IV. PRE-INSTALLATION CHECK LIST
1. Check local codes for plumbing and roof load requirements. Installations must meet all
local code requirements for penetrating structural members and fire rated assemblies.
2.
Obtain all applicable permits.
3.
Inspect the roof. If it is in poor condition, advise the homeowner before the installation
is begun.
4. Properly plan the installation by inspecting the attic and location of the conventional
water heater. Discuss the proposed location of ht system’s major components with the
homeowner to avoid any possible conflicts.
5. Make sure you have all necessary materials at the job site before starting the
installation. Proper planning reduces labor and material costs.

Warranty on
corrosion specifically states the “water must meet EPA Standards of Potable Drinking
Water and have a PH maintained between 7.0 and 9.0 at all times”. Some areas may
not have water quality that meets these warranty criteria. If water is too acidic, “pitting
corrosion” can occur. If the situation is prolonged, the corrosion action can result in “pin-
hole” leaks in the tubes. Pitting corrosion is always clear indication of aggressive water.
If there is a concern for water quality and the ability to maintain proper PH levels then
measures should be taken to properly condition the water before it enters the

. Water softener/conditioners work very well to relieve this problem.
If the situation cannot be resolved, then considerations should be taken as to whether
the installation should proceed.
V. INSTALLATION PRECAUTIONS
The following are important measures to follow to ensure a safe, trouble free installation.
1. Remove the temporary labels after installing the unit (i.e., “In”, “Out”, and “Do Not
Use Pipe Connections for Handles”).
2. Remove the plastic pipe caps before exposing the unit to full sunlight; otherwise
they may melt onto the inlet and outlet nipples.
3. Be careful of the inlet and outlet nipples during installation. The unit can dry
stagnate up to 400
0
F causing the nipples to produce severe burns if touched.
4. Do not lift or handle the unit by the copper inlet and outlet nipples. You could crack
a weld and cause the unit to leak. This is not covered by the warranty. Each
unit is pressure tested to 165 psig during manufacturing and again at 50 psig before
shipment.
