WHAT YOU NEED TO KNOW ABOUT YOUR NEW GRAM PRODUCT
Thank you for choosing a Gram product
This manual is divided into two major sections, a compulsory and a complementary
section.
The compulsory section deals with details that you must know of in order to use
the product. The complementary section gives advice about utilising our many
extended functions. It should be stressed that no cabinet is completely
maintenance-free, however the most typical issues can be prevented with correct
use and maintenance.
Easy to operate, total control
The Gram KPS cabinets are blast chillers and freezers that fulfi ll all HACCP
requirements for a cook-chill kitchen. The entire range of KPS cabinets utilise the
same controller with short cut keys to make it easy to run your desired cycle. You
can also customise your own blast chill or blast freeze programmes to enhance
operational fl exibility.
If you do experience operational diffi culties a diagnostic error code will be shown on
the display. The cause and remedy will be described within this manual.
All KPS cabinets utilise HFC-free insulation.
Support
If you do not fi nd the information you
need in this manual, our service department
is ready to help you. Often issues can be
readily solved over the telephone.
Contact information for the
service department: – see backpage.

Getting started
The following models are comprised
in this manual:
KPS 20, 40, 60, 90, 120 and 180.
The models in this manual are all
termed as “cabinets” although KPS
120 and 180 are rooms that you can
walk into.
Some functions or properties can
deviate from cabinet to cabinet.
Differences will be mentioned.
General use of the cabinet.
The KPS cabinet is not a storage
cabinet. Therefore the cabinet does
not defrost automatically. Use the
appropriate short cut key to run
a defrosting cycle, see paragraph
“Short cut keys” or the Quick Guide.
After end of the blast chill or freezing
cycle the system will automatically
switch to the storage mode (+2°C
at the end of the positive blast chill
phase and -22°C at the end of the
freezing phase). When the cabinet
runs a storage cycle the display
shows “cons”.
To achieve an effective cooling cycle it
is advisable to run a pre-cooling cycle
prior to selecting any blast chill or
freeze cycle.
It is important to insert the probe
correctly. When running an IFR cycle
the probe is inserted until the “disc”
of the probe reaches the surface of
the foodstuff. Concerning other cycles
using the probe the needle is inserted
until the point reaches the center of
the foodstuff. See fi gure 1.

cabinet.
The complementary part deals
with extra functions, including use
of recommended programmes
and storage and use of user’s
programmes.
In addition the manual has a Quick
Guide which offers an overview of the
most common functions and how to
use them.
Use of display images.
This manual will refer to display text
using images as in the example

Correct installation of the cabinet
before usage.
To ensure reliable operation make
sure the following is observed:
The cabinet must be located in a dry
and ventilated room.
The cabinet is designed to operate in
ambient temperatures of up to +30°C.
Avoid location in direct sunlight or
near any heat sources, i.e. an oven.
The cabinet can be placed directly
against a wall. However, the KPS
20 and 40 must be located with a
distance of minimum 100 mm to the
wall behind the cabinet and at least
50 mm space above the cabinet is
required.
For versions with legs, use the screws
on the legs to make sure that the
cabinet stands level and upright.
Before usage, clean the cabinet
with a mild soapy solution and dry
thoroughly.
If the cabinet has been transported
in horizontal position it must stand
upright at least 2 hours before it
is started to allow the oil from the
compressor to run back.
This only concerns the KPS 20 and
40 as well as KPS 60 cabinets with
built-in compressors.
Installation and preparation
Installation continued.
The cabinet must not be located in a chloride/
acid-containing environment (swimming-bath
etc.) due to risk of corrosion.
The KPS 20, 40 and 90 are delivered with height
adjustable legs and with doors with removable
sealing strips. The KPS 40 is also delivered with
reversible door.

Read the text below thoroughly before
electrical connection.
The KPS 40, 60, 90, 120 and 180
must be connected by an authorized
electrician.
The KPS 20 can be connected by the
user himself.
When the cabinet has been connected,
press to turn on the cabinet.
If there is a power failure the controller
will remember the settings. When
the power returns the cabinet will
continue in the programme settings
prior to the power failure.
Connecting the cabinet - continued.
Do not use the cabinet before all shieldings
have been mounted to prevent access to live or
rotating machine parts.
Do not use the cabinet, if the wire has been
damaged. In this case the cabinet must be
examined by a service electrician from Gram
Commercial or an authorised refrigeration
company with knowledge of Gram’s products.
The cabinet must not be used outdoor. All
earthing requirements stipulated by the local
electricity authorities must be observed. The
cabinet plug and wall socket should then
give correct earthing. If necessary, contact an
electrician.
!
COMPULSORY PART
As regards the KPS 60, 90, 120 and 180 defrost
water must be led to an external drain.
See page 11.
The KPS 20 and 40 are equipped with a water
tray which at point of delivery is placed inside the
cabinet. The user must place the tray under the
cabinet when the cabinet is installed. The tray
must be emptied when needed. Alternatively,
these cabinets can be connected to an external
drain.
