Installing the LN Pump to the Tank
Ice and frost are created during normal use of the LN Pump. To prevent system failure, ensure inside of the
tank, pump, and level sensor are clean with no moisture prior to attaching the pump to the tank.
When attaching the pump to the tank, align supply and return lines centered to a handle before installation
of the clamp. Do not align the relief valves or the vent over the vacuum seal cap.
CAUTION: Incorrect alignment of the pump on the tank may cause damage to the vacuum seal cap.
To avoid risk of freezing the vacuum seal cap, Figure 26
shows the orientation of pump to tank.
