INSTALLATION
2.1 COOLANT CONNECTIONS
The inlet and outlet coolant connections are made at the rear panel of the chassis. Bulkhead
fittings (3/8” FNPT, double-d with 1.25” outer diameter and 1.125” across flats) are provided for
both inlet and outlet connections, which allows adaptation to specific installation plumbing using
user-installed adapter fittings.
The adapter fittings should be suitably tightened for 3/8” pipe thread. In general, the fitting
should be tightened to 2-3 turns from finger tight. The bulkhead fitting must be held stationary
(using a 1 1/8” wrench) while the adapter fitting is tightened. Suitable thread sealant, such as
Teflon tape or pipe joint compound, should be used to prevent leaks. If Teflon tape is used,
tightly wind 1 1/2 turns in a clockwise direction (when viewed looking towards the threaded end).
2.2 CHASSIS RACK MOUNTING
The chassis could be mounted with rack slides or L-brackets. Refer to the standard SG
Operating Manual, M550129-01, for rack mount assembly instructions. The chassis has seven
8-
32 PEM nuts on the sides for mounting to slides. As shipped, 5/16” SEMS screws are
installed in these locations to sealed the holes from air ingress. These screws should be
retained if the PEM nuts are not used for installation.
The slides of Ametek kit, P/N K550212-01, must be modified to be used with the SGWC
chassis. The slides must be drilled with an alternate hole pattern for three 8-32 mounting
screws, per Figure 2-1. When the slide is mounted on the right-side of the chassis (as viewed
from the front), the second screw from the rear is not used.
WARNING
To prevent the possibility of a shock hazard, the chassis
protective ground stud must be connected to the utility
service safety ground.
