SOLAR SPRING SOLAR PUMPS
MAINTENANCE
Opening the pump
Note : Your Solar Spring pump usually needs to be opened only :
1) Where (after many years of use) parts subject to wear and tear may call for replacement during the course of a systematic preventive maintenance visit.In practice, intervention is limited to a long-term, periodic changing of the motor brushes part 344, and to the cleaning of the bleeder nipple part 308 WIGGLE THE WIGGLE WIRE OF THE BLEEDER PART 308 WHENEVER FOR ANY REASON THE PUMP IS WITH-DRAWN FROM THE BOREHOLE. Blockage of the bleeder is rarely critical for pump operation. In the unlikely case you should ever find the bleeder blocked please report this to your dealer.
2) Where, during installation, it is decided for purposes of optimisation to change cam size.
3) The pump series number is marked on a ring under below the ovoid chamber, under the rope hook.
1. BREAKAGE OF SEAL
YOUR SOLAR SPRING PUMP IS USUALLY SEALED FOR YOUR PROTECTION. We strongly recommend that only authorised maintenance operators maintain your pump. Breakage of the pump seal by unauthorised operators is considered to be a serious breach of trust and will normally lead to suspension of all conditions and benefits under the guarantee coverage. In presence of binding legislation contrary to the contents of this clause 1 of this section, the minimum legislative conditions shall prevail.

3. HOW TO OPEN THE PUMP
Tools required : Spanner 8 MA; (optional) pump body clamp (907);(optional ) a vice
Step one
Remove the self-locking nuts (312) then the tie-rod U strap washers (313) from the flange (314) of the ovoid chamber .
Note : It is not usually necessary to remove the safety rope from bracket on the flange (314) or to touch the rapid coupling (301) or the feed pipe at the pump outlet.
Step two
Place the pump body clamp (907) if available in a vice (if available) to stabilize the pump.
Step three
Ease the flange (314) off the threaded ends of the tie-rod "U" straps (362) and slide the flange (314) along the electric cable to a point of rest.
Note : It is not usually necessary to remove the ovoid (319) or the ovoid centering piece (320) from the ovoid chamber (316)
Step four
Remove the filter (321).
Step five
The valve chamber (326) and the motor shroud (358) may be tight where the "U-straps" (362) have been overtightened, slightly deforming them or the filter (321).
For access to the valve chamber (326) ease the valve chamber (326) off the pump body group (363 etc) by freeing it from the upper body "O" ring (331).
For access to the motor, ease the motor shroud (358) off the pump body group (363 etc) with a screwdriver. The parts fit together tightly and it may be necessary to clamp the pump body (322) around its widest part (the lower ring) and pull firmly on the motor shroud (358) or vice versa.
YOU NOW HAVE ACCESS TO THE MOTOR GROUP
Refer to substitution of the motor brushes
WARNING!
There is oil inside the pump body group. Refer to page 04.24 of this section for more information. Do not remove the pump body group (363 etc) off the pump cam shaft (338) or open the piston groups (347-357) without referring first to page 04.24.
