EVACUATING Connect a vacuum pump to the service ports on the outdoor unit valves and evacuate the interconnecting pipework and indoor unit to 1000 microns (1 Torr) or better and allow to be held for a minimum of 15 minutes. After evacuating the indoor unit and interconnecting pipework, open the outdoor unit valves using a 5mm Allen key. - Page 16 HL WIRING DIAGRAM HLR WIRING DIAGRAM -16-...

- Page 24 HL OPERATING INSTRUCTIONS (using Speed Selector Switch and Thermostat) The switches to operate the fan speed and thermostat control are located on the right hand side. The upper knob selects temperature, which is automatically controlled by an internal thermostat that senses return room air. Lower room temperatures can be maintained by turning the knob clockwise, further towards the snow flake.

- Page 27 CONDENSATE PUMP KIT 52600240 This kit is for use on all HL/HLR units for the removal of condensate where gravity drain is not practicable or desirable. The pump is capable of overcoming a resistance equivalent to 5 metres lift. The sensor is arranged so that residual condensate in the sump is kept to a minimum. The kit includes an overflow protection circuit which will prevent further cooling and condensate production if a high condensate level occurs.

- Page 29 LOW PRESSURE HOT WATER COIL KIT This kit provides LPHW heating for HL (526) and HLR (527) indoor units. A control valve is not provided in this kit. Since the coil is upstream of the evaporator, a de-ice thermostat is not necessary on the LPHW coil. It is, however, highly recommended to fit a de-ice thermostat to the evaporator to protect the LPHW coil.
- Page 30 EVAPORATOR DE-ICE THERMOSTAT KIT 52600242 This kit stops the compressor running during cooling mode if the indoor coil starts to ice up, (due to lack of charge, blocked filter or over condensing). This kit MUST be fitted to all HL/HLR units with LPHW coils fitted, to provide protection against the hot water system freezing. ITEM DESCRIPTION ITEM...
