Example:
Stabilized Temperature
Ambient Temperature
Heat Rise
The normal operating temperature range of this circuit
will be the typical ambient temperature range for the
geographical 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 flow 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
electrical 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.
