Page 15: Plumbing Requirements
Plumbing Requirements Ensure the unit is off before connecting tubing to the unit. To prevent damage to the plumbing lines, always support the fittings while installing/removing the pumping caps and lines. Hose Connections The pump connections are located at the rear of the pump box and are labelled (pump outlet) and (pump inlet). -
Page 16: Tap Water Cooling Connections
Tap Water Cooling Coils The unit is equipped with a cooling coil located behind the stainless steel baffle in the bath, see page 5. The coil is useful for maintaining near-ambient tem- peratures, or when cooling from elevated temperatures. Temperature stability can also improve by circulating cold fluid through the coil. - Page 17 Circulating to an open container Levelling Device Outlet Inlet Bath (Rear View) Open Container A stainless steel leveling device is available to aid circulation to an open vessel. Contact our Sales Department for more information (see Preface). Support the leveling device over the open container with a ringstand. Stagger the tubes in the leveling device so one tube is submerged in the vessel fluid, and the other tube is level with the fluid surface.
