Cabinet Layout
VISAIR+ CABINETS - OPERATION
Visair Cube
This is a stand-alone, open fronted cabinet,
with glass side panels and a top fluorescent
light.
Various shelf configurations are available to
accommodate different package sizes.
Cabinets are fully self-contained, with an
integral refrigeration unit. They are fitted
with a condensate disposal pump, which
can either discharge into a drain or a rear
mounted condensate boil-off unit.
The controls and refrigeration equipment
are mounted in the base of the cabinet.
Cooling air for the refrigeration system is
drawn in from the top of the cabinet, where
the air is cleaner than at floor level.

Preparation
VISAIR+ CABINETS - OPERATION
Shelf Location
and Ticketing
All shelves are adjustable in height and can easily be moved up or down, to
match product size. The front edges of the shelves are profiled to carry
ticketing/labels.
Shelf
Adjustment
To alter the shelf position, slide the brackets
upwards and disengage them from the
support pillar.
Insert the brackets in the new position and
push them down firmly.
The brackets can be inserted in two
positions, allowing the shelves to be either
horizontal or sloping downwards.
Make sure shelf brackets are pushed down as far as they can go. Failure to do
this may result in shelf collapse, when loaded with product.
Shelf Loading
Position
Each shelf is fitted with runners,
enabling it to be pulled forward for easy
loading.
Using two hands, depress the two
locking bars located under the front
edge of the shelf, to release it.
When returning the shelf to its normal
position, push it in firmly, until both
locking bars latch into position.

Preparation cont.
VISAIR+ CABINETS -OPERATION
Switch Power
On
Turn on the power switch, the compressor will
run, and the cabinet temperature will begin to
fall.
The temperature controller is pre-set to maintain
the cabinet temperature at 2- 4C. It should
not need adjustment.
Load Cabinet
After the cabinet has run for a 30 minute initial cool-down period, load it with
pre-chilled product.
The cabinet is designed to maintain the temperature of pre-chilled product at
between 2and 4C.
If warm product is introduced, there could be a delay before the
temperature falls to the normal operating level.
Air Baffle
Plates
If low profile products are displayed on any shelf,
fit an air baffle plate to block the upper back
panel air slots behind that shelf.
This will maintain correct cool air flow among the
products.
The plate should be fitted in the location slots
immediately below the shelf brackets.
Loading
Restrictions
It is important to leave adequate free space for the refrigerated air to circulate
within the cabinet.
The air grills at the front of the cabinet must not be covered or restricted.
Defrost Cycle
Defrosting of the evaporator coil is fully automatic. Measurements of air and coil
temperatures control the commencement and duration of the defrost cycles.
This active defrost system improves the energy efficiency of the cabinet, and
minimises temperature fluctuations.

Part No. 20862 Rev. G February 2015 - 12 - Visair+ Chilled Cabinets
Routines
VISAIR+ CABINETS - OPERATION
After Hours
Ideally, cabinets should not be turned off after hours or at night.
If the cabinet is turned off, transfer the products to a cool store. When the
cabinet is turned on again, allow it to run for 30 minutes before returning the
chilled products.
Cleaning
It is recommended that cabinets be cleaned at the end of the working day, since
they need to be shut down for this. See Cleaning section.
De-frost Cycle
Defrosting of the evaporator coil is fully automatic. Measurements of air and coil
temperatures control the commencement and duration of the defrost cycles.
This active defrost system improves the energy efficiency of the cabinet, and
minimises temperature fluctuations.
If you suspect that the defrost system is not working properly, have it checked
by a qualified service person.
Operators must not attempt to adjust the refrigeration controller.
Temperature
Checks
Cabinet temperatures should be routinely checked,
to confirm satisfactory operation.
All cabinets are fitted with thermometers, to give an
indication of air temperature, but a temperature
probe should be used to check package temperatures.
To avoid misleading temperature measurements, do not take a reading if the
DEFROST indicator light is ON.

TROUBLE SHOOTING continued
Boil-off /Pump
Failure LED
illuminated
If the cabinet shuts down and the Boil-off/Pump fail LED fault light is lit, then
either the condensate pump has failed or the boil-off element thermal cut-out
will have tripped.
Thermal Cut-
out Tripped
Check if the probe in the boil-off tank is dirty and needs cleaning (a dirty probe
can complete a circuit to earth causing the unit to think water is still present and
keep the element powered up) clean if required.
Check if the probe in the boil-off tank is bent or incorrectly positioned and
touching the side of the tank - (this will complete a circuit to earth causing the
unit to think water is still present and keep the element powered up) repair as
required.
Check if the control unit is faulty and continues to give an out-put to the element
relay when no water is present. Disconnect the probe wire from terminal "S+" on
the control unit. If it continues to output 230V on terminal "L1" after 10 seconds,
replace the control unit.
Water present,
but no heating
If the boil-off element does not come on even though water is present and
touching the bottom of the sensor probe, check the following:
Check for 230V across the element, if there is 230V across the element and
the element does not heat replace the element.
If the thermal cut-out has 230V supply, try resetting the thermal cut-out. If
the thermal cut-out won't reset replace it.
If 230V is not present at the thermal cut-out, check if the element relay has
230V supply to its contacts. If no power is present at the switched terminals,
check the cabinet power supply. If 230V power is present on the switched
terminals, check if the relay coil has 230V power across the coil terminals. If
there is 230V across the element relay coil terminals, replace the relay.
If 230V power is not present across the element relay coil terminals, check
for a 230V out-put from the control unit terminal "L1". If 230V power is not
present, check for a 230V power supply into the control unit on terminal "L".
If 230V power is present on the control unit terminal "L", check the unit by
shorting out the sensor terminals "S+" & "S-". If after shorting sensor
terminals "S+" & "S-" the unit does not provides a 230V output on terminal
"L1", replace the control unit. If the control unit does provide a 230V output
on terminal L1 then the sensor wiring and sensor need to be checked.
Check the sensor wiring for continuity and repair or replace if open circuit.
Check the probe in the boil-off tank for dirt build-up over its surface (this can
act as an insulator), clean as required.

TROUBLE SHOOTING continued
Lights not
working
When a cabinet alarm condition is present, the cabinet lights will go out to alert
staff of the alarm condition.
To determine the cause of the alarm condition, check the Carel controller
display and the LED status indicator lamps.
Carel Controller
Display Alarm
Codes
Alarm code “IA” indicates the fault is due to the refrigeration high-pressure
switch or low-pressure switch, tripping open circuit.
Alarm code “dA” indicates the fault is due to the drain pan condensate pump
float switch, reaching its high water level limit.
LED status
indicator lamps
“Boil-off/Pump failure” indicator lamp lit. This indicates that the fault is due to the
drain pan condensate pump float switch, reaching its high water level limit.
“Operational problem” indicator lamp lit. This indicates that the fault is due to the
refrigeration high-pressure switch or low-pressure switch, tripping open circuit.
Fault remedies
For “IA” and “Operational problem” lamp fault indication, carry out the following:
Check for obstruction to the condenser airflow in and out of the cabinet
and rectify as required.
Check and clean the condenser coil if required.
Check the refrigeration system operating gas pressures and rectify any
faults as required.
For “dA” and “Boil-off/pump failure” lamp fault indication, carry out the following:
Check the condensate pump pick up filter is not blocked, clean as
required.
Check the operation of the condensate water pump and repair/replace
as required.
Check the operation of the boil-off element, thermal cutout and element
controller. Repair, reset or replace as required.
If no fault can be found with the above, drain the excess condensate
water from the system by disconnecting the blue plastic pipe from the
boil-off and place the end in a suitable container. Turn cabinet power on
and the pump will pump the water out of the cabinet into the container.
Turn the cabinet off and re-connect the blue pipe to the boil-off. Turn the
cabinet back on and check for correct operation. Most likely the excess
water was caused by an iced up evaporator coil. Check for likely causes
of an iced up evaporator coil.

The inside surfaces of the side panels are most easily cleaned after the
products and shelves have been removed.
Shelf Trays
The shelf trays are easily lifted off for
cleaning.
The complete shelf
module can also be
removed by lifting it
vertically, to
disengage the
support brackets
from the back panel.
Spillage Tray
If there is liquid in the spillage tray, pull the
base drawer forward, and place a
receptacle under the drain, before removing
the plug.
If spillages
contaminate the well,
pump and boil-off
unit, objectionable

VISAIR+ CABINETS -CLEANING
Cleaning the
Base Cavity
The cabinet base is mounted on runners,
and can be pulled forwards to access the
base cavity.
Sweep out, or use a vacuum cleaner, to
remove any debris.
A Wet-and-Dry vacuum cleaner should be
used, since there is likely to be some water
in the bottom.
Fan Deck
The fan deck is not fixed, and can be lifted
up, unplugged and removed for cleaning.
Condensate
Pump Intake
Filter
Lift the lid off the condensate pump intake
filter and remove any debris.
The pump control switch is operated by a
magnet, mounted on a float. Be sure to fit
the float with the magnet against the lid,
when it is
replaced.
Condensate
Capacity
Warning
The condensate pump and boil off heater is only designed to handle cooling-coil
defrosting water that drains from the well during normal operation. The boil off
container has a capacity of two litres.
When cleaning, DO NOT fill the well with liquid, or attempt to hose it out. The
condensate pump only operates when the main switch is on, so the well will not
empty until the power is switched on again.
Cleaning
Materials
Steel trays, shelves, grills etc. should be cleaned with hot soapy water then
dried off with paper towel or dry cloth.
DO NOT use abrasive pads or cleaners as these may damage surfaces.
Warning: Dishwasher detergent may damage anodised aluminium parts.

VISAIR+ CABINETS -CLEANING
Cooling Coil
and Probes
With the back plates removed, the cooling coil is
exposed. No cleaning is normally required, but if there
is any debris visible, carefully remove it with a vacuum
cleaner.
Be very careful not to bend or distort the fins of the
cooling coil, as this would
reduce the airflow.
Also be careful not to
move or disturb the
location of the two
temperature probes.

Part No. 20862 Rev. G February 2015 - 20 - Visair+ Chilled Cabinets
Mandatory Cleaning Routines
VISAIR+ CABINETS - CLEANING
Warning
It is mandatory to have the radiator fins cleaned periodically, by a
refrigeration engineer. (see Servicing section).
Failure to carry out routine cleaning/servicing schedules will void the
warranty on the refrigeration equipment.
To maintain optimum performance, cleaning must be regular and thorough.
It is recommended that a schedule of cleaning operations should be drawn up.
Condenser
Radiator
For efficient refrigeration performance, the
condenser radiator must be clean. To
access the radiator, the bottom panel must
be removed from
the back of the
cabinet, so this
would normally be
done by a service person, rather than the
operator.
Be careful not to disturb the location of the air temperature sensing probe.
Condenser
Fans and Air
Duct
The bottom side panels must be removed to
access the two condenser fans, so this
would also normally be done by a service
person.
The fan units pull out from either side of the
cabinet, and can be unplugged and taken
away for easy cleaning.
Vacuum away any dust and fluff in the duct.
Inspection and
Rectification
As part of the cleaning routine, the controls, mechanical parts and electrical
wiring should be inspected for damage, deterioration or need of adjustment.
If any small faults are found, have them attended to promptly by a competent
serviceman. Don’t wait until they cause a complete breakdown.
