7.1 Pipe material
Use only the following materials for the pipes:
1. Copper is recommended
2. Stainless steel
3. PE or PVC – ensure that the appropriate steps are taken to protect the pipe along its
length.
The proper way to seal the European fittings can be done with any of following steps.
1. Pipe sealing cord. There are a number of brands available, however we use Loctite
55
2. Teflon Tape and a Anaerobic sealant.
3. Teflon Tape an Nylog sealant.
As with any sealant, the application instruction must be followed for proper use.
7.2 Relation of pipe diameter to distance between chiller and IFP
Use 2” (R2, DN 50 or 54-mm copper) for up to 25 meters (82 ft.) of straight pipe.
Use 2 ½” (R21/2, DN 65 or 64-mm copper) for up to 45 meters (147.6 ft.) of straight
pipe.
Distances exceeding 45 meters (147.6 ft.) are not permitted at using ECO and IFP.
7.3 Dimensions of the connections
Both the coolant return (water/ethylene glycol mix) from the IFP and the coolant supply
(water/ethylene glycol) to the IFP need to have a 2” internal thread.
To connect them, use a crossover with a 2” external screw thread or preferably a fitting
with a 2” external screw thread (two crossovers are attached to the pump/chiller and two
at the IFP panel).
7.4 Inflow and outflow
Verify that the inflow and outflow pipes are attached correctly (do not confuse).
The inflow is FROM the IFP. The outflow is TO the IFP.
The connections are labeled (see photograph).
On the Chiller inflow and outflow use the brass-fittings.
