 Synthetic and S ilicone Oils
Oils do not require replacement or reinhibiting. However, the fluid pressure must be
adequate.
Check for the recommended pressure from section 5.2.6 of this manual.
3.1.7 Controls,
Electrical Connections
Check all conduit and wiring connections. Make sure the system is mechanically
grounded (to earth). Pay particular attention to the sensor wire connections. Make
sure no small strands of wire from adjacent terminals touch each other. Such
contact provides a direct short circuit which completely disrupts normal control
operation.
Mounting
Be sure the control and associated conduit is securely mounted.
Controls: Jumper Method
With all sensor wires disconnected and the control switch in the "automatic" position,
jumper the two terminals marked "Collector" (or "COLL," etc.) (Figure 3-17a). The
solar loop pump (and water loop pump, if used) should come on.
