SAFETY PRECAUTION
Carefully follow the precautions listed below because they are essential to guarantee the safety of Iglu Tech product.
Always disconnect the power supply of the Air-Water Heat Pump before servicing it or accessing components inside the
unit.
WARNING
•Verify that installation and testing operations shall be performed by qualified personnel.
•To prevent severe damage tothe system and injuriesto users, precautionsand other notices shall
be observed.
Carefully read the content of this manual before installing the air-to-water heat pump and store the manual in
a safe place to be able to use it as a reference after installation.
•For maximum safety, installers should always carefully read the following warnings.
•Store the operation and installation manual in a safelocation and remember to hand it over to the newowner
if the Air to Water Heat pump is sold or transferred.
•Store the user and installation manual in a safe location and remember to hand it over to the new owner if
the air to water heat pump is sold or transferred.
•This manual explains how to install an Air-Water Heat Pump. The use of other types of units with different
control systems may damage the units and invalidate the warranty. The manufacturer shall not be responsible
for damages arising from the use of non-compliant units.
•The manufacturer shall not be responsible for damage originating from unauthorized changes or the
improper connection of electric and hydraulic lines. Failure to comply with these instructions or to comply with
the requirements outlined in the “Operating limits” table, included in the manual, shall immediately invalidate
the warranty.
•Failure to comply with these instructions or to comply with the requirement on the Operating Range (Heat: -
25~35 °C/ Cool: 10~46 °C) outlined in the Product Specification hall immediately invalidate the warranty.
•Do not use the units if you see some damage on the units and recognize something bad such as loud noise,
or smell of burning.
•To prevent electric shocks, fires, or injuries, always stop the unit, and disable the protection switch and
contact.
•IGLU TECH’s technical support if the unit produces smoke if the power cable is hot or damaged or if the unit
is very noisy.
•Always rememberto inspect the unit, electric connections, refrigerant tubes, and protections regularly. These
operations shall be performed by qualified personnel only.
•The unit contains moving parts and electrical parts, which should always be kept out of the reach of children.
•Do not attempt to repair, move, alter, or reinstall the unit by unauthorized personnel, these operations may
cause product damage, electric shocks, and fires.
•Do not place containers with liquids or other objects on the unit. All the materials used for the
manufacture and packaging of the air to water heat pump are recyclable.
•The packing material and exhaust batteries of the remote controller(optional) must be disposed of by local
regulations.
The air-to-water heat pump contains a refrigerant that must be disposed of as special waste. At the end of its
life cycle, the heat pump must be disposed of in authorized centers or returned to the retailer so that it can be
disposed of correctly and safely.
•Wear protective gloves to unpack, move, install, and service the unit to avoid your hands being injured by
the edge of the parts.
•Do not touch the internal parts (water pipes, refrigerantpipes, heat exchangers, etc.) while running the units.
And if you need to adjust and touch the units, have enough timefor the unit to be cooled, and be sure to wear
protective gloves.
•In case of refrigerant leakage, try to avoid getting in contact with the refrigerant because this could result in
severe wounds.
•When you install the Air to water heat pump in a small room, youmust consider proper ventilation to prevent
a leakage level within the maximum permissible limit.
•In that case, you may die from suffocation by some possibility.
•Make sure to safely dispose of packing materials. Packing materials, such as nails and other metal or
wooden pallets may cause children to get injured.

•Inspect the product shipped and check if damaged during transport. If the product has some damage, DO
NOT INSTALL, and immediately discuss the damages with the carrier or retailer (if the installer or the
authorized technician has collected the material from the retailer.)
•Our units shall be installed in compliance with the spaces described in the installation manual, to ensure
accessibility from both sides and allow repairs or maintenance operations to be carried out. If the units are
installed without complying with the procedures described in the manual, additional expenses can be asked
because special harnesses, ladders, scaffolding, or any other elevation system for repair service will NOT be
considered part of the warranty and will be charged to the end customer.
•Always make sure that the power supply is compliant with local safety standards.
•Verify that thevoltage and frequency of the power supply comply with the specificationsand that input power
is sufficient to ensure the operation of any other domestic appliance connected to the same electric lines.
Always verify that the cut-off and protection switches are suitably selected.
•Always verify that electric connections (cable entry, a section of leads, protections…) are compliant with the
electric specifications and with the instructions provided in the wiring scheme. Always verifythat all connections
comply with the standards applicable to the installation of air to water heat pumps. Devices disconnected from
the power supply should be completely disconnected in the condition of the overvoltage category.
•Do not connect the earth wire to the gas pipe or water pipe, lightning rod, surge absorber, or telephone earth
wire. If earthing is not complete, it may cause an electric shock or fire.
•Be sure to install both an earth leakage detector and circuit breaker with specified capacity by relevant local
and national regulations.
•If it is not installed properly, it may cause electric shocks and fire.
•Make sure that the condensed water runs well out of the unit at low ambient temperature. Drainpipe and
Cond heater can frost/ice cannot grow. If drain work is not effective for releasing condensed water, it can make
the units get damaged by massive ice and the system can be stopped, covered by ice.
•Install the power cable and communication cable of the indoor and outdoor unit at least 1 m away from the
electric appliance. Protect the unit from rats or small animals. If an animal contacts the electric parts, it can
cause malfunctions, smoke, or fire. Please instruct the customer to keep the area around the unit clean.
•Do not disassemble and alter the heater at your discretion.
•Wear protective equipment (such as safety gloves, goggles, and headgear) during installation and
maintenance works.
•Installation/repair technicians may be injured if protective equipment is not properly equipped.
•This appliance is not intended for use by persons (including children) with reduced physical, sensory, or
mental capabilities, or lack of experience and knowledge unless they have been given supervision or instruction
concerning the use of the appliance by a person responsible for their safety. Children should be supervised to
ensure that they do not play with the appliance.
•For use in Europe: This appliance can be used by children aged 8 years and above and persons with
reduced physical, sensory, or mental capabilities or lack of experience and knowledge if they have been given
supervision or instruction concerning the use of the appliance in a safe way and understand the hazards
involved. Children shall not play with the appliance. Cleaning and user maintenance shall not be done by
children without supervision.
•Be sure not to perform power cable modification, extension wiring, and multiple wire connection.
It may cause electric shock or fire due to poor connection, poor insulation, or current limit override.
•When extension wiring is required due to power line damage, refer to "How to connect your extended power
cables" in the installation manual.
•Do not use means to accelerate the defrost operation or to clean, other than those recommended by Iglu
Tech.
