Pre-installation check list

Check local codes for plumbing and roof load requirements. Installation must meet all local code requirements for penetrating structual members and fire rated assemblies, obtain all applicable permits.

Properly plan the installation and discuss the proposed location of the collector with homeowner to avoid any possible conflicts.

Make sure you have all necessary materials at the job site before starting the installation. Proper planning reduces labor and material costs.


Problem

Cause

Solution

Water keeps cold

during sunny day

1.There exists shelter above the heat collector or tubes seriously dirty.
2.Upper and lower valves are not tightly closed, so the cold water flows in continuously.

1.Take off the shelter or move the heater awayfrom

the current location, and clean the tubes.
2.Changes the valves.

Water tank cannot reach

the full level with water flow

1.The pressure of tap water is not high enough.
2.water leakage of pipe.
3.water leakage of tank.

1.Add a small water pump.
2.Change the pipe.
3.Find the solution for leakage of tank.

Water leakage of tank

1.Damage of seal ring or was not correctly positioned while assembly.
2.Crack of the inner layer of tank.

1.Replace the steal ring or re-position it.
2.Replace the inner layer of tank with a new one.

Water is cold one

minute but not the

next during taking shower

The pressure of the tap water is not stable

Fumish on roof one supplementary water tank

which can be functional as water storage,

water pressure stabilizer.

No hot water supply

in winter time

1.Pipe line frozen.
2.The weather is too cold to heat up the water.
3.Took no measure to the heat preservation of pipe

1.Distributor or producer helps do heat

preservation (not for free).
2.Evacuate the water in pipe with hot water,

and refill the water in the morning.
3.Furnish pipe with an electrical heating strip.
4.In very cold weather, turn on a little the hot water valve to keep

a small flow of hot water to avoid freeze of water.
