Service Air Piping - Sullair 3000P User Manual

SECTION 4
NOTE
Variable speed drive compressors are
NEMA 12 rated and must not be installed
outside or exposed to the elements.
The compressor should be on a concrete pad, which
is designed to drain water away from it. If the
concrete pad is sloped, then the compressor must be
mounted so that it is level. The base or skid must be
fully supported where it contacts the concrete pad.
A weatherhood option should be selected to prevent
direct rain and snow from falling on the unit. If local
weather conditions can be extreme such that direct
rain or snow may fall on the unit, it should be in a fully
enclosed room or building.
If installed under a shelter, air-cooled machines must
be positioned in a way that prevents air recirculation
(i.e., hot exhaust being allowed back to the system
air inlet).
In installations that
compressor, hot air exhaust should not be directed
toward the fresh air intake of the second unit or an air
dryer.

Figure 4-1: Service Air Piping, Typical Installation
A standard machine installed outside must not be
started or run if the ambient temperature in and
around the compressor drops or may drop below
35°F (1.7°C).
Compressors with integral dryers can be
damaged by ambient temperatures below
freezing. The dryer electrical system is
Nema 12 rated and should not be installed
outdoors or in an unheated space, subject
to freezing temperatures.
For installation in a below freezing climate, a low
ambient option with heat tracing and a separator/
sump tank heater must be installed.

SERVICE AIR PIPING

Review carefully the total air system before installing
a new compressor. Items to consider for the total air
system include liquid carryover, pipe sizing, and the
use of an auxiliary receiver tank. The installation of a
one
drip leg or multiple drip legs, installation of a line
filter(s) and the installation of isolation valve or
valves. These considerations are important to ensure
a safe and effective system. See Figure 4-1.
