ZShooter Glycol Harnesses & Connections

Scope: supply/return circuits, manifolds, cooling loads, and module disconnects. Related operations: environmental services.

Diagrams: hardware composition and glycol view.

Assembly boundaries

• ZFront manifold with temperature, flow, leak monitoring, and shutoff

• ZImager submanifold

• ZSpec VIS submanifold

• ZSpec NIR submanifold

• Mechanical-room compressor cooling

Supply and return connections

From	To	Detail
RNAS facility supply/return	ZFront manifold	Facility interface, isolation, and sensing
ZFront manifold	ZFront EBox heat exchanger	Local cooling branch
ZFront manifold	ZImager submanifold	Removable-module connection
ZImager submanifold	U/V/Z detectors and EBox heat exchanger	Branch layout open
ZFront manifold	ZSpec distribution	Removable-module connection
VIS distribution	EBox heat exchanger, B/G/R Archons and cryocoolers	Branch layout open; slit-viewer cooling conditional
NIR distribution	EBox heat exchanger, YJ/H/K Archons, external CRED2	Branch layout open
Mechanical-room facility cooling	NIR compressor	Separate facility circuit

The vacuum pump also has a cooling connection; its supply/return route is unassigned. Any NIR coldhead glycol connection remains to be confirmed with the cryogenic design.

Manifold and hose details

Manifold ports, supply/return fittings, hose assemblies, and isolation points will be added with the circuit drawings. Electrical connections for the ZFront manifold are in the ZFront harness.

Leak monitoring must remain available when ZImager or ZSpec is disconnected. Each removable branch needs isolation and caps while the other circuits remain in use.

Team notes: Branch layout, flow allocation, service fluid, fittings, and shutoff coverage remain open. The disconnected-module arrangement is part of the manifold design.
