3. Connect the Three (3) 4-Port Remote Manifolds to the 5-Port On-Board Manifold as directed in Step
2.2.7, Deployment of Circulation Hoses.
4. Connect the Accessory Hose Loop 1 Female QC to one of the available 4-Port Remote Manifold
Discharge Male QCs.
5. Remove the Accessory Hose Loop 1 from the HHS3004 Reel and place at job site for thawing
application. The QCs joining Accessory Hose Loop 1 and Accessory Hose Loop 2 will be exposed
when nearing the end of Accessory Hose Loop 1.
