1. GENERAL

The Husky Intelligent I16is an air source heat pump for space heating and domestic hot water heater for houses, apartment blocks and small industrial premises. Outdoor air is used as a heat source creating free energy to heat your home.

2. SYSTEM DESCRIPTION

The Intelligent I16is a monoblock (single unit) air/water heat pump, specially designed for the colder climate.

There is no need for bore holes and usually the system can be installed within 2 days.

The Intelligent I16can both heat hot water effectively at high outdoor temperatures and give a high output to the heating system at low outdoor temperatures. If the outdoor temperature drops to a level lower than minus 20c

(factory setting), the auxiliary heater switches on to ensure the heat pump unit works normally. The heat pump controller is an intelligent wired system.

The Husky Intelligent I16is rated as 16KW.The Material/components are chosen to provide a long service life and to fully withstand harsh outdoor conditions.

Intelligent I16has two different installation options:

1). Space heating + DHW (Domestic hot water)

2). Space heating or DHW

3.INSTALLATION

3.1: General points for installation engineer

3.1-1: Transport and storage

The unit should be transported and stored vertically.

Version 15 – 07/04/2016

Page 4

3.1-2: Inspection of the installation

Current regulations require the heating installation to be inspected before it is commissioned.

The inspection must be carried out by a suitably qualified person and should be documented. If the heat pump is replaced, the installation must be inspected again. In the event of installation with unvented (closed) heating systems, G3 unvented guidelines must be followed during the installation. It should be noted that the heat pump provides the first measure of defense against high pressure temperatures. A further 2 must be installed to comply with the G3 unvented procedures.

3.1-3: Siting the heat pump

The unit is placed (securely fixed) outdoors on a firm base, preferably a concrete foundation. It should not be positioned next to sensitive walls, for example, next to a bedroom. Also ensure that the placement does not inconvenience any neighbors. Local planning permission in all cases applies.

Large amounts of condensation water as well as de-icing water from defrosting can be produced. You must provide good drainage at the installation area and make sure the water cannot run out onto paths or the like during periods that ice can form. Ideally, condensation water is led off to a water drain or a suitable soak away. The unit can be sited against the wall.

3.1-4: Controller:

The Intelligent I16is equipped with an external electronic controller that handles all functions necessary for heat pump operations. Defrosting, stop at max/min temperature, connection of the compressor heater as well as enabling the auxiliary electrical heater, monitoring of motor protection and pressure switches are all controlled.

The controller is set during installation and can be used during a service.

Under normal operating conditions the home owner does not need to have access to the controller. The Intelligent

I16 has an integrated electronic outlet water temperature sensor that limits the outlet temperature to 60℃.

3.2 Installation design

The Intelligent I16can be installed in several different ways.

The heat pump is not to be used without a buffer tank or without a suitable hot water tank (designed for heat pumps).

There are not extra controls or safety devices required with each Husky heat pump unit.

Any safety equipment installed (e.g. cylinder g3 unvented) must be installed in accordance with current regulations for all installation options.

When connecting with the Intelligent I16, the total water volume in the heat pump pipe system and buffer tank must be at least 5litres per KW of output.

3.3Pipe Connection

28mm pipe is recommended.

The pipe work must be flushed before the heat pump is connected, so that any contaminants do not damage the components parts.

The heating water inlet and outlet direction must be connected according to the marked areas on the heat pump.

All outdoor pipes must be thermally insulated with at least 19 mm thick pipe insulation. The insulation must also be vapor and UV resistant.

The water circulation pump must at all times be operational (even if Intelligent I6is not running) to prevent any possible damage due to freezing. Even when in standby mode, the circulation pump is controlled directly from the

Intelligent I16, which takes the outdoor temperature and temperature in the pipe into consideration to decide whether to circulate water within the system.

Shut-off valves and drain valves are fitted so that Intelligent I16can be emptied in the event of prolonged power failures.

The supplied flexible hoses act as vibration dampeners. The flexible hoses are fitted so a slight bend is created, thus acting as vibration dampening.

Important: Even though the Intelligent I16has anti-freeze protection, if the circulation pump fails or there is a problem with the power supply, there is still a risk of damage due to freezing. During the installation Anti- freeze is recommended and can affect your warranty.

Version 15 – 07/04/2016

3.4 Electrical Connection

Electrical installation and service must be carried out under the supervision of a qualified electrician. Electrical installation and wiring must be carried out in accordance with local regulations.

3.4-1: Electric Diagram Intelligent I16

3.4-2: Circulation Pump

The integral circulation pump is controlled by the Intelligent I16. Pump activity depends on the status of heating/hot water requirements and outdoor temperature (anti-freeze function). The circulation pump can also be removed and fitted inside the building.

3.4-3:Anti-freeze Function

The heat pump protects itself, and the cylinder by maintaining a minimum temperature of 20 degrees in the cylinders and a minimum of 5 degrees in the Heat pump itself.

Version 15 – 07/04/2016

Page 8

3.4-4: Compressor Heater

The Intelligent I16is equipped with a compressor heater that heats the compressor before start-up and when the compressor is cold. The compressor heater must have been connected for 10 minutes before the FIRST start up.

The compressor heater will start automatically after turning on the heat pump and the ambient air temperature is lower than 20C.

3.5 COMMISSIONING

3.5-1: Preparations

Before commissioning, make sure the compressor heater has already pre-heated for 10 minutes.

1) Compressor Heater

As mentioned above, if the temperature is lower than 20C, it is important that the compressor heater can heat the compressor before the first start up. In order to ensure this happens, please follow the instructions below: a. Disconnect the power connection of compressor, aux electric heater, circulation pump. (Due to anti-freeze protection, the compressor, auxiliary electric heater and circulation pump could start in stand-by status. b. Switch on the outside Isolator and power connection of the unit. c. After 10 minutes, switch off the outside Isolator and re-connect the power connection of compressor, auxiliary electric heater and circulation pump.

2) Filling and Venting

Fill the system slowly ensuring bleed valves are open.

3.5-2: Inspection before Start up

1) Mechanical Inspection: a. Check the cabinet and inside pipe system for possible damage during transportation. b. Check that the heating water circuit is filled and well vented. Check the pipe system for leaks. c. Check the Fan making sure it can move freely.

2) Electric System Inspection a. Check the power supply (voltage/frequency) matches the rating label and specification. b. Check all the electrical connections for loose or damaged wires due to transportation.

3) Pipe Inspection a. Check all the valves, and water flow directions. b. Check for any possible leaks inside or outside of unit. c. Check the insulation of all the pipes.

Version 15 – 07/04/2016

7. Maintenance

7.1 Maintenance and Cleaning for User

It is good practice to inspect your heat pump regularly. Maintenance should be carried out at least annually to maintain a good lifespan of your heat pump.

1. Regularly clean the filters every 6 months to ensure that the system is clean and to avoid blockage to the system.

2. Units should be kept clean (no leaves or dirt) and no obstructions should be placed in front of or behind the unit.

Good ventilation and regular cleaning (3-6 months) of the evaporator will help maintain efficiency.

3. Ensure the unit has power in the winter whether the unit is used or not.

7.2 Maintenance for Specialist

1. Check the power unit and electrical system.

2. Check the water system, safety valves and exhaust devices are working properly so as not to pump air into the system causing reduced circulation.

3. Check water pump is functioning properly. Make sure the water pipeline and pipe fittings are not leaking.

4. Clear evaporator of any debris.

5. Check the various components of the unit work properly. Inspect the pipe joints and valves branch have inflated oil, to ensure no leakage of the refrigerant unit.

6. Chemically flush the plate heat exchanger after every 3 years.

7. Check refrigerant gas content if necessary.

8. Check delta (water in/out) making it meets the guidelines of delta 3 to 7.

8. How to Get the Most Out Of Your Heat Pump

It is important to understand that you should operate heat pumps differently to conventional heating systems such as gas boilers. Below are some points you should be aware of:

 Since heat pumps produce water at a lower temperature (than gas boilers), it is important to remember the heat up time of your property is slower.

 The lower temperature the heat pump produces, the more efficient it is.

 The higher the ambient temperature (outside temperature), the more efficient the heat pump is.

 The heat pump has a simple job, and that is to maintain the water tanks at the set temperature.

 It’s a good idea to let your heat pump maintain your water tank temperatures 24 hours a day during the winter.

This will enable your central heating controller to call for heat in the home at any time. During the summer you can set the timer on the heat pump controller for your hot water requirements.

With the above in mind, you could decide between the following:

Option 1. You could decide to operate your heat pump during the day time (when temperatures are higher). At the same time you could set the water temperature lower. This will basically charge your home during the day so in the evening the home is warm and the heat pump simply maintains the heat. This is not controlled by the heat pump controller, it is controlled by your central heating controller.

Option 2. You could operate your central heating controller in a similar way to a conventional boiler. You must set the programme at least 1 hour before you need your property to be warm. The downside to this is that you may need to set the water that the heat pump produces to a higher temperature.

Option 3. You could decide to operate your home with back ground heat. This means you are always (24 hours a day) putting a trickle heat in your home

In all cases it is recommended to maintain a minimum temperature in your home (e.g. 14c to16C) during the evening. This is controlled by your central heating controller.
