Manufacturer's Instructions

FIGURE 24.

Please note the following:

•The system should be installed only with piping that is suitable for potable (drinkable) water such as copper, CPVC, or polybutylene. This water heater must not be installed using iron piping or PVC water piping.

•Use only pumps, valves, or fittings that are compatible with potable water.

•It is recommend that only full flow ball or gate valves are used in water piping installations. The use of valves that may cause excessive restriction to water flow is not recommended.

•Use only 95/5 tin-antimony or other equivalent solder. Any lead based solder must not be used.

•Piping that has been treated with chromates, boiler seal, or other chemicals must not be used.

•Chemicals that may contaminate the potable water supply must not be added to the piping system.

Closed System/Thermal Expansion

Pmpe_y Damage Hazard

•All water heaters eventually leak

•Do notinstallwithoutadequate drainage.

As water is heated, it expands (thermal expansion). In a closed system, the volume of water will grow. As the volume of water grows, there will be a corresponding increase in water pressure due to thermal expansion. Thermal expansion can cause premature tank failure (leakage). This type of failure is not covered under the limited warranty. Thermal expansion can also cause intermittent temperature-pressure relief valve operation: water discharged from the valve due to excessive pressure build up. The temperature-pressure relief valve is not intended for the constant relief of thermal expansion. This condition is not covered under the limited warranty.

A properly-sized thermal expansion tank should be installed on all closed systems to control the harmful effects of thermal expansion. Contact a plumbing service agency or your retail supplier regarding the installation of a thermal expansion tank.

Temperature and Pressure Relief Valve

Explosion Hazard

Temperature-pressure relief valve must comply with ANSI Z21.22-CSA 4.4 and ASME code.

• Properly sized temperature- pressure relief valve must be installed in opening provided.

• Can result in overheating and excessive tank pressure.

• Can cause serious injury or death.

153.33262, 153.33264 specifications

The Kenmore 153.33262 and 153.33264 are highly versatile and efficient portable air conditioners designed to provide optimal cooling solutions for indoor spaces. These models stand out in their class due to their advanced features, technologies, and user-friendly characteristics, making them suitable for a variety of environments, from small apartments to large rooms.

One of the primary features of both the Kenmore 153.33262 and 153.33264 is their high cooling capacity. With powerful BTUs, they can effectively cool spaces up to a specified square footage. This capability ensures that users can maintain a comfortable indoor climate even during the hottest summer months. Their energy efficiency is another notable aspect, allowing homeowners to enjoy cooler air without incurring exorbitant energy bills.

The two models are equipped with various modes of operation, including cooling, fan, and dehumidifying modes. This multifunctionality allows users to customize their comfort based on prevailing weather conditions. For instance, the dehumidifying mode effectively reduces excess moisture in the air, creating a more comfortable environment, particularly in humid regions.

Both air conditioners come with a user-friendly digital interface that features an easy-to-read LED display. The interface allows for straightforward adjustments to the temperature, fan speed, and operating modes. Furthermore, remote control functionality enhances convenience, enabling users to change settings from across the room.

In terms of technology, these models incorporate a self-evaporating system that minimizes the need for manual water drainage. This feature is particularly advantageous for users who prefer low-maintenance options. Additionally, both units feature a washable air filter, designed to capture dust and allergens, improving air quality and ensuring that the units operate efficiently.

Portability is another significant characteristic of the Kenmore 153.33262 and 153.33264. Built-in caster wheels and side handles allow for easy movement from room to room, making them ideal for temporary cooling needs. The easy installation process and included window exhaust kit mean users can set up the units quickly without requiring professional assistance.

In conclusion, the Kenmore 153.33262 and 153.33264 portable air conditioners offer a robust combination of high cooling performance, energy efficiency, and user-friendly features. Their advanced technologies and versatile functionalities make them an ideal choice for those seeking effective indoor air conditioning solutions.
