Installation and connection of the instantaneous water heater: stages, wiring diagram

Water heater - appliance needed in suburban homes, where there is no central water supply, as well as useful for use in apartments with short-term stopping of hot water due to maintenance work or accidents.

The following are aspects of the installation and connection of the flow heaters to the water system.

Apparatus instantaneous water heater

Before the connection, it is necessary to introduce the device and the operating principle of the device.

There are several options for device instantaneous water heaters, differs slightly for installation nuances that affect performance. Principle of operation at the same time remains the same - cold water from the system to the input the device passes through the heating element reaches a predetermined temperature and supplied to the exit.

In this heater control system includes heating only during the passage of the liquid, and also controls the heating intensity depending on the set mode by the user.

As the heating element can act directly heating elements or special metallic tube made of brass or copper, which are heated by heating elements.

The materials that will be needed for installation

For fast and efficient installation of the unit you will need a specific list of tools and materials. There are two options for connecting storage water heaters - and temporary capital.

For temporary installation, in addition to the device itself, you need:

• hammer and drill with tip pobeditovym - for mounting a brick or concrete wall (in the case of mounting wooden support - a drill and an appropriate drill);
• level for horizontal suspension;
• wrenches;
• pliers;
• set of screwdrivers, including a display;
• water hose;
• copper electric cable, the corresponding section;
• Set for fixing (usually included with the instrument);
• dowels, screws;
• seal for hose connections: tow with Unipac type or paste fumlenta.

If you intend to carry out major installation is additionally required to prepare:

• a sanitary fittings for tapping into the line - at least tee for supplying water to the device;
• ball valve;
• Flexible hose with cap nuts to connect the device to the system.

preliminary work

Positioning the heater

Before you begin installation, you must carefully consider the place of installation. If you purchased the unit depressurized, it should be installed in close proximity to the consumer (directly in the bathroom or in the kitchen). Typically, it is used for heating the water in the shower or sink.

ATTENTION! When planning the installation of a flow heater in the shower, you must choose a place protected from the spray. Typically, the device trying to mount above the shower head, beyond the plane of dispersion of the water jets.

In spite of the protection class IP24, it is not recommended to install the unit in place of a direct hit, or fluid accumulation.

Wiring diagram for the water heater

After selecting the place of installation is necessary to ensure elektropodgotovku. In the case of switching device working on line 220 is supplied trohzhilny cable which side flap is connected to the protective grounding device. Connection of other consumers to this power is not desirable.

In the case of fixed mounting pressure model is advisable to choose the installation location near the cold water riser. As part of the preparatory measures, in addition to electricity liner, you must make changes to the water system:

• connected to the pipe through the cold water supply tee fittings segment to place the instrument installation;
• set the shut-off valve (valve) at the site;
• It recommended before feeding water to the input device to deliver a fine filter;
• pull the pipe from the output device to the hot line, connecting it as through a tee.

In such a scheme, in the absence of hot water in the line, it is necessary to block the inlet valve, wherein the valve opening towards the cold water supply to the flow heater. When you see - you must follow the steps in reverse order: block heater valve, and then open the valve on the pipeline.After summing up the electricity and water can proceed to the main assembly.

IMPORTANT! Before starting the installation work, check that the selected section of the wall, which will be attached to the device has sufficient load-bearing capacity. It is not recommended to install even the smallest devices on the walls made of drywall or plywood.

Installation of the water heater and connect to the network

the sequence of steps by commissioning a backup water supply system using the flow heater as follows:

1. Perform layout for attaching the unit to the wall. The device must be fixed horizontally, use level.
2. Punch holes using a drill or puncher. Put them in the appropriate diameter dowels.
3. Lean the heater body to the point of attachment. Fix it with a screwdriver or screwdriver.
4. Alternately connect the device to the branch pipes of hot and cold water. Do not forget to use gaskets and sealing materials where necessary.
5. And opening the feed valve includes a hot water at one of the consumer device to perform the strait purging of it.
6. Pressurize the system, turn off the tap on the part of consumers, make sure there are no leaks at the connections of the device to water.
7. Verify that the connection to the network cable is disconnected. Plug all three cores to the terminals according to their marking: N - zero, L - phase, ┴ - the earth.
8. Turn on the machine in the cluster. Check the operation of the device.
9. If the heater is working properly, complete the installation by securing the housing cover by means of screws or clamps.

ATTENTION! Never use the device in the network with absent or poor quality ground and bypassing the RCD. If the inside of the unit for any reason, there will be a leak, immediately triggered electrical protection, and potentially dangerous circuit is de-energized.

accident prevention

The combination of water and electricity, especially in open systems always keeps a hidden threat. When you install the instantaneous water heater all safety regulations must be observed, previously carefully read the installation instructions and operating instructions supplied with instrument.

It is necessary to ensure the safety of electrical wiring, a sufficient amount of allocated power for the connection device, suitable nominal breaker and RCD. If the wiring or elements of panel equipment very hot, it is impossible to use the device.

To avoid output equipment failure, need time to change the filter at the inlet to the heater and ensure there are no leaks.

In accordance with the regulations to carry out preventive work, in continuous use from time to time visual monitoring.
