InSinkErator 152 - Manual (Page 6)

This appliance must be grounded. In the event of a malfunction or breakdown, grounding
provides a path of least resistance for electric current to reduce the risk of electric shock. This
appliance is equipped with a cord having an equipment grounding conductor and a grounding plug.
The plug must be plugged into a three pin receptacle that is properly installed and grounded in
accordance with all local codes and ordinances. Have a licensed electrician check for ground
continuity of the electrical supply system to insure proper grounding of the water heater.
Temperature and Pressure Relief Valve. This valve must be marked with a maximum set
pressure not to exceed the marked maximum working pressure of the water heater. Install the
valve into an opening provided and marked for this purpose in the water heater, and orient it or
provide tubing so that any discharge from the valve will exit only within 6 inches above or at any
distance below the structural floor and cannot contact any live electrical part. This discharge
opening must not be blocked or reduced in size under any circumstances.
Check the metal tag on the relief valve and compare it to the heater’s rating plate. Pressure
rating of relief valve must not exceed the working pressure shown on the rating plate of the
heater and the A.G.A. hourly Btu rated temperature steam discharge capacity of the relief valve
shall not be less than the input rating of the heater. No valve is to be placed between the relief
valve and tank. Do not plug the relief valve.
The drain line connected to the valve must not contain a reducing coupling or other restriction
and should terminate near a suitable drain to prevent water damage during valve operation.
Discharge line shall be installed to allow complete drainage of both the valve and line. Do not
thread, plug or cap the end of the drain line.
Property Damage: To reduce the risk of excessive pressures and temperatures
in this water heater install temperature and pressure protective equipment
required by local codes but not less than a combination temperature and
pressure relief valve certified by a nationally recognized testing laboratory that maintains periodic
inspection of production of listed equipment or materials, as meeting the requirements for Relief
Valves and Automatic Gas Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22.
Personal Injury: “Insulation Blankets” are available for external use on
electric water heaters. But are not recommended by InSinkErator.
Property Damage: Hydrogen gas can be produced in a hot water system
served by this heater that 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
connected to the hot water system be opened for several minutes before using any electrical
appliance. 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.
If you choose to ignore our recommendations and install an insulated blanket on this heater
you must adhere to the following precautions in order to prevent serious injury or death to
yourself or others: (1)The junction box, external wiring, thermostats or heating elements on electric
water heaters must not be covered; (2)The temperature-pressure relief valve must not be covered;
(3)Operating instructions, installation or safety related labels must not be covered; (4)The American
National Standards & Federal Laws pertaining to water heaters require that instructions and safety
labels remain on the water heater proper. Do not remove instructions or safety labels from the
heater; (5)InSinkErator will not be liable for any incident resulting from the use of insulation
blankets; (6)Water and/or condensate can collect in an insulation blanket. InSinkErator will not be
liable for any rust or corrosion damage caused by the installation of insulation blankets.
CARE AND USE
Anytime the water heater is not used for extended
periods of time, unplug and drain unit. If it is below
freezing you will need to unplug the unit and drain it.
■ Disconnect power from unit.
■ Turn on “hot” faucet until water runs cool.
■ Shut off cold water supply to heater.
■ Leave hot faucet open to bleed off water pressure.
■ Remove drain screw from front-bottom of tank with
screw driver.
■ Drain water from tank into suitable container.
■ Leave the drain screw open during shut down.
■ Close hot water faucet.
■ To place back in working order, follow
filling instructions.
SEASONAL STORAGE/DRAINAGE
Periodically drain the tank to help prevent sediment buildup.
See draining instructions.
The temperature and pressure relief valve should be
checked periodically to ensure it operates properly. Lift the
level at the top of the valve to see if the valve opens and
closes properly.
MAINTENANCE
Check the things you can do yourself:
■ Be sure water heater is plugged firmly into
appropriate receptacle or is properly electrically
connected in some other manner.
■ Be sure fuses and circuit breakers are in good order.
■ Reread instruction booklet to assure that you are
using correct operation procedure.
■ Many unnecessary service calls result in the service
agent doing what the owner can do for himself.

Heating element has a thermostat which is factory set at
120˚F (49˚F) unless specified differently by
state requirements.
■ Turn off the heater electrical supply.
■ Unplug power cord.
■ Remove front panel.
■ Move temperature indicator on thermostat to
desired temperatures.
■ Replace panel, plug in power cord and turn on heater
electrical supply.
A non-adjustable high temperature limit control operates
before steam temperatures are reached. The high limit is
in the same area as the thermostat and must be reset.
Property Damage: Because the
high limit operates only when
abnormally high water
temperatures are present, it is important that a service
agent be contacted to determine the reason for the high
limit operation before resetting the high limit.
ADJUSTING THE THERMOSTAT
Personal Injury: The consumer
product safety commission
recommends temperatures of
130 ˚ F or lower setting the temperature higher will
increase the risk of scald injury.
Personal Injury: The water
passing out of the valve during
this check may be extremely hot.
Collect discharge in appropriate containers.
