AMBIENT OPERATING CONDITIONS
All “V” series Refrigerated Display Cabinets have been designed to operate
under the following conditions:
Class 3M1 Ambient temperature 25ºC
Relative humidity 60%
Max cross draft 0.2 m/sec
Product Temperature -1˚C to +5˚C
Class 3M0 (VVS727E Cabinet – with shelf in angled position only)
Ambient temperature 25ºC
Relative humidity 60%
Max cross draft 0.2 m/sec
Product Temperature -1˚C to +4˚C
Ambient conditions greater than those stated may result in poorer performance
of the cabinet and higher running costs.
LOCATION CONDITIONS
Cabinets should be sited so that external influences are minimized. Situations
to avoid are:
•
Air draughts from: Air conditioning,
Ventilation,
Heating outlets,
Entranceways,
•
Heat sources: Sunlight,
Spotlights,
Hot cabinets,
Concentrated external
lighting,
Non-insulated roofs and
walls,
•
Mechanical damage:
Shopping trolleys,
Forklift trucks,
Pallet jacks,
Floor polishers,
Extra protection may be required to minimize damage.
Any of these situations could prevent this cabinet from performing correctly.
NOTE: Unless specified, there should be a 100mm gap between the cabinet and
a wall. This is to allow sufficient airflow to prevent condensation

KEY OPERATION POINTS
•
Always keep rear doors closed when not using the cabinet
•
Do not overload the cabinet with product (see loading limits pp 13~16)
•
Do not block air delivery or air return vents
•
Do not add display ice to VLL726E and VSS726E cabinets. This will cause
fan motor damage. VLL727E cabinets are designed for display ice.
•
Do not use mechanical devices or other means to accelerate the defrosting
process, other than those recommended by the manufacturer.
•
Do not use electrical appliances inside the food storage compartmentsof the
appliance, unless they are of the type recommendedby the manufacturer.
•
Always clean cabinet as described in the cleaning section of this manual and
on the cleaning instruction label on the cabinet.
•
However, if a liquid spill should occur, the spill should be cleaned as
soon as practicable. Liquids can be acetic, and if left will risk damage
to some components in the cabinet.
RECEIVING CABINETS
Cabinets will always be dispatched in good condition. Always inspect the cabinet
and packaged accessories for damage. Note any damage on the carrier’s
consignment note prior to signing.
For concealed damage that is found later, notify McAlpine Hussmann in the relevant
country within 3 working days. Any issues will be addressed and rectified as
applicable.

NOTE: A photographic record of any damage found is required.
Also quote cabinet serial number and a brief description of the damage.
A check should also be made to ensure:
•
That all loose parts listed on the outside packaging are present and
undamaged,
•
That glass has not moved during shipment. Test any lifting glass carefully to
ensure there is no rubbing or knocking of glass that may cause future
damage. There are glass adjustment instructions in this manual
NOTE: Any shortages will follow the same procedure as concealed damage.

CABINET INSTALLATION
JOINING CABINETS
Cabinets shall be installed level front to back and side to side to allow correct
operation of lifting glass, and allow condensate to drain freely.
There is a 150 psig Dry Nitrogen (+/- 10psig) holding charge in the evaporator
coil, please check the pressure before safely releasing the holding charge. If
Dry Nitrogen holding charge is found to be below 140 psig, please undertake
additional leak checks of the evaporator coil.
1. Always identify the highest point on the floor where the cabinets are to be
installed. Cabinets will need to be levelled from this point.
2. Mark a line on the floor that shows the position of the rear skid rail for the line-
up.
3. Position the first cabinet, level end to end and front to back. Ensure the
footbolts are adjusted (50mm nominal adjustment range) to accommodate the
highest point in the floor. All footbolts must be adjusted to the floor. This will
ensure hinged glass maintains its position over time as the cabinet settles.
4. Apply a non-hardening, flexible sealant to the end of the cabinet to ensure a
seal between the refrigerated area of the cabinet and the ambient
environment.
5. It is advisable to apply masking tape to any visible joints to be sealed later,
before butting up the adjacent cabinet.
6. Place the next cabinet as close as possible to first cabinet and set the height of
the second cabinet to roughly match the first following the procedures in steps
3, 4, and 5.
7. Push the cases together and insert joining bolts. Make any minor adjustments
to exactly align the two cabinets and tighten the joining bolts.
8. Check cabinet is level from end to end and front to back at both ends.
9. Repeat procedures until all cabinets are aligned.
10.Apply finishing sealants and any jointer items. Remove masking tape from
sealed joins. Tidying up any excess sealant.
11.Fit bumper assemblies. Detailed instructions are on the following page.
12.Check all glass gaps on lift front cabinets. Adjust as required to have a 3mm
gap between each glass. A larger gap can be closed using a wiper strip
adjacent to ends on box cabinets.
13.Fit wiper strips to the ends of box cabinets where required to close any glass
gaps. Use RTV to glue to glass
14.After all services have been installed and completed, fit coving angles and
dress panels.
15.Clean the condensate deck of any filings and rubbish that may have
accumulated during installation. These may block drains or cause rust damage
to panels over time.
16.Fit any internal panels that have been removed for installation.
17.Fit all supplied accessories. A list of separately wrapped loose items should be
on the cabinet
NOTE: The front glass may be packed loose in VSS726E and VVS727E cabinets.
NOTE: There are joining diagrams at the back of this manual.

BASE OPTIONS
These cabinets are supplied as standard with removable base extensions. This allows
the cabinet to be sited on a plinth and stillmaintain the optimum access and working
height for the cabinet. A full set ofpanels should besupplied with each cabinet to make
this change. If theyare not included, contact McAlpine Hussmann for the required panels
and instructions.
KITS
There are also various kits to change cabinet configurations. Instructions for the fitting of
these will be supplied with each kit. Contact Hussmann for kit options and instructions.
ATTACHING THE FRONT BUMPER
IMPORTANT!
Bumper assembly securing screws must be fitted to all
bumper assemblies.
Bumper assemblies are sent unattached for transport reasons. Therefore,
securing them correctly to prevent dislodgement and possible injury is very
important.
The following instructions should be followed carefully.
1. Unwrap the bumper assembly. You should find a pre-assembled bumper
assembly and a number of securing screws to match the number of pre-drilled
white plastic clips on the front of the cabinet.

2. Before fitting the upper colour panel (painted panel that sits at 45°), fit the
bumper assembly.
3. Align the bottom groove in the aluminium extrusion with the bottom tag on the
plastic clips.
4. Push the top of the bumper assembly on to the plastic clips.

NOTE: If some bottom tags on the plastic clips do not sit in the extrusion
correctly they can be pushed into place once the assembly has been fitted.
This can be done using your fingers from below the assembly.
5. Pre-drill the bumper assembly aluminium extrusion at every white plastic bumper
clip with a 4.5mm drill bit, taking care not to drill through the front bumper rubber
(see insert picture for drilling depth)

•
Cross head screwdriver (Philips) PH2
•
Square drive screw driver S2
•
Star drive keys
•
