SECTION 2 - PRE-STARTUP AND SYSTEM OPERATING PROCEDURES
OPERATING INSPECTIONS
By following a regular inspection using the display
readings of the Microcomputer Control Center, and
maintenance procedure, the operator will avoid serious
operating difficulty. The following list of inspections
and procedures should be used as a guide.
Daily
1. Check OptiView™ Control Center displays.
2.
If the compressor is in operation, check the bear-
ing oil pressure on the
COMPRESSOR
Screen.
Also check the oil level in the oil reservoir. Oper-
ating oil level should be in the "Operating Range"
identified on the vertical oil level indicator label .
Drain or add oil if necessary.
3. Check entering and leaving condenser cooling
liquid pressure and temperatures for comparison
with job design conditions. Condenser liquid tem-
peratures can be checked on the
SYSTEM
Screen.
4. Check the entering and leaving chilled liquid tem-
peratures and evaporator pressure for compari-
son with job design conditions on the
SYSTEM
Screen.
5.
Check the refrigerant condenser saturation tem-
perature (based upon condenser pressure sensed
by the condenser transducer) on the
SYSTEM
Screen.
6.
Check the compressor discharge temperature on
the
SYSTEM
Screen. During normal operation
discharge temperature should not exceed 220°F
(104°C).
7. Check for any signs of dirty or fouled condenser
tubes. (The temperature difference between wa
-
ter leaving condenser and saturated condensing
temperature should not exceed the difference re
-
corded for a new unit by more than 4°F (2.2°C).
8.
Complete a visual inspection of the Turbine for
external damage or leaks.
9.
Inspect the Turbine for unusual vibration or noise.
10. The turbine oil temperatures should be checked
several times a day. On KG turbine design oil
temperature in the bearing oil should be between
130° and 180°F (54°C - 82°C). Cooling water
flow should be adjusted to maintain this range.
On KD turbines the oil supply from the oil cooler
to the turbine bearings should be between 110°
- 120°F, (38°C - 49°C). Adjust cooling water as
necessary.
11. Check oil pressures on the KD turbine lubrication
system every one or two hours.
12.
