REMKO MXT 264 Operating And Installation Instructions Download Page 5

In particular, failure to observe the safety notes

may pose the following risks:

n

The failure of important unit functions.

n

The failure of prescribed methods of mainte-

nance and repair.

n

Danger to people on account of electrical and

mechanical effects.

1.5  Safety-conscious working

The safety notes contained in this manual, the

existing national regulations concerning accident

prevention as well as any internal company

working, operating and safety regulations must be

observed.

1.6  Safety instructions

for the operator

The operational safety of the units and compo-

nents is only assured providing they are used as

intended and in a fully assembled state.

n

The units and components may only be set up,

installed and maintained by qualified per-

sonnel.

n

Protective covers (grills) over moving parts

must not be removed from units that are in

operation.

n

Do not operate units or components with

obvious defects or signs of damage.

n

Contact with equipment parts or components

can lead to burns or injury.

n

The units and components must not be

exposed to any mechanical load, extreme

levels of humidity or extreme temperatures.

n

Rooms in which refrigerant may escape shall

be adequately aerated and ventilated. Other-

wise, a risk of suffocation or fire exists.

n

Do not leave children unsupervised when close

to the system.

n

Commissioning must be performed by author-

ised specialists exclusively. Deficient commis-

sioning may lead to water leaks, electric

shocks or fire. Commissioning must take place

as described in the user manual.

n

Only instruct authorised specialist personnel to

perform maintenance or servicing.

n

The system is filled with a flammable refrig-

erant. Never thaw any frozen unit components

independently!

n

Do not operate any further devices that pro-

duce high heat or naked flames in the same

room.

n

All housing parts and unit openings, e.g. air

inlets and outlets, must be kept clear.

n

The units must be inspected by a service tech-

nician to ensure that they are safe to use and

fully functional at least once yearly. Visual

inspections and cleaning may be performed by

the operator when the units are disconnected

from the mains.

1.7  Safety notes for installation,

maintenance and inspection

n

The refrigerant R32 used in the system is flam-

mable. If applicable, observe the local safety

conditions.

n

Keep the cooling circuit clear of other gases

and foreign substances. Only fill the cooling cir-

cuit with the refrigerant R32.

n

Only use the accessories, components and

appropriately marked parts provided. The use

of non-standardised components may result in

water leaks, electric shocks and fire.

n

Only install and store the units in rooms larger
than 4 m

2

. With a failure to comply, leaks may

result in the room filling with a flammable mix-

ture!
The minimum room size of 4 m

2

 required for

installation and storage pertains to the basic fill

quantity of the unit. This varies according to the

installation type and total fill quantity of the

system. The calculation must take place in

accordance with valid DIN standards. Make

sure that the installation site is suitable for safe

unit operation.

n

Only mount the unit components on structurally

suitable brickwork.

n

The units must not be installed in rooms in

which further devices that produce heat are

operated (heaters, open hearths).

n

Make sure the installation room is sufficiently

ventilated.

n

Interventions in the cooling circuit are only pos-

sible after completely draining the refrigerant.

Never solder or grind unit components!

n

Note that refrigerant may be odourless.

n

Never operate the air conditioning unit in a

humid room, such as a bathroom or laundry

room. If the humidity is too high, this can cause

short circuits on electrical parts.

n

The product must be correctly earthed at all

times, otherwise it may induce electric shocks.

n

Attach the condensate drain as described in

the operating manual. The inadequate

drainage of condensate can lead to water

damage in your apartment.

n

All persons who intervene in the cooling circuit

must hold a valid certificate from the chamber

of industry and commerce, which confirms their

ability to work with refrigerant.
