WARNING

Precautions for safety

 General safety precautions

Ensure that all Local, National and International regulations are satisfied.

• Read the “Precautions for safety” carefully before installation.

• The precautions described below include the important items regarding safety – Observe them without fail.

• After the installation work has been completed, perform a test run to check for any problems. Follow the Owner’s Manual to explain how to use and maintain the unit to the customer.

• Turn off the main power supply switch (or breaker) before unit maintenance.

• Ask the customer to keep the Installation Manual along with the Owner’s Manual.

 Refrigerant precautions

• If a refrigerant leak is suspected contact the dealer who supplied the system, in the case of a recharge of refrigerant ask service personnel for details of the leak and confirmation of the repairs completed. The refrigerant used in the system is harmless.

• Generally the refrigerant does not leak, however, if the refrigerant should leak into a room and a heater or stove burner in the room is lit, toxic gas may be generated.

• Do not install the system in a location subject to a risk of exposure to a combustible gas. If a combustible gas leaks and stays around the unit a fire may occur.

• Install the refrigerant pipe securely during installation and before operation. If the compressor is operated with no pipe work connected and valves open the compressor will suck air which would result in over pressurization of the system which may result in bursting or injury. Observe the same precautions for refrigerant recovery work (pump back procedure to outdoor unit) and do not disconnect pipe work until refrigerant is recovered and valves closed.

Installation precautions

• Ask an authorized dealer or qualified installation professional to install/maintain the Air to Water Heat Pump System. Inappropriate installation may result in water leaks, electric shock or fire.

• Electrical work must be performed by a qualified electrician in accordance with the installation manual. An inappropriate power supply capacity or installation may result in fire.

• When completing any electrical works to the system ensure that all Local, National and International regulations are satisfied. Inappropriate grounding may result in electric shock.

• Ensure all electrical cables, used for the Hydro Unit installation, comply with all Local and National regulations. Check all electrical terminations are secure and tight.

• Earth wire connections.

• Install an earth leakage breaker without fail. Incomplete grounding can cause electric shock. Do not earth wires to gas pipes, water pipes, lightning rods or telephone cable earth wires.

5-EN

Hydro Unit Installation Manual

• This unit must be connected to the main power supply using a circuit breaker or switch with a contact separation of at least 3 mm.

• Be sure to turn off all main power supply switches or the circuit breaker before starting any electrical work. Ensure all power switches are off, failure to do so can cause electric shock. Use an exclusive power circuit for the Air to Water Heat Pump system using the rated voltage.

• Ensure correct connection of interconnecting wire between Outdoor Unit and Hydro Unit. Incorrect connection of the interconnecting cable may result in the damage of electrical parts.

• Under no circumstances must not power cable be extended. Connection trouble in the place where the cable may give rise to smoking and / or a fire.

• Ensure refrigeration system remains sealed to external gases and air. Should air or other gases contaminate the refrigeration circuit, high system pressures could result in burst pipes and injuries.

• Do not modify or bypass any of safety guards or switches in this system.

• After unpacking the outdoor unit, examine the unit carefully for any possible damage.

• Do not install in any place that might increase the vibration of the unit.

• To avoid personal injury (with sharp edges), be careful when handling parts.

• Perform installation work properly in accordance with the installation manual. Inappropriate installation may result in water leaks, electric shock or fire.

• Tighten all flare nuts with a torque wrench in the specified manner. Excessive tightening of the flare nut may result in cracking of the pipe work or flare nut which may result in a refrigerant leakage.

• Wear heavy duty gloves during installation work to avoid injury.

• Install the outdoor unit securely in a location where the base can sustain the weight adequately.

• In enclosed areas, if the refrigerant leaks during installation vacate and ventilate immediately.

• After installation is complete ensure and confirm that refrigerant does not leak. If refrigerant leaks into a room and flows near a fire source noxious gas may be generated.

• Do not block any drain hoses. Hoses may come off and electric shocks may occur.

• Do not hit the manometer, because it is made of glass. It is breakable.

Hydro Unit Installation Manual

 Notes on system design

• The inlet water temperature to the Hydro Unit must be 60 °C or less. Especially, be careful when there is an external heating source such as a boiler. When hot water over 60 °C returns, it may result in a failure of the unit or water leakage.

• The flow rate of the circulating water must meet the following range. 11 kW 18 L/minute or more 8 kW 13 L/minute or more If the flow rate becomes less than the minimum, the protective device is activated to stop the operation. To ensure the minimum flow rate of the water system, install a bypass valve on one water circuit. Please note this circuit must contain a minimum of 20 liters. If total water amount is not enough, the unit may not function fully due to protective operation.

• Do not drive water by power other than the pump built in the Hydro Unit.

• The back up heaters, in the hydro unit, are designed to assist the heat pump during periods of low ambient conditions.

• Ensure the Hydro unit and the connecting water pipes are installed in a location that is not exposed to low ambient temperatures which could result in the water circuit freezing.

• The system operation is designed around a closed water circuit. Do not use an open circuit design.

• Please turn on the main power supply to up to 12 hours before the start of the operation, and don’t turn off the power all the time during the period of use.

 Refrigerant piping

• THIS SYSTEM ADOPTS HFC REFRIGERANT (R410A) WHICH DOES NOT DESTROY THE OZONE LAYER.

• The characteristics of R410A refrigerant are: ease to absorb water, oxidizing membrane or oil, and its pressure is approximately 1.6 times higher that of R22. Accompanied with the new refrigerant the oil has also been changed. Therefore during installation work prevention of the invasion of water, dust, former refrigerant or oil is of a paramount importance. To prevent the charging of incorrect refrigerants into the system the service valve connection ports have also increased in size.

• The use of R410A tools is required for correct installation of the system.

• The use of the correct pipe sizes and wall thicknesses of copper pipe work is required for the correct installation of the system.

Install the Hydro Unit so that its tilting angle falls within the range below.

± 1°

• Ensure all refrigerant pipes are protected from the invasion of dust and water.

• Ensure all pipe work connections are tightened to the required torque settings detailed in this section.

• Perform an air tight using Oxygen Free Nitrogen (OFN) only.

• Evacuate the air in the pipe work using a vacuum pump.

• Check for refrigerant gas leaks at all connections throughout the pipe work.

The Air to Water Heat Pump system uses R410A refrigerant. It is important that copper pipes used for refrigerant piping have the following wall thickness:

• 0.8 mm for Ø6.4 mm, Ø9.5 mm and Ø12.7 mm

• 1.0 mm for Ø15.9 mm
