The ROTEX SANICUBE hot water indirect cylinder is an entirely new product of its kind, developed on the basis of the latest priciples of water hygiene and heating technology. The tank itself is a double-skinned container made entirely of plastic. The space between the inner wall (10) and outer wall (12) is filled with high-insulating foam (11), resulting in a high level of thermal insulation and minimal surface losses The outer skin, approximately 3-4 mm thick, is impact and shock resistant and is therefore an effective protection against damage. When put into operation, the storage tank is only filled with storage water (13). The water is entirely un-pressurized and is not replaced while the tank is in use.

The stored water can be heated in a variety of ways, i.e.:

1. Via a metal-pipe heat exchanger containing heating water (3) (supplied by an oil-, gasor solid fuel fired boiler) or from other heat sources such as a solar heating system.

2. By means of an electric immersion heater

(2, 4 or 6 kW) (4).

3. By a sanitary water heat pump (8).

The sanitary water is heated in a plastic-pipe heat exchanger (9) which occupies the entire depth of the tank and is completely surrounded by the storage water. In this case, the sanitary water is not heated and stored in a largecapacity tank (as with most conventional hot water tanks), but is contained inside a pipe.

The heat is not stored in the sanitary water, but in the stored water from which it is entirely separated.

A d v a n t a g e s

The SANICUBE tank is a combination of a hot water indirect cylinder and instantaneous water heater. In this entirely new design concept lie the special advatages of the

SANICUBE tank:

Hygienically optimised water

With the SANICUBE hot water indirect cylinder, slow-flowing or inadequately heated volumes of sanitary water are avoided altogether. Deposits of sludge, rust or other sediments, which can occur in large-capacity tanks, cannot arise. In addition, the water which is stored first is also discharged first

(first-in-first-out principle). The hygienic advantages of the SANICUBE tank are considerable.

Corrosion and maintenance free

The storage tank and the sanitary water heat exchanger are made of plastic and are therefore not subject to any corrosion. No protective anode or similar corrosion inhibiting device is necessary. With the SANICUBE tank, maintenance operations, such as the replacement of protective anodes or the cleaning of the tank, are entirely unnecessary.

Minimal limescale

In the stored water compartment, it is only possible for limescale to be deposited in the initial phase of its use. As a result, the immersion tube and all of the heat exchanger pipes in the stored water remain clean. Even in the sanitary water compartment of the

PE-X-pipe heat exchanger, the normally high flow rates and smooth surface of the pipes themselves prevent the accumulation of limescale.

For hard water we recommend stopping the pressure reduction from the general supply to the house water supply ONCE a year in order to flush the tank with a higher pressure.

Economical operation

The all-round thermal insulation of the storage tank ensures minimal losses when in operation. The energy requirements for the hot water generation are therefore kept at a minimum.

The cold water connection has to be installed according to DIN 1988 (see illustration).

At a water pressure of more than 4 bars you need a pressure reducer. The operational pressure must be adjusted to max. 4 bars.

Basically, generators of sanitary water should be placed as near as possible to the bleeding points. Even when the bleeding points are not that near you can often do it without a circulation line If it is impossible to avoid a circulation line you can install it according to the illustration 1. To minimize the heat losses, all the hot water pipes must be carefully insulated.

Lime arising is flushed out with the hot water of the PE-X heat exchanger. If the water is very hard (harder then 10° dH) it is advisable to install a filter within the warm water pipe after the SANICUBE. Otherwise the lime arising can block up the percolators at the bleeding points.

When first putting into operation the following is to do:

1. Place the tank.

2. Connect the cold water supply pipe according to DIN 1988.

3. Connect the hot water supply pipe.

4. Adjust the pressure reducer to 4 bars.

5. Open the hot water bleeding points, fill the pipes and flush them.

6. Connect the metal pipe heat exchanger to the boiler.

7. When intended, install the sanitary water heat pump WP 400, (See WP 400 installation)

8. Fill the SANICUBE with cold water until the level indicator is between >Min.< and

>Max.<.

By unscrewing the thermometer plunge bush you can use the upper screwing on the side as an overflow.

9. If required connect the electric immersion heater.

To avoid a possible discharge by gravity circulation, a nonreturn valve must be installed within the loading circuit. Generally it has to be observed that the heating water temperature in loading mode is higher than the adjusted nominal temperature of the SANICUBE.

Loading regulation

Heat exchanger

SANICUBE is available in 3 versions.

All 3 types have the same metal pipe heat exchanger. For different applications we offer various heat exchangers:

If the SANICUBE is heated up with a boiler, the boiler integrated regulation, with the sanitary water priority, can be used to control the storage load pump. Therefore the sanitary water sensor is inserted (approx. 1 m) into the plunge pipe of the SANICUBE. If such a regulation does not exist, or when other heat sources e.g. solid fuel fired boiler or solar absorber are used, the loading pump can be controlled by the LR 2.

In addition to the loading possibilites with various heat sources and energy mediums the

SANICUBE can be equiped with the following accessories:

Electric immersion heaters:

EHS-500-1

EHS-500-2

230 V/2 kW

380 V/2, 4 and 6 kW

Both types have a screwing thread R 1 1 /

2

".

First of all, the immersion heater must be screwed into the thread which is placed at the centre of the tank.

The EHS-500-1 has an integrated temperature regulation and a limiter. It is ready to work on delivery.

The EHS-500-2 is delivered with a separate load regulation LR 4. This includes temperature regulation and limiter, thermometer and switch protection.

The LR 4 is fixed with the included metal angles next to the plunge pipe on top. The capillary pipe sensors are carefully inserted into the plunge pipe (approx. 1 m).

The electrical connection of the immersion heater and the regulation should be done according to the enclosed wiring scheme by an electrician. These may only be put into operation when the SANICUBE is completely installed and filled with water.

Load regulator

To control the loading of the indirect cylinder, we offer two types of regulators:

LR 2: to load by means of heating water - e.g. with a boiler or remote heat.

LR 4: to load by means of an electric immersion heater (suitable for off-peak electricity).

All the accessories can be retrofitted at any time and are optimally suitable to each other.

Operation

Within a period of several years, the level of the storage water can decline to the minimum

(level indicator). In this case, the storage water must be refilled with fresh water until the level indicator is at the maximum.
