AS NEEDED
Adding Octyl Alcohol - Octyl alcohol is usually
required when the leaving chilled water tempera­
ture starts to rise above design providing the
control set point has not been altered. Since a
rise in leaving chilled water temperature is also
an indication of fouled condensing water tubes,
use the following procedure to determine if
alcohol is required.
PROCEDURE
1. Remove a sample of solution from solution
pump service valve. If solution has no odor
of alcohol (very pungent), then octyl alcohol
should be added.
2. Add alcohol using the procedure outlined in
Carrier Standard Service Techniques, pub­
lication SM-16.
3. If alcohol is not required, refer to Trouble­
shooting Guide for symptoms of fouled tubes.
Log Sheets - We recommend that log sheets be
obtained from your Garrier representative and
that readings be taken periodically. They are
used to:
1. Familiarize operator with machine operation.
2. Be of assistance when planning maintenance.
3. Diagnose machine troubles.
Ordering Spare Parts - Order spare parts from
your nearest Carrier office. To speed up the
process of filling part orders, the following in­
formation must accompany the order:
1. Delivery address.
2. Machine size.
3. Machine serial number.
4. Part name, part number and quantity required.
5. Orders for pump parts must show the motor
serial number found on the motor nameplate.
