<br />12
<br />power and controls cables and mount any new devices prior to final
<br />RC
<br />connections being made in order to reduce the amount of "down
<br />time" needed to complete the installation.
<br />If the new KE2 panel is being retrofitted to an existing walk-in box,
<br />13
<br />ensure that the walk-in box door is kept closed as much as possible
<br />RC
<br />during the time in which the conversion work is being carried out.
<br />14
<br />Notify the WMT building controls team and advise them which
<br />RC
<br />system and which walk-in box will be impacted by the work.
<br />Mount the standard KE2 evaporator control panel on the external
<br />wall of the freezer to which the controller is connected. Install the
<br />15
<br />panel on the door wall of the box, in an accessible position that is
<br />RC
<br />out of the way of traffic which may damage the panel. Note that
<br />panels must be installed with NEC required clearances.
<br />16
<br />Use the existing defrost circuit to power the KE2 Therm panel.
<br />RC
<br />Carry out the electrical installation in line with the manufacturer's
<br />17
<br />instructions and information included on the blue prints (if
<br />RC
<br />applicable).
<br />If existing circuit control valves are located at the rack, remove the
<br />circuit LLSV from the liquid manifold at the rack and provide a
<br />18
<br />new LLSV to be installed in the evaporator liquid line pipework
<br />RC
<br />located above the walk-in box. Remove the mechanical suction stop
<br />valve from the rack and provide a new EEPR to to be installed in the
<br />evaporator suction line pipework located above the walk-in.
<br />If installing more than one KE2 Therm panel in a single facility,
<br />follow the manufacturer's instructions to "bond" the panels
<br />19
<br />together. This bonding process prevents evaporators from different
<br />RC
<br />walk-ins from defrosting concurrently, which may overload the
<br />electric defrost power circuit.
<br />If the evaporator has an electronic expansion valve (EEV) connect
<br />20
<br />the valve to the correct terminals within the KE2 Therm evaporator
<br />RC
<br />controller.
<br />21
<br />Program the controller in accordance with guidance given in the KE2
<br />RC
<br />Therm installation materials.
<br />22
<br />Carry out the BAS controls parameter changes and perform a
<br />EMS
<br />remote checkout.
<br />The KE2 Therm evaporator control panel executes all temperature
<br />control and defrost functions. Therefore, it is essential that all of the
<br />temperature control and defrost functions for the walk-in
<br />23
<br />evaporator are removed from the existing BAS controls system.
<br />RC
<br />Apart from a defrost signal cable that must be installed from the
<br />KE2 to the BAS system when indicated on the prints, no other
<br />functions for the walk-in are to remain in the BAS system.
<br />24
<br />1 Furnish controls support to the installing contractor.

<br />If the walk-in box has a refrigerant leak detection system, connect
<br />25
<br />the signal from the leak detection system to the appropriate
<br />RC
<br />terminals at an input module connected to the same network
<br />gateway as the KE2 Therm panel.
<br />in the event of any questions or concerns regarding correct
<br />26
<br />installation, set up or programming of the panel, contact NOVAR
<br />RC
<br />(NOVARTEC28@wal-mart com, 800-341-7795).
<br />27
<br />Notify WMT building controls that the walk-in box is running and
<br />RC
<br />online.
<br />28
