Manifolds & Pipe Connections

Manifolds

The manifold for the slinkies

®

should be placed on the outside wall of the building, with the heat pump on the other side of the wall. It is strongly recommended

that the manifolds are NOT situated inside a building, as this would require insulation. On the slinky

®

manifold, each end of each slinky

®

is terminated in a 32 mm

to 28 mm reducer which is connected to a 28 mm compression valve. Each of these valves is connected to either a "feed header" or "return header". It is

important that the effective length of each slinky

®

is the same, to ensure even flow across them all; plumbers call this principle "reverse return".

Connecting pipe to the manifold

The pipe must be cut squarely, and neatly, and any burrs inside or outside removed. A proper plastic pipe cutter should be used. Each slinky

®

manifold is supplied

with copper ferules, one of which must be inserted into the end of each pipe. These ferules act as support sleeves so that the plastic pipe is not crushed by the

olive in the 32 to 28 mm reducers. It is essential that the slinkies

®

must be the same length to ensure even water flow. The slinkies

®

are all supplied in identical

lengths - they must not be cut to different lengths.

The pipe must be pushed all the way into the reducers, before the nut is tightened. Two spanners must be used to tighten the reducers - one to hold the body

of the reducer, and one to turn the nut. As the nut is tightened, the copper or brass olive is compressed onto the plastic pipe, sealing the joint. A jointing

compound such as Stag

®

may be used on the joints. For it to be effective it must be applied to the pipe before it is inserted into the reducer to achieve

maximum coverage.

Connecting the manifold to the heat pump

All standard twin slinky

®

manifolds are supplied with 28 mm Speedfit

®

push-fit connectors for connection via 28 mm Hep

O

®

or similar plastic pipe systems to

the heat pump. This pipe can be purchased from any plumbers merchants. The pipes should be insulated using "vapour barrier" (such as Armaflex

®

) insulation

once inside the building to prevent dripping. Any pipe outside the building need not be insulated since the circulating fluid contains anti-freeze.
