GENERAL INFORMATION

PMNFR MULTIDECK - HUSSMANNPAGE 
CAUTION: Gas is under high pressure.
TCO2/CO2:
The refrigerant TCO2 and CO2 is a high pressure gas
that is compatible with the environment, but is not
flammable. Pay close attention during transport,
installation, and dismantling not to damage the
refrigerant pipelines.
EVENT OF DAMAGE:
Keep surrounding flames or sources of ignition away
from the appliance and gas. Properly ventilate the
premises and use a breathing apparatus. Turn the unit
o and notify the customer service department. Fire
and heat may cause gas receptacles to rupture. Use
water spray and not jet or fog to extinguish.
R449A (Solstice® N40) is a non-flammable HFO blend
used in low and medium temperature refrigeration
applications. It provides a combination of lower Global
Warming Potential (GWP) and higher energy eiciency.
R449A has a GWP of 1273. It is non-ozone-depleting
which can be used in existing installations or for new
installations.
EVENT OF DAMAGE:
Vapours of this refrigerant are heavier than air and can
cause rapid suocation by reducing oxygen available
for breathing. Contact with liquid can cause frostbite
and severe damage to the eyes. The system including
the refrigerant is under pressure, it should be protected
from sunlight and other heat sources.

PMNFR MULTIDECK - HUSSMANN
NOTE: Check underside of case
before liing to ensure no damage to
electrical, drain box, or other extrusions
occurs.
NO OBJECTS ON CASE: Do not
place objects, stack, or use the top of
the case as storage. Object may fall
and cause injury to personnel and/or
damage to the case.
AIR FLOW:
Sources of heat or air
flow external to the
cabinet should be
avoided; i.e. ventilation
ducts, open doors, and
direct sunlight. This will
deter external air from
disrupting the air flow
from the cabinet thus
will help to maintain its
performance.
LOCATION:
The refrigeration case should be positioned in a manner
that optimal air flow can flow through the underside
and rear. This will minimise the risk of condensation on
the back and/or underside. Leave a minimum 75mm
gap between the rear of the case and the back wall.
STOCKING SHELVES:
When stocking the shelves, be sure to leave a 25mm
gap in between the stock and the above shelf to ensure
even and consistant airflow. Not doing this correctly
may result in a blockage of airflow which could freeze
the stock at the rear, and not enough refrigeration to be
produced toward the front of the case.

NOTE: These cabinets are heavy and
can have high centres-of-gravity (thus
‘tippy’). Use appropriate PPE and tools
and manpower levels.
Cases have been factory tested to ISO 23953, +25oC
at 60% RH, and cross dra of maximum 0.2m/s. For
best performance, we recommend maintaining store
temperature below +24oC at 50% RH.
To avoid condensation build-up, cases should be
positioned to allow air to freely circulate around the
underside and rear of the case (refer page 7). Cases
must be level.
Open refrigerated cases are sensitive to excessive air
disturbances. Air currents passing around cases will
seriously impair their operation. Do NOT allow air
conditioning, electric fans, open doors, or windows,
etc., to create air currents around the cases.
Place the case away from any heat sources as the heat
radiation andheatcurrentswill impairtheperformance.
The exterior of these cases provide space for air
circulation. However, if the store conditions are outside
the recommended limits, a fan ventilation kit can be
requested.
Case dimensions and case weight can be found on the
rating plate. Also refer to the latest Product Engineering
Data (PED) available from Hussmann Customer Service.
Always ensure that the moving device is of a suitable
type, and has suicient liing capacity for the case
weight and dimension. Always li cases from the
underside.
It is the responsibility of the transport company to
insure adequate loading strategies are implemented to
insure the safe transportation of the Hussmann cases.
Cases should be strapped using the indicated strapping
points highlighted on the case packaging with the “strap
here” stickers. Cases should be strapped in position
ready for transport with the appropriate rated strapping
and strap corner protector. Cases need to be secured
correctly during road transport to insure damage free
delivery. In Australia, cases should not be transported
without the strap corner protectors to insure that the tie
down web straps used from cutting into packaging and
or causing damage to case panels in transport.
The strap corner protector is a case transport
requirement in Australia, and disregarding using the
protector may cause transport damage. Warehouse
Managers may refuse loading without the necessary
implementation of correct strapping protection.
Transportation requirements are to ensure case
integrity and prevent unnecessary damage and avoid
delays in the case installation schedule.
Move the merchandiser as close as possible to its
permanent location and then remove all packaging.
Check for damage before discarding packaging.
Remove all separately packed accessories such as kits
and shelves.
