Installation


1. Handle carefully while transporting, unloading and lifting the system to the terrace.
2. Install the system where it gets maximum sunlight.
3. Assemble the mounting frame of the tank and/ or manifold such that the ETC tubes are facing towards South.
4. Put the Hot water/ Manifold over the frame. Check whether the tank/ manifold holes are facing the holes of the Bottom Support Bracket.
5. Put the Bottom Caps into the Bottom Support Holes.
6. Put anti-dirt seal over the ETC Tubes.
7. Apply some oil or soap water to the Silicon Rubber Grommets and to the end of the ETC Tubes as lubricant.
8. Fix one ETC tube to each end of the Tank/ manifold by slowly screwing it into the tank.
9. Push the ETC Tube down till it gets securely placed in the Bottom Cap.
10. If the alignment is ok. Tighten the bolts under the tank to the frame.
11. Now install all the remaining ETC Tubes.
12. Connect the inlet-outlet pipes to the tank. Fix a non Return Valve (preferably horizontal) and a ball valve to the inlet pipe of the tank as shown in the figure. If it is a manifold system , connect the manifolds to the tank and connect inlet outlet pipes to the tank.
13. Fill up the tank with cold water when the ETC Tubes are cold. Specially early morning before sun rise or after 10 O’clock at night. Check for any leakages. Sometimes, the Silicone Rubber Garmmets are displaced while inserting the ETC Tubes. If there is any leakage form the Anti-dirt seal, remove the tube, place the silicone rubber ring on its seat and reinsert the tube.


Caution


The empty system should never be filled with cold water in the afternoon or when the Tubes are hot. Either fill it up before 7 am in the morning or After 10 O’clock at night. Otherwise, the ETC Tubes are prone to crack due to temperatuere shock.


Troubleshooting


Indications

Possible Reason

Remedies

  1. No water in the hot   water tap.

 

  a.  Empty cold water tank
  b.  Gate valve / ball valve
  closed
   c. NRV not operating
   d. Air locked in the hot
  water- pipe.
  e. Cold/ hot water line
  choked

  Fill up the tank
   Open the valve
  Replace NRV
  Remove air lock
  Clean pipes

 

  2. Low hot water   temperature

  a. Poor Sunlight
  b. Over consumption of
   hot water
  c. Excessive hot water   use
  during no sun hours.
  d. Tubes covered by dust
  e. Scale deposited in   tubes.
   f. Hot/ cold water mixing

  Wait till Sun gets brighter
  Regulate consumption
  Decrease usages during
  No-Sun hours
  Clean the tube externally
   Remove & clean tubes   internally
  Get mixer clock repaired   if necessary

  3. Not water coming out   through cold water pipe/   taps

  a. Defective NRV
  b. Defective cold-hot
  water mixer cock
  c. Cold and hot water
  lines connected
  together

  Repair/ replace NRV
  Repair/ replace mixer   cock

  Disconnect

  4. Water leaking through   tank.

  a. Silicon rubber grommet
  displaced / defective

  Place properly or replace   silicon rubber grommet.

Important


1. Never fill up the empty system when the tubes are hot. The best time to fill up the tank is before sunrise or after 3 hours of sunset.
2. If there is a wide time gap between 2 subsequent baths, the hot water stranded in the pipeline loses heat . keep the interval between two baths to the minimum.
3. The ETC tube can be descaled by a simple bottle cleaning brush. Periodical cleaning will maintain the operational efficiency of the system.
4. If the ETC tube changes its appearance and look hazy while, it indicates the ETC tube is broken or the vacuum is lost. This will render the tube useless. Get the tube replaced by any authorized person as early as possible.
