6 Step 3 — Unit Location — T he following guidelines should be considered when choosing a location for a WSHP unit: • Units are for indo or use only • Locate in areas where ambient temperatures are between 4.
7 Step 4 — Mounting the Unit — Horizontal units should be mounted using the factory-installed hangers. Proper attachment of hanging rods t o building structure is critical for safety . See Fig. 2 and 5. Rod attac hments must be able to sup- port the weight of t he unit.
8 Step 7 — Piping Connections — De pending on the application, there are 3 types of WSHP piping s ystems to choose from: water loop, ground-water and ground loop. Refer to Piping Section of Carrier System Design Manual for addi- tional information.
9 W ater S upply and Quantity — C heck water supply . W ater supply should be plenti ful and of good quality . See T able 2 for water quality guidelines. In all applications, the quality of the w ater circulat ed through the h eat exchanger m ust fall within the range s listed in the W ater Qu ality Guide lines ta ble.

14 Table 3 — E lectrical Data LEGEND POWER CONNECTION — Mak e line voltage connection by connecting the incoming line vo ltage wires to the L side of the CC ter minal as shown i n Fig. 13. See T able 3 for correct wire an d maximum overcurr ent protect ion sizing.
15 PSC (PERM ANENT S PLIT CAP ACIT OR) BLO WER SPEE D SELEC TION — All W at er Source Heat Pumps are fac tory set to deliver rated ai rflow at nominal stat ic (37 Pa) on medium speed. Where higher static i s needed, high spee d can be utilized (100 to 125 Pa).
16 Step 9 — Low V olta ge Wiring (See Fig. 15) TH E RM O S T A T C ON N EC T I O NS — The thermostat should be wired directly to the Aquazone™ cont rol board. See Fig. 9-12. W A TER FREEZE PROTECTION — The Aquazone control allows the field selection of source fluid freeze protection points through jumpers.
17 AI R C O IL — T o obtain maximum perfor mance, clean the air coil before starting the unit. A ten percent sol ution of dish- washing detergent and w ater is recommende d for both sides of the coil.

19 Scro ll Compressor Rotation — It is important to be cer tain com presso r is rotati ng in the pr oper di recti on. T o determine whether or not compre ssor is rotating in the pr oper direction: 1. Connect service gages to suction and discharge pressure fitt ings .
20 Table 9 — Typi cal Uni t Operatin g Pres sures and T emperat ures LEGEND NO TES: 1. Based o n nomin al 54 L /s per kW air flow and 21 ° C EA T heati ng and 2 6.7/ 194° C EA T cool ing. 2. Cooling ai r and wa ter n umber s can v ary great ly with c hang es in hum idit y .
21 Anti free ze — In areas where ent ering loop temperatures drop below 4.4 C or where piping will be routed through areas subject to free zing, antifreeze is needed. Alcohols and glyc ols are commonly used as anti freeze agents. Fr eeze prot ection shoul d be mainta ined to 8.
22 Output EH2 will be off if FP1 is greater than 7.2 C and FP2 (when shorted) is great er than 43.3 C during Heating Stage 3 mode. This condition will have a 30-second recognition time. Also, during Heating Stage 3 mode, EH1, EH 2, Fan Enable, and Fan Speed will be ON i f G input is not active.
23 Retry Mode — In Re try mode, the status LED will start to flash slowly to signal that the control is trying to recover from an input fault. The control will s tage off the outputs and try to again satisfy the thermostat used to terminal Y . Once the ther- mostat input calls are satisfied, the control will continue normal operation.
24 Condensate Drain P ans — Chec k condensate drain pans for algae growth t wice a year . If algae growth is apparent , consult a water treatment speci alist for proper chemic al treat- ment. Applying an algaecide every three months will typically eliminate algae problems in most locations.
25 5. Read liquid line temperature on thermometer; then subtract from bubble point temperature. The di fference equals subcooling temperatu re. 6. Compare the subcooling temperature with the normal temper ature li sted in T able 9.
