Installation manual

Introduction
The information in this manual is to provide general
assistance in the selection of equipment. The
responsibility for the specification of the equipment must
however remain that of the installer and any consultants
or designers concerned with the installation, specification
or design.
Any water distribution and central heating installation
must comply with the relevant recommendation of the
current version of the Regulations and British Standards
listed below:
Building Regulations
I.E.E. Requirements for Electrical Installations (BS7671)
Water Regulations Manual Handling Operations
Regulations
British Standards BS6798, BS5449, BS5546,
BS5440:1, BS5440:2, CP331:3, BS6700, BS7593 and
BS7671. Health and Safety Document No 635.
When installing unvented hot water systems section G3 of
the Building Regulations should be adhered to. An
annual inspection would also be required to ensure safe,
long term operation.
Please note: Kingspan Renewables do not accept any
responsibility for matters of specification, design or
selection or for the effectiveness of an installation
containing one of our products unless we have been
specifically requested to do so.
Important Note - Included in the Aeromax Plus
introduction pack is the Kingspan Renewables 2-year
extended warranty registration card. Please use this card
to register within 30 days of commissioning/occupation if
new build, and ensure the homeowner benefits from the
extended warranty. This needs to be completed by both
the Approved Installer and the current homeowner (or a
signature of developer is required if new build). The
registration card is free post and is logged by our warranty
department.
In the unlikely event of failure of the Aeromax Plus heat
pump, return of the card ensures that the homeowner’s
warranty claim is dealt with efficiently.
All goods are sold subject to our Conditions of Sale (see
Web site for details).
• This heat pump adopts the new HFC refrigerant
(R410A) which does not destroy ozone layer.
• R-410A refrigerant operates at 50%-70% higher
pressures than R-22. Be sure that servicing equipment
and replacement components are designed to operate
with R-410A.
• R-410A refrigerant cylinders have a dip tube which
allows liquid to flow out with the cylinder in a vertical
position with the valve at the top.
• R-410A systems should be charged with liquid
refrigerant. Use a commercial type metering device in
the manifold hose in order to vaporize the liquid
refrigerant before it enters in the unit.
• As for other HFC, R-410A refrigerant is only
compatible with oils recommended by the compressor
manufacturer.
R-410A - General info
• A vacuum pump is not enough to remove moisture
from oil.
• Oils absorb moisture rapidly. Do not expose oil to
atmosphere.
• Never open system to atmosphere while it is under
vacuum.
• When the system must be opened for service, break
vacuum with dry nitrogen and replace filter driers.
• Do not vent R-410A into the atmosphere.
Use this unit only for factory approved applications.
The capacity and unit code are stated on the nameplate
data.
CAUTION:
• Do not leave the heat pump casing open to atmosphere any
longer than the minimum required for installation.
• Oil in the compressor is extremely susceptible to moisture
absorption.
• The maximum residual quantity of oil used for tubing is 40
mg/10m.
