7. DRAIN CONNECTION
Be sure to connect the drain hose properly.
Otherwise water leaks from the drain hose may
damage the surroundings (property).
CAUTION
1. Drain line shall be as short and straight as
possible. The drain hose shall have an
adequate pitch and fall so that no part is
higher than the drain outlet.
2. To prevent a backflow, do not connect the
drain hose directly with the sewer system.
An air gap of a minimum of 5 cm should be
between the end of the drain hose and the
water level of drainage.
3.When installing more than two units, do not
interconnect their drain hoses. If the
interconnection is necessary, provide an air
inlet per unit.

II. OPERATING INSTRUCTIONS
Fig. 12
8. Do not store bottles or cans near the air
outlet. They may freeze up and break,
causing a risk of injury.
9. Do not use combustible spray or place
volatile and flammable substances near the
unit. They could catch fire from a spark of a
switch or the like.
10. Do not put anything into the machine
compartment or the air inlet/outlet. The fan
rotating rapidly inside may cause injury or
heat.
11. Energies the for 1 hour and check for
proper temperature before putting foods in
the cabinet.
12. Do not block the air inlet/outlet with foods.
13. Do not pack the cabinet with foods. Allow
some space between them to ensure a
good air flow.
14. Do not put in warm or hot foods. Let them
cool first, or they will raise the cabinet
temperature and could deteriorate other
foods in the cabinet or overload the
refrigerator/freezer.
15. Make sure all items are snug on each shelf.
16. Moist or fresh foods and those with a strong
smell like seafood should be wrapped up
in a plastic film or packed in a container.
Otherwise the foods may dry up or give their
smells to other foods.
17.Foods containing acetic acid or yeast
should be wrapped up in a plastic film.
Otherwise they may accelerate corrosion of
the evaporator and copper tubes, resulting
in failure.
18. Foods intended for direct human
consumption should be stored on the shelf
in a proper container and protected from
direct contact with the cabinet walls.
19. Do not use the freezer to freeze foods. It is
designed only to store frozen foods. High
quality ice cream may melt during defrost
cycle and should not be stored in the
freezer.
20. The doors may become difficult to open
just after closed because of the negative
pressure created inside the cabinet. Wait for
about 30 seconds.
¬The drain hose may not be provided for some
models. If necessary, connect the optional drain
hose (1508117) to the 18 mm outer diameter drain
outlet located on the bottom rear of the unit.
