Danfoss SHA(X)22e…L BOCK Condensing Units

About these instructions

Read these instructions before assembly and before using the condensing unit. This will avoid misunderstandings and prevent damage. Improper assembly and use can result in serious or fatal injury. Observe the safety instructions contained in these instructions and in the compressor instructions. These instructions must be passed onto the end customer along with the unit in which the condensing unit is installed.
Observe also the other documentation included with the condensing unit.

Note: 

According to Commission Regulation (EU) 2015/1095 of May 5th 2015 implementing Directive 2009/125/EC of the European Parliament and of the Council with regard to ecodesign requirements for professional condensing units, starting 2016 July 1st in the EU only products may be sold which fulfill minimum efficiency requirements. These minimum efficiency requirements must be documented by a certificate.

The matching certificate for your condensing unit can be created on the Internet on our software (VAP) under http://vap.bock.de/stationaryapplication/

Safety

Identification of safety instructions

 INFO

Important information or tips on simplifying work.

Qualifications required of personnel

 WARNING

Inadequately qualified personnel poses the risk of accidents, the consequence being serious or fatal injury. Work on compressors is therefore reserved for personnel which is qualified to work on pressurized refrigerant systems:

• For example, a refrigeration technician, refrigeration mechatronic engineer. As well as professions with comparable training, which enables personnel to assemble, install, maintain and repair refrigeration and air-conditioning systems. Personnel must be capable of assessing the work to be carried out and recognising any potential dangers.

Safety instructions

WARNING

Risk of accidents.
Refrigerating compressors are pressurised machines and as such call for heightened caution and care in handling.
The maximum permissible overpressure must not be exceeded, even for testing purposes.

Risk of burns! 

• Depending on the operating conditions, surface temperatures of over 60°C on the discharge side or below 0°C on the suction side can be reached.
• Avoid contact with refrigerant necessarily. Contact with refrigerant can cause severe burns and skin damage.

Intended use

 WARNING
The condensing unit may not be used in potentially explosive environments!

These assembly instructions describe the standard version of the condensing units named in the title manufactured by Bock. The condensing unit is intended for installation in a machine (within the EU according to the EU Directives 2006/42/EC Machinery Directive, 2014/68/EU Pressure Equipment Directive).

Commissioning is permissible only if the condensing unit has been installed in accordance with these assembly instructions and the entire system into which it is integrated has been inspected and approved in accordance with legal regulations.

Only refrigerants may be used which are released on http://vap.bock.de/stationaryapplication/

Any other use of the condensing unit is prohibited!

Areas of application

Operating limits

• The operating limits of the condensing units differ to the respective compressor.
  The really operating limits can be found on the Internet on our software (VAP) under vap.bock.de

Assembly

 INFO

• New compressors are factory-filled with inert gas. Leave this service charge in the compressor for as long as possible and prevent the ingress of air.
• Immediately after connecting the Plusbox to the refrigeration system, close the shut-off valves in the suction, discharge lines etc. and evacuate the compressor.
• Check the condensingn unit for transport damage before starting any work.

Setting Up

	Do not lift manually Use lifting gear Transport preferably via forklift truck, alternatively bolted to a pallet
	Provide adequate clearance for maintenance work. Distance from wall to condenser minimum 300 mm.
	Do not use in a dusty, damp atmosphere or a combustible environment.
	Set up on an even surface or frame with sufficient load bearing capacity. Only set up on a slant after following consulting. Preferably on vibration damper or mounting rubbers.
	Sun protection: If the condensing unit is set up outdoors, it has to be protected from direct sunlight.

Maintenance

Preparation

WARNING

Before starting any work on the compressor:

• Switch off the compressor and secure it to prevent a restart.
• Relieve compressor of system pressure.
• Prevent air from infiltrating the system!
  After maintenance has been performed:
• Connect safety switch.
• Evacuate compressor.
• Release switch-on lock.

Work to be carried out

To avoid system-related problems, the following service work must be carried out on the Plusbox:

• Cleaning: A dirty condenser leads to performance losses!
  Visual inspections and possible condenser cleaning therefore required on a monthly base. We recommend using compressed air and a soft brush for cleaning.
• Further maintenance work in accordance with the instructions for assembly on the compressor.
