3 Installation
3.1 Overview
For site preparation follow the guidelines established in
Section 2 Site Preparation
. The information in this
section will partially copy some of the information in that section as a reminder of how important site
preparation is in the installation of the
P-K SONIC
TM
boilers with NURO controls.
3.2 Electrical Connections
3.2.1 Power Requirements (CM300-CM399-CM500)
The SC-1500 and
SC-2000
boiler requires
208-240 VAC
, single phase, 60 hertz electrical service. The total
operating amperage is indicated on the rating nameplate and the SC-1500 and SC-2000 requires less than
15 Amps at full load. Before starting the boiler, check to ensure that the proper electrical service is connected
to the boiler.
The
SC-3000
and
SC-4000
boilers can be manufactured for
208-240 VAC
, three phase, 60 hertz electrical
service
OR
440-480VAC
, three
phase, 60 hertz electrical service. The total operating amperage is indicated on
the rating nameplate and the
SC-3000
&
SC-4000
boilers require less than 20 Amps at full load. Before starting
the boiler, check to ensure that the proper electrical service is connected to the boiler.
NOTE
The SC-3000 & SC-4000
MUST
be ordered to the correct voltage!
IT IS NOT
POSSIBLE
to convert an SC-3000 or SC-4000 between the 240V and 480V
configurations in the field
.
An external electrical disconnect and overload protection (not supplied with the boiler)
are required
. Refer to
Section 6
.
1
for proper wiring and configuration of the electrical connections. The boiler electrical service must
be installed and grounded in accordance with local codes or in the absence of such requirements, in the U.S.
with National Electrical Codes, ANSI/NFPA No. 70 latest edition or, in Canada, to the current Canadian
Electrical Code, Part I, CSA C22.1 latest edition. Installed conduit must not block any of the boiler’s openings
and must allow the front door to be opened.
