Precautions
Read Safety Precautions Before Operation and Installation
Incorrect installation due to ignoring instructions can cause serious damage or injury.
Safety Precautions
13. When a FLAMMABLE REFRIGERANT is used, the requirements for installation space of
appliance and /or ventilation requirements are determined according to
-- the mass charge amount(M) used in the appliance,
--the installation location,
--the type of ventilation of the location or of the appliance.
WARNING
1.
Installation (Space)
- That the installation of pipe-work shall be kept to a minimum.
- That pipe-work shall be protected from physical damage.
- Where refrigerant pipes shall be compliance with national gas regulations.
- That mechanical connections shall be accessible for maintenance purposes.
- In cases that require mechanical ventilation, ventilation openings shall be kept clear of obstruction.
- When disposing of the product is used, be based on national regulations, properly processed.
2. Servicing
- Any person who is involved with working on or breaking into a refrigerant circuit should
hold a current valid certificate from an industry-accredited assessment authority, which
authorises their competence to handle refrigerants safely in accordance with an industry
recognised assessment specification.
3. Maintenance and repair requiring the assistance of other skilled personnel shall be carried
out under the supervision of the person competent in the use of flammable refrigerants.
4. Do not use means to accelerate the defrosting process or to clean, other than those
recommended by the manufacturer.
5. The appliance shall be stored in a room without continuously operating ignition sources
(for example: open flames,an operating gas appliance or an operating electric heater)
6. Be more careful that foreign matter(oil, water,etc) does not enter the piping. Also, when
storing the piping, securely seal the opening by pinching, taping, etc.
7. Do not pierce or burn.
8.
Be aware that refrigerants may not contain an odour.
9.
All working procedure that affects safety means shall only be carried by competent
persons.
10.
Appliance shall be stored in a well -ventilated area where the room size corresponds to
the room area as specifiec for operation.
11. The appliance shall be stored so as to prevent mechanical damage from occurring.
12. Joints shall be tested with detection equipment with a capability of 5 g/year of refrigerant
or better, with the equipment in standstill and under operation or under a pressure of at
least these standstill or operation conditions after installation. Detachable joints shall NOT
be used in the indoor side of the unit(brazed, welded joint could be used).

or the required minumum floor area to install an applicance with refrigerant charge A
M(kg) shall be in accordance with following:
Where.
m is the allowable maximum charge in a room, in kg;
M is the refrigerant charge amount in appliance, in kg;
A is the required minimum room area, in m ;
A is the room area, in m ;
LFL is the lower flammable limit, in kg/m ;
h is the release height, the vertical distance in metres from the floor to the point of
release when the appliance is installed;
h h h = ( inst+ rel) or 0,6 m whichever is higher
hrel is the release offset in metres from the bottom of the appliance to the point of
release
hinst is the installed height in metres of the unit
Reference installed heights are given below:
0.0 m for portable and floor mounted;
1.0m for window mounted;
1.8m for wall mounted;
2.2m for ceiling mounted;
If the minimum installed height given by the manufacturer is higher than the reference
installed height, then in addition Amin max and m for the reference installed height have to
be given by the manufacturer. An appliance may have multiple reference installed heights.
In this case, Amin max and m calculations shall be provided for all applicable reference
installed heights.
For appliances serving one or more rooms with an air duct system, the lowest opening of the
duct connection to each conditioned space or any opening of the indoor unit greater than
5 cm , at the lowest position to the space, shall be used for h0 0. However, h shall not be less
than 0,6 m. Amin shall be calculated as a function of the opening heights of the duct to the
spaces and the refrigerant charge for the spaces where leaked refrigerant may flow to,
considering where the unit is located. All spaces shall have a floor area more than Amin.
