Solar Storage Tank With Raised Solar Hot Inlet; To Connect The Solar Hot Pipe To The Solar Storage Tank - Rheem Solar Loline Water Heater Owner's Manual And Installation Instructions

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 Loline 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 400 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).

To connect the solar hot pipe to the solar storage tank:


Insulate the solar non return valve of the air bleed valve and solar non return valve assembly (11) with
the 50 mm long x 35 mm diam insulation (13) provided.

Fit the air bleed valve and solar non return valve assembly (11) to the solar hot water inlet of the solar
storage tank. Ensure the bleed valve outlet is pointing vertically downwards.

Connect a DN15 copper drain line to the bleed valve to carry the discharge clear of the water heater and
solar control unit (refer to
provided.

Fit a ½" x ½" hex nipple (1) to the exposed end (inlet) of the air bleed valve and solar non return valve
assembly (11) (ensure the compression end of the nipple is exposed).

Connect the solar hot pipe (from the collector) to the nipple (1) on the air bleed valve and solar non
return valve assembly (11) using the compression nut (5) and olive (6) provided.

Insulate the tee and bleed valve, from the solar hot pipe to the drain line of the bleed valve, with the
150 mm long x 35 mm diam insulation (13) and secure with the cable ties (14) provided.

Insulate the drain line from the bleed valve with closed cell polymer insulation or similar (minimum
thickness 13 mm). The insulation must be weatherproof and UV resistant if exposed.
