For transport of the unit with or without pallet the following minimum measures have to be observed:With pallet width height20x1/1GN 37 1/8" 78 3/8"20x2/1GN 45 3/8" 78 3/8"Without pallet width height20x1/1GN 35 3/4" 72 1/2"20x2/1GN 44 1/8" 72 1/2" pic. 1

Attention: The unit may only be moved / transported when it is switched off and all supply lines are disconnected. When moving the unit take the trolley out of the cooking cabinet.

For pulling the unit out of the site, in case there is not enough space at the left or right side:- Cool down the unit below 100°F- Open cabinet door- Pull at the interior cabinet. pic. 2

AttentionWhen pulling the unit out of the site the door can close accidentally. Crushing hazard! For transport of the unit:a) Empty steam generator. Procedure see

operator manual. b) Disconnect water supply, drain and

additionally on gas units the gas supply line at the connection points of the unit.

c) Only exception is the power cord installed in electric and gas units. The units can be connected with plug. In this case, for transport, the power cord must be protected against damage by hooking it up in the holding device at

- The unit is delivered on a special trans-port pallet. This pallet can be used sev-eral times. Therefore don't dispose the

pallet. pic. 1

Attention: To avoid injuries make sure that always two persons are available for taking the unit off of the pallet. Crushing hazard!

For rolling the unit off the pallet, proceed as follows:a) There are rails stored on the pallet

underneath the unit. Fix these rails to the right side of the pallet using the enclosed screws (screw driver 13 mm)

pic. 2b) Remove the retaining bracket at the left

and right side of the base frame of the unit by loosing the corresponding

screws (screw driver 19 mm). pic. 3 c) Stick the handle, which is enclosed in

the scope of delivery (handle of the trolley) into the holes of the right base frame. Take trolley out of the cooking cabinet and roll the unit down from

the pallet. pic. 4d When using the pallet again for trans- When using the pallet again for trans-

portation fix the unit to the pallet using the retaining brackets and the corre-sponding screws.

For moving the unit the handle of the trol-ley can be used. Stick the handle either in the right or the left openings of the base frame. pic. 55

Mobile floor models 20x1/1GN and 20x2/1GN- Minimum space of 50 mm (2") at the

left, right and rear side of the unit must be maintained. For connecting power, gas and water we recommend a space of 500 mm (20") at the left side of the unit. At sites where not enough space is available make sure, that all supply lines are long enough for moving the unit that far forward that the supply lines can be

connected and disconnected. pic. 1

Attention: External Heat Source Proximity: Each Combi-Steamer must be clear of all external sources of heat · Increased appli-ance temperature may cause damage to unit components · Installations must comply with all local electrical, plumbing and ventilation codes · RATIONAL rec-ommends water treatment based on the results of water testing · Consult owners manual for additional installation require-ments.

- The floor at the site must be level. A height adjustment of the unit is not pos-sible.

- The unit must be secured at the site by pressing the brakes of the casters. pic. 2- Additionally the unit is equipped with fixing plates pic 3

These plates can either be glued to the floor with a special adhesive or with screws and dowels. Screws and dowels are not included in the scope of delivery. Run the unit onto these plates. Secure the unit with the slider and fasten the slider with the nuts.

- Trolley must stand level inside the unit. Attention: Observe height of the drain.

Attention:An incorrect levelled trolley can cause malfunction during operating the unit (e. g. during Cleanjet)

against slipping by a chain or cable in order to prevent damage to the electric-ity or gas supply line. Therefore a hole is in the left frame at the rear side for

connecting the chain or cable. pic. 1/2

1. Electric connectionObserve your local regulations!Basic hints and colour coding of the wires see pages 14 and 15.Electric units:• Each appliance requires an independent

fused power supply line• The units 20x1/1 GN and 20x2/1 GN

aredelivered without power cord and without plug.

• The connection terminals are located in the electric compartment. To get access open left side panel (remove the two

brackets) pic. 3Gas units:• We recommend an independent fused

power supply line for each unit.• The units are delivered with a power

cord approx 8 ft long without plug.• To get access to the terminals open left

side panel (remove the two brackets). pic. 32. For drain connection we suggest to

have a floor drain at the rear left side of the unit. In this case a drain pipe with elbow piece can be connected to the unit. The pipe should have a clear out-flow (air gap) of 1” above the floor
