Suction Pressure Regulator (SPR) Adjustment
Procedures - MAX 20
I m p o r t a n t : All new unit installations require these adjustment procedures. Failure to do so may
not allow the unit to operate at its maximum capacity.
N o t e : The following procedures are for initial settings. Sometimes conditions such as high or low
ambient temperatures may require that the settings be fine-tuned for optimum
performance.
M A X 2 0 units are equipped with a SPR valve located in the evaporator (See illustration below).
The valve is used to limit the load on the standby compressor. This also affects the current draw
of the electric motor. Monitor the current drawn of the electric motor when making this
adjustment to ensure it is below the motor overload relay setting.
1. Install gauge manifold set onto the suction service port at the standby compressor (See
illustration below).
2. Attach an additional compound gauge on suction service port located on copper suction tube
in evaporator to monitor suction pressure going to the SPR valve (See illustration below).
3. Connect clamp on amp meter to T1 (Black) motor wire on a 115V/230V 1 PH unit, or to the leg
of the highest voltage motor wire of a 230V 3 PH unit.
4. Connect standby power receptacle to an appropriate electric power source.
5. Place jumper wire between the 12 and CHB wires at the defrost termination switch to verify
the unit will run in defrost.
6. Start unit and run in defrost on the electric standby compressor until the pressure on the
additional compound gauge attached to the suction service port stabilizes at a pressure
above 45 psig (310 kPa).
7. Check the suction pressure on the gauge attached to the suction service port at the standby
compressor. It should be 24 ± 2 psig (165 ± 14 kPa) without exceeding the following electric
