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
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
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 ROLLER 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 appli-
cation site must be considered and observed.
4.1. Maintenance
WARNING
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 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.
