Mounting Options:

The Rheem Mini-Tank Water Heater can be mounted on a wall or placed on the floor. A wall bracket is included for wall mounting.

• Wall Mounting: Secure the included wall bracket to a sturdy surface using appropriate fasteners. Ensure the wall can support the weight of the unit when full (approximately 77 lbs for the 6-gallon model).
• Floor Mounting: Place the unit on a level, stable surface.

Plumbing Connections:

1. Identify the cold water inlet (marked with a blue dot) and hot water outlet (marked with a red dot) on the top of the unit.
2. Connect the cold water supply line to the inlet.
3. Connect the hot water outlet to the fixture requiring hot water.
4. Install a Temperature and Pressure (T&P) relief valve (included) into the designated port. Ensure the discharge pipe from the T&P valve is routed to an open drain.
5. Open the cold water supply valve and allow the tank to fill completely. Open a hot water faucet at the fixture to purge air from the system until a steady stream of water flows.
6. Check all connections for leaks.

Electrical Connection:

1. Ensure the power supply is off at the circuit breaker before plugging in the unit.
2. Plug the 15-amp cord into a grounded 120-volt electrical outlet.
3. Turn on the power supply at the circuit breaker.

Operating Instructions

Temperature Adjustment:

The water heater features an adjustable temperature control dial located on the front of the unit. The temperature range is from 50°F (10°C) to 140°F (60°C).

1. Ensure the unit is powered on. The "POWER" indicator light will illuminate.
2. Rotate the dial clockwise to increase the temperature and counter-clockwise to decrease it.
3. The "HEATING" indicator light will illuminate when the unit is actively heating water. It will turn off once the set temperature is reached.

WARNING:

Setting the temperature above 125°F (52°C) can cause severe burns. Exercise caution when setting higher temperatures, especially in households with children, elderly, or individuals with disabilities. Consider installing anti-scald devices at fixtures if higher temperatures are desired for other uses.

Maintenance

Regular maintenance ensures the longevity and efficient operation of your water heater. Always disconnect power to the unit before performing any maintenance.

Draining the Tank:

If the unit will be unused for an extended period or if there is a risk of freezing, the tank should be drained.

1. Turn off the electrical power to the water heater at the circuit breaker.
2. Close the cold water supply valve to the unit.
3. Open a hot water faucet at a nearby fixture to relieve pressure.
4. Carefully open the T&P relief valve or connect a hose to the drain valve (if present) and route it to a suitable drain.
5. Allow all water to drain from the tank.
6. Once drained, close the T&P valve/drain valve and the hot water faucet.

Anode Rod Inspection:

The anode rod helps protect the tank from corrosion. It should be inspected annually and replaced if significantly depleted. This procedure should be performed by a qualified technician.

Cleaning:

Wipe the exterior of the unit with a damp cloth. Do not use abrasive cleaners or solvents.
