Installation

General Information

(single circuit), and RAUT 400, RAUT 500, RAUT  600 (dual circuilts)
air cooled condensing units. Installation procedures should
be performed in the sequence that they appear in this manual. Do 
not destroy or remove the manual from the unit. The manual should 
should remain weather-protected with the unit until all installation 
procedures are complete.

Note:

It is not the intention of  this manual to cover all possible

variations  in  the  systems  that  may  occur  or  to  provide
comprehensive information concerning every possible contingency
that may be encountered during an installation. If  additional
information is required or if  specific problems arise that are  not
fully discussed in this manual, contact your local sales office.

Note:

 “Warnings” and “Cautions” appear at appropriate places in

this manual. Your personal safety and the proper operation of  this
machine require that you follow them carefully. The Company
assumes on liability for installations or servicing performed by
unqualified personnel.

Unit nameplate

The unit nameplate gives the full model reference. The power
supply of the unit is specified and must not vary by more that 5%
of the specified voltage.

Machine room installation requirements

Foundation

A special base or foundation is not required when the  floor is
level and of sufficient strength to support the  unit's weight.

Lifting of the unit

Four lifting lugs are provided at the base of each unit for crane
lift. Attach cable slings to each lug (refer to Figure1 ) and install
a spreader bar between the cable  to protect  the unit. Make sure
that the lifting equipment is capable of handling the weight of the
unit.(Table 1 )

Clearances

Provide sufficient clearance around the unit for performance of
service and maintenance. Caution unit operation is a  function of
the air  temperature. Any recycling of the air fed out by the fans
will increase the air intake temperature over the condense fins
and result in a high temperature out.  Make sure nothing prevents
air flow to run through the unit coils. Refer to dimensional drawing
recommended for detailed clearances, under “Dimensional Data”
section.

Special lifting and moving instruction

A specific lifting method is recommended as follows:
1. Four lifting points are built into the unit
2. Slings and spreader bar to be provided by rigger and attached
to the four lifting points.
3. Minimum rated lifting capacity (vertical) of  each sling and
spreader bar shall be no less than the tabulated unit shipping
weight.
4. Caution :The unit must be lifted with the utmost care Avoid
shock load by lifting slowly and evenly.

Lifting of the unit

Isolation and Sound Emission (option)

The most effective form of isolation is to locate the unit away from
any sound sensitive area. Structurally transmitted sound can be
reduced by using spring or rubber isolators. The isolators are
effective in reducing the low frequency sound generated by
compressors and therefore are recommended for sound sensitive
installations. An acoustical engineer should always be consulated
on critical applications. For maximum isolation effect the refrigeration
lines and electrical conduct should also be isolated. Use flexible
eletrical conduit. State and local codes on sound emissions should
always be considered. Since the environment in which a sound
source is located affects sound pressure, unit placement must be
carefully evaluated.

This manual cover the installation of the RAUT 250, RAUT  300
