COMMISSIONING
ONLY BY CERTIFIED AMERIWATER REPRESENTATIVES.
This Reverse Osmosis System (RO) contains a preservative solution to
prevent microbiological growth and freezing. Discard all product water for
at least two hours of operation before placing the RO in service.
5.4.1
Pretreatment Lockout
The
MediQA can utilize pretreatment lockout. Pretreatment lockout will prevent
the device from operating while the pretreatment is going through regeneration.
The MediQA is shipped from the factory with a jumper installed between wire
terminal X24 and wire terminal 1. To enable the pretreatment lockout
functionality, remove the jumper wire between wire terminal X24 and wire
terminal 1. After removing the jumper wire, wire the normally closed side of the
pretreatment lockout switch or switches (located in the pretreatment controller)
as shown below.
Note: This diagram can be adapted for any number of devices so long as when
any one opens, the connection to the MediQA is opened.
Failure to remove the jumper between X24-1 will prevent pretreatment
lockout. This will allow the MediQA to operate at all times, regardless
of the status of the pretreatment.
5.4.2
Heatsan Water Loss Lockout
Heatsan water loss lockout will prevent the MediQA from operating while the
water loss alarm is active on the Heatsan. This feature stops the flow of water to
allow a leak to be dealt with. Once the leak is fixed, the alarm can be cleared on
the Heatsan and confirmed on the MediQA. This feature is enabled by the MINT
cable connection between the Heatsan and the MediQA.
