Thank you for purchasing this Daikin HRV.

The original instructions are written in English. All other languages are translations of the original instructions.

HRV – Heat Reclaim Ventilation

Please read this installation manual carefully and install the unit properly to keep it at full capacity for a long time.

Please prepare some necessary parts, for example round hoods, air suction/discharge grilles etc., before the installation of the unit.

Safety considerations

Please read these "Safety considerations" carefully before installing air conditioning equipment and be sure to install it correctly. After completing the installation, make sure that the unit operates properly during the start-up operation. Please instruct the customer on how to operate the unit and keep it maintained.

Also, inform customers that they should store this installation manual along with the operation manual for future reference.

This air conditioner comes under the term “appliances not accessible to the general public”.

Meaning of warning and caution symbols

WARNING Failure to follow these instructions properly may

result in personal injury or loss of life.

CAUTION Failure to observe these instructions properly

may result in property damage or personal injury, which may be serious depending on the circumstances.

WARNING

 Never inspect or service the unit by

yourself. Ask a qualified service person to perform this work.

 Electric shock may result. Before

servicing the unit, always shut off power.

 Persons servicing the unit are

required to wear gloves.

 All wiring must be performed by an

authorized electrician and must comply with the applicable legislation.

 Always use the air filter.

If the air filter is not used, heat exchange elements will be clogged, possibly causing poor performance and subsequent failure.

 Do not change operations suddenly.

It can result not only in malfunction but also failure of switches or relays in the body.

 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 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.

 Do not use an HRV or an air

suction/discharge grille in the following places:

- Places such as machinery plants and chemical plants where gas, which contains noxius gas or corrosive components of materials such as acid, alkali, organic solvent and paint, is generated.

- Places such as bathrooms subjected to moisture. Electric leak or electric shock and other failure can be caused.

VAM350~2000FA Total Heat Exchanger HRV (Heat Reclaim Ventilation) 4PW90548-1 (2014.03)

Installation manual

- Places subjected to high temperature or direct flame. Avoid a place where the temperature near the HRV unit and the air suction/discharge air grille exceeds 50°C. If the unit is used at high temperature, deformed air filter and heat exchange element or burned motor result. Unit ambient temperature conditions should be between -15°C and 50°C (80% relative humidity or less)

- Places subjected to much carbon black.

- Carbon black attaches to air filter and heat exchange element, disabling them.

- The equipment is not intended for use in a potentially explosive atmosphere.

 Improper installation or attachment

of equipment or accessories could result in electric shock, short-circuit, leaks, fire or other damage to the equipment. Be sure only to use accessories, optional equipment and spare parts made by Daikin which are specially designed for use with the products as of subject in this manual and have them installed by an installer.

Installation

Installation position

CAUTION  Install the unit in a place strong enough to

support its weight.

Poor installation is hazardous. It also causes vibrations and unusual operating noise.

 Provide the service space and the inspection

holes.

(Be sure to provide the inspection holes to inspect the air filters, the heat exchange elements and fans.)

 Do not install the unit directly against a ceiling or

wall.

(If the unit is in contact with the ceiling or wall, it can cause vibration.)

 This is a class A product. In a domestic

environment this product may cause radio interference in which case the user may be required to take adequate measures.

CAUTION on installing the ducts

 The parts marked with (*) are effective in reducing

blowing noise.

 When using the unit at a quiet place, use the optional

silencer box and flexible duct at the part of the air discharge outlet on the indoor side “SA” (supply air to room) of the unit, to counter the noise.

 When selecting installation materials, consider the

required volume of air flow and noise level in that particular installation.

 When the outdoor air infiltrates into the ceiling and the

temperature and humidity in the ceiling become high, insulate the metal portions of the unit.

 Access inside the unit is only allowed through the

service hole. Install grilles in case no ducts are installed.

 Unit sound pressure level is less than 70dB (A).

HRV

2 3

HRV

following conditions:  There shall be no danger of water entering the control box

(condensation, nearby piping, etc.).

 The unit shall be sufficiently fixated.  External switchbox wiring shall point downwards.  Fan shaft has to remain horizontally.

Duct connection

Do not connect the ducts as follows

 VAM1500F, VAM2000F

Extreme bend

Do not bend the duct over 90°

Reduce the diameter of the duct to be connected.

Do not reduce the duct diameter halfway.

Multi bend

1 The minimal radius of bends for flexible ducts are as follows:

300 mm duct: 200 mm diameter 375 mm duct: 250 mm diameter

2 To prevent air leakage, wind aluminum tape round the section

after the duct connecting flange and the duct are connected.

3 Install the opening of the indoor air intake (SA) as far as possible

from the opening of the exhaust suction (RA).

4 Use the duct applicable to the model of unit used (Refer to the

outline drawing).

5 Install the two outdoor ducts with down slope (slope of 1/50 or

more) to prevent entry of rain water. Also, provide insulation for both ducts to prevent dew formation. (Material: Glass wool of 25 mm thick)

6 If the level of temperature and humidity inside the ceiling is

always high, install a ventilation equipment inside the ceiling.

7 Insulate the duct and the wall electrically when a metal duct is to

be penetrated through the metal lattice and wire lattice or metal lining of a wooden structure wall.

Installation manual

 Use Ø250 mm round ducts for the SA (supply air) and RA

(return air) sides

1. Loosen the 12 screws off the SA (supply air) side and remove

the connection chamber. Be sure to tighten up these screws back in position in order not to allow any air leak from the unit.

2. Fix the duct connecting flanges (option) with their accompanying

12 screws.

 Introducing the silencers and other options.

This model handles a high air flow rate. To reduce the blow-out noise, some optional attachments are available: silencer, flexible duct, thin air intake/exhaust grille, etc.

1. Remove the connection chamber off the SA (supply air) side and

attach the upper and lower silencers.

2. Now fix the duct connecting flanges (option) and connect the

Ø250 mm flexible ducts.

System Standard method

• Up to 16 units can be controlled with the remote controller for HRV. (A system with two remote controls can be created in the master/slave switching.)

• All HRV operations can be used and indicated.

• Operation monitor output and humidifier operation are possible using Adapter PCB.

• Remote control cord should be procured locally. (Maximum cord length: 500 m)

• A combined total of up to 16 air conditioners and the HRV can be controlled.

• The HRV ventilation mode can be operated independently when air conditioners are not being used.

• Using the local setting of the remote controller for air conditioners, various settings such as precool/pre-heat reservation on/off, ventilation flow rate, ventilation mode, etc.

• Since all VRV units are connected to a single line in view of installation, all VRV units are subjects for operation.

• If there are problems operating all VRV units, do not use this system.
