Access To The Protection Fuse; Starting Up; Before Starting Up, Check - PSA ZODIAC Uranus+ Manual De Instalación Y De Uso

5.3 Access to the protection fuse

1) WARNING! Switch off the appliance!
2) remove the cover from the Uranus+,
3) disconnect the regulator,
4) remove the regulator cover,
5) remove the protection fuse (T3,15AH250V).
Notice: neither display nor operation if out of order

6. STARTING UP

Note: for primary heating connection, two pin connections for soldering are also delivered for 20/22 (models UP 35-
70) and for 26/28 (models UP 120-240).

• the hydraulic fittings are correctly tightened,
• there is no leak,
• the appliance is stable,
• the connections of the electric cables are correctly tightened. Incorrectly tightened cables may
cause overheating of terminals,
• the appliance is correctly connected to the ground,
Note: after a long stop, check if the circulation pump is not blocked, in this case, before switching on, undo the
screw in the front of the circulator (warning!
screwdriver.
6.2 Starting up
• open valves 1, 2 and 3 wide,
• start the filtration pump,
• check the pool water circulation in the exchanger,
• make a first by-pass adjustment to respecter more or less the nominal secondary water flow rate:
- valve 1 lightly closed to increase the filter pressure by 200 to 300 g,
• check the filling and degassing of the heating circuit,
• switch on the 30 mA différentiel circuit breaker, at the head of the line,
• set the required temperature on the display to be on demand ("reg" light flashing) see§ 5.2,
• press key ,
• adjust the by-pass for the good operation of the heater (to avoid short cycles), by playing with valve
