INSTALLATION – SOLAR CONTROL UNIT
SOLAR STORAGE TANK WITH RAISED SOLAR HOT INLET
Numbers in parentheses
To connect the solar cold pipe and mount the solar control unit on a solar
storage tank with a raised solar hot inlet (and raised heating unit):
•
Assemble a ½" x ½" hex nipple (1) into the branch outlet of the 4 way tee (2)
(ensure the compression end of the nipple is exposed) and the ½" x ¾" hex
nipple (3) in the end of the 4 way tee, so that when the assembly is fitted to
the cold water inlet of the solar storage tank, the compression nipple (1) is
orientated vertically upwards and the cold sensor housing is orientated to
the rear of the solar storage tank.
•
Fit the assembly to the solar cold water outlet of the solar storage tank.
•
Fit the ½"plug (15) into the end of the 4 way tee.
•
Connect the DN15 preformed pipe (4) to the branch tee connection, using
the compression nut (5) and olive (6) provided, ensuring the longer straight
end is orientated upwards.
•
Insulate the preformed pipe (4) with the 280 mm long x 12 mm diam
insulation (12) provided, ensuring the insulation is pushed down the full
length of the pipe.
•
Fit a ½" x ½" hex nipple (1) to the outlet of the circulator (7) mounted in the
solar control unit (8) (ensure the compression end of the nipple is exposed).
•
Locate the solar control unit (8) by connecting the DN15 preformed pipe (4)
to the nipple on the inlet of the circulator (7) using the compression nut (5)
and olive (6) provided.
•
Secure the solar control unit (8) to the solar storage tank using the four
screws (9) provided.
•
Connect the solar cold pipe (to the collector) to the nipple (1) on the outlet
side of the circulator (7) using the compression nut (5) and olive (6)
provided.
•
Insert the cold sensor probe (10) into the cold sensor housing on the 4 way
tee (2), ensuring the 'O' ring is in position on the probe. Lock it into position
with the locking washer and clip provided.
•
Connect the hot sensor lead (from the solar collector installation) to the hot
sensor cable connector at the underside of the solar control unit (8).
