KEYED NOTES - MECHANICAL:

DEMOLITION

Remove exhaust fan ducting to make room for new condenser water pump. After new pump is installed, duct will be rerouted

and reinstalled.

Remove condenser water pump and condenser supply and return water piping inside mechanical room. All condenser water

piping in room is to be removed from the chiller up to the flange before pipe penetrates roof. The CWS pipe through roof to

remain from flanges on each side of roof. CWR pipe through roof to be removed through aluminum jacket sleeve and the

sleeve capped.

Existing Cooling Tower CT-2 will be moved and reoriented to make room for new Cooling Tower CT-1. Remove condenser

water supply and return water piping indicated. Provide pipe support for existing condenser water supply and return piping to

remain before demolition. Remove pipe insulation and heat trace. Remove tower drain piping and overflow piping from

tower to permanent drain pipe in ground. Set CT-2 down to allow demolition of existing tower supports. Cooling tower shall

not be set directly on gravel, provide substantial blocking at all support points. Remove existing cooling tower concrete

block support and footings. After demolition is complete, begin work immediately to reinstall tower.

Remove existing make up water piping back to isolation valve in mechanical room.

Existing tower water treatment equipment to be reused. Remove stand housing the equipment during demolition. The best

location to reinstall the stand is to be determined after new piping is installed. Blow down solenoid valve to be reused.

Remove all wiring including conduit along floor after review. The obsolete and unused tower treatment equipment that is

mounted on the wall is to be removed.

Existing tower drain piping and vent are to be reused. Remove the vent during construction and replace after work is

complete. Reroute and support vent as necessary.

Alternate M-1: The 3 building chilled water zone pumps (P-9, 10 & 11) are to be removed along with chiller pump (P-13). A

new chiller pump (P-13) will be installed at the same location. The building pump take off with 6” piping to existing pump

P-9 is to be reused for one new building pump (P-9). Cap other take offs. The supply of the new building pump (P-9) will be

routed and tied into the three zone supply pipes. Refer to the Detail 3/M-500 - Alternate M-1 Chilled Water Pump

Replacement Schematic.

Remove existing Cooling Tower CT-1 and condenser supply and return water piping on roof. All condenser piping aboveroof is to be removed from the cooling tower down to the flange before pipe penetrates roof. The CWS pipe throughroof to remain from flanges on each side of roof. CWR pipe through roof to be removed through aluminum jacket sleeveand the sleeve capped.

Existing steel support frame to remain.

Remove make-up water piping from cooling tower down through roof. Cap pipe sleeve after pipe removal.

Remove electrical conduit and conductors from cooling tower back to starter in mechanical room. Conduit through roofcan remain. Cap conduit 1' above roof. Refer to electrical drawings.

Provide new condenser water pump P-12 and diverting valve just inside wall. Refer to Detail 2/M-102. Adjust location to

allow a minimum of 4" of wall between short door and new pipe. Provide 6" condenser water piping to chiller and cooling

tower. Install 3/4" taps and valves for water treatment and thermometer wells for sensors. Sensors will be installed in

separate project. Reinstall chiller flow switch.

Rotate 90° duct radius and extend duct down to 12" above floor at location shown. Install sheet metal down to floor on sides

facing the door and chiller.

Using existing heat trace circuit, wire all piping heat trace through new outdoor thermostat.

Alternate M-1: Replace existing chiller pump (P-13). Provide new constant speed pump chiller pump (P-13). Replace three

existing chilled water pumps (P-9, P-10 and P-11). Provide one new chilled water building pump (P-9) with VSD. Pipe new

pump outlet to all three zone supplies. Refer to Detail 3/M-103.
