Daikin ENVi Thermostat Installation Manual Step! By Imran

Daikin ENVi Thermostat Installation ManualStep
. Position and Wire the DPCA The Daikin Power and Communication Adapter (DPCA) provides an interface between the thermostat and Indoor Unit. To install the DPCA: 1. Position the DPCA in a suitable location, away from water and near the Indoor Unit (for example, a backside cavity of a wall-mounted unit). The DPCA is not plenum rated and should be mounted in a non-plenum space. 2. Connect the DPCA power cable to the Indoor Unit power supply terminals. Ensure that the electrical connections are securely tightened. 3. Remove the DPCA cover by grasping both sides and pulling along the length of the DPCA. 4. Use the Wiring Harness to connect the P2 terminal on the DPCA to the S21 terminal on the Indoor Unit’s main PCB. Refer to the Daikin system installation manual for information about accessing the S21
Step 3. Install the Daikin ENVi Thermostat The ideal location for the thermostat is approximately 5 ft (1.5 m) above floor level in the main living area. Do not install the thermostat: Close to sources of heat such as incandescent lights Near supply heating/cooling sources In direct sunlight On exterior, non-insulated or poorly insulated walls In the kitchen or other areas of potentially high heat and/or humidity In an area that could restrict air flow To install the thermostat:
1. If necessary, remove the previous thermostat. 1. Gently separate the backplate from the Daikin ENVi thermostat. 2. Place the thermostat backplate on the wall. Make sure that any existing wires can be inserted through the opening for the wiring. If the backplate does not adequately cover the area where the previous thermostat was installed, attach the trim plate to the back of the backplate to increase its coverage. 3. Using the backplate as a template, mark the location of the

AHU PRE-FILTER FUNCTIONS! By Imran

PRE-FILTER FUNCTIONS
Pre-filters are a nice feature to have in your air purifier. It also expands the lifetime of HEPA and activated carbon filters which follow after pre-filter. The pre-filter is the front line in an air purifier, and it captures largest particles which the primary filter usually can’t do. Pre-filters come as a very handy feature that strengthens air filtering technology by preventing debris getting into the next, primary filter. Pre-filters usually have a long lifetime because they can be washed, vacuumed and replaced whenever it`s necessary. If your air purifier is running all the time, then it`s recommended to clean the pre-filter at least one a month. Otherwise, pollution such as fur, pollen, dust and hair will get stucked in the pre-filter after a while, and it will dramatically decrease the overall performance of an air purifier. Washable filter is a great plus, which will save you a lot of money long term
Eventually, after a longer period, the pre-filter will wear out, after many times of cleaning it, and active air-purifying day after day. So, if you want to keep it safe then buy a new pre-filter and change the old one, when you feel that it is necessary.
