WARNING
Burn hazard. The pump heating collar gets very hot when it is operating. Do not
touch the heating surfaces when the collar is operating and hot. Failure to observe
this warning may result in burns.
CAUTION
Connector damage or poor electrical connection. Use the fine brush from the tool
box to clean dust and sand out of connectors, terminals and dust caps before
making or capping a connection. Install the dust cap provided with connectors
and terminals whenever a connector is disconnected from its terminal. Failure to
observe this caution may result in connector damage or a poor electrical
connection.
Heat damage from pump heating collar. When operating, the pump heating collar
can get hot enough to melt any part of the pump insulating cover that it is in
contact with. Install the pump heating collar so that its heating surface is
positioned away from the sides where it could come in contact with the cover.
Failure to observe this caution may result in damage to the pump insulating cover.
1. Install a pump heating collar on the raw water Motor-Driven Pump P-2 (if used) and the MF Feed
Pump P-3 as follows (see Figure 15):
a. Wrap the heating collar around the pump case with the heating surface away from the
sides of the pump insulating cover and secure it with its strap.
b. Connect the pump heating collar power cable to any one of the heater connections on its
pump skid junction box. Do NOT connect the pump skid power cable to the TWPS PDP
(power distribution panel) at this time.
