5.0 INSTALLATION OUTDOORS
The “dia-Pump” is a totally enclosed pump, which can be used outdoors or indoors. When installed out-
doors, make sure that the pump is protected against extremes of nature as follows:
5.0.1 Running of the pump when exposed to tropical sunshine with ambient temperature above 90°F
(32°C) would cause excessive oil and motor temperatures. The pump should be shaded and
located in such a way as to permit an ample degree of air circulation.
5.0.2 Under cold conditions, the pump should be insulated and a heater should be supplied in order
to maintain the hydraulic fluid at an ambient temperature above 30°F (—1°C.)
