Connect Piping
Install Water Piping to Heat Exchangers
Install piping using job data, piping drawings, and the procedures outlined below. A typical
piping installation is shown in
Figure 7
.
1. Offset pipe flanges to permit removal of waterbox cover for maintenance and to provide
clearance for pipe cleaning. No flanges are necessary with marine waterbox option;
however, water piping should not cross in front of the waterbox since access will be
blocked.
CAUTION
CAUTION
!
Factory-supplied insulation is not flammable but can be damaged by welding
sparks and open flame. Protect insulation with a wet canvas cover.
CAUTION
CAUTION
!
Remove chilled and condenser water temperature sensors before welding con-
necting piping to water nozzles. Refer to
Figure 2
. Replace sensors after welding
is complete.
