Instructions

8510196P04H - FRCC.PI.049.A4.02

1 - Introduction

These instructions pertain to the Maneurop® MT,

MTZ,VTZ & NTZ compressors used for refrigera-

tion systems. They provide necessary informa-

tion regarding safety and proper usage of this

product.

2 – Handling and storage

• Handle the compressor with care. Use the

dedicated handles in the packaging. Use the

compressor lifting lug and use appropriate

and safe lifting equipment.

• Store and transport the compressor in an

upright position.

• Store the compressor between -35°C and

50°C.

• Don’t expose the compressor and the packa-

ging to rain or corrosive atmosphere.

3 – Safety measures before assembly

Never use the compressor in a ammable at-

mosphere.

• The compressor ambient temperature may

not exceed 50°C during o-cycle.

• Mount the compressor on a horizontal at

surface with less than 3° slope.

• Verify that the power supply corresponds to

the compressor motor characteristics (see

nameplate).

• When installing MTZ,VTZ or NTZ, use equip-

ment specically reserved for HFC refrigerants

which was never used for CFC refrigerants.

• Use clean and dehydrated refrigeration-grade

copper tubes and silver alloy brazing material.

• Use clean and dehydrated system components.

• The piping connected to the compressor must

be exible in 3 dimensions to dampen vibrations.

4 - Assembly

• Slowly release the nitrogen holding charge

through the schrader port.

• Remove the gaskets when brazing rotolock

connectors.

• Always use new gaskets for assembly.

• Connect the compressor to the system as

soon as possible to avoid oil contamination

from ambient moisture.

• Avoid material entering into the system while

cutting tubes. Never drill holes where burrs

cannot be removed.

• Braze with great care using state-of-the-art tech-

nique and vent piping with nitrogen gas ow.

• Connect the required safety and control de-

vices. When the schrader port is used for this,

remove the internal valve.

5 – Leak detection

Never pressurize the circuit with oxygen or

dry air. This could cause re or explosion.

• Do not use dye for leak detection.

• Perform a leak detection test on the complete

system.

• The low side test pressure must not exceed 25

bar.

• When a leak is discovered, repair the leak and

repeat the leak detection.

6 – Vacuum dehydration

• Never use the compressor to evacuate the

system.

• Connect a vacuum pump to both the LP & HP

sides.

• Evacuate the system to a pressure of 500 µm

Hg (0.67 mbar) absolute.

• Do not use a megohmmeter nor apply power

to the compressor while it is under vacuum as

this may cause internal damage.

7 – Electrical connections

• Switch o and isolate the main power supply.

See overleaf for wiring details.

• The compressor is protected against excess

current and temperature by an internal over-

load protector. Follow local regulations regar-

ding power line protection. The compressor

must be connected to earth.

• All electrical components must be selected as per

local standards and compressor requirements.

8 – Filling the system

• Keep the compressor switched o.

• Fill the refrigerant in liquid phase into the

condenser or liquid receiver. The charge must

be as close as possible to the nominal system

charge to avoid low pressure operation and

excessive superheat.

• Keep the refrigerant charge below 2.5 kg per

compressor cylinder if possible. Above this

limit; protect the compressor against liquid

ood-back with a pump-down cycle or suc-

tion line accumulator.

• Never leave the lling cylinder connected to

the circuit to avoid overlling.

9 – Verification before commissioning

Use safety devices such as safety pressure

switch and mechanical relief valve in compliance

with both generally and locally applicable regu-

lations and safety standards. Ensure that they

are operational and properly set.

Check that the settings of high-pressure swit-

ches and relief valves don’t exceed the maximum

service pressure of any system component.

• A low-pressure switch is recommended to

avoid vacuum operation. Minimum setting

0.1 bar.

• Verify that all electrical connections are pro-

perly fastened and in compliance with local

regulations.

• When a crankcase heater is required, it must be

energized at least 12 hours before initial start-

up and start-up after prolonged shutdown.

10 – Start-up

• All service valves must be in the open position.

• Balance the HP/LP pressure.

• Energize the compressor. It must start

promptly. If it does not, switch it o

immediately. Possible single phase miswiring

can cause burn-out within seconds.

• If the compressor does not start, check wiring

conformity and voltage on terminals.

• If the internal overload protector trips out, it

must cool down to 60°C to reset. Depending

on ambient temperature, this may take up to

several hours.

11 – Check with running compressor

• Check current draw and voltage.

• Check suction superheat to reduce risk of

slugging.

• When a sight glass is provided observe the oil

level at start and during operation to conrm

that the oil level remains visible.

• Respect the operating limits as printed overleaf.

• Check all tubes for abnormal vibration. Move-

ments in excess of 1.5 mm require corrective

measures such as tube brackets.

• When needed, additional refrigerant in the

liquid phase may be added in the low-pressure

side as far as possible from the compressor.

The compressor must be operating during

this process.

• Do not overcharge the system.

• Never release refrigerant to the atmosphere.

• Before leaving the installation site, carry out

a general installation inspection regarding

cleanliness, noise and leak detection.

• Record type and amount of refrigerant charge

as well as operating conditions as a reference

for future inspections.

12 - Maintenance

Internal pressure and surface temperature

are dangerous and may cause permanent inju-

ry.Maintenance operators and installers require

appropriate skills and tools. Tubing temperature

may exceed 100°C and can cause severe burns.

Ensure that periodic service inspections to

ensure system reliability and as required by local

regulations are performed.

To prevent system related compressor problems,

following periodic maintenance is recommended:

• Verify that safety devices are operational and

properly set.

• Ensure that the system is leak tight.

• Check the compressor current draw.

• Conrm that the system is operating in a way

consistent with previous maintenance re-

cords and ambient conditions.

• Check that all electrical connections are still

adequately fastened.

• Keep the compressor clean and verify the ab-

sence of rust and oxidation on the compres-

sor shell, tubes and electrical connections.

13 - Warranty

Always transmit the model number and serial nu-

mber with any claim led regarding this product.

The product warranty may be void in following

cases:

• Absence of nameplate.

• External modications; in particular, drilling,

welding, broken feet and shock marks.

• Compressor opened or returned unsealed.

• Rust, water or leak detection dye inside the

compressor.

• Use of a refrigerant or lubricant not approved

by Danfoss.

• Any deviation from recommended instruc-

tions pertaining to installation, application or

maintenance.

• Use in mobile applications.

• Use in explosive atmospheric environment.

• No model number or serial number trans-

mitted with the warranty claim.

14 – Disposal

Instalacji i serwisu sprężarki dokonuje wyłącznie wykwalikowany personel. Należy postępować zgodnie z poniższymi instrukcjami i zasadami dobrej prak-

tyki inżynierskiej w chłodnictwie, odnoszącymi się do instalacji, oddawania do użytku, konserwacji i serwisu.

Sprężarka może być wykorzystywana wyłącznie

w celu (celach), do jakiego (jakich) została

przeznaczona, obejmujących zakres jej zastosowań

(patrz „limity pracy ”).

Zapoznaj się z poradnikiem aplikacyjnym oraz z kartami

katalogowymi dostępnymi na stronie cc.danfoss.com

Dostarczona sprężarka znajduje się

pod ciśnieniem azotu (przedział od

0,3 do 0,7 bara), dlatego też nie może

być podłączana od razu; patrz paragraf

„montaż” w celu uzyskania dalszych

informacji.

W każdym przypadku należy

spełnić wymagania EN378 (lub innego

lokalnego przepisu bezpieczeństwa).

Sprężarkę należy przenosić ostrożnie

w pozycji pionowej (maksymalne

odchylenie od pionu: 15°)
