(IM-P018-02) supplied with the product.

The trap should be installed with the inlet below the equipment being

drained. The outlet should always be above the trap.

Adjustment

The position of the valve head relative to the seat and, therefore, the

operating temperature, can be altered by turning the adjustment

which serves one end of the element.
