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)

118

114

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

1no. 900bends

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

Installation

1. Ensure that the outside wall is clear of any obstructions.

2. Ensure that the selected wall is strong enough to

support the unit.

3. Ensure that no other exhausts will blow directly into the

air inlet duct.

4. Ensure that all hidden cabling/pipework are checked

before any drilling commences.

5. Ensure that fixings are suitable for the application.

6. Do not position the unit directly opposite the airflow

from the main cellar cooler.

Changing Air Spigot Position

Before installation of the unit, follow these steps to change

the position of the air spigot.

1. Remove blanking plate from the bottom of the unit.

2. Unscrew the damper and interchange the damper from

2. Ducting is not provided.

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.
