2.3. Screw cover with return line connection ¾" and fine filter 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 fine filter 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 filter unit with large dirt collection vessel (accessory art. no. 115323,
Fig. 4)
Fasten the fine filter unit to the return line connection (2), connect the return
line to the fine filter 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 flow direction
with the valve handle.
2.6. Flow direction changeover valve (accessory art. no. 115326, Fig. 6)
The flow direction changeover valve serves for clearing deposits/sludge in solar
stations and underfloor heating. Screw the flow direction changeover valve with
connection (P) to the pressure line connection (1). Connect connection (R) of
the flow direction changeover valve and the return line connection (2) with the
enclosed ½" T100 EPDM fabric hose. The two "solar station" connections on
the flow 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 toggle lever on the flow direction changeover valve. Deposits/sludge are
loosened by the generated pressure pulses.
3. Operation
Do not switch the Solar-Push K 60 pump on until it is filled completely with
liquid. Do not allow the pump to run dry! Procedure for filling the Solar-Push K
60: The plastic tank (3) must be filled 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, refill 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 fine filter (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 flushing 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 filling and flushing 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 fine filter (7).
The pressure relief valve (8) is available as an accessory for the REMS Solar-
Push K 60.
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 filling and flushing 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 outflowing transported media. Collect
outflowing transported medium immediately and dispose of it in accordance
with the national regulations that apply.
To flush heavily contaminated systems, e. g. underfloor heating and to clear
slurries, use a fine filter unit with a large dirt collection vessel (accessory) (page
2.4.) or a screw lid with return connection ¾" and fine filter 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
Pull out the mains plug before carrying out maintenance or repair work!
This work may only be performed by qualified personnel.
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 fine filter 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
file filter, remove the filter screen and clean both under running water or with
compressed air. Replace damaged filters.
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

This work may only be carried out by qualified personnel and with original spare
parts.
