Pre-Installation
The unit must be installed by a suitably qualified
tradesperson and all electrical wiring must be completed
by a licensed electrical contractor in accordance with
all local Standards.
Safety
The installation must be overseen by a qualified
person, in order to avoid an incorrect installation that
could damage to the unit or cause injuries to people.
Any faults and or leaks must be repaired immediately
before the unit continues to operate. If repairs have
been carried out to the unit then operation of the safety
devices and parameter must be rechecked.
If a refrigerant leak occurs, remove the complete charge
using a recovery unit and store the refrigerant in mobile
container.
Note: care is to be taken as the refrigerant
can breakdown due to high temperature, these
refrigerants by-products are dangerous.
Once the leak has been repaired recharge the unit with
the correct filling weight and the type found on the
unit’s nameplate.
Movement and Storage
The unit must not be transported, moved or stored at
greater than a 30° angle from the upright position. Store
the unit in a dry area until required.
Note: ensure the correct refrigerant gas is used to
recharge the unit as an incorrect gas can cause
damage beyond repair to the compressor.
Do not use oxygen to purge lines or to pressurize a unit
for any purpose. Oxygen gas reacts violently with oil,
grease and other common substances. Use only refrigerant
or dry nitrogen for testing.
Never exceed the specied maximum operating pressures.
Do not un-weld or ame cut the refrigerant lines
including any refrigerant circuit components
until the entire refrigerant (liquid and vapour)
has been removed from unit. Traces of vapour
should be displaced with dry nitrogen.
Refrigerant in contact with an open ame will produces
toxic gases.
Ensure that the necessary safety protection
equipment is available when servicing. Have the
appropriate re extinguishers for that system.
Do not siphon refrigerant.
Avoid spilling liquid refrigerant onto the 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 ush the eyes with
water and consult medical advice.
Note: Never apply an open flame or live stream
to a refrigerant container. This can dangerously
overpressure and cause an explosion.
Compressor oil type : 3MA POE
The heating system must be pressure tested and
air vented completely.
Filling water and supplemented water must be
drinking water quality (colourless, clear ,free
from sediments)
Filling water and supplemented water must be
pre-ltered. (pore size max. 5um)
