SAFETY PRECAUTIONS

WARNING

When using electrical appliances, basic safety precautions should always be followed including the following:

Use stainless steel flexible hoses or copper tubes of 1/2” on the inlet and outlet.

DO NOT USE PVC, CPVC or plastic supply line directly to the heater.

The installation must be in compliance with the National Electrical Code , your local electrical and plumbing codes.

This appliance must be GROUNDED.

CONNECTED ONLY TO A CIRCUIT THAT IS

PROTECTED BY A RECOGNIZED GROUND-

FAULT CIRCUIT INTERRUPTER(GFCI).

This appliance is forbidden to be switched on if you think it may be frozen, as this could result in serious damage to the unit. Wait until you are sure that it has completely thawed out before you switch it on.

We highly recommend that you employ the services of a professional to assist you with this installation if you are not familiar with basic plumbing and electricity. Under no circumstances should you attempt to install, repair or disassemble the water heater without first disconnecting the electricity.

This appliance is not intended for use by persons (include children) with reduced physical sensory or mental capabilities, or lack of experience and knowledge, unless under careful supervision. Children should be supervised to ensure that they do not play with the appliance.

Install or locate this water heater only in accordance with the provided installation instructions.

Safety and energy conservation are factors to be considered when selecting the water temperature setting of water heater’s thermostat. Water temperatures above the

125°F (52°C) can cause severe burns from scalding.

Use this water heater only for its intended use as described in this manual.

This appliance MUST be permanently connected to the fixed circuit breaker and it must be installed vertically. DO NOT install near tinder or a strong magnetic field.

PG.1

SAFETY PRECAUTIONS

ATTENTION

It is extremely important to FLUSH the pipes to wash away sundries and residue in the pipes before connecting the water heater to it.

Increasing the water temperature setting may improve the cleaning performance of dishwashers.

Risk of Fire - Hydrogen gas can be produced in a hot water system served by this water heater that has not been used for a long period of time(generally two weeks or more).

HYDROGEN GAS IS EXTREMELY FLAMMABLE!!

To dissipate such gas and to reduce risk of injury, 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 be an unusual sound such as air escaping through the pipe as the water begins to flow. Do not smoke or use an open flame near the faucet at the time it is open.

Safety regulations require a factory setting no greater than 125°F (52°C) for all new water heaters. Therefore, if your old water heater was set to a hotter temperature than your new water heater with a factory setting of

120°F (49°C), the new water heater may seem to provide lower capacity than your old water heater. This can be corrected by increasing the temperature setting.

The user can adjust the temperature setting to meet their needs. Always read and understand the safety instructions contained in the manual before adjusting the temperature setting.

If the water heater is to remain idle for an extended period of time, the power and water to the appliance should be turned off and the water heater drained to conserve energy and prevent a buildup of dangerous hydrogen gas.

This unit has no power button, power can only be shut off at the circuit breaker or disconnect switch. The water heater and piping should be drained if they might be subjected to freezing temperatures. After a long shutdown period, the water heater’s operation and controls should be checked by qualified service personnel. Make certain that water is flowing to water heater again before placing it in operation.

Statement: ENVO does not assume any responsibility for the losses caused by the improper installation and behavior listed above or other improper operations.

INSTALLATION GUIDELINE

Make sure the appliance is intact, and the fittings are complete.

Please make sure the main power supply, water pressure, grounding condition, ammeter and wire reach the standard of installation requirement.

Clean all the impurities of the pipe by allowing water to flow for a few minutes before connecting the heater to the supply line. Any residue or dirt in the pipes may cause damage to the heater.

We strongly recommend installing a water filter before the inlet of heater. Hard water or water with high levels of minerals and alkali can cause damage to this unit. Water softening system is needed for this case.

It must be fitted with a pressure reducing valve adjacent to the entrance when the inlet pressure is higher than 150 Psi (1034kPa).

DO NOT install near tinder or a strong magnetic field. The appliance can be installed above or under the sink, and unit must only be mounted with inlet & outlet pointing downward or upward VERTICALLY near by the water fittings.

It is recommended to install the appliance no more than 4 ft from the point of use to save power.

Avoid locations that are prone to dampness, high humidity, moisture, or dust.

PG.4

INSTALLATION GUIDELINE

Install the water heater in a dry, clean area, as close to the target faucet as practically possible. Avoid installing in rooms that are subject to freezing temperatures or corrosive atmosphere. Long uninsulated hot water lines can waste energy and water.

NOTE: Make sure the water heater and hot water outlet pipe are out of the reach of children to avoid tampering with the controls or burn themselves on hot water outlet pipe.

Moving the water heater or other appliances to provide service to the water heater is not covered under warranty.

There must be sufficient clearance between any object and the top, rear and sides of the water heater in the event service is needed.

The controls and plumbing connections at front of unit must have clear access for operation and service.

Recommended Minimum Clearances:

12” above and below the water heater

6” in front and to both side of the water heater.

If a check valve is present on the inlet water line, it will create a “closed system.”

Heating water in a closed system creates an increase in pressure within the water system because the pressure is not able to dissipate in the main supply line. Referred to as “thermal expansion”, the rapid pressure increase can cause the relief valve to operate

(releasing water) during each heating cycle, potentially causing premature failure to the valve or even the water heater. The suggested method of controlling thermal expansion is to install an expansion tank in the cold water line between the water heater and the check valve. Contact your installing contractor, water supplier, or plumbing inspector for additional information.

A separate branch circuit with copper conductors, overcurrent protective device and suitable disconnecting means must be provided by a qualified electrician.

All wiring must conform to local codes or latest edition of National Electrical Code ANSI/NFPA

70.The voltage requirements and wattage load for the water heater are specified on the rating label on the front of the water heater.

The branch circuit wiring should include either:

1. Metallic conduit or metallic sheathed cable approved for use as a grounding conductor and installed with fittings approved for the purpose.

2. Nonmetallic sheathed cable, metallic conduit or metallic sheathed cable not approved for use as a ground conductor shall include a separate conductor for grounding. It should be attached to the ground terminals of the water heater and the electrical distribution box.

WARNING

It is recommended for this product to be installed by a licensed and qualified electrician in accordance with all applicable national, state, and local electrical codes.

Before installing this product, make sure the installation location has sufficient electrical power available to handle the maximum amperage load for the water heater.

Under no circumstances should you attempt to install, repair, or disassemble the water heater without first shutting off power directly at the fuse or breaker.

Proper ground connection is essential. The presence of water in the piping and water heater does not provide sufficient conduction for a ground. Nonmetallic piping, dielectric unions, flexible connectors, etc., can cause the water heater to be electrically isolated. Do not disconnect factory ground.

PG.5
