<ul><li>To supply and install Mitsubishi Electric Air conditioning systems based on direct replacement of &#39;as installed&#39; ducted evaporator systems consisting of 2no 14kW Heat Pump (Cooling and Heating) Ducted Units (PEAD-RP140JAQR3), served by 2no outdoor units sited to replace existing condenser positions (PUHZ-ZRP140VKA3).</li><li>The existing secondary ductwork (plenums/louvres etc) to be cleaned and re-used with only minor modification to fit to the new indoor units, it is assumed these ducts are in satisfactory condition.</li><li>&nbsp;The controls will be installed via hard wired remotes (PAR-32MAA-J) as per existing positions with the allowance for interconnection to existing HVAC control panel. &nbsp;Old remotes will be removed from the panel and new remotes installed directly to replace. &nbsp;No allowance has been made to make cosmetic changes to the panel front should there be a slight difference in sizes of the new controllers (not expected to be an issue)</li><li>To install 5 wire &#39;run/fault&#39; adaptors (PAC-SA88HA-EP) to indoor units to allow interconnection to existing wire arrangement in HVAC panel.</li><li>To install 3 wire &#39;on/off&#39; adaptors (3 WIRE ADAPTOR) to the indoor units to allow interconnection to existing wiring arrangement in HVAC panel.</li></ul><p>We have reviewed the existing HVAC wiring schematic and it is clear there is no BMS connection. &nbsp;The engineer on site believed &#39;P1 and P2&#39; connections were related to BMS, but the wiring schematic indicates these connections are the HIGH TEMP alarm thermostat.</p><p>The existing HVAC panel is clearly set up as a &#39;duty/standby&#39; system where one unit runs and the other is periodically flipped to run (lead/lag), with controls to force both units to run on HIGH TEMP or the alternative unit to run on any fault of it&#39;s sister unit within the plant room.</p><p>Although a &#39;fire alarm&#39; interconnection is on the wiring schematic, there is no obvious connection from the site survey it appears this is &#39;looped out&#39;.</p><p>It is assumed for the purpose of this quotation that the HVAC panel including lamps are in satisfactory condition and working for the new interconnection.</p><p>If required we can omit the HVAC panel entirely and just run both units on a set temperature, or for ADDITIONAL costs we can re-design the HVAC panel to work as the client desires.</p><p>Inverter systems have been quoted as they are more environmentally friendly, lowering running costs and extending the systems life.</p><p>The evaporator condensate drainage will remain as per existing arrangement , no pumps have been allowed for (if these are required additional charges will apply). &nbsp;The condenser drainage to the ground (no pumps allowed for), no condenser tray or housing allowed for.</p><p>The electrical supply will remain as existing to condensers with new rotary isolators installed by others&nbsp;.</p><p>Except minor local modifications, pipework&nbsp;and interconnection cabling is to be re-used between evaporator and condenser. &nbsp;It is assumed for the purpose of this quotation that both are in satisfactory condition.</p><p>FGAS&nbsp;certification is included for within this quotation.</p><p>Breakdown</p><p>Decommissioning of units and delivery of materials out of hours - &pound;2,558.40 + VAT</p><p>Supply, installation and commissioning of 2no units (as detailed above) - &pound;12,776.10 + VAT</p><p>Site Protection - &pound;75.00 + VAT</p><p>Waste - &pound;125.00 + VAT</p><p>O&amp;M Manual - &pound;250.00 + VAT</p><table border="0" cellspacing="0" cellpadding="0" align="left"><tbody><tr><td><p>&nbsp;</p></td></tr></tbody></table>
