Quarterly Checks
•
Compressor oil levels
•
Remove and clean all waterside strainers.
•
Check water fl ow rates and pressure drops across
evaporators and condensers
•
Check the brine concentration.
•
Verify graphical data and trending
•
Properly document all data
Annual Checks
•
Cleaning-In-Place of heat exchangers if suspected
scaling issues or clogged
•
Perform leak tests on all refrigerant circuits
•
Check all water fl anged connections for wear or leaks.
•
Check for evaporator circuit insulation for
any damage.
•
Implement oil analysis if deemed necessary
•
Verify all electrical connections are intact and no
sight of electrical damage is present.
•
Check and test all safeties (mechanical and software)
•
Verify sensor accuracy
•
Properly document all data
Condenser and Evaporator Cleaning Procedure
The following instructions for Cleaning-In-Place (CIP) of
the evaporator and condenser is based on the GDS-C40
or GDS-C92 CIP machine available from Goodway®. Visit
www.goodway.com/waterfurnace-calculator for determining
the correct amount ScaleBreak-MP descaler required for a
cleaning the heat exchangers.
Procedure:
1.
Disable the unit from the Primary controller HMI
and turn off power to the unit from the power
switching gear.
2.
Close Manual Isolation valves and verify that the
Actuated valves are also in the close position. If
Actuated valves are still open, manual overwrite the
valve position.
3.
Remove the grooved elbows shown in the inlet and
outlet of each unit.
4.
Connect the GDS-MSA (Goodway) adapter with the
bottom adapter offset is set the lowest position pos-
sible and the top adapter is set to the highest position
possible. This ensures that no air pockets are created
during the fl ushing procedure.
5.
Attach the circulation hoses. Pump the descaling fl uid in
the low side and return through the top side.
6.
Fill the heat exchanger with water and perform a hy-
drostatic test. If no leaks are present, proceed with the
descaling procedure.
7.
Bleed off enough water equal in volume to the descal-
ing solution needed.
8.
Reversed the fl ow every 15-20 min.
9.
Circulate the Scale Break – MP solution for the recom-
mended time frame as indicated by the calculator.
10. Once circulation time is completed, begin the fl ushing
process.
11. Ensure that the pH levels are safe for discharge and
follow your local regulations for discharge. Neutralize
the solution using ScalBreak Neutralizer if pH balancing
is required.
12. Turn off your circulation pump, remove the return hose
and place put it in a drain.
13. Add fresh water to the pump recirculation bucket and
start the pump.
14. Continue running clean water through the BPHE for 10
minutes or until the return water is running clean.
15. Disconnect your hoses and remove the adapters.
16. Reinstall the grooved pipe elbows.
17. Remove and clean the strainer baskets and re-install.
18. Power and enable the chiller.
19. Open manual isolation valves.
