These compact units come in three models; CU-350 ECO, CU-450 ECO and
CU-900 ECO with varying capacity depending on the size of the cold room. They
are for installation in a recess in the wall of a cold room. Do not use foam insula-
tion when mounting the unit in the recess niche. The units have a ‘cold side’ – the
element which projects into the cold room and a ‘warm side’ – the element which
projects into the outside of the cold room.
They are designed for chilling food for use in private households and similar appli-
cations. The unit cannot be placed on the outside wall or against an uninsulated
garage. The correct temperature in the cold room will depend on correct con-
struction and insulation. Leave the refrigeration unit inactive after installation for
approx. 2 hours before connecting to the mains electricity. This will allow the oil
to run back into the compressor after transportation and installation. If it has been
stored in sub- zero temperatures, allow to stand for 24 hours at room temperature
before starting.
There must be an adequate distance to the ceiling over the unit on the warm side
to allow disposal of the hot air produced. The units require a power supply of 220-
240VAC 50 Hz and must be connected to an earthed min.10A mains socket. If the
power cable is not long enough (2.6m mains cable connected to warm side), call
an electrician to install an extra min.10A earthed socket. If the unit does not start
as soon as it is plugged in, it will start after a delay of up to 7 minutes. In the event
of full load or frequent door opening/closing, the compressor will run longer and
it will take longer to reach the desired room temperature. Keep the door closed as
much as possible. Ambient temperature on the warm side of the unit must always
be higher than set temperature inside the cold room, but must not exceed 38°C,
or be less than 16°C.

Pre-installation
First, unpack the cooling unit and check for any transportation damage. Do not
use a damaged cooling unit. In the event of damage, please contact the ship-
ping company and make sure that the damage is noted on the consignment note.
Check that all the items on the item list are present. Contact the manufacturer in
the event of damage or missing parts.
Check that the wall recess has the correct dimensions for your unit and that the
distance to the ceiling is correct (see dimensions and technical specifications).
Also ensure that the unit is placed as high as possible on the wall for stable tem-
perature in the cold room. Distance between walls in the cold room must be min.
1000 mm to prevent the cold air from stagnating around the unit. Do not place the
unit directly opposite the door as this can cause condensation on the magnetic
seals. Do not place the unit over a heat source.
If the power cable is not long enough, have an electrician to install a minimum
10A-earthed socket closer to the unit. Never allow the unit to be permanently con-
nected via an extension cord.

14 5. Installation Instructions
1. Attach the wide foam tape to the lower surface of the wall recess with the
adhesive side down.
2. Slide into the wall recess from the outside of the cold room until it stops against
the edge. Centre unit in the wall recess and screw securely to the wall using the
4 screws supplied. Tighten these screws until the rubber seal is pressed gently
against the wall.
3. Mount front cover using the 4 screws supplied.
4. Insert insulation between unit and wall recess from the cold room side. Ensure
that all sides of the unit are insulated! NOTE: Do not pack insulation tightly or
use foam insulation around the cooling unit.
5. Fasten D-seal to the wall around unit on the cold side before mounting interior
trims (trims are optional, and not supplied with the product). This is important
to avoid vibration transferring to the wall structure.

6.6 Cleaning and maintenance
It is important to clean the condenser dust filter at least four times a year, and the
condenser at least once a year, to ensure performance. The consumer is respon-
sible for keeping the filter and the condenser clean. This is essential to ensure that
the guarantee will apply in the event of unit malfunction.
Filter Cleaning
• Unplug the unit from the mains.
• Remove the filter by pulling it out from the slot located in the plastic cover of
the warm side.
• Vacuum or wash it thoroughly with warm water to completely remove accu-
mulated dust.
• Dry and reinstall the filter by inserting it to the front cover slot.
Condenser Cleaning
• Unplug the unit from the mains.
• Remove the condenser filter as instructed above.
• Unscrew the 4 screws on the front cover and remove it (fig 5).
• Vacuum clean or gently brush the visible condenser fins under the large steel
bracket. Be careful not to damage the thin fins. This will reduce the unit’s cool-
ing function.
• Fix the front cover with the 4 screws and insert the condenser filter.
In very dusty conditions, clean the condenser at least twice a year and check that
the unit is properly clean. This can be done by projecting a light from the under-
side up through the condenser fins using a flashlight. When looking directly down
on the fans, it should be possible
to see the light through the fins. If
the light cannot penetrate, there is
still too much dust in the unit.
To avoid mould forming, bad
smells etc. regular cleaning of the
unit is essential. We recommend
mild, warm soapy water for clean-
ing the unit and the water collector
located inside the cold room.
