
1 metre straight length
7
1no. 900bends
15
1no. 450bends
7.5
Example calculation:
Room volume is 6m x 5m x 2.4m (72m³). Multiply this figure
by 8 (air changes/hour). This gives a required figure of
576m³/h.
Refer Table 1, either fan speed 3 or 4 will give the
required airflow to achieve 8 air changes per hour.
Installation requires: 6m of straight ducting, 2no. 900bends
and 2no. 450bends
Calculation : (6 x 7 Pascals) + (2 x 15 Pascals) + (2 x 7.5
Pascals) = 87 Pascals
Assessment: Refer Table 5, 87 Pascals resistance is within the
limits of the fan at either fan speed 3 or fan speed 4.
Room Air Balance
As the unit can provide up to approximately 700m³/h of
airflow into the cellar, this will need to be balanced by
allowing air outlet from the room. This can be done by
fitting an air grille in the cellar door (provided in the
optional installation kit) or by other means.
Fan speed 1 should only be used for
through-wall applications with small room
sizes. For extended ducting application, we do
not recommend using the unit with fan speed 1.
Regardless of room size, please select either fan speed 2,
3 or 4 only.

Issue: 01.06.2023 Page 3

Figure 6: Spigot Positions
Electrical Connection
The mains electrical supply to the JABC-1 unit
must be via a suitably rated isolator and
circuit breaker or fuse. There is no isolator
fitted to the unit. It requires a 230 volt / 1
phase / 50Hz supply which must include a
Neutral and Earth. It is not suitable for any other supply
voltages (other than a deviation of +/- 10% of the above
values) and is not suitable for 60 Hz supplies.
1. Ensure that all power supplies have been isolated
before starting any electrical work.
2. Only a qualified electrician should carry out any
electrical work.
3. Ensure that indoor cellar unit is fully isolated before
carrying out this section.
4. Make sure that the supply to the JABC-1 unit and the
control circuit from the main cellar cooler are using the
same electrical phase, otherwise there is potential for
400V at the JABC-1 unit.
5. Where the main cellar evaporator has only one fan,
this should be wired to run continuously (whether the
JABC-1 unit is running or not) to maintain proper air
circulation within the cellar. For evaporators fitted with
multiple fans, it is possible to leave one fan running
and switch additional fans off for energy saving when
not required (cellar at desired temperature) through
relay K2R on the JABC-1 unit. This may require a
wiring change to the fans on the evaporator.
6. Maximum allowable load to relay K2R is 1250VA
(Resistive: 5A/250VAC; Inductive 1.5A/250Vac).
Probe Positioning
•Cable glands are provided for the mains supply cable
and the cellar temperature probe cable on the right-
hand side of the unit. Use the provided M12 cable
gland for the mains supply cable and the cellar
temperature probe.
•The cellar temperature probe is coiled up in the control
box. Remove the front lower panel on the unit to gain
access to the control box.
•The ambient temperature probe is coiled and stored
behind the air damper on the rear of the unit.
•Connect the mains supply cable (provided) to the unit
as per the Figure 8: Wiring Diagram. Do not switch on
the supply yet.
•Isolate the main cellar cooler supply and break the
control circuit as per the wiring diagram. Using a 2-
core cable, connect the control circuit from the main
cellar cooler to terminal A on the JABC unit and return
via terminal B to feed either the main cellar cooler
contactor coil or the solenoid valve.
•Position the JABC cellar temperature probe unit in a
suitable position within the cellar (ideally next to the
temperature sensor for the main cellar cooler). The
probe cable length is 3m, but this can be extended
with 2 x AWG22 if required.
•Position the JABC ambient temperature probe. This can
be run down the inside of the air inlet ducting and
secured within the external air inlet grille. Ensure sensor
is protected from direct sunlight which may affect the
temperature reading and the operation of the unit.
Commissioning
•Ensure that all covers are fitted on the unit.
•Ensure that all electrical connections have been
made as per Figure 8: Wiring Diagram
•The controllers are fully preset and the settings
should not be altered.
1. Switch on power supply to both main cellar unit and
JABC-1.
2. The JABC-1 unit should now display outside ambient
temperature on the Ambient controller (top) and the
cellar temperature on the Cellar controller located
below.
3. The cellar temperature set point of the JABC-1 unit is
preset to 10°C. This must not be altered.
4. The temperature set point of the main cooling should
be set at 10°C to match the JABC controller or it can
be set 1°C lower than JABC-1 setting if required. The
set point of the main cellar cooler should not be set
above 10°C.
5. Allow the system to run and ensure that the unit is
functioning correctly.
There are 2 external status lights on the front of the JABC-1
unit giving a clear visual display of current operating
condition of unit.
