Chapter 1 - Product Information

1.1. About HP Series Laboratory Refrigerator and Freezer

The refrigerated cabinet covered by this manual produces cold by means of low-pressure vaporization
of a liquid refrigerant, such as HCFC, HFC or HC, inside a heat exchanger (evaporator). The vapor thus
obtained is brought back to the liquid state by means of a higher-pressure mechanical compression
(via a compressor) followed by cooling in another heat exchanger (condenser). The correct, uniform
distribution of air inside the cabinet is guaranteed by one or more fan motors, depending on the
model.

The machine is composed of a modular monocoque coated with different materials and insulated with
polyurethane foam at a density of 43 kg/m³.

The instrumentation is grouped on the front panel. On some models, the motor compartment, where
the condenser unit and electrical wiring can be housed, closes automatically.

Inside, the machine is equipped with brackets suitable for supporting wire shelves, extractible drawers
and steel baskets.

The doors on all machines are equipped with a closing device with automatic return and door lock and
easily replaceable magnetic seals for perfect tightness. Measures were taken during design and
construction to obtain a machine that meets specific safety requirements, such as condensate liquid
drainage, no rough surfaces, fixed guards on moving or potentially dangerous parts, and so on.

The maximum capacity of shelves and drawers load on all HP Series models is 30 kg with weight
uniformly distributed.
All models are for indoor use and cannot be installed outdoors.
Warranty will immediately expire, if equipment is installed improperly.

1.2. Intended Use

All the listed models are suitable for storage. For this reason, we suggest only storing products that
have already been refrigerated or frozen (depending on the model).

We declare that any use outside of those allowed by the machine is considered as “improper use”
and therefore the manufacturer declines all responsibility.

Laboratory and pharmaceutical devices are suitable for:

- Storage of correctly packaged drugs, vaccines, and reagents that are not liquids or body
tissues intended for administration or introduction into the body
- Storage of other substances or materials for general use in a non-flammable or non-
explosive hospital, laboratory or pharmaceutical environment
- They are NOT to be used for the storage of blood, fluids or body tissues.

Chapter 2 - Installation
2.1. Transport and Handling

The machine must be transported and handled solely in a vertical position and following the
instructions printed on the packaging. This precaution is necessary to avoid contamination of the
compressor with oil which may cause the rupture of valves, of the cooling coils and problems with
electric motor starting.

The accessories supplied with the machine (slides, wire shelves, drawers, baskets, etc.) are shipped
inside the unit. The machine is fixed on a wooden pallet by means of screws, wrapped with
polyethylene and packaged in cardboard, sa wooden crate or wooden case. Additionally, the storage
and shipment temperature for the machine ranges from -10° to +50°C.

The machine must be handled using a forklift or pallet truck with suitable forks (fork length at least
equal to 2/3 length of the unit).
If the machine needs to be set down in order to bring it into the installation location, it is
absolutely necessary to wait at least 6 hours before switching it on. The manufacturer declines
any responsibility for problems due to transport carried out in any condition different from those
specified above.

2.2. Positioning

Incorrect positioning can cause damage to the machine and create dangerous conditions for users;
therefore, the installer must comply with the following general rules:

- Position the machine keeping a minimum distance of 10 cm from all walls. If the machine is
embedded in any type of furniture, a correct air flow of the condensing unit (compressor/fan
motors) must be always ensured. The warranty will immediately expire, if this is not
guaranteed. (Figure 1 – equipment position)

Figure 1- Equipment Position

Laboratory Refrigerator and Freezer

- Set the machine in a sufficiently ventilated environment.

- Place the machine far from heat sources and far from sources of
electromagnetic interferences (such as motors, generators,
infrared beams, telephones) which can have negative effects on
equipment functioning.
- Avoid exposure to direct sunlight and air conditioning flows.
- Remove the supplied accessories and the wooden pallet base.
- Position the machine with the aid of a spirit level. If necessary,
adjust the levelling feet on the metal base (on models fitted with
adjustable feet) (Figure 2 – adjusting feet). Figure 2- Adjusting Feet

For models taller than 1.5m installation with wall fixing brackets is recommended.

2.3. Cleaning

The Equipment is shipped already cleaned. However, it is advised to carry out a further washing
following the instructions below:

- Remove the protective PVC film from the external surfaces of the machine.
- Clean the inside of the chamber with a cloth dampened with alcohol in
order to eliminate the protective oil.

signaling.

3.3. Temperature Data Back-up from SD Card

We suggest saving every two months in the computer the SD card registered data in order to prevent
data loss in case SD CARD is lost or damaged. To make the backup of data, extract the SD CARD and
make a copy of the Backup folder in your PC, without deleting any folder nor file.

The Software CAPTURE 5.2, available in the SD card, will allow reading, creating and printing
daily/weekly graphs of the backup data saved in the USB. While the SD card is extracted, all data will
be registered in anyway.
In case of problems with SD card, always check that the lever on the side
of the same is positioned in “writing” position. If not, the controller won’t
recognize it.

In order to guarantee the maximum efficiency of the system we advise to

replace the SD card every 3-4 years.

using a ladder.

PHASE 2
Use a vacuum cleaner, air jet, or a long bristle brush to remove any dust on the condenser fins.

PHASE 3
Restore the electrical current and switch back on the device.

4.4. Condensate Water Draining

Defrosting causes the formation of condensate water. The water evaporates

automatically in models with motor compartment in lower position. In some
other models, water is collected in a tray, included in supply, which is set under
the unit and inserted in the corresponding slides. This tray must be emptied
frequently.

Optionally, models with upper motor compartment can have a collecting tray
included for automatic condensation water evaporation.

4.5. Replacing Buffer Batteries

To ensure maximum efficiency, we suggest periodically changing

backup batteries at least every 2 years. This operation can be
performed by users, easily accessing the housing located:

- At the rear of the device

- At the upper of the device (models with upper motor
compartment) Figure 36 - Battery Position
