Daikin EWWH955DZXEA2 [11/32] Shock absorbers

D-EIMWC01405-18EN- 11/32

Lifting instructions:

1) The equipment, slings, lifting accessories and handling procedures must meet local regulations and current standards.

2) To lift the machine, use only the holes on the heat exchangers.

3) Any lifting points should be used during handling.

4) Use lifting hooks with closing device exclusively. Hooks must be safely secured before handling.

5) The ropes and hooks used must have capacity suited to the load. Check the nameplate on the unit that indicates the

machine weight.

6) The installer must correctly select and use lifting equipment. We recommend using cables with minimum vertical

capacity equal to total machine weight.

7) The machine must be lifted slowly and well leveled. If necessary, adjust lifting equipment to guarantee levelling.

2.4 Positioning and assembly

The unit must be mounted on a level cement or steel base, suitable to support the overall weight of the complete machine

in operation, and must be positioned so as to provide space for maintenance, to allow the cleaning and/or the removal of

the evaporator and the condenser pipes. Refer to the figure below for the areas of respect. The condenser and evaporator

pipes are expanded inside the tube sheetto allow replacement, if necessary.

Fig. 4 - Unit positioning

The machine position should be designed to ensure access to all the safety and control devices. Never cover the safety

devices (safety valves, pressure switches), which, due to their importance, are subject to periodic checks. The safety

valves outlet must be connected before operations. For safety valve outlet pipe dimensions, we recommend applying

harmonized standards and EN13136.

These units include the installation of two safety valves for each exchanger, installed on an exchange tap, which always

maintains an active valve. Thus, both safety valves on each exchanger must be connected outside the engine room. These

pipes must be installed so that, in case the valve opens, the discharged refrigerant flow not invest people and/or things, or

can enter the building through windows and/or other openings.

The engine room must be adequately ventilated to prevent refrigerant accumulation inside that can deprive air of the right

oxygen content and thus cause asphyxiation. In this regard, we recommend the application of harmonized standard EN378-

3 (Safety and Environmental Requirements - Installation and protection of persons) or equivalent.

The air contaminated by a high percentage of refrigerant (see refrigerant safety sheet), can cause

asphyxiation, loss of mobility and consciousness if inhaled. Avoid eye and skin contact.

2.5 Shock absorbers

The anti-vibration rubber pads (optional), shipped separately, should be placed under the corners of the unit (except for

special specifications). These provide a minimum insulation. Pads are recommended on all installations where the

transmission of vibrations can be considerable. Also install the anti-vibration joints on water pipes to reduce the stress on

pipes, vibrations and noise.
