INDOL EH100UV4 Heat Pump Heater

Product Information

The INDOL-UV4 system is a wall-mounted air conditioning unit designed to capture thermal energy from the air and provide cooling. It comprises several components including the INDOL-UV4 unit, silent-blocks, anchor screws, safety valve, and a user manual. The system operates based on the following principles:

1. The evaporator captures thermal energy from the air using refrigerant.
2. The compressor increases the temperature and pressure of the refrigerant.
3. The refrigerant circulates to the expansion valve, where its pressure decreases before entering the evaporator.

The unit has two air connections located at the top cover, allowing for different installation possibilities. It is recommended to install a double duct system to recover cold air and refresh a room. The electrical connection of the equipment is 230 V/1/50 Hz.

Product Usage Instructions

1. To install the INDOL-UV4 system, follow these steps:
   • Mount the unit on the wall using the supplied brackets.
   • Secure the unit using coach screws M10x80, lock washer M10, and screw anchors 12×60.
   • Adjust and regulate the supplied silent blocks on each side of the unit.
2. For air connection:
   • Use a double duct system to recover cold air and refresh a room.
   • Install one duct to the room and another to outdoors.
   • Use a gate to control the airflow, directing it outdoors when cooling isn’t needed.
   • Ensure the electrical connection of the equipment is 230 V/1/50 Hz.

TECHNICAL INFORMATION

Operating Principle

1. The evaporator captures the thermal energy from the air through the refrigerant.
2. The compressor compresses the refrigerant, increasing its temperature and pressure.
3. The collected energy is transferred to water in the condenser. The accumulated water in- increases its temperature reaching up to 55 °C.
4. The refrigerant circulates to the expansion valve, where its pressure decreases to achieve the optimum conditions before entry into the evaporator.

INSTALLATION STEPS

Before starting the installation, check the availability of all the necessary components and tools:

• Drill
• Screwdriver
• Hydraulic installation components
• Electric installation components

Once it has been checked that it is available all the necessary components and tools, the installer should follow the next steps:

1. Placing the unit
2. Hydraulic installation
3. Air connections
4. Electric installation
5. Commissioning

PLACING INDOL-UV4 UNIT

The place where the system will be installed should allow easy access to maintenance work or inspection. The air outlet of the unit is around 5-10 degrees below the inlet temperature, so in case the exhaust air is not be ducted, the room temperature will be considerably reduced. Besides these factors, it is important to consider the following indications regards the installation site:

• The system has been designed and manufactured for its indoor utilization. Install the system in a dry, frost-free room at a minimum temperature of 5 °C.
• The installer must install the supplied silent blocks to avoid the transmission of vibration.
• The wall where the system will be installed has to bear the weight of the system full of water.

WALL INSTALLATION

The device is designed for wall-mounting installation and, therefore is supplied with two brackets in the back. The installer has to fix coach screws M10x80, lock washer M10 and screw anchors 12×60. In addition, there are two holes on each side to adjust and regulate the silent blocks supplied to the wall.

AIR CONNECTION

Indol-UV4 unit has two air connections located at the top cover of the system. There are different installations possibilities:

Since the temperature of the exhaust air is lower than the intake air flow, the user can recover this cold air to refresh a room. In this case, it is recommended to install a double duct, one to the room and the other to outdoors. Using a gate, the user can stop the airflow conducting it to outdoors when cooling isn’t needed.

IMPORTANT:

• Do not use a flexible duct! Only smooth PVC pipe is allowed.
• Do not use an anti-insect grid.

When the inlet and outlet ducting is needed, use only rigid smooth PVC tubes. The pressure drop in the whole air circuit (pipes and accessories) must be lower than the static pressure of the system, 50 Pa. The following table shows the allowed total pipe length (intake + exhaust). The equivalent length of any accessory installed in the circuit must be subtracted to the maximum allowed pipe length:

SUCTION FILTER

• The system includes an air intake filter for the protection of all the elements of the refrigeration circuit.
• This filter should be checked every 6 months to verify that it has not been clogged.
• To do this, remove the filter from the suction duck and check if the channels allow air passage. Otherwise, wash it with water or replace it with a new one.
• If you notice that the system does not heat up, check the condition of the filter.
• A clogged filter affects the life-cycle performance and hot water production of the system.

Photovoltaic input

• Working in this mode, the system automatically heats the water due to electric energy surplus or by Off Peak rate.
• The parameters of this mode can only be changed by the Insta seller’s Menu. Contact the technician for more information.
• The system can be combined with and Photovoltaic Inverter to take advantage of the surplus energy generated by the panels, by forcing the system to work and storing this energy in useful hot water.
• The system has the electric boar two terminals to connect a zero-voltage contact.
• When the contact is closed, the system automatically changes to Photovoltaic mode and the heat pump and electric heater work to achieve the programmed temperature. When the contact is opened, the system returns to the previous mode.
• This contact can be also used for Off Peak Rates. To do it, connect into the contact a timer with a zero voltage output.
