NOTES:

1. THE OUTLET OF THE RECEIVER MUST BE HIGHER THAN THE ELEVATION

OF THE EEV INSIDE THE CRAC UNIT; THE VERTICAL HEIGHT MUST NOT

EXCEED 60 FT; VERIFY EXACT HEIGHT OF EEV IN THE FIELD.

2. FOR PROPER PUMP FUNCTION, A MINIMUM ELEVATION DIFFERENCE OF 60

IN. MUST BE MAINTAINED BETWEEN THE BOTTOM OF CONDENSER COIL

TO THE BOTTOM OF PRE UNIT.

3. THE MAXIMUM EQUIVALENT PIPING BETWEEN ACC AND PRE UNIT IS 25 FT;

PRE UNIT MUST BE MOUNTED OUTDOOR FOR PROPER OPERATION.

4. UNIT MUST BE TRAPPED AT THE BOTTOM OF RISER WITH ANY RISE OVER

5 FT HIGH; IF RISE EXCEEDS 25 FT, THEN A TRAP IS REQUIRED IN 20 FT

INCREMENTS OR EVENLY DIVIDED.

5. PITCH HORIZONTAL HOT GAS PIPING AT A MINIMUM OF 1/2" PER 10 FT SO

THAT GRAVITY WILL AID IN MOVING OIL IN THE DIRECTION OF

REFRIGERANT FLOW.

6. UNIT PIPING ENTRANCE VARIES BY UNIT AND MAY BE THROUGH THE TOP

OF THE UNIT.

7. ALL INDOOR AND OUTDOOR FIELD REFRIGERANT PIPING MUST BE

INSULATED, 1" MINIMUM; ALL OUTDOOR INSULATION MUST BE UV AND

OZONE RESISTANT; ALL OUTDOOR PIPING MUST BE WRAPPED W/

ALUMINUM JACKET.

8. LIQUID LINE FROM RECEIVER TO PRE UNIT 1-3/8" MINIMUM; DO NOT TRAP

THIS LINE; SLOPE 2" PER 10 FT DOWN TOWARDS PRE UNIT.

9. CONSULT FACTORY FOR ANY EXCEPTIONS TO THE ABOVE GUIDELINES.

10. REFER TO MANUFACTURER'S INSTRUCTION FOR PROPER PIPING

INSTALLATION.
