1.0 General Information
1.1 Introduction
Thank you for purchasing the QLA HC1000 Heater / Circulator. The HC1000 has been
precision engineered and designed to create the optimal testing conditions as described
in the monograph, and be compatible with all dissolution baths.
1.2 Safe Operation
The HC1000 Heater / Circulator has been designed to operate safely with any dissolution
machine. Guidelines for safety provided in this operating manual are to keep the

If the unit is used in a manner not specified by Quality Lab Accessories, the operator
and/or unit may be at risk. Please read the safety information provided and use the
HC1000 Heater / Circulator for its intended purpose only.
Please observe all relevant safety practices during the operation of this unit.
1.2.1 General Safety
Operation of the HC1000 Heater / Circulator involves aqueous liquids in
conjunction with a heating element and electrical components. Improper or
careless use of this unit may create shock, fire, or other hazards which may
cause serious injury to personnel or equipment. The disassembly of this unit
may present an unsafe operating environment.
1.2.2 Electrical Hazards
Electrical components used in the heater / circulator operate at dangerous
voltages. Improper use and/or contact with these electrical components can
cause death or serious injury.
Application of the wrong supply voltage, an improperly wired outlet, or the
absence of proper electrical grounding could create a hazardous environment for
the operator, and cause damage to the HC1000 Heater / Circulator. Be sure to
always use a three-wire outlet with a ground connection adequate to the load
output by the unit, and that complies with all local, state, and federal safety
regulations.

2.0 Unpacking
The HC1000 Heater / Circulator has been packaged to protect the unit from shipping and
handling. Please complete the following steps to unpack your HC1000 Heater / Circulator:
1. Carefully remove all items from shipping container.
2. Check all items for damage that may have occurred during shipping. If any damage
to the unit is evident, please contact both your shipping provider and Quality Lab
Accessories.
3. Check the shipping container for any loose parts before discarding.
4. Place the unit on a clean, dry, and level surface as close to your dissolution bath as
necessary. It is recommended to leave approximately 6 inches of open area behind
the unit to allow for access to the rear power control and hose hookups.
This unit includes electrical components. Please ensure a dry area around the unit
before plugging in the main power supply.
3.0 HC1000 Heater / Circulator Overview
The HC1000 Heater / Circulator was designed to function with any dissolution machine, and
provide precise temperature control of your dissolution bath water, within a range of ambient
temperature to 45°C. Operating functions can be monitored on a front panel display. Set and
current temperature are also displayed on the front panel display. A single button/dial makes
operation of the unit quick and easy.
An optional external temperature probe can also be used for increased accuracy and assurance
of bath temperature. Without the external probe, an internal probe measures temperature with
accuracy of ±.1°C.

1. Ensure power switch (SEE FIGURE 2 / ITEM 1) on the rear panel is in the OFF
position.
2. Connect the power cord to the AC power connector (SEE FIGURE 2 / ITEM 2) on
the rear panel of the unit.
3. Plug the other end of the cord into an outlet of the proper voltage.
The supplied power cord is standardized to the United States. Confirm that any power
cord you use meets all local safety regulations and is rated to carry at least 10 amps.
A circuit breaker triggers an automatic shutdown of the unit if a power surge occurs.
Simply switch off and restart the unit. If the problem persists, contact a QLA Lab
Services Professional or authorized QLA engineer.

4.2 Liquid Connections –Single Bath System (FIGURE 2)
1. Locate your ½” diameter tubing and hose clamps. (Hose kit sold separately).
2. Slip one end of your tubing over the barbed fittings on the inlet and outlet fittings of
your water bath. Slide the tubing as far up the fittings as possible.
3. Slip a hose clamp over the free end of the tubing and secure over barbed fitting.
Tighten each hose clamp to avoid leaks. To avoid damage to the tubing, do not
over tighten.
4. Slip hose clamps over the free ends of tubing, and slide each end onto the INLET
and OUTLET fittings on the rear panel of the unit. Be sure that the hose coming
from the inlet of the water bath is attached to the fitting on the rear of the HC1000
unit labeled OUTLET, and that the hose coming from the outlet of the water bath is
attached to HC1000 fitting labeled INLET. To avoid damage to the tubing, do not
overtighten.
5. Double check that all tubing and hose clamps are fitted correctly.

FIGURE 4
4.3 Liquid Connections –Dual Bath System (FIGURE 3)
When using the HC1000 Heater / Circulator with two dissolution baths, the output is divided
between the two water baths, and then recombined at the inlet. Both water baths share a drain to
ensure equal bath levels.
1. Locate your two short lengths of tubing (Dual bath hose kit sold separately).
2. Slip one end of each over the INLET and OUTLET fittings on the rear panel of the
HC1000 Heater / Circulator. Slip a hose clamp over the free ends of each piece of
tubing, and secure over fittings. To avoid damage to tubing, do not over tighten.
3. Slip a hose clamp over the free ends of tubing and slip each end of tubing over its
own Y connector (supplied in dual bath hose kit). Secure the hose clamps over the
Y connector fittings. To avoid damage to the tubing, do not over tighten.
4. Slip a length of tubing over both branches of the Y connector coming from the
HC1000 Heater / Circulator OUTLET. Slip a hose clamp over the free end of each
piece of tubing, and secure over the Y connector fittings. To avoid damage to the
tubing, avoid over tightening.
5. Slip a hose clamp over the free end of each piece of tubing, and slip the tubing over
the inlet fitting of each water bath. Secure the hose clamps over the fittings. To
avoid damage to the tubing, avoid overtightening.
6. Repeat steps 4 - 5 to attach the HC1000 Heater / Circulator INLET fitting to the
water bath outlets.
7. Using the tubing connected to the drain valve. Slip a hose clamp over the free ends
of tubing and slip the tubing over the drain fitting of each water bath. Secure the
hose clamps over the fittings. To avoid damage to the tubing, avoid over tightening.
8. Double check that all tubing and hose clamps are fitted correctly.
