3 Transport and Handling Instructions

a. Leave the CFD-50 in its protective packaging as long as possible to protect from damage

 Cutouts in the cardboard allow access to the manufacturer’s label for inspection and to the handles

for lifting without removing the packaging.

b. Transport the CFD-50 vertically when possible:

 If transport on the side is necessary, pay attention to “This side up” stickers on the packaging and

make sure package is in the correct orientation to prevent damage.

c. Keep door closed when moving the CFD-50
d. If the CFD-50 needs to be moved after initial installation, remove the water from the water tank using a

siphon hose before moving.

e. When using the handles for lifting, keep one hand towards the top of the unit to prevent tipping.
f. Avoid any excessive force to prevent damage to the CFD-50.

 Avoid any excessive force especially towards the upper and lower doors, front lower cover, and

display cover, in order to prevent damage.

 Do not lift the CFD-50 from the doors, grates, or condenser guards.

⚠ Heavy object warning. To avoid injury, use lifting aids and proper lifting

techniques when moving the CFD-50

4.1 Preparation

a. Read the instruction manual carefully.
b. Remove all packaging materials, including foam base and tape.

 Discard plastic wrappers and bags safely, to avoid suffocation of children.

c. Inventory accessories and installation tools to make sure there are no missing parts.

4.2 Positioning the CFD-50

a. Place the CFD-50 on a flat and solid ground and ensure the unit is level.
b. No pallet is required: CFD-50 has an integrated plastic base.
c. Position the CFD-50 near an accessible electrical outlet; the power cord length is 2 meters.
d. Position the CFD-50 away from direct sunlight and any source of heat (e.g. gas stove, fireplace, etc.).
e. CFD-50 must not be placed in or around flammable or corrosive gases that could cause an explosion or

electric shock.

f. In order to prevent rust or electrical leakage, the CFD-50 should not be placed in a high humidity

environment or in a location where it could be splashed with water or rain.

g. Position the CFD-50 in a well ventilated area and make sure there is a minimum of 10 cm of empty space

around the sides and back of the unit. The door latch must be accessible and the door must be able to open

freely to at least 90°.

h. Allow a minimum of 60 cm clearance above the CFD-50 for accessing the water tank lid.
