DANGER
Risk of serious injury or death due to electric shock.
If live parts are touched, there is risk of life-threatening injuries.
•
Ensure that the system is voltage-free before installing the device.
•
Ensure that the system is secured and cannot be reactivated by other
persons.
•
Ensure that installation work for the electric connection of the device is
carried out by an electrician, and in compliance with electrical
engineering regulations.
CAUTION
Risk of injury due to pressurised liquid
If installation, removal or maintenance work is not carried out correctly, there
is a risk of burns and other injuries at the connection points, if pressurised
hot water or hot steam suddenly escapes.
•
Ensure proper installation, removal or maintenance work.
•
Ensure that the system is de-pressurised before performing installation,
removal or maintenance work at the connection points.
CAUTION
Risk of burns on hot surfaces
Hot surfaces in heating systems can cause burns to the skin.
•
Wear protective gloves.
•
Please place appropriate warning signs in the vicinity of the device.
CAUTION
Risk of injury due to falls or bumps
Bruising from falls or bumps on system components during installation.
•
Wear personal protective equipment (helmet, protective clothing,
gloves, safety boots).

Note!
Confirm that installation and start-up have been carried out correctly
using the installation, start-up and maintenance certificate. This action is
a prerequisite for the making of warranty claims.
–
Have the Reflex Customer Service carry out commissioning and
the annual maintenance.
6.1.1 Incoming inspection
The device is carefully inspected and packed prior to shipping. Damages during
transport cannot be excluded.
Proceed as follows:
1. Upon receipt of the goods, check the shipment for
•
completeness and
•
possible transport damage.
2. Document any damage.
3. Contact the forwarding agent to register your complaint.

6.2 Preparatory work
Condition of the delivered device:
•
Check all screw fittings and electrical connections of the Servitec for proper
seating.
Tighten the screws and fittings as necessary.
Preparing the device installation:
•
Frost-free, well-ventilated room.
•
Ambient temperature > 0 to maximal 45 °C.
•
Level, stable flooring with a drainage facility.
•
Filling connection DN 15 to DIN 1988 -100/ -600 / DIN EN 1717.
•
Electric connection 230 V~, 50/60 Hz, 16 A with upstream ELCB: Tripping
current 0.03 A.
The Servitec can be operated in two different modes for water make-up. When
installing the Servitec, note its position within the system:
•
Pressure-dependent make-up of system water (Magcontrol).
–
Install the Servitec in the vicinity of the expansion vessel.
•
Level-dependent make-up of system water (Levelcontrol).
–
Install the Servitec on the system side in the return upstream of the
return flow admixture.

Note!
Servitec make-up line.
–
Use the Fillset system separator if the make-up line of the drinking
water mains is closed.
–
The applicable guidelines and regulations of the country of
installation must be observed.

Note!
Comply with the Reflex planning directive.
–
During planning, take into account that the working range of the
Servitec must be between the "pa" supply pressure and the "pe"
final pressure in the working range of the pressure maintenance
system.
6.3 Execution
ATTENTION
Damage due to improper installation
Additional device stresses may arise due to the connection of pipes or
system equipment.
•
Ensure that pipes are connected (torque-free) from the device to the
system without them being stressed or strained.
•
If necessary, provide support structures for the pipes or equipment.
ATTENTION
Property damage caused by leaks
Leaks in the connection pipes to the device can cause material damage to the
facility system.
• Use only connection pipes with appropriate resistance against the facility
system temperature.
In heating systems, preferably install the device in the return side.
–
In this manner, you ensure that the device is operated within the
permissible pressure and temperature ranges.
–
In systems with return admixtures or hydraulic switching points, the device
must be installed upstream of the admixture point to ensure degassing in
the "V" main flow volume at temperatures ≤ 90 °C.
The device is pre-wired and must be adapted for the local system conditions.
Complete the water-side connection to the system and the electric connection as
shown in the terminal diagram,  6.5 "Electrical connection",  33.
