Chapter 2: Precondition
Before you install the Freezer, you need to prepare the site for installation. Examine the location where you
intend to install the Freezer. You must be certain that the area is level and of solid construction. In addition,
a dedicated source of electrical power must be located near the installation site.
Carefully read this chapter to learn:
•Storage requirements.
•Location requirements.
•Electrical power requirements.
•Space requirements.
•Service utility requirements.
•Environment Requirement.
Storage.
If the Freezer is stored for a period without power, the lid should be kept open for free circulation of air
inside the cabinet to avoid corrosion of the inner liner.
Environmental protection and disposal.
The packaging is designed to protect the appliance and its components during transportation, and it is
made of recyclable materials.
•Please return the packaging to an official collection point for recycling.
•Old appliances contain reusable materials and should not be disposed off together with household
refuse.
•Remove the spring-action hinges from the appliance, to prevent children from being entrapped in
the appliance.
•Ensure that no part of the refrigeration tubing is damaged as the refrigerant in the appliance risks
escaping to the environment.
•Information about refrigerant type and amount will be found on the Rating plate on the rear of the
appliance (Fig. 1).

Chapter 3: Getting Started
Connection to the mains.
•For safety reasons, the appliance must be earthed. If you are in any doubt, please contact an
authorized electrician.
•The appliance should be left for 1 hour before it is connected to the mains. If the appliance is
connected before that, there is a risk of damaging the compressor.
•If for any reason the appliance is disconnected from the mains, please wait 10 minutes before re-
connecting. The electronic starting device needs this time to cool down before a safe re-start can be
made.
Before use.
•Before use, the interior of the appliance should be cleaned with a mild soap solution and wiped off
with a dry clean cloth.
NOTE! Never use any kind of solvent or other chemicals.
Setting up the Freezer.
The Freezer should not be placed where it might be splashed with water, in extreme high humidity or in
direct sunlight. Any of these factors may lead to a reduction in performance and shorten the life span of the
components. The Freezer should be placed on a horizontal level and should not be placed close to a
heating appliance or heating tubes. Allow a minimum of 50 mm (2”) clearance on the sides. The back of the
Freezer should have a clearance of at least 100 mm (4”) to allow the heat from the compressor motor to
dissipate. Underneath the appliance there should be a gap of 15 mm approx. (1⁄2”). On a soft surface, e.g.
carpet, it may be necessary to ensure the correct distance by means of spacers.
Electrical supply.
The electrical supply should always be in accordance with the rating plate on the back of the Freezer.
The supply must always be in accordance with the law and regulations regarding electrical safety, if any
doubts contact your supplier.

Chapter 4: Performance Features and Safety Precautions
Refrigerant
In the BMF Freezer there are used one type of refrigerants. Carefully read the below description of the
refrigerants: R290.
Demand for information: Personnel working with these refrigerants mentioned above and below
must be educated to know about these safety sheets.
Field of application:
R290: The refrigerant is used as refrigerant for R290, is refrigerant grade propane, a natural, or "not in
kind", refrigerant suitable for use in a range of refrigeration and air conditioning applications. The use of
R290 is increasing due to its low environmental impact and excellent thermodynamic performance. It is
non-toxic with zero ODP (Ozone Depletion Potential) and very low GWP (Global Warming Potential). It is a
flammable refrigerant and therefore not suitable for retrofitting existing fluorocarbon refrigerant systems.
1. HAZARDS IDENTIFICATION:
EMERGENCY OVERVIEW: WARNING! Flammable gas. Contents under pressure. Causes damage to
the following organs: Nervous System. Vapor may cause flash fire. Keep away from heat, sparks
and flame. Do not puncture or incinerate container. Keep container closed. Use only with adequate
ventilation. Contact with rapidly expanding gases can cause frostbite.
POTENTIAL ACUTE HEALTH EFFECTS:
SKIN: No known significant effects or critical hazards.
EYES: No known significant effects or critical hazards.
INHALATION: Acts as simple asphyxiant.
INGESTION: Ingestion is not a normal route of exposure for gases.
MEDICAL CONDITIONS AGGRAVATED BY OVEREXPOSURE: Acute or chronic respiratory conditions
may be aggravated by overexposure to this gas.
2. FIRST AID MEASURES
No action shall be taken involving any personal risk or without suitable training. If fume is still suspected to
