Instructions
1. Before installing make sure the piping is clean and free of debris. When installing take care to not allow pipe tape
or similar items to enter the product.
* Debris can affect proper operation and performance
2. Check the condensate inlet, condensate outlet, motive inlet, and vent outlet ports before connecting piping.
3. The DD6 must be installed with the vent and motive vertical and the condensate inlet and outlet horizontal.
* The product will not function properly if not installed in the correct orientation
4. Connect pipes securely
5. When connecting pipes unions or flanges should be used close to the DD6 connections. This reduces the
amount of time needed for maintenance and repair.
6. Avoid water hammer. If water hammer is experienced it could injure personnel or damage the equipment.
7. Do not disassemble product. If the product is disassembled the function or performance of the unit could be
compromised.
8. Attach strainer with blow down valve on motive steam inlet.
9. Attach check valve on condensate inlet and discharge.
10.Attach the motive drip trap to the steam motive line.
11.Provide clearance for future maintenance.
Start-up procedures
Caution
Make sure all connections are secure before opening valves. Open valves slowly to reduce the chance of
water hammer
1. Open isolation valve(s) in condensate discharge.
2. Open isolation valve in equalizing line.
3. Open motive isolation valve. Confirm that the steam does not flow into the pump body or equalizing line by
checking pressure gauges.
4. Open the isolation valve on the thermostatic air vent.
5. Open the isolation valve on the condensate inlet.
6. The start-up is complete if the Double Duty Six performs trap operation or pump operation and is confirmed by
use of the gauge glasses and pressure gauges.
Maintenance and Inspection
Most failures occur because of debris in the piping.
Caution
Before starting any maintenance make sure the Double Duty™ 6 is completely isolated from the system.
