InRoom CW/DX – Operating Instructions

X Z

9.3 Raised ﬂ oor stand

9.3.1 Floor stand for 60 Hz units

The ﬂ oor stand is used to adjust the height of the cooling unit to the height of the existing raised ﬂ oor and

consists of an encircling rectangular proﬁ le of galvanized steel with adjustable screw sockets. Anti-vibration

pads are recommended between the concrete ﬂ oor and base plate.

X/Y = Opening in raised ﬂ oor

Z1 = minimal 30 mm (1.2 inch)

Z2 = minimal 800 mm (31.5 inch)

- The raised ﬂ oor cut-out should be at least 15° and

must not have any contact to the raised ﬂ oor stand,

which could result in vibration transmission.

- The dimensions of the openings in the raised

ﬂ o or (X and Y) are 10 mm (0.4 inch) longer than

the raised ﬂ oor stand. The joint must be closed by

customers with a continuous seal.

- A concrete foundation is recommended in the area

of the raised ﬂ oor supports.

- The raised ﬂ oor stand support feet should be in-

stalled on vibration dam pe ning pads (do not screw

down the supports!).

- Prior to installation of the cooling unit, the raised

ﬂ o or must be installed 7 mm (0.3 inch) higher than

the raised ﬂ oor plates, as the vibration pads are

compressed by the weight of the cooling unit.
