Lochinvar Solar Electric Water Heater Installation And Operating Instructions

INSTALLATION AND OPERATING INSTRUCTIONS
This solar electric water heater's design is certified by Underwriters
Laboratories (UL) and listed in accordance with UL 174. C-UL listed in
accordance with Canadian National Standard C22.2, No. 110-M90.
This water heater must be installed in accordance with local codes. In the
absence of local codes, install this water heater in accordance with the
N.E.C. Reference Book (latest edition).
The warranty for this water heater is in effect only when the water heater
is installed, adjusted, and operated in accordance with these Installation
and Operating Instructions. The manufacturer will not be held liable for
damage resulting from alteration and/or failure to comply with these
instructions.
This water heater has been designed and certified for the purpose of
heating potable water. The installation and use of this water heater for any
purpose other than the heating of potable water, may cause damage to the
water heater and create a hazardous condition and nullify the warranty.
Do not use this appliance if any part has been submerged in water. The
plumbing professional responsible for the installation of this water heater
should be contacted to inspect the appliance and to replace any part of the
control system, including thermostat (if equipped), which has been
submerged in water.
A sacrificial anode is used to extend tank life. Removal of this anode, for
any reason, will nullify the warranty. In areas where water is unusually
active, an odor may occur at the hot water faucet due to a reaction
between the sacrificial anode and impurities in the water. If this should
happen, an alternative anode may be purchased from the supplier that
installed this water heater. This alternative anode will minimize the odor
while protecting the tank. Additionally, the water heater should be
flushed with appropriate dissolvers to eliminate any bacteria.
WARNING
Hydrogen gas can be produced in a hot water system served by
this water heater when it has not been used for a long period of
time (generally two weeks or more). Hydrogen gas is extremely
flammable. To reduce the risk of injury under these conditions,
it is recommended that the hot water faucet be opened for
several minutes at the kitchen sink before using any electrical
appliance connected to the hot water system. If hydrogen is
present, there will probably be an unusual sound, such as air
escaping through the pipe as the water begins to flow. There
should be no smoking or open flame near the faucet at the time
it is open.
Water heaters are heat producing appliances. To avoid damage or
injury, there shall be no materials stored against the water heater
and proper care shall be taken to avoid unnecessary contact
(especially by children) with the water heater. UNDER NO
CIRCUMSTANCES SHALL FLAMMABLE MATERIALS,
SUCH AS GASOLINE OR PAINT THINNER BE USED OR
STORED IN THE VICINITY OF THIS WATER HEATER
OR ANY LOCATION FROM WHICH FUMES COULD
REACH THE WATER HEATER.
LOCATION
This water heater must be located in an area where leakage of the tank or
water line connections and the combination temperature and pressure
relief valve will not result in damage to the area adjacent to the water
heater or to lower floors of the structure. When such locations cannot be
avoided, a suitable drain pan must be installed under the water heater. The
drain pan must be no greater than 1 1/2 in. (3.8 cm) deep and have a
minimum length and width of at least 4 in. (10.2 cm) measured from the
jacket of the water heater. The drain pan, as described above, can be
purchased from your plumbing professional. The drain pan must be piped
to an adequate drain. The piping must be pitched for proper drainage.
WATER CONNECTIONS
Before proceeding with the installation, close the main water
supply valve.
After shutting the main water supply valve, open a faucet to relieve the
water line pressure to prevent any water from leaking out of the pipes
while making the water connections to the water heater. After the
pressure has been relieved, close the faucet. Make the proper plumbing
connections between the water heater and the plumbing system in the
house. Install a shut-off valve in the cold water supply line.
If sweat fittings are to be used, DO NOT apply heat to the
nipples on top of the water heater. Sweat the tubing to the
adapter before fitting the adapter to the water connections. It is
imperative that heat is not applied to the nipples containing a
plastic liner.
If this water heater is installed in a closed water supply system, such as
the one having a back-flow preventer in the cold water supply, provisions
shall be made to control thermal expansion. DO NOT operate this water
heater in a closed system without provisions for controlling thermal
expansion. Your water supplier or local plumbing inspector should be
contacted on how to control this situation.
