Frequently Asked Questions King KV801 & KV802
VAC Plug and Receptacle that suits your facility.
- Minimum 20 amp dedicated
Circuit for the KV802, and a 15 amp dedicated Circuit for the KV801 (if not dedicated then must be shared with minimal draw equipment).
- Dry, clean air or
nitrogen with a hose that fits a ¼” hose barb on the back of the instrument.
- Dry air/nitrogen pressure
set to approximately 5 PSI or 0.5 SCFH.
- The KV802 and KV801 requires just over two
gallons of pure, fresh methanol (no more than 5% water content).
- The instrument will need to have at least 8” (20 cm) of
counter space on both sides, and 12” (30 cm) on the back of the unit with no
obstacles blocking the vents – this is needed to allow for proper air flow for
the refrigeration system.
- The bath
dimensions are approximately 27”L x 17”W x 40”H (68 x 43 x 102 cm). The height includes room for the mounting
assembly and Viscometer. The KV802 and KV801 height is 25” (63 cm).
- Typical cleaning
solvent such as Cyclohexane (to remove oil from parts after testing).
- Lab temperature no
greater than 80° F.
- Ensure the air space between the bath, walls and other
instruments is as follows: A minimum of 8” (20 cm) on either side and 12” (30
cm) at the back of the bath. If there are instruments next to the KV Bath that
exhaust heat, consider positioning the instruments away from each other.
- With the bath at room temperature, remove the Carousel
and verify the vortex in the bath medium is 1/2 to 3/4 of the way down into the
- Check the moisture content of the bath medium with a hydrometer–
if it is above 5% the bath medium must be changed.
- Perform a crash cool: With the bath set at 0˚C, turn the bath, heating, and cooling ON until it reaches
temperature. Then turn the heat OFF. If
it takes longer than indicated on the Cooling Curve Certificate in the Operations
Manual, there could be a refrigeration or other issue.
- Be sure lab temperature is not greater than 80°F.
- If you are still experiencing temperature
variations, contact King Refrigeration Technical Service.
