Preliminary Checks; Check Equipment Received - Danfoss BW05 Installation, Operation And Maintenance Instructions

The necessary protection equipment must be available, and
appropriate fire extinguishers for the system and the
refrigerant type used must be within easy reach.
Do not siphon refrigerant.
Avoid spilling liquid refrigerant on skin or splashing it into
the eyes. Use safety goggles. Wash any spills from the skin
with soap and water. If liquid refrigerant enters the eyes,
immediately and abundantly flush the eyes with water and
consult a doctor.
Never apply an open flame or live steam to a refrigerant
container. Dangerous overpressure can result. If it is
necessary to heat refrigerant, use only warm water.
During refrigerant removal and storage operations follow
applicable regulations. These regulations, permitting condi-
tioning and recovery of halogenated hydrocarbons under
optimum quality conditions for the products and optimum
safety conditions for people, property and the environment
are described in standard NFE 29795.
Any refrigerant transfer and recovery operations must be
carried out using a transfer unit. A 3/8" SAE connector on the
manual liquid line valve is supplied with all units for
connection to the transfer station. The units must never be
modified to add refrigerant and oil charging, removal and
purging devices. All these devices are provided with the
units. Please refer to the certified dimensional drawings for
the units.
Do not re-use disposable (non-returnable) cylinders or
attempt to refill them. It is dangerous and illegal. When
cylinders are empty, evacuate the remaining gas pressure,
and move the cylinders to a place designated for their
recovery. Do not incinerate.
Do not attempt to remove refrigerant circuit components or
fittings, while the machine is under pressure or while it is
running. Be sure pressure is at 0 kPa before removing
components or opening a circuit. If the refrigerant circuit is
open to carry out a repair, all circuit openings must be
plugged, if the repair takes longer than 30 minutes. This
prevents humidity from contaminating the circuit, especially
the oil. If the work is expected to take longer, charge the
circuit with nitrogen.
Do not attempt to repair or recondition any safety devices
when corrosion or build-up of foreign material (rust, dirt,
scale, etc.) is found within the valve body or mechanism. If
necessary, replace the device. Do not install safety valves in
series or backwards.
ATTENTION: No part of the unit must be used as a walkway,
rack or support. The refrigerant lines can break under the
weight and release refrigerant, causing personal injury.
Do not climb on a machine. Use a platform, or staging to
work at higher levels.

Use mechanical lifting equipment (crane, hoist, winch, etc.)
to lift or move heavy components. For lighter components,
use lifting equipment when there is a risk of slipping or
losing your balance.
Use only original replacement parts for any repair or compo-
nent replacement. Consult the list of replacement parts that
corresponds to the specification of the original equipment.
Do not drain water circuits containing industrial brines,
without informing the technical service department at the
installation site or a competent body first.
Close the entering and leaving water shutoff valves and
purge the unit water circuit, before working on the compo-
nents installed on the circuit (screen filter, pump, water flow
switch, etc.).
Periodically inspect all valves, fittings and pipes of the
refrigerant and hydronic circuits to ensure that they do not
show any corrosion or any signs of leaks.

2 PRELIMINARY CHECKS

2.1 - Check equipment received

• Inspect the unit for damage or missing parts. If damage is
detected, or if shipment is incomplete, immediately file a
claim with the shipping company.
• Confirm that the unit received is the one ordered.
Compare the name plate data with the order.
• The unit name plate must include the following
information:
- Version number
- Model number
- CE marking
- Serial number
- Year of manufacture and test date
- Refrigerant used and refrigerant class
- Refrigerant charge per circuit
- Containment fluid to be used
- PS: Min./max. allowable pressure (high and low
pressure side)
- TS: Min./max. allowable temperature (high and low
pressure side)
- Globe valve cut-out pressure
- Pressure switch cut-out pressure
- Unit leak test pressure
- Voltage, frequency, number of phases
- Maximum current drawn
- Maximum power input
- Unit net weight
• Confirm that all accessories ordered for on-site installation
have been delivered, and are complete and undamaged.
• Do not keep the BW05 units outside where they are exposed
to the weather, as the sensitive control mechanism and the
electronic modules may be damaged.
The unit must be checked periodically during its whole
operating life to ensure that no shocks (handling accessories,
tools etc.) have damaged it. If necessary, the damaged parts
must be repaired or replaced. See also chapter "Mainte-
nance".
