2.2. Connecting the electrical fi lling and fl ushing unit to the solar system
Connect one of the two fabric hoses to the pressure line connection (1). Connect
the 2nd fabric hose to the return line connection (2) of the plastic tank (3).
Connect the respective free end of the pressure or return line to the ball valves
of the solar system and open the ball valves. Close the connecting valve between
the two ball valves of the solar system. Fill the plastic tank (3) with transported
medium and open the ball valve (4). Plug the mains plug of the electrical fi lling
and fl ushing unit into the socket with a protective earth.
CAUTION CAUTION
Danger of injury due to escaping transported medium. Tighten the hose
screw connections and check for leaks regularly.
2.3. Screw cover with return line connection ¾" and fi ne fi lter bag 70 μm
(accessory art. no. 115220, Fig. 3)
Remove the screw cover (6). Replace the inner plate of the screw cover (6) by
an adapter (10). Screw the screw cover (6) with adapter to the plastic tank.
Insert the fi ne fi lter into the opening in the adapter, screw the screw cover with
¾" return line connection to the adapter, screw the return line to the return line
connection, close the return pipe (2) connection.
2.4. Fine fi lter unit with large dirt collection vessel (accessory art. no. 115323,
Fig. 4)
Fasten the fi ne fi lter unit to the return line connection (2), connect the return
line to the fi ne fi lter unit.
2.5. Changeover valve for alternative suction of the transport medium from
another tank (accessory art. no. 115325, Fig. 5)
Unscrew the line from the plastic tank (3) to the pump at the ball valve (4) and
screw on the changeover valve for alternative suction of the transport medium
at the ball valve (4). Connect one outlet of the T-piece to the pump line, connect
a line to another tank to the other outlet of the T-piece. Control the fl ow direction
with the valve handle.
2.6. Flow direction changeover valve (accessory art. no. 115326, Fig. 6)
The fl ow direction changeover valve serves for clearing deposits/sludge in solar
stations and underfl oor heating. Screw the fl ow direction changeover valve with
connection (P) to the pressure line connection (1). Connect connection (R) of
the fl ow direction changeover valve and the return line connection (2) with the
enclosed ½" T100 EPDM fabric hose. The two "solar station" connections on
the fl ow direction changeover valve are connected to the outlets on the solar
station with the two ½" fabric hoses belonging to the REMS Solar-Push. The
pressure line and return line to and from the solar station are switched by turning
the lever on the fl ow direction changeover valve with the pump running. Deposits/
sludge are loosened by the generated pressure pulses.
3. Operation
NOTICE
REMS Solar-Push is not intended/suitable for permanent connection to the
installation. Disconnect all hoses from the installation after completing the work.
REMS Solar-Push may not be operated unattended.
Do not switch the Solar-Push K 60 pump on until it is fi lled completely with
liquid. Do not allow the pump to run dry! Procedure for fi lling the Solar-Push K
60: The plastic tank (3) must be fi lled with liquid. The pressure line (1) and
return line (2) must be connected. Open the ball valve (4). Open the bleed
screw (9). Close the bleed screw (9) as soon as liquid emerges.
The pump of the Solar-Push I 80 also sucks dry.
Switch the pump on at the On / Off switch (5). Open and remove the screw
cover (6) on the plastic tank (3) so that the air can escape from the system.
Observe the liquid level in the plastic tank and, if necessary, refi ll with transported
medium so that no air enters the solar circuit. Flush the solar circuit with the
transported medium. At the inspection glass of the fi ne fi lter (7) or by looking
into the large opening of the plastic tank (6), check whether there are still air
bubbles in the transported medium. Continue the fl ushing process until there
is no more air in the transported medium.
Do not close the pressure and return lines of both pumps for longer than 60 s
because the pumps otherwise run hot and will be damaged.
Switch off the pump (5) after the end of the fi lling and fl ushing process. Close
the ball valves on the solar system, open the conneting valve between the two
ball valves of the solar system. Close the ball valve (4). On the REMS Solar-
Push I 80, reduce the pressure in the pressure line by opening the pressure
relief valve (8). On the REMS Solar-Push K60, reduce the pressure in the
pressure line by slightly unscrewing the inspection glass on the fi ne fi lter (7).
The pressure relief valve (8) is available as an accessory for the REMS Solar-
Push K 60.

CAUTION CAUTION
Danger of scalding at high transported medium temperature. Fill the system
only when it is in its cold state; cover the solar collectors if necessary.
First unscrew the pressure and return lines on the fi lling and fl ushing unit,
connect the open hose ends with a connecting piece, e.g. ¾" double nipple in
order to prevent transported medium from dripping of running out during trans-
port.
NOTICE
Avoid environmental damage from outfl owing transported media. Collect
outfl owing transported medium immediately and dispose of it in accordance
with the national regulations that apply.
To fl ush heavily contaminated systems, e. g. underfl oor heating and to clear
slurries, use a fi ne fi lter unit with a large dirt collection vessel (accessory) (page
2.4.) or a screw lid with return connection ¾" and fi ne fi lter bag 70 μm (acces-
sory) (see 2.3.).
NOTICE
Danger of frost: If the pump is exposed to temperatures ≤ 5°C, the pump body,
the plastic tank and the hoses must be completely emptied to avoid damage.
This procedure is also recommended at normal temperatures when the pump
is not used for long periods of time.
4. Maintenance
Notwithstanding the maintenance described below, it is recommended to send
in the electrical fi lling and fl ushing unit to an authorised REMS contract customer
service workshop for inspection and periodic testing of electrical devices at
least once a year. In Germany, such periodic testing of electrical devices should
be performed in accordance with DIN VDE 0701-0702 and also prescribed for
mobile electrical equipment according to the accident prevention rules DGUV,
regulation 3 "Electrical Systems and Equipment". In addition, the respective
national safety provisions, rules and regulations valid for the application site
must be considered and observed.
4.1. Maintenance
WARNING
Pull out the mains plug before maintenance work!
Clean the pump regularly in order to prevent the pump parts from sticking,
particularly if they are not used for a n extended period. Store the pump in a
frost-proof location. Check hoses, hose connectors and seals for damage before
every use. Do no used damaged hoses and seals.
Check the fi ne fi lter of the pump for contamination regularly through the sight
glass (7) and clean if necessary. To do this, unscrew the sight glass (7) on the
fi le fi lter, remove the fi lter screen and clean both under running water or with
compressed air. Replace damaged fi lters.
Clean plastic parts (e.g. housing) only with REMS CleanM machine cleaner
(Art. No. 140119) or a mild soap and a damp cloth. Do not use household
cleaners. These often contain chemicals which can damage the plastic parts.
Never use petrol, turpentine, thinner or similar products for cleaning.
Make sure that liquids never get onto or inside the pump motor.
4.2. Inspection / maintenance
