3. Your Dulas Mains Powered Refrigerator.
Congratulations on choosing the Dulas VC225ILR vaccine refrigerator. With over 30 years of
engineering experience in the production of vaccine refrigerators, Dulas is considered one of the
market leaders in this field.
The VC225ILR is Dulas’ latest innovation in vaccine refrigeration. Using technology adapted from
our ground breaking Solar Direct Drive refrigerators we have created a mains powered refrigerator
that is ideally designed for intermittent electricity supplies. With advanced insulation and a robust
phase change lining, our ILR delivers an exceptionally long holdover while also providing 100%
freeze free protection for your vaccines. This new technology offers the same renowned Dulas
quality and reliability that have always kept your vaccines safe, but in a simpler and more efficient
package.
How does the Dulas ILR work?
When mains power is available the refrigerator runs, cooling the vaccine compartment and its
contents. In many situations electricity is intermittent, causing problems for traditional mains
powered refrigerators. To maintain the temperature when the power is off the Dulas ILR has a
phase change lining. This lining acts as a “cold store” and stores energy that keeps the
temperature inside the refrigerator stable when electricity is not available. The temperature of the
cold store in the Dulas ILR is naturally between +4 to +5°C which is the perfect temperature
required for safe vaccine storage and means that the product is 100% Freeze Free.
In order to store sufficient energy to deliver the specified holdovers, the refrigerator must
be allowed time to charge its cold store. Refer to the table below to see how long it will take
for the Dulas ILR to be ready to store vaccines:

Recommended power supply
The Dulas ILR must be connected to the supplied Dulas AC power supply (PS-ILR-001). This
power supply delivers the DC electricity required by the refrigerator. Connect the PS-ILR-001
power supply to an AC input of:
Nominal 230V 50Hz single phase supply rated to at least 5A. (110V and or 60Hz models
available)

5. Material Safety Information
THE REFRIGERATOR
The Dulas VC2225ILR conforms to the European directive 2002/95/EC on hazardous substances
and does not contain the following elements: lead, cadmium, mercury, hexavalent chrome, PBB or
PBDE.
The absence of ozone destroying materials is in accordance with EC 1005/2009 (CFC-free)
It is compliant with European Standards (CE) EN60335-1:2010 & EN60335-2-24:2010.
R600a refrigerant –Isobutane, is highly flammable when mixed with air. Do not inhale, ingest, and
avoid contact to skin. Ensure that any work carried out on the refrigeration circuit is done by a
competent refrigeration engineer.
THE PHASE CHANGE MATERIAL (PCM)
The refrigerator contains an organic phase change material (PCM) that provides the energy store
for the refrigerator. This PCM material is a paraffin wax that is liquid at room temperature and is
stored in large tanks secured inside the walls of the refrigerator. In normal use the user will never
be aware of its presence. This PCM is classified under regulation (EC) No 1272/2008 as a
category 1 aspiration hazard and is classified under regulation 67/548/EWG, 1999/45/EG as
having the potential to cause physical harm (R65 & R66). At normal ambient temperatures this
product will be unlikely to present an inhalation hazard because of its low volatility. At high
temperature aerosol/mist can cause an irritation of the respiratory tract.
H304 May be fatal if swallowed and enters airways.
P301 + P310 IF SWALLOWED: Immediately call a POISON CENTRE or
physician.
P331 DO NOT induce vomiting.
R65: Harmful: may cause lung damage if swallowed.
R65: Repeated exposure may cause skin dryness or cracking.
In the event of a PCM spillage:
Wear suitable protective clothing, gloves and safety glasses when clearing up spillages.
Use an absorbent substance such as sand to contain any escaping material.
If the PCM contaminates rivers and lakes or sewers inform authorities. Avoid water ingress
underground. Do not flush into surface water or sanitary sewer system.

8. Refrigerator Loading
IN ORDER TO KEEP INTERNAL TEMPERATURES STABLE AND MINIMISE ENERGY CONSUMPTION,
ONLY OPEN THE LID WHEN STRICTLY NECESSARY.
The VC225ILR refrigerator has a single compartment specifically for the storage of vaccines, see
Section 4. This compartment is designed to maintain a stable temperature between +2°C and
+8°C across an ambient temperature range from +5°C to +43°C. There are no points within the
vaccine compartment that drop below freezing and thus no danger of freezing vaccines.
Optional stacking baskets are available. These are designed to make stock management easier
and encourage air circulation within the compartment.
Try to keep the lid open for as short a time as possible.
Stock management
Allocate a certain space for each different type of vaccine, so that they may be located rapidly.
Check the vaccine labels and adhere to any special requirements.
Always use before the expiry date (store older vaccines on top).
Store the most frequently used vaccines in the top baskets for easy access.
WARNING: ALWAYS FOLLOW THESE VACCINE STORAGE GUIDELINES

9. Status Light
The green LED light on the front of the refrigerator illuminates to indicate that the compressor is
operating. The compressor will run if the refrigerator temperature is above about 4 degrees and
there is sufficient solar power.
Normal operation
The refrigerator warms up slightly overnight. It is usual for the compressor to start running shortly
after sunrise. It will run continuously for a few hours to cool the refrigerator. After this time the
compressor will begin cycling on and off to maintain the correct internal temperature. This will
continue until the sun sets at the end of the day. At night there is no power to the refrigerator and
so the compressor will not run nor will the LED light operate.
