General Information
These instructions guide you through the installation and operation of this BritTherm™ circulation pump. The UPS2A Commercial is a high efficiency circulator which is perfectly suited to operate in:
• Single zone heating systems
• Multi zone heating systems
• Underfloor heating systems
The pump incorporates a permanent magnet motor with differential pressure control which enables its performance to be aligned with actual system demand.
It has a connection size of 1½" , a maximum head of 8 meters and a port to port distance of 180mm making it perfect for heavy domestic and light commercial applications.

Pump Liquid Control Panel
BritTherm™ pumps require clean, thin, non-aggressive liquids to operate correctly and prevent damage to their internal components.
A diagram of the control panel can be found on the next page, here’s what each of the numbers represent:
1.
Constant Pressure Mode
The liquids used must not contain any solid particles, fibres or mineral oil.
2.
Proportional Pressure Mode
3.
ECO Mode
4.
Air Venting Mode
(Press the setting button for 5-6 seconds)
Liquids running through circulation pumps used on heating systems must comply with the accepted standards of quality especially in domestic applications.

Pressure Curve
3
Operating Modes
The operating point moves back and forth on the constant pressure curve according to the volume of flow from the system.
CP2 to CP5
These 2 speeds are the minimum and maximum in constant pressure mode. The curve is shown in the graph on the previous page.
CP1 & CP6
The operating point moves back and forth on the proportional pressure curve according to the volume of flow from the system. As shown in the graph, the pump pressure is directly proportional to demand.
PP2 to PP5
These 2 speeds are the minimum and maximum in proportional pressure mode. The curve is shown in the graph on the previous page.
PP1 & PP6
PP1 - (Proportional Pressure 1) the duty point moves up/down on the lowest proportional pressure curve. Head pressure is then reduced and increased at falling and rising heating demand respectively.
PP2 - (Proportional Pressure 2) the duty point moves up/down on the highest proportional pressure curve. Head pressure is then reduced and increased at falling and rising heating demand respectively.
CP1 - (Constant Pressure 1) the duty point of the pump moves out or in the constant pressure curve depending on heating demand. Head pressure remains constant irrespective of heating demand.
CP2 - (Constant Pressure 2) the duty point of the pump moves out or in the constant pressure curve depending on heating demand. Head pressure remains constant irrespective of heating demand.

Fault Finding
Before starting any work on the pump please ensure the electricity supply is turned off and cannot be accidentally switched back on at any time.
Fault
Pump doesn’t run at all
Noise in the system
Noise in the pump
Insufficient
Control Panel
Light is off
Only shows power
Lights on for power and pump setting
Lights on for power and pump setting
Lights on for power and pump setting
Cause
A) One fuse is blown
B) The current/ voltage operated circuit breaker has tripped out
C) The pump is defective
A) Failure of electricity supply, might be too low
A) Air in system
Remedy
Replace fuse
Cut in the circuit break
Replace pump
Check the supply falls within the specified range
Vent the system
B) Flow is too high
A) Air in pump
B) Inlet pressure is too low
5
A) Pump performance is too low
Reduce the suction head
Let the pump run, it vents itself over time
Increase the inlet pressure. Check the air volume in the expansion tank if installed
Increase the suction head
