1. Type TM Parallel Systems are factory pre-assembled and
tested and include large and small thermostatic water
mixing valves which function as a system to meet both
high and low demand for tempered water.
2. System should be installed at a location where it can
easily be cleaned, adjusted or repaired.
3. System supplies must be connected as shown (Hot-left,
Cold-right). Exercise caution when soldering.
