Remove the tube clip, slide broken tube out, and carefully pick up any glass pieces.
Please wear protective gloves when handling the broken glass. When removing the
tubes, the rubber ring in the manifold casing may pop out. Just return the ring into place
before inserting the new tube.
Avoid touching the glass wool insulation with bare hands, as it can cause mild skin
irritation.
The new tubes should already have heat transfer fins inserted, so slide the new tube into
place, taking care to guide the heat pipe into the slot between the fin and the glass wall.
Normally the heat pipe does not need to be removed from the manifold.

1. If tank is not full, you can add water anytime. Please add water after using hot water.
If tank is exposed without water longer than 15 minutes, do not feed water. Please make

from breaking due to substantial difference in temperature.
2. In order to avoid scalding, please turn on the cold water valve first, then turn on the
hot water valve, then adjust the cold water valve and hot water until reaching the
suitable hot water temperature if the mixing valve is not available.

water can enter into the water tank slowly.
4. Getter should be mirrorlike in appearance, or else tube is not in a vacuum condition.
If it appears misty, please change the tube.
5. Air vent in the tank mustn’t be jammed, in order to avoid swelling or broken tank.
6. Keep the tank full while winding.
7. In winter, keep the pipeline insulated to protect it from freezing in cold areas and
start the electrical cable installed on the inlet and outlet pipe.
8. Fix the frame carefully against strong winds to prevent accidents.
