One of the most important parameters This series of air handling units with heat recovery is its high energy efficiency due to the transfer of thermal energy from the removed warm air supply cold.

The efficiency of modern membrane recuperators used in these installations reaches 70%.

The use of Electrolux EPVS-1100 air handling units with heat recovery is especially relevant for our climate, when winter period The year lasts 7-8 months a year.

According to the experience of our research and calculations, the payback for air handling units with recovery occurs on average in 1.5-2 years of operation. Compared to equipment that heats supply air electricity.

High recovery efficiency is achieved through modern technology using a membrane-type heat exchanger-recuperator with the ability to transfer part of the heat with moisture through the surface of the recuperator.

However, recovery alone is not enough for full heating, so it is necessary to install an auxiliary heater, although its power is already significantly less than what would be needed to heat the same volume of air without using recovery.

Control

Control of this equipment model is absolutely simple. Enabling/disabling and adjusting the necessary parameters is carried out using the control panel:

Advantages and disadvantages of this model of air handling unit

Recommendations for selecting an air handling unit:

It should be noted that this method selection is very indicative and suitable for designing complex ventilation systems.

Aerodynamic characteristics of the installationElectroluxEPVS-1100

If it is necessary to use a longer network of air ducts and there will be high losses, the manufacturer recommends using special booster fans:

They improve plant performance at high pressure losses.

The characteristics show how performance changes with and without the use of booster fans.

More detailed information about Electrolux EPVS-1100 installations is provided by the manufacturer in the installation and operating instructions.

Maintenance and care:

For standard operating conditions (no serious air pollution environment and normal indoor climate), it is recommended to clean or replace filters at least once every 12 months. It is advisable to carry out these procedures once every 3-4 months.

Our specialists will be happy to advise you and select the installation of the required power. Prices for Electrolux STAR PVU depend on their technical characteristics.

Buy household appliances- half the battle. It is important to know how to perform installation correctly. If you want to save on the services of a specialist, we will tell you how the installation goes dishwasher Electrolux. You will learn the details of doing the work yourself, which you will not find in the instructions.

First, decide on the size of the dishwasher. If you have a small family, then feel free to choose a compact option for 6-8 sets of dishes. When integrating the Electrolux PMM into a finished set, it is important to choose the right place:

1. Compact model. Fits perfectly under the sink, just needs to be installed special siphon. Proximity to communications is a big plus. The machine can also be placed on a countertop, because its dimensions are no larger than a microwave oven.
2. Built-in narrow PMM. Fits in one of the closets kitchen set. It is advisable to choose a place to the right or left of the sink. If you buy equipment and order new kitchen, then a cabinet for a dishwasher is provided in advance.
3. Freestanding model. Place it in a convenient place. You can move the cabinets apart and install equipment or put it in a free corner.

It is important to place the Electrolux brand dishwasher level. The tilt to one side should not exceed two degrees.

You can remodel the cabinet in the suite yourself. To do this, remove the door from its hinges, remove all shelves and the back panel. Or make holes for hoses in the side wall.

How to avoid losing your warranty

Please read the instructions carefully before installing the machine yourself. Each manufacturer indicates acceptable standards when connecting equipment. Most dishwashers are not allowed to be connected to hot water. This leads to damage to hoses and filters.

If the PMM breaks down due to connection to a hot water supply, then warranty repair you can't count on it.

Another dangerous point is the connection to the electrical network. It is prohibited to connect powerful equipment to regular old outlets without a voltage stabilizer, or to connect it to the same outlet as an electric stove.

Wiring

If your network is not prepared, call a specialist; you should not deal with electricity yourself. What work is ahead:

1. Wall chipping. A puncher prepares a groove into which a three-core copper wire is laid.
2. Installation of a European socket. Since the PMM cord is quite short, it is recommended to place the socket at a level of 45 cm from the floor. It must be moisture resistant and grounded.
3. Connecting a 16A power breaker. It ensures stable operation of the equipment.

Connecting and placing the dishwasher

Before starting work, prepare the components:

• Siphon with two or three drainage outlets. Additional fittings are useful for connecting other devices. If not needed, one fitting can be closed with a plug.
• Tee made of brass, bronze or metal-plastic. ¾ inch thread. If the tee does not have a shut-off valve, then purchase one separately.
• Filter. Installed to purify water from impurities.
• Hoses of the required length, if standard ones are not enough.
• Fumku. High-quality fum tape waterproofs connections.

Tools you need are an adjustable wrench, pliers, and a screwdriver.

Act in correct sequence. First you need to connect the drain, then the water supply and power supply. Judge for yourself what is more convenient for you: connect all the outputs at once and install the dishwasher in the cabinet, or place it in place and then start connecting.

Working with drain

Secure drain hose at the outlet of the siphon. It should bend at the top so that waste water does not enter the PMM bunker. The bottom bend (which comes from the machine) should be short and deep.

Water connection

Have you already decided which water supply to connect to? About connecting to hot water read our article. First of all, close shut-off valve. Remove from water supply outlet kitchen faucet and old insulation. Install the brass tee. Connect a mixer, a coarse filter, and a dishwasher hose to the outputs (you can use a connecting tube - a hose). All connections are carefully insulated with fum-leta (wrap at least 10 times along the thread).

Additionally, install a ball valve if it is not on the tee.

All that remains is to plug the plug into the socket. Now you can perform a test run and check the dishwasher in action. Open stopcock and make a test run of the PMM without dishes. Make sure there are no leaks anywhere.

It is not difficult to connect the Electrolux dishwasher with your own hands. The main thing is to act consistently and follow the instructions. A video on the topic will help you:
