12 SYSHRW 10. INSTALLATION Caution The unit is not designed to withstand weights or stresses from adjacent equipment, pipe work or constructions. Any foreign weight or stress on the unit structure could lead to a malfunction or damage, which could prove hazardous to personnel and property. In such an event, the warranty shall be voided.
SYSHRW 10.3. UNIT LOCATION Caution The unit base shall be arranged as indicated in the manual. There could be a risk of personal injury or damage to property in the event of the unit being incorrectly supported. 1. The installer must ensure that access under the suspended ceiling is provided, and that sufficient space is provided for the suspension angle brackets, the duct attachment collars and the water and electrical connections.
14 SYSHRW 11. DUCTING AND NOISE LEVEL REDUCTION Water circuit heat pumps are usually installed in conjunction with an air blowing duct. A return air duct may also be required. All ductwork shall be compliant with best air conditioning engineering practices. The air blowing duct system normally consists of a flexible connector mounted on the unit, a bridging section to link to the size of the main duct, a short section of straight duct, an elbow without a damper and a main duct with spurs equipped with distribution grilles as illustrated in the drawing below.

16 SYSHRW 11.2. FILTER ACCESS Each unit is supplied with a connection frame also serving as the filter support. This enables to filter to be removed from the side without having to dismantle the duct or the connection frame. 11.3. VENTILATION An outdoor air intake (new air) may be required for ventilation.
18 SYSHRW 12. HYDRAULIC LINKS Caution THE WARRANTY DOES NOT COVER DAMAGE DUE TO CORROSION RESULTING FROM ELECTROLYTIC PHENOMENA. 12.1. WATER QUALITY The water must be analyzed; the hydraulic network system installed must include all elements necessary for water treatment: filters, additives, intermediate exchangers, drain valves, vents, check valves, etc., according to the results of the analysis.
SYSHRW 12.2. RECOMMENDATIONS FOR HYDRAULIC CONNECTIONS 1. It is recommended that all units are connected to a water supply and return pipe system of the Tickelman Loop type. The Tickelman Loop system is self-balancing and thus only requires manual balancing if a large number of units with different flow and pressure loss characteristics are connected to a single hydraulic loop.

20 SYSHRW 6. Certain flexible hose threaded connectors are supplied with sealing paste. If this is not the case, use Teflon tape to create a tight seal. 7. Each unit must be equipped with isolation valves on the water inlet and outlet pipes. The return isolation valve is used for both cutting off the water supply and balancing the installation’s water flow.
SYSHRW 12.3. RECOMMENDATIONS FOR CLEANING AND FLUSHING OUT THE SYSTEM 1. Before commissioning an appliance for the first time, the water loop must be cleaned and rinsed out to remove any dirt and manufacturing debris. If the appliances are equipped with isolation valves (either electric or pressostatic), the water supply and return conveyance circuits to and from INTERCONNECTED CONVEYANCES each machine must be connected to each other.

SYSHRW 18.1.5. AIR FILTER In order for the installation to operate correctly, it is essential to regularly clean the air filter located in the intake of the indoor unit. When clogged, the filter reduces the air flow through the heat exchanger of the indoor unit, which in turn reduces the efficiency of the installation and inhibits the cooling of the fan motor.
34 SYSHRW 18.2. FAULT FINDING 18.2.1. NEITHER THE FAN NOR THE COMPRESSOR OPERATE 1. The system is in alarm mode when the mains power supply is switched on. Check the points mentioned in § ALARM CODES, page 35 for diagnosis. 2.
SYSHRW 18.2.6. APPEARANCE OF ABNORMAL NOISES AND VIBRATIONS IN THE CASING 1. Check that the turbine is not rubbing against the scroll and that the latter is not damaged. Replace as required. 2. Check that the turbine has not worked loose on its shaft. Centre the turbine and tighten it as required.
36 SYSHRW 19. WARRANTY CLAIM - MATERIAL RETURN PROCEDURE Equipment must not be returned without the permission of our After Sales Department.
