INSPECTION AND MAINTENANCE
6 720 803 687 (2012/11) 51
9.5 SERVICING THE EXTERNAL UNIT
9.5.1 GENERAL NOTES
The system uses R410Arefrigerant only.
▶ Only qualified and authorised refrigeration engineers may work on the
refrigerant system.
▶ During installation work, use the tools and components specifically
provided for handling R410A refrigerant.
▶ Check for leaks in the refrigerant system. Escaping refrigerant coming
into contact with a naked flame will produce poisonous gases.
▶ Never release refrigerant to the atmosphere.
9.5.2 VISUAL INSPECTION OF EXTERNAL UNIT
▶ With the external unit running pay attention to any unusual noise.
▶ Check for signs of corrosion and worn or damaged parts. Pay
particular attention to refrigerant lines, insulation and connections.
▶ Check for loose fasteners.
▶ Check for blocked condensate drain or damaged trace heating cable
in the condensate pan.
▶ Check for contamination and clean or repair, if required.
▶ External unit faults are signalled by LED1 (green) and LED2 (red) on
the PCB in the external unit.
▶ Clean away any obstructions i.e. leaves
9.5.3 CLEANING THE EXTERNAL UNIT AIR INTAKE
▶ Check evaporator fins and air intake at the rear and the left hand side
of the external unit and clean, if required. Clearing any obvious
obstructions (i.e. leaves)
▶ Switch off the external unit at the on/off switch.
▶ Use warm soapy water and a damp cloth if necessary.
▶ The evaporator fins can be rinsed off using a watering can fitted with
a rose/spray head if necessary.
▶ Cut or remove vegetation/foliage surrounding the outdoor unit to at
least the specified clearances around the unit. (Fig. 19, Table 6,
page 23)
▶ Switch the external unit back on as soon as possible, and only if safe
to do so.
▶ Check the refrigerant pipe insulation for damage and repair if
necessary.
9.5.4 COMPLETING INSPECTION AND MAINTENANCE
▶ Install casing parts.
▶ Complete and sign the inspection and maintenance report in this
manual ( Chapter 9.6).
DANGER: Risk to life due to escaping refrigerant.
Escaping refrigerant can result in asphyxiation and frost
bite in the case of contact at its exit point.
▶ When refrigerant escapes, never touch any
components of the air to water heat pump and ensure
adequate fresh air ventilation.
▶ Avoid skin or eye contact with refrigerant.
▶ Seek medical attention if you get refrigerant on your
skin or in your eyes.
NOTICE: Damage from wet conditions!
Ingress of rain, humidity or dust can damage the PCB
inside the external unit.
▶ Never work on the external unit when it is raining.
▶ Following work on the terminal strip check that the
service cover sits firmly.
Chapter 10 includes an overview of fault displays.
NOTICE: Damage through incorrect cleaning.
▶ Carefully brush off dirt by hand or with a soft brush.
▶ Never use high pressure cleaners or water hoses for
cleaning the external unit.
▶ If cleaning by hand wear gloves to protect your hands.
▶ Do not use any cleaning products that are abrasive or
contain acid or chlorine.
NOTICE:
▶ If the power to the external unit has been off for a
period of time greater than 5 minutes, the initial
power up period of 12 hours (Chapter 6.1.1,
Page 32) must be followed before a heat demand is
requested. This is to ensure that the compressor is
warmed up sufficiently to avoid any liquid refrigerant
from entering the compressor. This is particularly
important during colder periods. If this 12 hour time
period cannot be met damage to the outdoor unit may
result.
