Fig. 1. Maximum temperature characteristics of valves.
MOUNTING
The valve can be mounted in any position on a vertical
line. If the valve is mounted horizontally; the powerhead
must be even with or above the center line of the piping.
Make sure that enough room is provided above the
powerhead to remove the cover for servicing.
Fig. 2. Mounting positions.
Mount the valve directly in the tube or pipe. Make sure
that the flow through the valve is in the direction indicated
by the arrow stamped on the valve body.
On diverting valves, the three fittings or ports are labeled
on the bottom of the valve body casting. See Fig. 3. Port
AB is the inlet port and is open at all times. Port A is
closed when the valve is de-energized; port B is open
when the valve is de-energized. Refer to the equipment
manufacturer’s instructions to determine which port (A or
B) should be connected to the coil bypass.

diverting valves.
FLARE FITTING MODELS
Use new, properly reamed pipe, free from chips. The
valve body is threaded for standard 5/8 in. OD copper, 45
degree SAE flare fitting nuts. These nuts are not furnished
with the valve and must be obtained separately.
SWEAT COPPER MODELS
1. Use new, properly reamed pipe, free from dents or
corrosion.
2. Place the valve onto the pipe. Set the manual open-
ing lever to MAN. OPEN position before applying
heat. This protects the plug inside the valve by
removing it from the seat.
EXAMPLE: 150°F (66°C) IS THE AMBIENT TEMPERATURE AT THE VALVE,
235F (113C) IS MAXIMUM FLUID TEMPERATURE.
