4.2.1 Emptying the basin
Nova and drop-in units have a drain valve beneath the basin. Water can be emptied by
opening this valve. The uni ts are fitted with a 1 m drain hose to carry water into an emptying vessel. The emptying vessel should be placed either behind the service door inside
the unit or, if not enough spac e is availab le, the vessel should be positio ned beside the unit
for the duration of emptying.
If the unit has not been connected to the sewer system, it is extremely important to keep
the drain valve tap closed at all times except during emptying, particularly when the unit
has been installed on a water-sensitive floor surface, such as parquet.
4.2.2 Cleaning

The appliance should not be placed close to bain-maries or ovens.
5.2 Transport and storage
The appliance should be transporte d to the insta llation sit e in its tran sport packa ge. Do not
remove package until in the immediate vicinity of the installation place. The appliance
should be transported in an upright position.
The appliance is m ade of polishe d stainles s steel an d of plastic, so it can be come scratched
very easily in site condi tions . Theref ore, the appl ia nce should be de livere d to the ins talla tion site at a later stage of construc tion work. It is forbidden t o use the appliance as an i nstallation base.
The appliance should not be stored outdoors, not even in its transport package.

5.4 Installation of drop-i n units
Drop-in units are installed inside a separately built counter. The counter must be fitted
with an installation opening; for measurements, see drawings in “Technical specifications” at the end of this manual. Suffic ient spac e must be provi ded under the table top according to the installatio n drawings (see “Technical specifications”).
Drop-in units are l ifted i nto t he inst alla tion ope ning , so tha t they re st on the table top wi th
their own weight. A sufficient number of people is needed for lifting to avoid damaging
the counter or the unit.
5.4.1 All units
Materials
The counter, where drop-in units are installed, must be damp-proof. Recommended material is, for instance, laminate-coated damp-proof chipboard. Extremely important is the
choice of material for the table top.
The counter must be strong enou gh to bear the applia nce weig ht. The weight of the appliance during operation must also be considere d when designing the counter structure. The
weight is at its most when a cold basin is used, for example, as a bottle basin.
Drop-in installation
Drop-in units have a 15 mm tall collar, which remains lying on the table top. Exceptions
are a drop-in water dispenser and a drop-in soup warmer, which have different collar
heights.
1. Table to p
2. Basin
3. GN container
Because of the ins talla ti on me thod, t he table t op must be compl etely fla t, so tha t the ed ges
of drop-in units rest evenly on the table s urface. This is to ensure that dirt does not gather
between the table top and the drop-in uni t, and water doe s not enter the counter structure.
11.2.2008 Rev. 1.1
Installation
10
The drop-in unit is mo unted on the table top with its own weight, and no separate ins ulation is req uired. If des ired, the jun ction of t he drop -in uni t and table to p can be s eale d with
silicone.
If you want to have the collar of the drop-in unit flush with the table top, you can make a
recess for the collar in the table top. In this case you should make sure that the table top
thickness is grea ter tha n the co lla r height (15 mm) and tha t the t able t op materia l i s strong
enough.
Space needed for installing the drop-in units should be taken into account: there must be
enough free spa ce a bove t he drop- in open ing for inst allat ion. Upper parts, e ventua lly constructed separately, should be installed after the drop-in units are in place.
Connections
When constructing the counter, an opening for the connection cable must be considered.
The opening must be at least the size of a plug (diameter min. 40 mm). In addition, the
edges of the opening must be finished to make sure that the connection cable is not damaged by rubbing against the opening edge.
The length of the connection cable supplied with drop-in units is 3,2 m. When building
the counter, it is advisable to design a special place for the extra leng th of the connection
cable in the counter structure.
If drop-in units fitted water connections are installed in the counter, openings for these
must also be taken into account.
Service door
The operating s w itches of drop-in units are fixed to the uni ts as standa rd. To facilitate the
use of the switches, the counter must be fitted with a service door. The minimum measurements of the service door are shown on the drawings at the end of this manual (see
“Technical specifications”).
Drain
It is recommended to carry drain water via the drain valve into the sewer system. This
means that, while erecting the counter, sewer pipe openings must be considered. If drain
connection is not possible, water is emptied through the service door.
Drop-in units are equip ped with a drai n valve be neath the basin. Water ca n be emptie d by
opening this valve. Drop-in units are fitted with a 1 m drain hose to carry water into an
emptying vessel. The emptyi ng vessel should be place d eithe r behin d the service door inside the counter or, if not enough space is available, the vessel is positioned beside the
counter for the duration of empty ing.
If the unit is not c onnect ed to t he sewer sy stem, it is extre mely import ant to ke ep the drain
valve tap closed at all times except during emptying, particularly when the unit has been
installed on a water-sensitive floor surface, such as parquet.

5.4.2 Cold units D-I CB and D-I FrP
Condenser air circulation
Air for the conde nser must enter from out side th e count er. T he panel in f ront of t he refri geration unit must be fitted with a grid or perforation to ensure fresh air inlet for the condenser. The grid must be larger in size than the condenser area, i.e. > 0,09 m2. At least
50% of this area must be perforated. It is advisable to attach the grid to the door used as a
service hatch.
The best way to provide fresh air inlet for the condenser is to convey air to the condenser
with the help of a collar placed between t h e machiner y an d the gri d .
Condenser air ci rculation ca n be improved furt her by le aving the counter’s lowe r structur e
open and/or by ensuring flow-through for the counter. Flow-through can be provided by
fitting a similar grid as describe d above on the other s ide of the refrigera tion unit, opposite
the grid located in fr ont of the condenser.
Condenser air circulation
Disregard of condenser a ir circ ulati on weaken s the operat ion of the cold unit . Insuf fic ient
air circulation can cons iderably reduce the drop-in unit’s performance, particularly if the
disregard leads to internal air circulation, that is if air blown out of the condenser is sucked
back into the condenser.
Insufficient air circulation burdens the refrigeration machinery and shortens the service
life of the compone nts. Energy consu mpt ion is also greater for drop-in un its, if their c ondenser air circulati on has not been properly taken care of.
Failure to provide sufficient air circulation for the condenser invalidates the warranty of
the refrigeration machinery.

5.5 Installation of Nova unit s
If the un it is fitted with w h eels, it must be in stalled on a level s u r f ace. When the unit is in
its correct place, the wheels must be locked to point away from the centre of the unit. If
the unit is fitted with legs, these can be adjusted so that the unit stands steadily on an uneven sur face as well.
If a serving line is composed of several units, they can be linked together from under the
tray slides with the help of grey Nova connectors delivered with the unit.
5.6 Electrical connections
Connect the appliance to the power supply with an earthed socket. For making the connection, a socket prote cted with a fuse of max. 16 A has to be provided for each unit.
5.7 Start-up
5.7.1 Cold basin and frost plane
