Connection of the solar system to a

new or existing lightning protection or

the provision of local grounding should

only be carried out by a licensed

professional, who must take into

account the prevailing conditions on

site.

HApplicability

Vitosol solar collectors are designed

for use in closed loop heating systems

for domestic hot water heating, space

heating and pool heating via a heat

exchanger. The use of Viessmann

heat transfer medium “Tyfocor-HTL”

is strongly recommended.

Other heat transfer fluids may be

suitable if they have the same

temperature range (-35°C to 170°C)

and are non-toxic.

Pool water or potable water cannot be

pumped directly through the Vitosol

collectors. Damage to collectors caused

by corrosion or scaling will void

warranty.

5285 771 v1.1

Observe maximum load and distance

from edge before installing the

substructure to the roof. If necessary,

consult with a structural engineer to

determine if the structure is suitable

for installing solar collectors. The

collectors must be securely mounted

so that the mountings can withstand

intense wind conditions and local

snow loads.

CAUTION

Gloves and eye protection must be

worn when handling solar panels.

CAUTION

Solar panel connection pipes and

solar heating fluid can become hot

enough to cause severe burns.

Extreme caution must be taken if

panels have been in a stagnant

condition (no flow of fluid).

CAUTION

Avoid scratching or sudden shocks to

glass cover of the solar panel.

CAUTION

Never step on collectors or solder in

close proximity to the glass surface

of the solar panel.

Start-up, Inspection and Maintenance

Procedure

1. Flush, leak test and fill solar heating system

Service

Start-up

All work on the solar circuit or the components of the solar heating system may only be carried out if the sky is very

cloudy, early in the morning, in the evening or with covered collectors.

We recommend the system is only flushed with the specified heat transfer medium to prevent a mixing with residual

water inside the system. Mixing would alter the level of frost protection.

HHeat transfer media containing glycol

can be damaged if they are subjected

to temperatures above 170°F / 77°C

for a prolonged period of time

(stagnation).

This can lead to the system suffering

from sludge and hard deposits,

particularly in conjunction with other

contaminants.

HEnsure that the system is correctly

flushed, filled and vented after

installation. After filling the system

with heat transfer medium, ensure the

system is correctly vented and that

heat is transferred inside the system,

i.e. that longer periods of stagnation

are avoided.

HThe blow-off and drain pipes should

terminate in an open container

capable of holding the maximum

possible collector fluid volume.

1. Cover up collectors, if necessary.

2. Manually open any installed isolation

valves.

3. Open the flow check valves on Solar

Divicon on the supply and return lines

by:

HTurning the thermometers counter

clockwise 45°.

4. Close the shut-off valve on the

system fill manifold Iandopenthe

drain valve .

5. The system is flushed via the return

line to the collector.

Fill and flush the system with heat

transfer medium via the filling valve

Flush using a quick-running pump

until you can be sure that all air has

been purged from the solar panel

system. Proper start-up can only be

guaranteed with a system that is

completely free of air.

6. Close the drain valve on the

system fill manifold. Continue to

charge system until desired cold fill

pressure is achieved, then close .

Open the shut-off valve and

check the system for leaks.

Observe the permissible operating

pressure. The pressure should not

drop over the space of at least one

hour.

5285 771 v1.1

Never mix Tyfocor HTL with alternative

heat transfer media or with water.

CAUTION

Never flush with water when it is

freezing, if no heat transfer medium is

used.

CAUTION

Never drain the system with a vacuum

pump.

Service

Maintenance

The collectors must be covered before

any work on the components of the

solar heating system begins, in order to

prevent equipment damage.

Isolate the main power supply of the

system (e.g. by unplugging the control

system or by means of a main power

disconnect switch) and safeguard

against unauthorized and/or accidental

reactivation.

3. Clean collectors

Service

Maintenance

In areas experiencing frequent rain,

collector cleaning is not usually

required. In areas with very dry

climates, urban areas or dusty areas,

check and clean collectors periodically.

Use a soap and water solution and flush

thoroughly with water.

4. Check gaskets and sealed unions

Inspection and Maintenance

Replace all worn/faulty parts.

5. Check the thermal pipework insulation

Service

Inspection and Maintenance

Check the thermal insulation of the

pipework for damage and fit. No bare

metal or fiberglass insulation should be

exposed. Adjust if necessary.

Replace all worn/faulty parts.

The thermal insulation*1 of external

pipework must be resistant to

temperature, water and UV radiation. It

must be protected against destruction

by vermin and birds (e.g. metal casing).

1. Drain the system until the pressure

gage indicates 0, or isolate the

expansion tank from the system and

reduce the pressure at the expansion

tank connection.

2. If the air cushion charge pressure of

the diaphragm expansion tank is

lower than the set system fluid

pressure value, top up with sufficient

nitrogen to raise the charge pressure

to match the set fluid pressure.

Set air cushion charge pressure of

the expansion tank using this

formula:

22 psig+0.45xstatic head in ft

(1.5bar+0.1xstatic head in m)

Static head (collector top edge to the

expansion tank) = ft / m
