American Water Heater 318281-000 사용자 설명서

9

This solar water heater shall not be connected to any 

heating systems or component(s) previously used with a 

non-potable water heating appliance.
If this solar water heater is also used for space heating 

applications, all piping and components connected to the 

solar water heater shall be suitable for use with potable 

water.
This appliance has been design certified as a solar water 

heater complying with Standards for Safety - UL174 for 

the U.S. and can/csa-c22.2 No 110 F379.1 and F379.2 

for Canada. The particular application of this appliance 

described (above paragraph) may be subject to review and 

approval by local code officials.
Toxic chemicals such as used for treatment of boilers or non-

potable water heating appliances shall never be introduced 

into a potable water space heating system.

The solar water heater will work better if you keep the hot 

water runs short.  You will also get hot water faster and with 

less heat loss.
The illustration shows the correct valves and fittings that you 

will need to install the solar water heater. Threaded (3/4”) 

water connections are supplied through the tank top.

1.  Buy the fittings that you need to connect the pipes.  

Remember that you have to connect both the hot and 

cold water pipes.

2.  Apply a light covering of pipe joint compound to each 

outside thread before making connection.

3.  Connect the cold water supply pipe to the cold water inlet 

of your solar water heater as follows:

  a.  Look at the top cover of the solar water heater. The 

hot and cold connections are marked there.

 

b.  A non-metallic dip tube is supplied to carry cold water 

from the tank top to the bottom. Be sure that it is in 

the cold water inlet.

  c.  If using copper tubing, solder tubing to an adapter 

BEFORE you attach the adapter to the cold water 

inlet. DO NOT solder the cold water supply pipe 

directly to the cold water inlet connection. It might 

harm the dip tube.

 

d.  The cold water supply line must have a shut-off valve 

and union.  

4.  Use a union to connect the hot water supply pipe to the 

solar water heater’s hot water outlet.

Operating an empty or partially filled solar water heater will 

result in damage to the tank.
If a solar water heater is installed in a closed water system; 

such as one having a back flow preventer, check valve or 

water meter with check valve in the cold water supply line, 

means shall be provided to control thermal expansion. 

Contact the water supplier or local plumbing contractor on 
how to control this situation.
INSTALLATION IN RESIDENTIAL GARAGES 

 The solar water heater must be located and/or protected so 

it is not subject to physical damage by a moving vehicle.

1.  Close the solar water heater drain valve.  The drain valve 

is on the lower front of the solar water heater.

2.  Open the cold water supply to the solar water heater.  

NOTE: THIS VALVE MUST BE LEFT OPEN WHEN THE 

SOLAR WATER HEATER IS IN USE.

3. Fill the solar water heater until a constant flow of water 

runs out an opened hot water faucet.  This will let out 

air in the solar water heater and the piping.  Close the 

faucet after all air has been purged and the water comes 

out with constant flow..  You must not turn the electricity 

on until the solar water heater is full of water.  IF ANY 

AIR IS LEFT IN THE TOP OF THE SOLAR WATER 

HEATER, THE TOP HEATING ELEMENT WILL BURN 

OUT IMMEDIATELY.

4.  Check all the new water piping for leaks. Fix as 

needed.

Determine voltage and wattage from the rating plate 
attached to the solar water heater.  All external wiring, 
connection, and overcurrent protective devices must be 
provided and installed in accordance with the latest edition 
of the National Electrical Code, local codes, and local utility 
requirements.  The solar water heater must be electrically 

“grounded” by the installer.  A green ground screw has been 

provided on the solar water heater’s junction box.

The grounding electrode conductor shall be of copper, 

aluminum, or copperclad aluminum.  The material shall be 

resistant to corrosion, and shall be of one continuous length 

without a splice or joint.

Rigid metal conduit, intermediate metal conduit, or electrical 

metallic tubing may be used for the grounding means 

if conduit or tubing is terminated in fittings approved for 

grounding.
