•
Note : The Fan Motors are pre-lubricated, and factory
sealed so no maintenance is necessary.
3. Condenser & Evaporator Coils – Clean and inspect at
regular intervals.
•
Check and remove the dirt and debris between the fins
using a soft brush and/or a suitable chemical coil cleaner
then rinse with clean water.
•
Check and remove any obstacles that may hinder the
airflow through the coils.
•
Repair any damage to fins and ensure any guards are
fitted correctly.
•
Do not use high pressure washers on coils – They
damage the fins.
4.
Controls
•
Check controller settings and operation.
•
Check calibration of temperature probe reading.
5.
Power Supply – Inspect at regular intervals.
•
Check the running current and voltage for the units.
•
Check the electrical wiring and tighten the if necessary.
6. Refrigerant Charge
•
Check the refrigerant charge by ensuring that the system
is operating correctly, and the system pressures are as
expected.
•
Carry out a full leak test.
7. Unit decommissioning and disposal
•
At the end of the system’s useful life, a suitably qualified
engineer should decommission it. The refrigerant and
compressor oil are classed as hazardous waste and as
such must be reclaimed and disposed of in the correct
manner, including completion of waste transfer
paperwork. The system components must be disposed of
or recycled as appropriate in the correct manner.
8.
Component replacement (connections tightening
torque value)
•
Refer Table 11 for the recommended torque tightening
of all the components in outdoor unit.
Table 11: Torque Tightening

Warranty
•
The warranty as provided by J & E Hall on its products
is subject to correct application, siting, and installation
procedures together with subsequent recorded
maintenance/servicing carried out in accordance with
our recommendations. Failure to do so could result in the
withdrawal of our warranty. Please go to our website

F-Gas Requirement
The equipment covered in this Technical Manual relies on
fluorinated greenhouse gases
R448A (GWP: 1387) and
R449A (GWP: 1397) for their functioning.
All unit models come from the factory pressurized with OFN
(Oxygen Free Nitrogen) only.
F-Gas Regulation EU 517/2014 requires leak testing is
based on the charge size in tonnes of CO
2
equivalent
specified in below table. Starting 1st January 2017, the
requirement for leak detection and maintaining system logs
changes from 3kg HFC to 5 tonnes CO2 equivalent.

Leak Inspection Frequency
3.6 to 36 kg R448A
3.6 to 35.8 kg R449A
•
At least once every year.
(5 to < 50 TCO

eq)
•
At least once every 2 years if
a fixed leak detection system
is fitted.

A refrigerant charge label is supplied with each unit (inside
the electrical box). The total refrigerant charge for the
system and the TCO
2
Eq value must be entered on the label
with indelible ink and must be adhered in the proximity of
the product charging port. The label supplied will represent
the refrigerants approved for use with that unit.
