restrictive. Filters/purifiers with high pressure drop may
require a separate line and the installation of an accu-
mulator tank in the system.

WINTERIZING YOUR WATER SYSTEM
To winterize, it is not necessary to drain the water from
the entire water system. Blowing into the lines to remove
the water from your water system is not satisfactory due
to the check valve mechanism built into the pump.
Follow these steps to remove all water from your water
system:
1. Drain water by opening tank drain, or open a fixture to
allow pump to operate until tank is dry.
2. Open the lowest outlet in water system to drain lines.
3. To remove any remaining water (about a cup), remove
outlet hose on pump and activate pump. To blow out
lines, attach air nozzle where outlet hose was
removed. Make sure all fixtures are open before starting.
4. Your water system is now winterized. Don’t forget to
reattach the outlet hose to pump and close all fixtures.
PAR-MAX pumps have thermal overload protected motors. The motor will automatically shut off as
temperature rises due to an overload condition. If the motor shuts off in this manner, close all nozzles, faucets or
valves. After a cooling off period, the pump will automatically re-start.
DO NOT USE AUTOMOTIVE TYPE ANTI-FREEZE. IT IS POISONOUS. USE OF THIS TYPE ANTI-
FREEZE WILL CAUSE SERIOUS INTERNAL INJURY OR DEATH.
