INSTALLATION
When Installing This Product...
1. Read these instructions carefully. Failure to follow them
-50 (149)
could damage the product or cause a hazardous condi-
-40 (119)
-30 (89.5)
tion.

CAUTION
-.1 (0.3)
1.
Disconnect power supply before connecting wiring
-0.05 (0.15)
to prevent electrical shock or equipment damage.
2.
Normally it is not necessary to remove the power-
head from the valve body during installation. If the
valve must be disassembled, be certain that it is
M9185A
reassembled with the water flow in the direction of
the arrow. Reversal of the powerhead results in
damage to the gear train.
3.
On 24V systems, never jumper the valve coil ter-
minals even temporarily. This can burn out the
heat anticipator in the thermostat.
