Product Identification

A red label should be on the front face of the thermal system.

1. Product Label

Figure 1.

This label contains information required to properly maintain, service and order parts for this product. If there is no label, look for a white label on the inside of the thermal system legs (Figure 2A) or the valve body vertical yoke (Figure 2B). When replacing the original thermal assembly or valve body, secure the old red label onto the valve or thermal system or ink the number onto the body.

Position Valve

2. Select valve location with sufficient clearance to allow maintenance. Install valve in line. The direction of the arrows on the valve body must match the direction of the water or steam flow.

For best results, we recommend installing the valve in a horizontal line, and in the upright position with bellows head above valve. The valve may also be installed in any position within 90° of upright.

Figure 4.

The direction of the arrows on the valve body must match the direction of the water flow.

Pipe the hot water to the bottom ‘B’ port, and the cold water to the upper ‘U’ port. The mixed water will exit the valve through the common ‘C’ port.
