Regulus KPS1, Installation And Operation Instructions Manual

5.1 - Connecting the collectors

For collector mounting follow the instructions in chapter 

5.2. Fasten the first collector and lay the following one 

next to the first one, maintaining a sufficient gap. Then 

put the threaded fittings on both the upper and lower 

outlets and push the collector to the already mounted 

one until stop. Hold the fitting with a spanner (Fig. 24) 

to prevent turning, and tighten the nuts. Continue in the 

same way with further collectors. 
Put the insulation on the threaded fittings only 

after a successful leak test.

5.2 - Interconnecting the collectors

Hydraulic interconnection of collectors shall be done 

according to Fig. 23a. Maximum of 5 collectors may be 

connected with threaded fittings in a row. If there are 

more than 5 collectors in a row, a compensator shall be 

installed in the middle of the array. With a compensator, 

max. of 10 collectors in a row may be installed. The con-

necting pipes shall be lead the shortest way. The recom-

mended pipe diameters and flow rates through collector 

arrays are shown in Tab. 1.
Collectors may be also connected as shown in Fig. 

23b. This kind of connection is permitted when 

up to 3 

collectors are used and the max. flow rate is 1 l/min/

collector

. Then the cold liquid inlet is at one side bottom 

and the hot liquid outlet is at the same side top. Both the 

other ends shall be plugged..
A brass elbow shall be installed at the inlet to the collec-

tor array with a transition to the interconnection piping. 

At the outlet from the collector array, a brass pipe cross 

shall be installed that will enable connection to collector 

piping. The brass elbow, pipe cross and plugs are invol-

ved in Regulus connection kit, code 7710. 

All solar components must be carefully and safely sea-

led and must be made of material resistant to glycol and

temperatures up to 160 °C. For connection piping we

recommend using KOMBIFLEX stainless-steel flexible

pipes, or copper pipes joined by soldering.
