sphere.To ensure maximum compressor unit life, provisions must be made for an adequate supply of
cooling air during installation of the compressor unit. For the same reasons the unit must not be operated
above the maximum ambient temperature.
6.4 Compressor Drive System
6.4.1 Description
The prime mover, which is either a single or three phase electric motor, drives the compressor with a V-
belt. The prime mover is mounted on an adjustable base plate and requires periodic adjustment to
ensure proper V-belt tension.
6.4.2 Checking the Drive Belt
1. The proper belt tension for the V-belt is where the belt does not slip under a full load.
2. A rough value for this is when the V-belt deflects Approximately 3/8” (10mm) when pressed with
thumb pressure between the two pulleys. See Figure 6-3.
3. Readjust a new V-belt after the first twenty-five operating hours.
4. Check for damage or wear every 125 operating hours.

6.4.3 V-belt Tension Adjustment
1. Slightly loosen the bolts holding the prime mover onto the base plate (1).

2. Adjust motor position until the V-belt tension is correct (2).
3. Tighten the prime mover mounting bolts.
