Hi-Q CF 900 series

Description

The CF-900 series high volume air sampling pumps are designed for the sampling air bourne particulate and radioiodine in the environment.
The CF-901, comes standard with a 1½” female straight pipe threaded intake which accepts all HI-Q CF-Series holders (excluding 8 x 10). The models CF-902 and CF-903 have a 4″ threaded ring installed on the air intake to allow for 4” diameter paper only sampling. From the 4” diameter ring an operator has the option of either adapting up to an 8″ X 10″ paper only holder (CFPH-810), or adapting down to a 47mm or 2” diameter combination/paper only holder (CFPH-XX Holders). Upon ordering the CFPH-810 it is recommended that an additional CF-900 Series base plate adapter (used to balance the unit) be purchased as well. Adapting down to any of the CF-Series paper holders requires the use of an FHA-4CF, 4” diameter ring to 1½” FSPT Adapter.

Each unit has a label indicating the designed power requirements. Either 115VAC, 60Hz, or the European version 230VAC, 50Hz. The main components of the CF-900 Series Air Sampling Pumps are: A two stage vacuum blower, an SCR motor speed controller, a 3 wire grounded power cord, motor fuse protection, an electronic, elapsed, resettable hour timer (minutes & tenths upon request) and a precision rotometer. All, of which are housed in a 2 component, polyurethane painted aluminum cabinet housing.

UNPACKING:
Each unit is cushion packed to reduce any possibility of damage in transit. If the carton or unit shows any damage, report it immediately to the shipping carrier and file a damage claim. Each unit is tested and is fully operative when it leaves the factory. If there is a problem call the factory immediately.

SELECTION OF FILTER HEAD:
A wide variety of filter heads from various manufacturers will fit the CF-900 series units. The CF-901, comes standard with a 1½” female straight pipe threaded intake which accepts all HI-Q CF-Series holders (excluding 8 x 10). Models CF-902 and CF-903 come standard with a 4” diameter threaded ring, which can be used immediately as a 4” diameter paper only holder, or adapted down with HI-Q’s FHA-4CF to fit CF-Series type holders. From the standard 4” diameter ring an operator can also adapt up to an 8” x 10” paper only holder, using HI-Q’s CFPH-810. For operation of this unit with the 8″ X 10″ paper only holder, a base plate extender is required (supplied with CFH-810 kit). See: High volume particulate section of this manual for instructions.

INPUT POWER:
The CF-900 series are available in two different voltage ranges: 115 VAC and 230 VAC.
The electrical disconnect for this unit is the power cord. Always unplug the power cord from the electrical outlet before performing any service to the unit.
For 115 VAC units, the power requirements are as follows:
Voltage: 115 V~, 50/60 Hz
Current: 15 A
Power: 1550 W
For 230 VAC units, the power requirements are as follows:
Voltage: 230 V~, 50/60 Hz
Current: 8 A
Power: 1000 W
Explanation of Electrical Symbols:
V~: Volts Alternating Current (VAC)
Hz: Hertz
A: Amps
W: Watts
Φ: Protective Earth Ground
+: Shock Hazard

FUSE:
The CF-900 series are available in two different voltage ranges: 115 VAC and 230 VAC.
Fuses used are as follows:
For 115 VAC operation: 15 A, T, 250V
For 230 VAC operation: 8 A, T, 250V

ENVIRONMENTAL CONDITIONS:
Operating Temperature Range: 0 to 50°C
Storage Temperature Range: -40 to 60°C
Operating and Storage Humidity: 0 to 85% maximum non-condensing

OPERATION:
After affixing the appropriate filter head, plug unit into a 3 wire grounded outlet. Note the timers starting number, or reset the timer to zero by pushing the timer’s reset button. Start the unit and adjust the rotometer reading with the motor speed control pot to the desired flow rate. This high volume pump is intended for use as an intermittent grab sampling pump. The motor manufacturer states that the original motor brush life is between 900- 1200 hours. Replacement brushes, after being seated, generally last between 600-800 hours. HI-Q has found that operating at less than maximum flow extends the brush life.

NOTE: Like all devices designed to move a high volume of air, the CF-900 series is rather loud. Operators should use hearing protection when using the CF-900 series air samplers.

CALIBRATION:
Before being shipped out, each CF-900 series Air Sampler is individually calibrated against a NIST traceable standard at sea level and ambient temperature. It is a good practice however, to occasionally check the rotometer calibration against a secondary source such as a calibrated AFC-XX-Series (HFC-SIDE-XX for CF-902 & CF-903) air flow calibrator. Upon ordering choose the correct “AFC-XX or HFC-SIDE-XX” unit for your flow range and slow measurement units.
With a small flat head screwdriver and the correct flow range AFC-XX or HFC-SIDE-XX unit, fine adjustments to incorrect flow rate readings can be made in the field by tightening or loosening the brass needle valve in the back of the rotometer. For “quick-fix” changes stick a piece of masking tape over the rotometer scale and mark according to in-line Air Flow Calibrator unit.

MAINTENANCE:
The motor in the CF-900 series is a 2 stage, non-lubricated motor-blower which has ball bearings. All of the other components should be maintenance free.
