Page 5: General Information
General Information The Lailey and Coates Split System consists of two major parts: The Internal and External Units. They are connected via refrigeration pipes and an ELV, shielded, communication Cable. The external units can either be wall mounted or hard-standing but should be secured via suitably designed mounting systems available from Lailey and Coates. -

Page 7: Installation Of External Unit
Installation of External Unit When locating the External Unit the following considerations should be taken into account: ● If wall mounting ensure that the structure is sufficiently solid to bear the weight of the unit without causing vibration. ● If floor mounted ensure base is solid with no likelihood of subsidence. ● Select a location so as to minimise disruption to neighbours and avoid close proximity to bedrooms. In accordance with MCS standards. ● Ensure adequate access to and around the unit for maintenance and non‐ restriction of airflow. ● Close proximity to possible gas leaks or electrical equipment should be avoided. ● When in defrost excess water will drain from the unit so ensure an adequate method of disposal to same. -
Page 8: Installation Of Internal Unit
Installation of Internal Unit When locating the Internal Unit the following considerations should be taken into account: ● If wall mounting ensure that the surface is flat, non‐combustible and sufficiently solid to bear the weight of the unit without causing vibration. ● Provision should be made for sufficient access to ensure ease of maintenance. ● Ensure the unit is not exposed to extremes of temperature. ● Avoid close proximity to possible inflammable gas leakage. ● Maximum refrigeration pipe length See page Please note: a wall bracket and mounting template are supplied with the Internal Unit.

Plumbing Installation Warnings This unit must be installed to conform with all relevant local standards and regulations by suitably qualified engineers. Installation should be capable of withstanding a maximum water pressure of 10 bar. Mid-position zone valves should not be used to switch between heating and hot water. Hydraulic zone valves are not suitable for use with this system. - Page 13 Plumbing Installation Continued Internal Pump Settings If used with radiators, pump should be set to AUTO ● If used with under floor heating, pump should be set to MANUAL and adjusted to ● Settings 1, 2 or 3 to achieve required flow rate as per table above.

Page 14: Refrigeration Installation
Refrigeration Installation. Warnings: This unit must be installed to conform with all relevant local standards and regulations by suitably qualified engineers. When brazing the pipe always use OFN. This unit is only suitable for R410A Refrigerant. This product contains fluorinated greenhouse gasses covered by the Kyoto Protocol. Do not vent gasses into atmosphere. - Page 15 Refrigeration Installation Continued Please note: ● Refrigerant pipes can be connected to either the top or bottom of the unit. If using top connections ensure bottom connections are tight and vice-versa. ● Pre‐Pressure Testing and Commissioning, ensure Service valves are open and Schrader valves are fully closed. Precautions when adding R410A Be sure to charge the specified amount of refrigerant in liquid state to the liquid pipe. As R 410A is a mixed refrigerant, adding it in gas form may cause the refrigerant composition to change, preventing normal operation.

Page 16: Dip Switch Settings
Dip Switch Settings Both internal and external Units have a bank of PCB dip switches. These should be checked prior to initial start-up to ensure correct operation of the Heat Pump. Any changes to these settings should be carried out with the Heat Pump powered down to enable the PCB to recognise these changes. -
Page 17: Pre-Operation Checklist
Pre-Operation Checklist Prior to initial start-up please ensure following: General: Dip Switches are correctly set to both External and Internal Units. See page There is no obvious damage to the body or components of the units. Units are securely fixed to walls/floor. Electrical: All cables are correctly terminated in appropriate connection blocks (i.e LV and ELV cables are not mixed up). -
Page 18: Commissioning
Commissioning After the initial installation the system needs to be commissioned, this document will explain and show how to set up and commission an air to water heat pump. Stage 1 - Electrical Check that the system wiring is complete and connected properly before switching on the power to the indoor and outdoor unit. -
