temperature. Below 50°F (10°C) some fl uids become very thick. Fluid should be
in a pumpable liquid form prior to fi lling the system. Refer to the thermal fl uid
manufacturer’s recommendations.
Adhere to the following when fi lling the system:
1. Refer to Figure 11 for the drain and fi ll connection.
