CALEFFI SATK Serie Instrucciones De Instalación Y Mantenimiento página 3

Installation
The SATK series HIU is designed for installation in a sheltered
domestic environment (or similar), therefore cannot be installed or
used outdoors, i.e. in areas directly exposed to atmospheric agents.
Outdoor installation may cause malfunctioning and hazards.
If the device is enclosed inside or between cabinets, sufficient
space must be provided for routine maintenance procedures. It is
recommended that electrical devices are NOT placed underneath the
HIU, as they may be damaged in the event of leaks occurring at the
hydraulic fittings.
If this advice is not respected, the manufacturer cannot be held
responsible for any resulting damage. In the event of a malfunction,
fault or incorrect operation, the device should be deactivated; contact
a qualified technician for assistance.
Preparation
After establishing the device installation point proceed as follows:
• Mark the holes required for securing the HIU to the wall;
• mark the position of the hydraulic connections.
Check the measurements again and begin laying the following
pipelines:
1. Connection to the centralized line;
2. heating circuit;
3. domestic water circuit.
N.B.: the wall anchors can only guarantee effective support if inserted
correctly (in accordance with good technical practice) into walls
built using solid or semi-solid bricks. If working with walls built using
perforated bricks or blocks, mobile dividing panels or any masonry
walls other than those indicated, a preliminary static test must be
carried out on the support system.
Hydraulic connections
Hydraulic connections to the centralized line must be implemented
using shut-off valves, which allow any necessary maintenance work to
take place without having to empty the centralized system.
It is advisable to also install manual shut-off valves on the lower
terminals for connection to the apartment heating system.
Heat meter installation (only for SATK1532. ABC)
- Close the shut-off valves;
- empty the HIU using the cocks provided;
- remove the heat meter template;
- place the volumetric meter respecting the flow direction;
- place the supply temperature probe on its proper port (located
on the DPCV body).
SAFETY INSTRUCTIONS
WARNINGS
These instructions must be read and understood before installing and maintaining the device. The symbol means:
CAUTION! FAILURE TO FOLLOW THESE INSTRUCTIONS COULD RESULT IN A SAFETY HAZARD!
CAUTION! THE PRODUCT SUPPLIED WITH THIS INSTRUCTION SHEET IS REFERRED TO BELOW AS "DEVICE"
1. The device must be installed, pre-run checked and maintained by qualified technical personnel in accordance with national regulations and/or relevant local requirements;
2. if the device is not installed, pre-run checked and maintained correctly in accordance with the instructions provided in this manual, it may not work properly and
may endanger the user;
3. clean the pipes of any particles, rust, incrustations, limescale, welding slag and any other contaminants. The hydraulic circuit must be clean;
4. make sure that all connection fittings are watertight;
5. when connecting water pipes, make sure that threaded connections are not mechanically overstressed. With time this may result in breakage with water leakage,
causing damage and/or personal injury;
6. water temperatures higher than 50 °C may cause severe burns. When installing, pre-run checking and servicing the device, take the necessary precautions so that
these temperatures will not be hazardous for people;
7. in the case of particularly hard or impure water, there must be suitable provision for filtering and treating the water before it enters the device, in accordance with
current legislation. Otherwise the device may be damaged and will not work properly;
8. any use of the device other than its intended use is prohibited;
9. any coupling of the device with other system components must be made while taking the operational characteristics of both units into consideration. An incorrect
coupling could compromise the operation of the device and/or system.
LEAVE THIS MANUAL AS A REFERENCE GUIDE FOR THE USER. DISPOSE OF THE PRODUCT IN COMPLIANCE WITH CURRENT LEGISLATION.

Initial Operation
Filling the central heating system
Open the shut-off valves on the connections to the centralized line
and, in the central heating system, proceed with charging the system
to the design pressure.
Once these procedures are complete, vent the system and check its
pressure again (repeat the filling process if necessary).
Setting domestic hot water temperature according to primary
flow temperature.
Open the domestic hot water taps, while the central heating system
is working, and set the required temperature turning the black
handle (A).

Maintenance
All maintenance procedures should be carried out by an authorized
technician. Regular maintenance guarantees better efficiency and
helps to save energy.
Before carrying out any maintenance, repair or part replacement work,
proceed as follows:
- Close the shut-off valves;
- empty the HIU using the cocks provided.
DCW strainer cleaning
- Unscrew the domestic cold water connection to have access
to the strainer;
- remove the strainer and clean it with water;
- place the strainer black in his position.
Exchanger replacement
- Remove the exchanger using the 2 hex head screws fixing it in
place (B);
- replace the exchanger, fitting new O-Rings;
- tighten the two fixing screws (B).
