Electrical data, connections and wiring GENERAL INFORMATION IP rating The compressor terminal box IP rating according to IEC 529 is IP22 for all models. IP ratings is only valid when correctly sized cable glands of the IP rating is applied.
in reverse, but as a reverse rotation situation can go unnoticed for longer periods, phase monitors are recommended. For HC* series compressors, phase monitors are required. The selected phase monitor should lock out the compressor from operation in reverse. Electrical connections Danfoss scroll compressors are designed to operate without any assistance if running within the defined nominal voltage. PSC wiring is sufficient (see below).
Approvals and certifications GENERAL INFORMATION Approvals and certificates Danfoss scroll H-series compressors comply with the following approvals and certificates. Certificates are listed on the product datasheets: http://www.danfoss.
Operating conditions The compressor technology applied in Danfoss H-series scroll compressors in combination with PVE lubricant provides the best possible result in terms of reliability and compressor lifetime. The PVE lubricant is compatible with R22 which makes the Danfoss H-series scroll compressors a very versatile multi- refrigerant solution. Alkylbenzene oil Alkylbenzene oil can be applied in systems using HCFC refrigerants (R22).
Design piping General requirements Proper piping practices should be employed to: GENERAL INFORMATION 1. Ensure adequate oil return, even under minimum load conditions (refrigerant speed, piping slope). For validation tests see section “Manage oil in the circuit”. 2. Avoid condensed liquid refrigerant from draining back to the compressor when stopped (discharge piping upper loop). For validation tests see section “Manage off cycle migration”.
Danfoss scroll H series compressors in C8 version can be mounted in tandem assemblies. Such manifolding applications require special design considerations that go beyond the scope of this document. Please contact Danfoss for further information. By default, H series tandems are not factory-built, just provide tandem version compressors (feature 8). Connection Sizes Comp.1 Comp.
Design compressor mounting GENERAL INFORMATION General requirements Single requirements Compressors used in single applications must be mounted with flexible grommets. and the manifold assembly must be mounted with flexible grommets onto frame. Compressors used in parallel application must be mounted with rigid mounting spacers onto rails During operation, the maximum inclination from the vertical plane must not exceed 3 degrees.
The following sections focus on the causes and methods of mitigation for each of the above sources. For sound radiating from the compressors, the emission path is air and the sound waves are travelling directly from the machine in all directions.
Sound and vibration management GENERAL INFORMATION Mechanical vibrations Vibration isolation constitutes the primary method for controlling structural vibration. H-series scroll compressors are designed to produce minimal vibration during operations. The use of rubber isolators on the compressor base plate or on the frame of a manifolded unit is very effective in reducing vibration being transmitted from the compressor(s) to the unit. Rubber grommets are supplied with all H-series scroll compressors.
Manage operating envelope The operating envelope for H-series scroll R compressors is given in the figures below and guarantees reliable operations of the compressor for steady-state and transient operation. R22, R407C Model variation T Steady-state operation envelope is valid for a suction superheat within 9°F to 54°F range.

Manage operating envelope HP and LP must be monitored to respect operating envelope limitations.
GENERAL INFORMATION Manage superheat Requirement During normal operation, refrigerant enters the compressor as a superheated vapor. Liquid flood back occurs when a part of the refrigerant entering the compressor is still in liquid state. Liquid flood back can cause oil dilution and, in extreme situations lead to liquid slugging that can damage compression parts.
Manage superheat Test N° Purpose Test condition Pass criteria Solutions Liquid flood back testing must be carried out under expansion valve threshold operating conditions: a high pressure ratio and minimum evaporator load (A). Suction superheat >5K(9°F) 1. Check expansion valve selection and setting. 2. Add a suction accumulator*. Transient Tests must be carried out with most unfavorable conditions : • fan staging, • compressor staging •… Refer to flood back chart criteria 1.
PRODUCT INFORMATION GENERAL INFORMATION Manage off cycle migration R Off -cycle refrigerant migration happens: • when the compressor is located at the coldest part of the installation, refrigerant vapor condenses in the compressor. • or directly in liquid-phase by gravity or pressure difference. When the compressor restarts, the refrigerant diluted in the oil, or stored in evaporator, generates poor lubrication conditions and may reduce bearings life time.
Manage off cycle migration Test N° Migration test Purpose Check that there is no migration of refrigerant into the compressor (either liquid or vapour condensating) Test condition Energize CCH*. Stabilize the non-running system at a pressure equivalent to 41°F . Raise the system pressure equivalent to 68°F. When saturated condensing temperature reaches 68°F then start the unit.
Provide power supply and electrical protection GENERAL INFORMATION Wiring information “Electrical data, connections and wiring”) •H P safety switch and DGT must be wired in the safety chain. Other safety devices such as LP can be either hardware or software managed. •P rovide separate electrical supply for the heaters so that they remain energized even when the machine is out of service (e.g. seasonal shutdown).

Switch closed again Maximum 5 auto reset during a period of 12 hours, then manual reset. Contact M1-M2 opened Danfoss requires a minimum compressor running time of 2 minutes to ensure proper oil return and sufficient motor cooling. Additionally, compressor service life is based on a maximum of 12 starts per hour.
Control logic GENERAL INFORMATION Defrost logic recommendations 2. Transferring liquid refrigerant from one exchanger to the other one thanks to pressures. In reversible systems, the defrost logic can be worked out to limit liquid flood back effect by: 1. Running full load during defrost to share liquid refrigerant between all compressors. st to 4W p m ay all co EX ode Valv m e( pr ind V o .
Requirements H-series compressors are delivered with < 100 ppm moisture level. At the time of commissioning, system moisture content may be up to 100 ppm. During operation, the filter drier must reduce this to a level between 20 and 50 ppm. Solutions To achieve this requirement, a properly sized and type of drier is required. Important selection criteria’s include: • driers water content capacity, • system refrigeration capacity, • system refrigerant charge.
GENERAL INFORMATION Assembly line procedure Compressor storage Store the compressor not exposed to rain, corrosive or flammable atmosphere between -31°F and 158°F when charged with nitrogen and between -31°F and 131°F when charged with refrigerant. Compressor holding charge Each compressor is shipped with a nominal dry nitrogen holding charge between 4 and 10psi and is sealed with elastomer plugs.
Assembly line procedure Piping assembly Good practices for piping assembly is a pre-requisite to ensure compressor service life.
Assembly line procedure GENERAL INFORMATION Vacuum evacuation and moisture removal Requirements: • Never use the compressor to evacuate the system. • Connect a vacuum pump to both the LP and HP sides. • Evacuate the system to a pressure of 500 μm Hg (9.7 mpsi) absolute. Recommendations: • Energized heaters improve moisture removal. • Alternate vacuum phases and break vacuum with Nitrogen to improve moisture removal.
Commissioning • Crankcase heaters must be energized at least 8 hours in advance to remove refrigerant. • A quicker start-up is possible by “jogging” the compressor to evacuate refrigerant. Start the compressor for 1 second, then wait for 1 to 2 minutes. After 3 or 4 jogs the compressor can be started. This operation must be repeated for each compressor individually.
Dismantle and disposal ORDERING INFORMATION INTEGRATION INTO SYSTEM SYSTEM DESIGN PRODUCT INFORMATION GENERAL INFORMATION Danfoss recommends that compressors and compressor oil should be recycled by a suitable company at its site.
