Daikin Dedicated Outdoor Air System WGOV012K1RFBLLB002000S7500

Warning: This filter check requires trained personnel!

Can light be seen through the filter when held up to sunlight or a bright light?

Describe the condition of the filter

Enter the number of days since the last filter change

Install field sensors (outdoor air/humidity sensor is required) and land wires on the provided terminal block. These connections can be located on the left-hand side of the unit.

WARNING: LOCKOUT/TAGOUT all power sources prior to wiring or servicing the unit. Hazardous voltage can cause serious injury or death. Disconnect electric power before servicing equipment. More than one disconnect may be required to de-energize the unit.

Unit configuration settings must be checked prior to operating the unit. A detailed list of all relevant parameters can be found in OM 1308. Settings can be changed with Technician level access either through the Local User Interface (LUI) or Service Tools. The unit does not need to be on in order to use ServiceTools.

Open water valves to full-open position and turn on power to the conditioner.

Loop Water Type, CFM, Static Pressure, and Elevation all require field input. Consult the order submittal or engineering specifications for this information. All installed sensors must be set to ‘Installed’. If trending is desired and an SD card is installed in the main control board, enable trending to track unit performance. The default time period is ‘1 minute’. Installed sensors must be assigned a corresponding analog input. Digital outputs, if used must also be configured.

Using the default setpoints is recommended. These can be changed if desired.

DOAS WSHP units are in the unoccupied mode by default. This is done to ensure that the unit does not run without a certified HVAC technician accessing the LUI or ServiceTools prior to operation. To enter the occupied mode, the LUI Occupancy Command must be changed to either ‘null’ ‘Auto’ or ‘Occupied’. Either change ‘KyOccManCmd’ through the LUI or ‘Occupancy Manual Command’ through the service tool under ‘Setpoints’ and ‘Keypad’.

It is required to perform start-up on two separate occasions. One for cooling/dehumidification and one for heating. It is not recommended to manipulate setpoints to run the unit in both cooling and heating under moderate outdoor conditions.

Due to the zeotropic nature of R-410A, it should be charged as a liquid.

In situations where vapor is normally charged into a system, a valve should be installed in the charging line to flash the liquid to vapor while charging.

Make certain that the recycle or recovery equipment used is designed for R-410A.

Because a water source heat pump operates under a wide range of water and air temperatures, the values printed below are to be taken as suggested pressure and temperatures.

All Daikin water source heat pumps are designed for commercial use.

The units are designed for the cooling mode of operation and fail safe to cooling.

The reversing valve is energized for the heating mode of operation.

Normal maintenance on all units is generally limited to filter changes

Units are provided with permanently lubricated motors and require no oiling

Record performance measurements of volts

Record performance measurements of amps

Record water pressure drop (both heating and cooling)

A comparison of logged data with start-up and other annual data is useful as an indicator of general equipment condition

Periodic lockouts almost always are caused by air or water problems

The lockout (shutdown) of the unit is a normal protective result

Warning: R-410A should be used only with polyester (POE) oil

The HFC refrigerant components in R-410A will not be compatible with mineral oil or alkylbenzene lubricants

R-410A systems charged with the OEM recommended lubricant
