6. We are unclear on what is required for the softeners and reverse osmosis equipment. Please explain the required service for this equipment other than chemistry testing? If repairs are needed for this equipment, will it be purchased outside of this contract?

The boiler plant dose its own repairs on the water softeners.

All purchase will outside of the contract. The plant currently purchases salt from Home Depot by the pallet for the softener system.

For the RO/DI system the HVAC Shop purchases the replacement filters and tanks (canister bottles) and currently plans on having these items available in our normal shop stock.

From the SOW:

The following are the expected operating parameters:

a. Chilled Water loop required to maintain 30% glycol.

b. Heating (hot) Water loop required to maintain 30% glycol.

c. Cooling Tower to have no more than 700ppm of calcium and alkalinity.

d. Boilers are expected to operate continuously or at random at 70% load.

e. Water softeners are required to operate at <0.3ppm total hardness.

The testing and analyzation should include testing for the following as applicable to the systems previously identified above:

1. Conductivity

2. Total Dissolved Solids

3. pH Balance

4. P/M Alkalinity

5. Calcium Hardness

6. Total Hardness

7. Iron
