Example:
Stabilized Temperature 160°
Ambient Temperature -80°
Heat Rise 80°
The normal operating temperature range of this circuit
will be the typical ambient temperature range for the geo-
graphical area plus the heat rise calculated above. Ensure
that the operating temperature range is lower than 180° for
optimum operation of the attachment.
Troubleshooting
If adequate pump ow is available from the carrier pump(s)
but is not getting to the attachment, consult your service
representative and review the following:
1. Attachment valve(s) are not actuating. Review all elec-
trical connections that are part of the attachment kit.
2. Ensure proper voltage to the valve(s).
3. Ensure the REG port of the valve is not blocked.
4. Check to make sure the carriers main relief is set to
the manufacturers recommendation and that this value is
equal or greater than the attachment circuit relief.
5. If the valve will not turn off, check the drain (tank) line
of the valve to ensure that the pressure is 50 psi or less.
